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.
It turns out, for example, that climate-change researchers fly more frequently than scientists in other fields. Change 65 102184 ), climatescientists jet off two to three times a year on average, whereas other researchers get on planes just twice during that time. But other scientists also fly a lot.
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.
Altering cloud properties influences Earth’s climate On sunny days, it’s clear that clouds leave shadows on the landscape. Climatescientists are interested in clouds for exactly this reason- clouds reflect sunlight, which has a cooling effect on surface temperatures. Cirrus clouds formed this way have many, small ice crystals.
With announcements from the Intergovernmental Panel on Climate Change (IPCC) growing bleaker by the year, climate change activism has become increasingly bold and desperate.

Manabe’s Climate Modeling. Fortunately, Manabe recently wrote a retrospective on his early work in response to receiving the Crafoord prize in 2018. In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climatescientists. That paper ( Manabe et al., Gnanadesikan et al.,
A 2017 study led by geographer Camilo Mora from the University of Hawaii found that around 30% of people around the world are already exposed to climatic conditions above this deadly threshold for at least 20 days a year ( Nature Climate Change 7 501 ). Limiting warming to 2?°C C rise we’re heading towards .
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.
In June 2018, DEP finalized an Air Quality General Permit to reduce methane emissions from new unconventional oil and gas operations. Sharp cuts in methane emissions are among the most critical actions the United States can take in the short term to slow the rate of climate change. Read more here. [In Read more here.]
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. It has also inspired landmark decisions in climate protection on a global scale.
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.
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. 15-1363 et al.
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. 2018) ; Tartu et al. 2018) ; Aars et al.

Environmental Protection Agency’s (EPA’s) 2018 rule in which EPA decided to expand the D.C. EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. EPA’s 2018 rule also suspended the prohibition for companies currently using ozone-depleting substances.
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
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.

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). City of New York v.
