BBC News - CO2 climate sensitivity 'overestimated'

BBC News - CO2 climate sensitivity 'overestimated': The authors stress the results do not mean threat from human-induced climate change should be treated any less seriously, explained palaeoclimatologist Antoni Rosell-Mele from the Autonomous University of Barcelona, who is a member of the team that came up with the new estimates.
But it does mean that to induce large-scale warming of the planet, leading to widespread catastrophic consequences, we would have to increase CO2 more than we are going to do in the near future, he said.
"But we don't want that to happen at any time, right?"
"At least, given that no one is doing very much around the planet [about] mitigating CO2 emissions, we have a bit more time," he remarked.
