A hand holds a wooden thermometer with a red mercury column, displaying temperatures in degrees Celsius and Fahrenheit. The red column indicates approximately 40 °C (100 °F). In the blurred background, a building is visible under a blue sky, suggesting a hot outdoor temperature.

Climate Models With High Resolution in the Ocean Can Better Represent European Heat Waves

The North Atlantic significantly influences the weather in Europe. For instance, a cold spell in the subpolar North Atlantic can lead to a heat wave…

Closely packed treetops create an undulating landscape. The shadows of clouds can be seen on the green.

Deforestation Leads to More Extreme Weather Events in the Amazon Region

If the Amazon rainforest were completely cleared, extreme precipitation, heat stress, and high wind speeds would occur more frequently. This is the…

Earth’s Climate Sensitivity

How much will the Earth warm if the amount of carbon dioxide in the atmosphere doubles? The answer to this seemingly simple question is highly…

Aerial view of a massive glacier in a snow-covered mountain landscape. The glacier flows through the mountains and shows characteristic features such as meltwater streams and crevasses. The surrounding mountains are partially rocky and snow-covered, while the sun casts long shadows and highlights the texture of the ice.

Stability of the Greenland Ice Sheet: When the Ice Loss Becomes Irreversible

In a pre-industrial climate, the Greenland Ice Sheet can take on four different steady states, as demonstrated by simulations using a fully-coupled…
