Similarly, there have been increases in other greenhouse gases , which Gavin nicely describes in his recent post Operationalizing Climate Science. In a nutshell, they are responsible for climate change, mainly due to an increased greenhouse effect.
Climatescientists are inordinately excited by the release of a new IPCC report (truth be told, that’s a bit odd – It’s a bit like bringing your end-of-(seven)-year project home and waiting anxiously to see how well it will be received). AR6 of the Best.
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.
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.
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 ). The global sealevel acts like the mercury in a thermometer because warmer water expands.
Meltwater from Greenland’s ice sheets have caused about a quarter of the rise in the world’s sealevels. This week, Circle of Blue looks at a major new climate report, which finds that a warming planet is accelerating the water cycle. degrees, the goal established in the Paris Climate Agreement.
WMO Secretary-General Peterri Taalas laid the facts bare, stating: “Greenhouse gas levels are record high. Sealevel rise is record high. Antarctic sea ice record low.” degrees C ceiling because, for that to happen, the level of warming would need to be sustained for longer. degrees C is bad enough.
“A code red for humanity” is how António Guterres, the United Nations’ secretary general, described the latest report from the Intergovernmental Panel on Climate Change , which summarizes our current scientific understanding of the Earth’s climate and the potential impact that changes to it could have on the planet.
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.
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.
We should expect to hear more, as climate impacts are only going to get worse. As a climatescientist recently said on CNN, “Until we stop pumping greenhouse gases into the atmosphere we have no idea what the future looks like.”
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. But, said the judge, “this is a securities fraud case, not a climate change case.”.
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 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.

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 that the issue arose “because a necessary and critical element of the hydrological damage caused by defendants’ alleged conduct is the rising sealevel along the Pacific coast and in the San Francisco Bay, both of which are navigable waters of the United States.” North Coast Rivers Alliance v. 34-2015-80002005 (Cal.
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.
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 plaintiffs—identified as environmentalists, environmental groups, natural resource conservation groups, and cattle ranchers—alleged, among other things, that the immigration actions resulted in increased greenhouse gas emissions. Energy Policy Advocates v. Mayor & City Council of Baltimore , No. July 15, 2021). Oatly Group AB , No.
NOAA: The Biden administration named Dr. Sarah Kapnick as the agency’s chief scientist. Kapnick most recently worked as a senior climatescientist and sustainability strategist for asset and wealth management at J.P. Starting July 1, Sea-Level Rise Studies Required for Florida Gov’t Coastal Structures – Insurance Journal.
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).]]
A few general resources: Sidelining Science Since Day One: How the Trump administration has harmed public health and safety in its first six months by The Union of Concerned Scientists I Heart ClimateScientists. . pulling out of the Paris climate deal may make China great again. And now the full list: . 2017.06.01.
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.
