The world needs "major institutional and technological change" to have a real chance at keeping temperature rise to 2 Celsius degrees. The third and final IPCC report on climate mitigation, released on April 13, is a strong call to action. "The high-speed mitigation train would need to leave the station soon and all of global society will have to get on board," said Rajendra Pachauri, chairman of the IPCC.
The WGIII report comes on the heels of the WGII report on climate impacts and adaptation, published March 31, which emphasizes the high cost to society of expected impacts of climate change.
