Climate Change’s Fingerprints Came Early, a Thought Experiment Reveals

Scientific American

Second, we assumed that over the period 1860 to 2024, the model simulations used reliable estimates of human-caused changes in greenhouse gases, particulate pollution and land use, as well as accurate estimates of natural changes in external factors like volcanic activity and the sun’s energy output. The consequence?

The Energy Secretary Pushes Pseudoscience

Legal Planet

Late last month, Energy Secretary Chris Wright and the Energy Department rushed a report called “Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” by 5 authors handpicked by Wright (a former fossil fuel executive) for their contrarian views on climate science. It is a hoax.”

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

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.

AR6 of the best

Real Climate

As climate scientists 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!) 1, SPM, AR5.

Antarctic extreme events: ‘All-time records are being shattered not from decades ago, but from the last few years and months’

Frontiers

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.

Using Clouds to Fight Climate Change

HumanNature

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.

Science denial is still an issue ahead of COP28

Real Climate

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.” It’s not hard to understand. Gray areas show lack of data.
