From Fieldwork to the Literature: ORCESTRA Overview Paper Published

In 2024, the ORCESTRA field campaign examined cloud organization in the tropical Atlantic using three research aircraft, two ground stations, a…

View from an airplane window over a vast landscape dotted with numerous lakes and rivers. In the foreground, the red wing of the aircraft is visible, while below lies a green, water-rich region with many dark lakes and a wide river. The scene depicts a typical arctic or subarctic landscape.

How can Thermokarst Lakes be Incorporated into Climate Models?

Thermokarst lakes are numerous and dynamic and play a significant role in the Arctic hydrology and climate. Until now, however, there has been no way…

Researchers Identify Three Phases of Climate Change in the Tropical Pacific

Experiments with a climate model reveal that the tropical Pacific responds to increased atmospheric carbon dioxide levels in three distinct phases.…

Two sediment cores attached to a folding rule. Some darker layers stand out. Below the sediment cores is a white board labeled "Bottom" (left) and "Top" (right) as well as "M51/3 SL123", "Archive", "#580" and "Sec. 4"

Why Did the Deep-Sea Ecosystem in the Eastern Mediterranean Collapse 10,000 Years Ago?

During a dramatic climate change around 10,000 years ago, most bottom-dwelling organisms in the eastern Mediterranean Sea died. Using climate…

What Principle Determines Climate Statistics?

Weather appears chaotic and random, which leads researchers to describe the climate using statistical quantities such as variances or spectra. While…

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…

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…

World map, gray continents, colors ranging from red to blue indicate sea surface temperature.

New Generation of Climate Models Sheds First Light on Long-Standing Pacific Puzzle

Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean accompanying global warming.…

Fewer Storms, More Extremes

Storms over the northeast Atlantic and the German Bight regularly cause major damage, placing a strain on people and the environment. At the same…
