Comparison with observations shows cloud simulations improving

Climate projections, such as those used by the Intergovernmental Panel on Climate Change, rely on models that simulate physical properties that affect climate, including clouds and water vapor content. Clouds and water vapor ...

Ice-age climate clues unearthed

How cold did Earth get during the last ice age? The truth may lie deep beneath lakes and could help predict how the planet will warm again.Sediments in lake beds hold chemical records of ages past, among them the concurrent ...

Physicists decipher social cohesion issues

Migrations happen for a reason, not randomly. A new study, based on computer simulation, attempts to explain the effect of so-called directional migration – migration for a reason – on cooperative behaviours and social ...
