Arguments that the climate is relatively insensitive to the increased greenhouse effect have become the last best chance for climate contrarians, but a new study from Texas A&M University hammers a big nail in the coffin of that argument. With overwhelming evidence that humans are the main cause of global warming, and with arguments that modest warming is beneficial falling apart, those who oppose climate solutions are forced to put their eggs in the ‘low climate sensitivity‘ basket. If the Earth’s climate is less sensitive to the increased greenhouse effect than most of the available evidence indicates, then perhaps there’s not quite as much urgency to tackle the threat of global warming, they argue.
