The bulk of recent research still suggests climate sensitivity values close to the most established numbers, numbers that have been around for many years. (bitsofscience.org)
If the 3 C climate sensitivity value were to prove correct, then that would imply global warming of between 1.5 and 3 degrees Celsius. (hubpages.com)
As these figures show, estimates from both models and observational data consistently find that the most likely climate sensitivity value is approximately 3 °C for a doubling of CO2. (skepticalscience.com)
