Gaming carbon

"Ashwood Farms" emission reduction project

Later this year Environment Minister Hunt will be heading off to Paris for the 21st annual United Nations climate change conference. Hunt’s brief will be clear: obfuscate as best you can to minimise domestic damage, while delivering essentially nothing. Harsh? I offer as evidence his centrepiece policy, “Direct Action”… . . . → Read More: Gaming carbon

Updating the geological temperature graph

Geological temperature history of Earth

A weakness of my combined geological temperature record graph has always been the Royer / Veizer temperatures for the Cretaceous (66-145 My) and earlier. Unfortunately some people don’t read caveats and just take the thing as gospel, even citing actual numerical values from it
