New study reveals local drivers of amplified Arctic warming

The Artic experienced an extreme heat wave during February 2018. The temperature at the North Pole soared to the melting point of ice, which is about 30 to 35 degrees (17-19 Celsius) above normal. Recent studies indicate ...

Drought increases CO2 concentration in the air

ETH researchers have shown that during drier years, the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon. This global effect is so strong that it must be integrated ...

Formation of coal almost turned our planet into a snowball

While burning coal today causes Earth to overheat, about 300 million years ago, the formation of coal brought the planet close to global glaciation. For the first time, scientists show the massive effect in a study to be ...
