Even the Paris Commitments of 80 percent emissions reductions by 2050 allow warming to triple by 2050 and quintuple by 2100.  We (the royal we) have great challenges as climate reform decision makers.

Climate change projected by the IPCC 2013 report under the business as usual scenario (RCP8.5) projects climate change in the next 100 years to be as big as the Paleocene/Eocene Thermal Maximum extinction event 56 million years ago. Changes today however are happening 100 times faster than the PETM. The PETM was likely a methane…

Ecological consequences of a warming planet – Earth’s Caribou population has collapsed – Foreshadowing ecological trends across the rest of the planet

By Extinction events

The International Polar Year resulted in this study by a team of 25 Arctic researchers. Seven degrees of warming in some parts of the Arctic have changed more than just the average temperature. The Arctic biosphere is collapsing. Arctic sea ice is projected to disappear like it has not done in 14 million years (here)….
