Sea level rise is a big deal Use, abuse and misuse of the CMIP6 ensemble The radiative forcing bar chart has gone full circle Droughts and floods are complicated Don’t mention the hiatus. Sea Level Rise: The previous IPCC reports, notably AR4 and AR5 (to a lesser extent) , have had a hard time dealing with SLR.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans. The global mean sea level has increased by 20 cm from 1901 to 2018, and the rate of increase has accelerated and is now about 3.7 mm increase every year.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

I had the opportunity to explore and use this dataset as a co-author on a peer reviewed wildfire attribution study last year, which found that nearly 40% of the total area burned in forests in western North America since 1986 is attributable to emissions traced to the top 88 carbon producers.

Since that 2014 study, which laid the foundation of what is called climate source attribution science , UCS scientists have collaborated with Heede on two other studies that pinpointed the major carbon producers’ culpability for specific climate change-related trends. percent of total emissions. percent of total emissions.
