NOAA Ocean Acidification - The Other Carbon Dioxide Problem
Fundamental changes in seawater chemistry are occurring throughout the world's oceans. Since the beginning of the industrial revolution, the release of carbon dioxide (CO2) from humankind's industrial and agricultural activities has increased the amount of CO2 in the atmosphere. The ocean absorbs almost a third of the CO2 we release into the atmosphere every year, so as atmospheric CO2 levels increase, so do the levels in the ocean. Initially, many scientists focused on the benefits of the ocean removing this greenhouse gas from the atmosphere. However, decades of ocean observations now show that there is also a downside — the CO2 absorbed by the ocean is changing the chemistry of the seawater, a process called ocean acidification. This change in the ocean's chemistry will have profound effects on life in the ocean, and those who depend on it.

Ocean Acidification
In this video Paul Andersen shows how carbon dioxide in the atmosphere is causing a decrease in the pH of the oceans. The carbon dioxide combines with the water to create carbonic acid which dissociates into bicarbonate and carbonate anions. Decreased pH leads to lower metabolism and immune response in marine species. Increased bicarbonate makes it difficult to form shells and reefs of calcium carbonate.

But many climate-change alarmists seem to claim that all climate change is worse than expected. This ignores that much of the data is actually more encouraging than expected. Yes, Arctic sea ice is melting faster than the models expected. But models also predicted that Antarctic sea ice would decrease, yet Antarctic sea ice is increasing. Yes, sea levels are rising, but the rise is not accelerating—if anything, two recent papers, one by Chinese scientists published in January 2014, and the other by U.S. scientists published in May 2013, have shown a small decline in the rate of sea-level increase. We are often being told that we’re seeing more and more droughts, but a study published in March 2014 in the journal Nature actually shows a decrease in the world’s surface that has been afflicted by droughts since 1982. Facts like these are important because a one-sided focus on worst-case stories is a poor foundation for sound policies. Hurricanes are likewise used as an example of things getting worse. But look at the U.S., where we have the best statistics: if we adjust for population and wealth, hurricane damage during the period of 1900-2013 actually decreased slightly. At the U.N. climate conference in Lima, Peru in December 2014 attendees were told that their countries should cut carbon emissions to avoid future damage from storms like Typhoon Hagupit, which hit the Philippines during the conference, killing at least 21 people and forcing more than a million into shelters. Yet the trend for strong typhoons around the Philippines have actually declined since 1950, according to a study published in 2012 by the Journal of Climate. Again, we’re told that all things are getting worse, but the facts don’t support this. This does not mean that global warming is not real, or a problem, but the one-sided story of alarmism makes us lose focus. If we want to help the world’s poor, who are the most threatened by natural disasters, it’s less about cutting carbon emissions than it is about pulling them out of poverty. The best way to see this is to look at the world’s deaths from natural disasters over time. In the Oxford University database for death rates from floods, extreme temperatures, droughts, and storms, the average in the first part of last century, was more than 130 dead every year per million people. Since then, the death rates have dropped 97 percent to a new low in the 2010s of less than 4 per million. The dramatic decline is mostly due to economic developments that help nations withstand catastrophes. If you’re rich like Florida, a major hurricane might cause plenty of damage to expensive buildings, but it kills few people and causes only a temporary dent in economic output. If a similar hurricane hits a poorer country like the Philippines or Guatemala, it kills many more people and can devastate the economy. So let’s be clear. Climate change is not “worse than we thought.” That doesn’t mean it’s not a reality or not a problem. It is. But the narrative that the world’s climate is changing from bad to worse is unhelpful alarmism that prevents us from focusing on smart solutions.

Rising sea levels threat from global warming - climate change, carbon dioxide and melting of ice caps - impact on Netherlands, Bangladesh and coastal cities

NASA | A Year in the Life of Earth's CO2
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons. The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office. The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006. While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.

Sea level rise estimates doubled
Brady Dennis and Chris Mooney from The Washington Post, recently reported on updated sea level rise projections. Sea levels could rise nearly twice as much as previously predicted by the end of this century if carbon dioxide emissions continue unabated, an outcome that could devastate coastal communities around the globe, according to new research published Wednesday. The main reason? Antarctica. Scientists behind a new study published in the journal Nature used sophisticated computer models to decipher a longstanding riddle about how the massive, mostly uninhabited continent surrendered so much ice during previous warm periods on Earth. They found that similar conditions in the future could lead to monumental and irreversible increases in sea levels. If high levels of greenhouse gas emissions continue, they concluded, oceans could rise by close to two meters in total (more than six feet) by the end of the century. The melting of ice on Antarctica alone could cause seas to rise more than 15 meters (49 feet) by 2500. The startling findings paint a far grimmer picture than current consensus predictions, which have suggested that seas could rise by just under a meter at most by the year 2100. Those estimates relied on the notion that expanding ocean waters and the melting of relatively small glacierswould fuel the majority of sea level rise, rather than the massive ice sheets of Greenland and Antarctica.

How Do We Know That Adding Carbon Dioxide To The Atmosphere Causes A Temperature Rise?
The Arctic may be free of ice for the first time in 10,000 years. Wadhams shows how sea ice is the 'canary in the mine' of planetary climate change. He describes how it forms and the vital role it plays in reflecting solar heat back into space and providing an 'air conditioning' system for the planet. Prof. Peter Wadhams is the UK’s most experienced sea ice scientist, with 48 years of research on sea ice and ocean processes in the Arctic and the Antarctic. This has focused on expeditions and measurements in the field, which has involved more than 50 expeditions to both polar regions, working from ice camps, icebreakers, aircraft, and, uniquely, Royal Navy submarines (6 submerged voyages to the North Pole ). His research group in Cambridge has been the only UK group with the capacity to carry out fieldwork on sea ice. He is Emeritus Professor of Ocean Physics and is the author of numerous publications on dynamics and thermodynamics of sea ice, sea ice thickness, waves in ice, icebergs, ocean convection and kindred topics. The current main topics of research in the group are sea ice properties, dynamics, and distributions in thickness and concentration. He is also a pioneer in the use of AUVs (autonomous underwater vehicles) under sea ice, using multibeam sonar to map bottom features, work which he has also been done from UK nuclear submarines. He began his research career at the Scott Polar Research Institute, Cambridge University, where he rose to become Director. He moved to DAMTP in 2001. He has also held visiting professorships in Tokyo (National Institute of Polar Research), Monterey (US Naval Postgraduate School), Seattle (University of Washington) and La Jolla (Green Scholar at Scripps Institution of Oceanography). He was the coordinator of several European Union Arctic flagship projects (ESOP, GreenICE, CONVECTION, and others) and is currently on the Steering Committee of the EU ICE-ARC project as well as a major US Office of Naval Research initiative in the Arctic. He served eight years on the Scientific Committee of the European Environment Agency and had served on panels of the National Academy of Sciences (USA). In 1990 he received the Italgas Prize for Environmental Sciences, and he has also been awarded the Polar Medal (UK) (1987) and the W.S. Bruce Prize of the Royal Society of Edinburgh. As well as being Professor at Cambridge he is an Associate Professor at the Laboratoire d’Océanographie de Villefranche, run by Université Pierre et Marie Curie, Paris, and is a Professor at the Università Politecnica Delle Marche, Ancona. He is a Member of the Finnish Academy and is a Fellow of the Royal Geographical Society. His most recent book, “A Farewell to Ice”, documents the ways in which the retreat of sea ice in the Arctic generates feedbacks which impact the entire global climate system, accelerating the rate of warming, the rate of sea level rise, the emission of methane from the offshore, and the occurrence of weather extremes affecting food production. He contends that catastrophic consequences cannot be avoided without making an all-out effort to develop ways of directly capturing carbon dioxide out of the atmosphere.

Sea Levels Rise Too Fast To Reverse Climate Change, Says Study
Join #FOWLERNATION!! http://bit.ly/14crV4D By the time climate change reduces crop yields or frequently floods New York City subways, it would be too late to avert damage without better forecasting tools, a panel of scientists said in a report released today. Dangerous rises in the sea level or heat waves that kill crops can arrive quickly and leave little time to put preventative measures in place, according to a study from the National Research Council, a group of scientists providing information for U.S. government decision-makers. The report -- one of two issued today on climate change -- calls for an early warning system to monitor climate conditions and improved models for predicting changes that impact the way people live. The alerts could be modeled on such programs as the National Integrated Drought Information System created by Congress in 2006 or the U.S. Agency for International Development's Famine Early Warning System Network. "It's important to look down the road and try to identify what are the abrupt changes that we can plan for with some degree of confidence, and then make the best of them rather than having them hit us in the face," said Anthony Barnosky, professor of integrated biology at the University of California in Berkley and a co-author of the report. Hansen Report In a separate report today, James Hansen, who warned of the dangers of global warming as early as 1988, said a United Nations-endorsed target of capping global warming is too high and will ensure future generations suffer "irreparable harm." Even limiting warming to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial times would submerge coastlines, cause the mass extinction of species and trigger extreme weather, according to Hansen, former director of the NASA Goddard Institute for Space Studies and co-author of the report published today in the journal PLOS One. Quick action, including a fee on carbon dioxide emissions and the expansion of nuclear power, is needed to prevent the worst impacts of climate change, according to the paper. "Two degrees Celsius warming above pre-industrial, which would mean about 1 degree Celsius warming above the present, creates a significantly different planet with enormous consequences, including eventually the un-inhabitability of coastal cities," Hansen, adjunct professor at New York's Columbia University's Earth Institute, said at a briefing. "There's no recognition of this in government policies." Ocean Monitoring The planet's rapid warming is already producing adverse results. The loss of Arctic sea ice is under way as atmospheric levels of carbon dioxide continue to rise, according to Barnosky. Other impacts, such as sea-level rise from ocean warming, will probably to take longer and may be predicted with better satellite data and ocean monitoring. "There's nothing in place to put all the pieces together in a way that really integrates the information to make it meaningful for this sort of longer-term prediction," Barnosky said. Barnosky recommends that the U.S. government create an Abrupt Change Early Warning System using many existing resources. Record carbon emissions have lifted the Earth's temperature about 0.8 degrees Celsius (1.4 degrees Fahrenheit) since the industrial revolution, and the planet is on a path to exceed the UN-endorsed maximum of 2 degrees Celsius of warming by 2100. Scientists say as a result, sea levels are rising and oceans are acidifying.

Sea Level Sinks. AlGoReal CO2 Hoax

Hae lisätiedot ja faktat tältä blogisivultani http://wp.me/px1AT-Gs Water is a fluid. Right? When earth surface rise 'higher', water tends to escape lower places. Sea surface north from Scandinavian Kvarken drops 1,32m per 100 yrs, - FOUR FEET 4" - sea escapes / land rises ... States pull hefty levies from landowners from the newly revealed landmass... only from beach landowners (as ground under sea 'belongs' to the STATE) ... taxing from SEA level DROP. AlGoRealism (MSM programmed mass hysteria) has based the immense CO2 taxes on this sea level rise hoax. Taxing all of us from SEA LEVEL RISE. This global tax ending in vat-i-can coffers is possible only via global UN gvmt - papal new world order. This imaginative video's Kvarken -simulation has never been done. Why? Because every University on this Earth is under strict financial CO2-umbilical cord. If somebody tries to simulate and prove how sea levels are falling somewhere, like in Scandinavia, that researcher will find himsel on the 'mile-mfg plant'.

Here is just one linky www.absoluteastronomy.com/topics/Kvarken One of the hillaryous details are hidden in polar bear census: "they are on the brink of exctintion" ... err via multiplying. 1950 census was 2500 bears, 2005 census was 25.000. Unbearable. RIGHT!? http://www.kvarkenguide.org/geologien.html Merenkurkku=Kvarken. Katso www.kvarkenguide.org Geologit kertovat että Pohjanlahdesta tuleekin järvi vuonna 2500, alueen nousu tulee olemaan vielä yli 100metriä. Kas tuostahan vesi säikähtää ja pakenee kaukomaiden saarille... The thick ice sheet, which was three kilometres at its thickest, pressed the earth's crust 800 to 1,000 metres downward. When the ice began to melt the crust began to lift to reach its previous position. The land uplift rate in Kvarken is currently 8 to 8.5 mm per year. At this rate, the flat coastal and archipelago landscape noticeably changes during a single generation. Bridges and boathouses wind up on dry land, waterways become shallow, inlets are cut off from the sea and new underwater banks emerge. Scientists expect the land to rise another 100 to 125 metres. In about 2,500 years this will result in a land bridge across the Kvarken strait. The development will be quite different if the greenhouse effect becomes reality, with the level of the sea rising as the polar ice cap begins to melt due to global warming. This scenario would counter the effects of the land uplift. Terranova - Kvarken Nature Centre Terrranova, "the new land", depicts the land uplift, Kvarken's nature and nature conservation areas, and provides information about outdoor activities and nature tourism in the area. Terranova - Kvarken Nature Centre is located in the Ostrobothnian Museum. .

Effects of Sea-Level Rise on Coastal Wetlands in the Mississippi Delta
Visit: http://gallery.usgs.gov/videos/257 for more information. This video describes research being conducted by Dr. Karen McKee, USGS Research Ecologist, and her university partner, Dr. Julia Cherry. Their goal is to better understand the effects of sea-level rise and other global change factors on coastal wetlands in the Mississippi River Delta. This region contains over 40% of the U.S. wetlands in the lower 48 states These wetlands support commercial fisheries, provide habitat for waterfowl and wildlife, and act as storm buffers, protecting several important ports and cities such as New Orleans McKee and Cherry are conducting field and greenhouse experiments to quantify how plant productivity contributes organic matter to vertical soil building, which helps to counterbalance sea-level rise. They are also investigating how elevated concentrations of carbon dioxide in the atmosphere may stimulate plant production and help marshes build vertically and avoid submergence. Their research is contributing to a better understanding of how coastal wetlands persist in the face of changing sea levels and how they may respond in the future.

CO2 Passes Milestone Level
For the first time in human history, the concentration of climate-warming carbon dioxide in the atmosphere has passed the milestone level of 400 parts per million (ppm). The last time so much greenhouse gas was in the air was several million years ago, when the Arctic was ice-free, savannah spread across the Sahara desert and sea level was up to 40 metres higher than today. http://www.guardian.co.uk/environment/2013/may/10/carbon-dioxide-highest-level-greenhouse-gas The CO2 graphs: http://www.guardian.co.uk/environment/interactive/2013/may/10/climate-warming-gas-carbon-dioxide-levels-interactive Subscribe to The Daily Conversation http://bit.ly/WZnLnd Join the conversation on Facebook http://www.facebook.com/thedailyconversation Add TDC to your circles on Google+ https://plus.google.com/100134925804523235350/posts Follow The Daily Conversation on Twitter http://www.twitter.com/thedailyconvo There's scary news this week that climate warming gas in our atmosphere has passed the 400ppm milestone--higher than it's ever been in at least the last 3 million years, a period known as the Plicocene when global temperatures were 3-4 degrees celcius higher than they are today. "The passing of this milestone is a significant reminder of the rapid rate at which -- and the extent to which -- we have increased the concentration of greenhouse gases in the atmosphere," said Prof Rajendra Pachauri, chair of the Intergovernmental Panel on Climate Change, which serves as science adviser to the world's governments. "At the beginning of industrialisation the concentration of CO2 was just 280ppm. We must hope that the world crossing this milestone will bring about awareness of the scientific reality of climate change and how human society should deal with the challenge." These charts show just how frightening this moment is for humanity, which has seen CO2s levels growing at an ever-increasing rate. Zooming out really shows the true scope of this problem if we don't get it under control and quick. We're basically suffocating ourselves and all the other life on our planet. If global temperatures rise by more than 2C, Earth will lose more than half of the common plant species--the less plants we have, the worse this problem is going to get as plants are a crucial element to keeping our air clean and breathable. This news drives home the point that global warming and the climate change it will cause is undoubtedly the defining issue of our time, but we're not doing anything close to enough about it, especially here in America--the second leading CO2 emitting country behind the coal-happy Chinese. This has to become the top issue in American politics and should dominate the 2016 presidential campaign. But to make this happen, we have to continue to raise awareness about what the scientific evidence is telling us every single day.

The Myth of Carbon Pollution
On October 15, 2014 Dr. William Happer, Chairman of the George C. Marshall Institute, discussed “The Myth of Carbon Pollution.” “Carbon pollution” is a propaganda slogan for the campaign against carbon dioxide (CO2). It is not science. Atmospheric CO2 is not a pollutant but is essential for plant growth. Current CO2 levels are far below optimum for most plants, and far below norms of geological history, when CO2 concentrations averaged several times higher than present values. A substantial fraction, about 15%, of current world food production is due to the higher levels of CO2 compared to preindustrial values. Contrary to unambiguous computer predictions, there has been no statistically significant surface warming in at least 15 years. It is now clear that the warming potential of CO2 has been exaggerated by a large amount, and it is unlikely to be much more than 1oC for doubling of CO2. There is not the slightest evidence that more CO2 has caused more extreme weather or accelerated sea level rise. Nor is there the slightest support for the notion that government control of CO2 will “stop climate change.” Many real environmental issues need attention, smog, waste disposal, short-sighted suburban development, adequate clean water, public health, etc. These are being overshadowed by the phony issue of “carbon pollution.” Dr. William Happer is Cyrus Fogg Brackett Professor of Physics (emeritus) at Princeton University, a long-term member of the JASON advisory group, and former director of the Department of Energy’s Office of Science. In addition to being a fellow of the American Physical Society and the American Association for the Advancement of Science, he is a member of the National Academy of Sciences and the recipient of numerous awards, including the Alfred P. Sloan fellowship, the Alexander von Humboldt award, the Herbert P. Broida Prize and the Thomas Alva Edison patent award.
Atmospheric CO2 Concentration at Highest Level in 800,000 Years
Carbon dioxide - the main atmospheric greenhouse gas - reached 410 parts per million in April, for the first time in recorded history. The connection to global warming is undeniable, but emissions have plateaued, which means that we can still reverse this trend, says climate scientist Michael Mann Visit http://therealnews.com for more stories and help support our work by donating at http://therealnews.com/donate.

Climate Change Could Increase Sea Level By 20 Feet
Are we headed for 20 foot sea level increase? Scientists are continuing to sound warnings about rising sea levels.  According to new research, an increase in global temperature by as little as 1.8 to 3.6 degrees Fahrenheit could result in an additional 20-foot increase in sea level. The observations from the past 3 million years indicate that the rise in sea level to that extent has occurred on multiple occasions following small temperature changes on a relative scale. These findings are particularly relevant to modern-day society because the temperature and other environmental conditions are similar now to what they were in the past.  One of the researchers notes, “Modern atmospheric carbon dioxide levels are today equivalent to those about 3 million years ago, when sea level was at least 6 meters higher because the ice sheets were greatly reduced.”  He then remarked, “It takes time for the warming to whittle down the ice sheets, but it doesn’t take forever.” Scientists are also worried that current CO2 levels guarantee an additional rise in sea level, but because atmospheric gases continue to increase, scientists are not sure how high the waters will end up. As a result, coastal areas continue to be vulnerable to more flooding.

Oceans warm up and acidify because of increasing carbon dioxide levels in the atmosphere
Films on Ocean Warming and Acidification "Corrosive Oceans": addresses wide-held concerns about the impact that ocean acidification may have on marine life - today and in the near future. The film explains the relationship between increasing levels of CO2 in the atmosphere and the health of marine organisms - in particular calcifying organisms such as corals and shellfish. Scientific findings on ocean acidification are still predominantly based on experimental research in the laboratory. More data from the field is needed to verify the results of these studies. The film accompanies a group of scientists while they are taking a close look at under water sites in the Mediterranean Sea. These scientists want to find out whether marine life has already been affected by an increase of pH in the waters. Another group of scientists is shown as they are observing marine life close to undersea volcanic vents. Their research gives an indication of how the conditions for marine life may change in the future if the levels of CO2 in the atmosphere continue to increase. - See more at: http://www.eusem.com/main/CE/SIP_C5pub2012

Carbon tax song brings climate change under control
Spread the love to our planet! Lyrics: Hey, do you see a change? Global average temperature has increased. Sea level rises, snow and ice declines. Have no fear, I'm here to help. Take my hand. Close your eyes. Open your mind and absorb the science. As the Sun's rays reach the Earth's surface some are absorbed and re-emitted as heat. Greenhouse gasses like methane and Carbon dioxide absorb and reradiate some of this heat. Increased amounts of greenhouse gasses in the atmosphere mean more heat is trapped warming the earth. Human activities, especially the burning of fossil fuels have increased concentrations of atmospheric carbon dioxide. If emissions continue unchecked then further warming would be expected having serious implications for our society and natural world. It’s not the way it has to be. It’s time for you and me to work together, act together. We can survive through the love. Charge a fee on fossil fuels and return that revenue to households. Carbon tax starts a chain of positive effects. We get to choose our energy sources. Fossil fuel become less desirable and clean energy become more competitive. The dividend creates millions of jobs. World carbon emissions go down. Reduced air pollution saves thousands of lives. And climate change is brought under control. Be vocal, express political will. Demand an action from your government. We must help our elected leaders work together and legislate carbon tax. It’s on us to tell them what we want because when voices call out together, their impact multiplies. Tell your government we want a livable world. Write a letter, call them now Supporting carbon tax is the most important deed. But you can also help with day to day choices. Reduce what you need to throw away. Do more with less. Reuse and recycle. Eat local whole food. Avoid chemical processing. It’s good for your health and reduces your carbon footprint. Prefer drinkable tap water over bottled. Satisfy daily nutrients through knowledgeable shopping. Don't waste energy or people's time. Each human live has a cost, make it count. Spread the idea that we can bring climate change under control. Talk to your friends, family, neighbours. Our planet, Earth is a closed system. If we treat it well we will all flourish.

King Tide Sea Level Rise Flooding Delray Beach Florida
Sept. has become the traditional first month of 3 months of occasional King Tide, Global Warming, Sea Level Rise Flooding in South Florida. Dumping more pollution — carbon dioxide and methane — into the atmosphere is sure to speed up the process that will inundate coastal cities in the decades to come. I took this video at noon in Delray Beach’s historic Marina District and Veteran's Park dock, which are located on the Intracoastal Waterway. The new raised seawall and dock at Veteran's Park appears to have prevented flooding. (The only problem with higher seawalls is they tend to send the water off to flood another location. South Florida is also built on porous limestone, so it's only a matter of time before the water migrates under the seawall.) Oct. usually has the worst flooding. I'll try to take more video then. What's clear from my wet feet is without a radical reduction in carbon emissions, all of FL south of Lake Okeechobee is headed under. Even with reductions, it may be too late. The region's geology -- porous limestone that water can move through -- will make it just about impossible to stop the inundation. Watching developers continue to build within blocks of this slow motion catastrophe is surreal and alarming. But that's Florida. I'm taking these videos so future generations can see how it all began (or ended). Larry Richardson (RichardsonArtPhotographyStore.com and StepByStepChef.com) recorded this video using an iPhone 7

Inland estuaries, fisheries, marine river regions. The marine ecosystems are changing. The sea level is rising too fast, its happening within a human lifetime. A significant amount of change in the sea level. Most of the rise is being caused by the heat in the ocean. Its good for someone to do their own research, read articles by accredited scientists and reputable journalist.People that are knowledgeable about climate, climatology, weather science.Do your own research find books at the library about climatology, meteorology, study gas laws, atmospheric chemistry. Try to understand emission infrared radiation, absorption of long wave. The balance of gases in the atmosphere.

Jim Hansen: Requirement of Negative CO2 Emissions
Young People’s Burden: Requirement of Negative CO2 Emissions, is a publication in Earth System Dynamics Discussion (4 October, 2016), as it is undergoing peer review. We try to make the science transparent to non-scientists. Read full article http://csas.ei.columbia.edu/2016/10/04/young-peoples-burden Publication link http://www.earth-syst-dynam-discuss.net/esd-2016-42 ###Principal Implications### A. Global temperature is already at the level of the Eemian period (130,000 to 115,000 years ago), when sea level was 6-9 meters (20-30 feet) higher than today (Fig. 2). Considering the additional warming “in the pipeline,” due to delayed response of the climate system and the impossibility of instant replacement of fossil fuels, additional temperature rise is inevitable. Earth’s history shows that the lag of sea level change behind global temperature change is 1-4 centuries for natural climate change (Grant et al 2012, 2014)2. It is unlikely that response would be slower to a stronger, more rapid human-made climate forcing; indeed, Hansen et al (2016) infer that continued high fossil fuel emissions could lead to multi-meter sea level rise in 50-150 years. The desire to avoid large ice sheet shrinkage and sea level rise implies a need to get global temperature back into or close to the Holocene range on the time scale of a century or less. B. “Negative CO2 emissions,” i.e., extraction of CO2 from the air is now required, if climate is to be stabilized on the century time scale, as a result of past failure to reduce emissions. If rapid phasedown of fossil fuel emissions begins soon, most of the necessary CO2 extraction can take place via improved agricultural and forestry practices, including reforestation and steps to improve soil fertility and increase its carbon content. In this case, the magnitude and duration of global temperature excursion above the natural range of the current interglacial (Holocene) could be limited and irreversible climate impacts could be minimized. C. Continued high fossil fuel emissions place a burden on young people to undertake massive technological CO2 extraction. Quietly, with minimal objection from the scientific community (Anderson, 2015, is a courageous exception), the assumption that young people will somehow figure out a way to undo the deeds of their forebears, has crept into and spread like a cancer through UN climate scenarios. Proposed methods of extraction such as bioenergy with carbon capture and storage (BECCS) or air capture of CO2 imply minimal estimated costs of 104-570 trillion dollars this century, with large risks and uncertain feasibility. Continued high fossil fuel emissions unarguably sentences young people to either a massive, possibly implausible cleanup or growing deleterious climate impacts or both, scenarios that should provide incentive and obligation for governments to alter energy policies without further delay.

Oceans are absorbing more heat than previously estimated

RESTRICTIONS: Broadcast: NO USE JAPAN, NO USE TAIWAN Digital: NO USE JAPAN, NO USE TAIWAN The world's oceans have absorbed considerably more heat than previously estimated, according to a new study. The results, published in the journal Nature on Wednesday, found that seas around the globe may be absorbing up to 60 percent more heat since the 1990s than earlier estimates calculated, according to Scientific American. Researchers calculated the oceans have absorbed around 13 zettajoules of heat energy every year between 1991 and 2016, CNN reports. The findings suggest the earth is more sensitive to greenhouse gas emissions than previously thought. Rather than relying on direct ocean measurements, the researchers looked at the amount of oxygen and carbon dioxide in the atmosphere since 1991. As oceans warm up, their ability to absorb oxygen and carbon dioxide decreases, thus more of those gases remain in the air. By measuring the changes in atmospheric oxygen and carbon dioxide levels, while also controlling for other factors such as human greenhouse gas emissions, the team was able to estimate how much heat the oceans have absorbed over the past few decades. Warmer oceans could potentially lead to sea levels rising faster than forecasted, dying off of coral reefs, increasingly powerful storms, faster rates of melting sea ice and affecting ocean currents, CNN reports.

The Past Half-Century of Sea Level Rise
In his testimony before the U.S. House of Representatives Select Committee on Energy Independence and Global Warming, NASAs James Hansen stated there is increasing realization that sea level rise this century may be measured in meters if we follow business-as-usual fossil fuel emissions. Agreeing with Hansen, many people have been quick to jump on the CO2-induced global warming/rising sea level bandwagon. But how close to reality are the projections of a future sea level rise that is measured in meters?

Alert: High Levels of Carbon Dioxide Causing Malnutrition
The concentration of carbon dioxide (CO2) in the atmosphere has hit a new high, the UN said on Monday, warning that drastic action is needed to achieve targets set by the Paris climate agreement. "Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016," the World Meteorological Organisation said. "Globally averaged concentrations of CO2 reached 403.3 parts per million in 2016, up from 400.00 ppm in 2015 because of a combination of human activities and a strong El Nino event," it said. The Greenhouse Gas Bulletin, the UN weather agency's annual flagship report, tracks the continent of dangerous gasses in the atmosphere in the post-industrial era (since 1750). The report also said that the last time Earth experienced similar CO2 concentration rates was three to five million years ago when the sea level was up to 20 metres higher than now.

Lord Christopher Monckton On The Question of The Sea Level Rising
This was filmed during the question time after Lord Monckton's eloquent and informative speech about climate change swindling in Whangarei, New Zealand on August the 6th, 2011. Venue: Northland Events Centre, Okara Drive, Whangarei Time: 2.00pm Hosted by: Farmers of New Zealand One member of the audience asked about the matter of the sea levels rising, and Lord Monckton referred to the work of Dr Morner. As he indicates, the idea that sea levels are rising is merely a hoax and a fraud, (which is designed to empower governments and frighten the public into paying taxes to greedy globalist (New World Order) bankers, amongst others).

Global Warming and its Evidence | Hindi
Human impact on the global climate increased sharply after the Industrial Revolution and average temperatures began to rise.This was largely caused by carbon dioxide emissions from the burning of fossil fuels such as coal, oil and natural gas. Carbon dioxide is a greenhouse gas. It absorbs invisible heat radiation from the Earth, emitting much of it back down. Consequently, the Earth's surface is heated by both visible sunlight and infrared radiation in what is called the greenhouse effect, which leads to global warming. Satellites have measured changes in sea level by a few centimetres, in the recent years. In the first decade of 21st century, storms became more frequent and violent. More Hurricanes in the Caribbean, typhoons in the China Seas and heavier monsoons in India. Glaciers in mountains around the world, are melting back. Europe's glaciers are thought to have lost around a quarter of their mass, in the first decade of 21st century. Almost all of Alaska's 2000 glaciers, are said to disappear by the end of 21st century. It is high time that we accept the fact that global warming is already happening and join hands to save the world for our future generations.

Greenland meltwater making sea levels rise more rapidly - TomoNews
GREENLAND — Ice melting from Greenland's ice sheets may cause a rapid increase in sea levels. It's no surprise that humankind is running against the climate-change clock, but dire changes may come sooner than expected. Ice sheets in Greenland are melting at an unprecedented rate. The most comprehensive study of the subject ever has found levels of meltwater from the Arctic island are 50 percent higher than during pre-industrial levels. According to a paper published in the journal Nature, researchers extracted ice core data in order to examine rates of surface melt and run-off in Greenland. Ice cores are long tubes of ice and snow samples drilled from an ice-sheet or glacier. Each layer contains key climate information including changes in atmospheric carbon dioxide levels, and climate stability. The data examined goes back 339 years. The first signs of meltwater date back to the mid-1800s, coinciding with the beginning of the industrial revolution." Data from the research revealed Greenland's ice sheets are melting more quickly than they ever have in the last 350 years. According to data from the UN Intergovernmental Panel on Climate Change, meltwater from Greenland contributes to roughly 20 percent of the world's sea-level rise. If all the ice in Greenland melted, sea levels would rise by seven meters. The National Oceanic and Atmospheric Administration reports that global sea levels are rising at an increasing rate. At the moment, sea levels are rising at a rate of 0.32 centimeters per year.

Global warming, CO2, and sea level rise: Two Perspectives
Global warming or climate change to be less specific, is a hot topic today with many points of view. Science is pretty convinced now that global warming is occurring. Sea level is rising. CO2 levels are rising. Global temperature is rising. Despite the peculiar idea that climate change is a hoax, there remain questions about why global warming is occurring. Is CO2 the cause and if so is the cause human generated CO2. How much warmer will it get? How high will the sea rise? What will be the result of sea level rising and warmer climates? How will the natural environment be able to cope or not? This debate is the subject of my two perspectives. The video used principles of split-screen and green screen to achieve the result of me debating myself. The main question is not about whether global warming is happening, but instead what shoudl we do about it?

Mass Extinctions in Earth's History (2014)
Scientist Peter Ward explains the interconnections of rising carbon dioxide levels and flood basalt, and how it leads to anoxic oceans (with Hydrogen sulfide). Ward explains how today's CO2 levels will result in sea level rise with disrupting implications for crops and how deglaciation will ultimately result in a stagnant ocean, hinting at past extinction events. Warming is most pronounced at the poles, hence the amplification there. Professor Kevin Schaefer (NSIDC), Ben Abbott (University of Alaska) and Dr. Charles Miller (NASA/JPL) explain how Arctic heating is thawing the permafrost.

Climate change: Ice sheets melting cause fastest sea level rise in 2,800 years - TomoNews
NEW BRUNSWICK, NEW JERSEY — A new study shows that sea level is rising at a speed that is faster than the previous 27 centuries. Sea level rose at a rate of 1.4 millimeters per year between 1900 and 2000 while the current rate is 3.4 millimeters per year, according to data provided by NASA. The study, led by Robert Kopp, a professor of earth and planetary sciences at Rutgers University, shows that although it is impossible to slow the rate of sea level rise to what it was in the 20th century, a low carbon dioxide emissions scenario would make it more likely than a high carbon dioxide emission scenario. The study, published on Monday in the Proceedings of the National Academy of Sciences, also points out that the major factor in future sea level rises is the melting of the huge ice sheets of Greenland and Antarctica. The study was based on earlier sea level rises at 24 locations around the world, as well as recent measurements from 66 global tide gauges. ----------------------------------------­--------------------- Welcome to TomoUSA, where we animate the most entertaining news from ‘MURRICA.
