IPCC graph of the day: bridging a gap of >600 ppm – immediate clamp down on fossil fuels required

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

Permian-Triassic climate lesson: Don’t even try to adapt to a mass extinction, mitigate – a single plague can kill a planet!

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

New Insights Into Cloud Formation

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.

Good news? According to paleo research median CO2 climate sensitivity could be 0.7 degrees lower

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

Climate models underestimate Arctic melting – ice dynamics feedback not taken into account

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.

IPCC AR5 looks into geoengineering science

Next week, Monday till Wednesday, climate experts from IPCC WGI, II & III will get together in Lima to discuss a possible inclusion of geoengineering measures in climate policy. Although intended for participants only, the programme, including abstracts of keynote … Continue reading
