A new international study, published in Science Advances, fully accounts for what is driving the world's rising oceans over six decades.

Leipzig. Aerosols and clouds play a key role in the Earth’s climate budget. However, the extent to which they reflect solar energy depends heavily on how much water the particles can absorb. This so-called hygroscopicity has so far been represented in a simplified manner in climate models. An international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has now demonstrated through a global study that the models are not precise enough, particularly in urban regions. In chemically complex and polluted regions such as Delhi or Cairo, there is likely to be greater hygroscopic growth and higher water uptake, which could partly explain the observed regional cooling trends or the slower warming on the Asian and African continents, the researchers write in the journal Communications Earth & Environment, published by the Nature Publishing Group.

Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead time to prepare for inclement conditions.
