Climate sensitivity is hot these days. That is because ‘the lukewarmers’* have tried to suggest it is overestimated – and now real climate scientists are publishing studies showing the opposite: climate sensitivity may be underestimated. Revising equilibrium climate sensitivity upwards, … Continue reading →
Yesterday we took a look at what we have been doing over the past 40 years. Now we take a look at what we will be doing over the rest of the 21st century. It’s a real shocker to look … Continue reading →
The second part of the new IPCC report, about the impacts of climate change, has been released on Monday. Across the globe dutiful journalists filled the headlines of their newspapers – and as they presume most of their readers are … Continue reading →
Clouds have a profound effect on the climate, but we know surprisingly little about how they form. Erika Sundén has studied how extremely small cloud particles can dispose of excess energy. This knowledge is necessary to understand processes in the atmosphere that affect global climate change.
The most-quoted climate sensitivity range (IPCC 4AR) suggests a median temperature response to a doubling of the atmospheric CO2 concentration of 3 degrees Celsius – and a 66 percent probability range warming under CO2-doubling will be somewhere between 1.5 and … Continue reading →
Yes, indeed, we’re a couple of days late bringing you the news. But this could be an important update to our Arctic melting coverage. It’s feedback-driven (after all), American and French researchers say.
