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.” Gray areas show lack of data.

A Nobel pursuit

In this, he is in violent agreement with Isaac Held, his colleague at GFDL, and indeed most climate scientists. Manabe’s subsequent work led to the development of the GFDL GCM, initially just including the atmosphere, but eventually with an ocean, and then the transient results shown in Manabe and Stouffer (1993).

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.

A science-based move to climate change adaptation

Real Climate

It’s also urgent because the oceans act like a flywheel, making sure that cuts in emission of greenhouse gases will have a lagged effect on global warming. However, I would argue that the climate research community has not had a visible presence during any of these meetings. Nevertheless, it’s a key part for climate adaptation.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

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 ). Furthermore, the volume of the oceans increases from the melting of land ice.

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.

Climate Change Is Intensifying the Water Cycle, New IPCC Report Finds

Circle of Blue

The Intergovernmental Panel on Climate Change, a group of the world’s leading climate scientists, released its sixth climate assessment on Monday. The 1,300-page paper is the most comprehensive, up-to-date report yet on the physical science of climate change, synthesizing the findings of thousands of recent publications.
