Just 6 countries: The United States, Colombia, South Africa, Russia, Indonesia and Australia. If somehow we could sprinkle (perhaps shake) a little common sense, the rest of the world would be deprived of imports of the most polluting and CO2-intensive fossil fuel … Continue reading →

Geoengineering can save Greenland, model suggests

We recently witnessed a new Greenland melting record. And according to a new paleoclimate comparison by James Hansen we could be in for meters of sea level rise within this century, due to expected non-linearity of the melting process.

Hansen: paleoclimate shows 2 degrees climate target leads to multiple meters of SLR

Comparing previous interglacial periods, like the Eemian, to the present geological epoch, the Holocene, shows slight average temperature rises are strongly magnified around the poles. Even under the 450 Scenario 21st century sea level rise could reach multiple meters. “Current … Continue reading →

Communicating climate science is defined activism

Renowned climatologist and Head of NASA’s Goddard Institute for Space Studies James Hansen recently wrote a short essay, explaining the path from developing scientific understanding, to improving civil implementation of that knowledge – or how he became ‘an activist’:
