From Research to Action: The Growing Impact of Attribution Science

Union of Concerned Scientists

By comparing these two data sets, scientists can determine the probability that human activities are responsible for observed changes in temperature, precipitation patterns, sea level rise, and other climate change indicators. A study of a 2018 South African drought found that climate change made it three times more likely.

Another Historic Climate Court Ruling in the Netherlands

Legal Planet

What’s most remarkable is that the decision calls for a 45% reduction of carbon dioxide (CO 2 ) emissions–of not only its own but also those of its customers–within less than a decade. To determine what this requires, the court turns to the 2018 Special Report on 1.5°C First, who can stand as a plaintiff?

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.

Arctic Futures: White Shield or Blue Economy

Legal Planet

Total loss of the Greenland ice sheet, for example, would raise sea levels globally by more than 20 feet. The paper sets out an agenda for research into ways to limit glacial ice-sheet deterioration and associated sea level rise. Open Arctic sea lanes dramatically shorten shipping times from China to Europe.

The AMOC: tipping this century, or not?

Real Climate

So the Ditlevsens used sea surface temperatures (SST) in a region between the tip of Greenland and Britain as an indicator, based on Caesar et al. 2018 ( PDF ; I’m a coauthor on that paper). We have direct AMOC measurements only since 2004, a time span too short for this type of study. The reanalysis data show the latter is the case.

The Fifth National Climate Assessment: Implications for Agriculture

National Sustainable Agriculture Coalition (NSAC)

As those paying attention to agriculture know, climate impacts have become increasingly apparent since the last assessment was published in 2018. Sea level rise is also important in the region, causing saltwater intrusion and salinization. Other risks include increasing tropical cyclones and sea level rise.
