Stefan Rahmstorf: The critical threshold, the “tipping point” in West Antarctica has now passed

Recently the ClimateState staff, interviewed Stefan Rahmstorf, Head of Earth System Analysis, at the Potsdam Institute for Climate Impact Research (PIK). Robert Bristow: To get CO2 emissions under control – do you think some form of geoengineering (i.e CO2 scrubbing) will be desirable? Stefan Rahmstorf: The term geoengineering or climate engineering, encompasses a wide range…

EU could afford to lead international climate action

Late-comers face a clear trade-off between lower short term costs and higher transitional challenges PIK (Potsdam Institute for Climate Impact Research) 03/19/2014 (Translation: Artikel in Deutsch) – This week, the heads of the EU member states will meet in Brussels to discuss the adoption of a 40 percent greenhouse gas reduction target for 2030. Despite…

Heat Waves to Become Much More Frequent and Severe

Science Daily Aug. 15, 2013 — Climate change is set to trigger more frequent and severe heat waves in the next 30 years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown. Extreme heat waves such as those that hit the US in 2012 and Australia…

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

By PIK: 07/15/2013 – Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of…

Ups-and-downs of Indian monsoon rainfall likely to increase under warming

PIK June 20, 2013: Day-to-day rainfall in India might become much more variable due to climate change – potentially putting millions of poor farmers and the country’s agricultural productivity at risk. The Indian monsoon is a complex system which is likely to change under future global warming. While it is in the very nature of…

Humid air and the Jet Stream help to fuel more intense thunderstorms/tornadoes

“The fuel for the more intense storms would be the predicted warming of the Earth caused by the burning of fossil fuels that release greenhouse gases.” A combination of a slower Jet Stream (see video for explanation and study) and a more humid atmosphere increase the likelihood for a more intense thunderstorm environment. This conclusion…
