Carbon dioxide’s climate effects confirmed: temperatures followed rising CO2 levels during last deglaciation

There has been much speculation about what exactly caused the end of the last ice age 10,000 years ago. Some say the Earth’s orbital changes were the cause, others say it was an increase in atmospheric CO2. But although a … Continue reading →

Some corals resistant to ocean acidification

With atmospheric and oceanic CO2 levels rising and the consequent acidification of the oceans, marine life has to adapt rapidly if they want to stay around. Especially calcium carbonate skeleton building organisms are affected by the rapidly dwindling seawater pH … Continue reading →

‘No, climate sensitivity is not smaller, it is higher than we thought’ – because organic aerosol feedbacks mask warming

Says an international research group led by Gothenburg University. It serves to show individual climate sensitivity studies are never conclusive but add up bits of fresh understanding to an already enormous pile of data and knowledge.

Marine biodiversity driven by environmental changes

Our most important source for knowledge about past life is the fossil record. But how exact is it in telling us about the history of life? According to a new study in Science the evolution of marine life over the … Continue reading →
