It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. The Keeling curve, highlighted with the release of important climate reports and climate summits.
There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climatescientists. Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993).
It is 33 years now since the IPCC in its first report in 1990 concluded that it is “certain” that greenhouse gas emissions from human activities “will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.” Gray areas show lack of data.
The Intergovernmental Panel on Climate Change, a group of the world’s leading climatescientists, released its sixth climate assessment on Monday. The 1,300-page paper is the most comprehensive, up-to-date report yet on the physical science of climate change, synthesizing the findings of thousands of recent publications.
It’s also urgent because the oceans act like a flywheel, making sure that cuts in emission of greenhouse gases will have a lagged effect on global warming. However, I would argue that the climate research community has not had a visible presence during any of these meetings. Nevertheless, it’s a key part for climate adaptation.
A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). Furthermore, the volume of the oceans increases from the melting of land ice.
As climatescientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) Figure SPM 8. 1, SPM, AR5.
Writing as part of Frontiers’ guest editorials series, the study’s lead author – Prof Martin Siegert, deputy vice chancellor of the University of Exeter (Cornwall) – discusses how without there being a rapid shift to net-zero greenhouse gas emissions by 2050, the Antarctic environment will experience ever more drastic changes.
The El Niño–Southern Oscillation ( ENSO ) is one of the most significant, but variable, climate patterns in the world. This tropical Pacific Ocean phenomenon affects weather in South America, Australia, Asia, and beyond. Researchers are also studying how ENSO will be affected by climate change.
An area of high pressure above the Pacific Ocean was driven eastwards through the jet stream by a “Rossby wave” – a planetary-scale fluctuation arising from the Coriolis force. The Rossby wave eventually “broke”, dumping its energy – like an ocean wave hitting the shore – to create an area of high pressure locked over western Canada and US.
For climatescientists, the war in Ukraine came at the worst possible time as the media attention they would have hoped for surrounding the release of the latest Intergovernmental Panel on Climate Change (IPCC) report was urgently diverted to the breaking news story of Russia invading Ukraine. By Anders Lorenzen.
By Claire Hemlett An increasing number of food brands are turning to climate labels to boost sales. In the face of research that meat and milk are high in greenhouse gas emissions , companies are angling for new ways to reach eco-conscious consumers. Photo credit: Sentient Media. Our emissions are just too high at this point.
According to the respected International Energy Agency’s new report, global greenhouse gases emissions from energy remained flat in 2016 while the global economy grew by 3.1 Our ecosystems’ ability to deal with carbon and absorb it (notably our oceans) may also be decreasing… So what should Mankind do ?
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
This spring, Texas A&M climatescientists Andrew Dessler and Jangho Lee told the Associated Press that last year’s real national annual heat death toll may be 11,000, nearly five times higher than the 2,300 cited by the government. Even better, of course, would be a serious drive toward net-zero greenhouse gas emissions.
Some of the highest risks can be found in the candidates’ home states: the ocean off of Florida has hit 98 degrees— hot tub temp s! Among mid-Atlantic states, New Jersey is ground zero for climate change. We should expect to hear more, as climate impacts are only going to get worse.
Circuit Court of Appeals granted motions seeking to dismiss as moot the proceedings challenging the Obama administration’s Clean Power Plan, which established emission guidelines for greenhouse gases from existing power plants. Court Dismissed Counterclaims in ClimateScientist’s Defamation Lawsuit.
Plaintiffs aim to hold the federal government accountable for worsening the dangers of climate change through increased reliance on fossil fuels and for breach of its fiduciary obligation to protect the atmosphere and oceans under the public trust doctrine. Public Nuisance Cases. over a dozen.
establishing that heat-trapping emissions (or greenhouse gas emissions) are air pollutants covered by the Clean Air Act. The 2007 case was brought by petitioners (which included several state attorney generals and NGOs, including the Union of Concerned Scientists) in the context of greenhouse gas emissions from new motor vehicles.
In videos and Congressional testimony , Wright portrays himself as a truth teller, while falsely claiming that climatescientists and renewable energy advocates are deceptive. Advances in attribution science also show that climate change is contributing to worsening some types of extreme weather. Carbon pollution is pollution.
The project is controversial due to its contribution to greenhouse gas (GHG) emissions and its location on the North Slope of Alaska, which happens to be the largest undisturbed track of public land in the U.S. and an area that is highly sensitive to climate change.
establishing that heat-trapping emissions (or greenhouse gas emissions) are air pollutants covered by the Clean Air Act. The 2007 case was brought by petitioners (which included several state attorney generals and NGOs, including the Union of Concerned Scientists) in the context of greenhouse gas emissions from new motor vehicles.
The court stated: “Plaintiffs’ claims for public nuisance, though pled as state-law claims, depend on a global complex of geophysical cause and effect involving all nations of the planet (and the oceans and atmosphere). Arizona Court Ordered Production of ClimateScientists’ Emails Under Arizona’s Public Records Law.
EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. In particular, the court found that conclusion that greenhouse gas emissions constituted a significant impact was not clearly erroneous. Circuit’s partial vacatur in Mexichem Fluor, Inc. State , No.
This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. It’s the third chapter in the IPCC’s mammoth sixth assessment report, part of a series of studies that summarize the state of climate science and the planet released roughly every seven years. The IPCC said 1.5
One, greenhouse gas emissions will be significantly reduced, as will other forms of pollution that harm Pennsylvanians' health and drive up healthcare costs and absenteeism. Let us remember, we're not here to debate the issue of climate change. It needs to be an informed decision with equal input from climatescientists and economists.
The Sea Grant Knauss Fellowship provides a unique educational and professional experience to graduate students who have an interest in ocean, coastal and Great Lakes resources and in the national policy decisions affecting those resources. More News: Climatescientists grapple with wildfire disaster in their backyard – Axios.
Next week, the House is expected to consider another six spending bills, including a bill funding the National Science Foundation and the National Oceanic and Atmospheric Administration. Sarah Kapnick as the agency’s chief scientist. in atmospheric and oceanic science from the University of California, Los Angeles. 13, 2022).
The SCC is a metric that seeks to capture all of the costs that emitting a ton of carbon dioxide (or equivalent amounts of other greenhouse gases such as methane) imposes on society by contributing to climate change over the hundreds of years it remains in the atmosphere. 4:21-cv-00287-SPM (E.D. March 8, 2021).]] 2019); Birckhead v.
Assessing cumulative impacts means agencies would analyze the ramifications for climate change by weighing how many greenhouse gases projects and decisions unleash at the end of the value chain. During her confirmation hearing, Medina pledged to prioritize addressing biodiversity loss, ocean protection and space policy.
