Threefold increase of dust led to -40 ppm CO2 Antarctic iron fertilisation during Pleistocene

An international team of researchers today in Nature explain the importance of dust storms for climate variability, not just for the radiative balance, but also for the Earth’s carbon cycle. For geoengineering minds: iron fertilisation at least seems to have … Continue reading →

Biosphere’s influence on cloud formation larger than previously thought

Clouds can have a large impact on global climate. Depending on conditions they can either trap or reflect the sun’s heat. Scientists at CERN have now determined that organic vapours released by Earth’s organisms play a far more significant role … Continue reading →

Tropical forest CO2 fertilisation: self-mitigation of emissions possibly around 15 percent

In which case increased tropical forest density would sort of average out emissions of tropical deforestation. [Is it just us or do you share the feeling something is uncomfortably unsustainable about that comparison?] A couple of days ago we reported … Continue reading →

The wildfire climate feedback, tundra´s case: megatonnes of extra CO2

Globally 2007 was one of the hottest years on record. In the Arctic it led to the thus far smallest sea ice extent. But that’s not the only thing unprecedented that happened in the far north. For the first time … Continue reading →
