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.…

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…

View of Earth from space, showing detailed cloud formations, blue oceans, and the visible atmosphere along the horizon. The dark space forms the background.

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…

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…

Turquoise surf breaks against a stone seawall with drainage outlets; water washes the walkway, buildings to the left, open sea to the right, and a coastal town on the horizon under a pink‑blue sky.

How Will Sea Level Rise Affect the Global Economy?

Global sea level rise will have severe consequences for coastal regions and beyond. However, it has not been adequately represented in integrated…

Map of North America and the North Atlantic: land in grayscale, ocean color‑coded blue–red showing flow structures and eddies along the Gulf Stream; a prominent purple eddy sits east of the U.S. East Coast.

Tropical Cyclones and the Carbon Cycle: New Insights from A Model Simulation

For the first time, scientists have resolved extremely intense tropical cyclones and their effect on the ocean carbon cycle in a global Earth system…

This image shows a satellite view of the Earth, depicting the continents and oceans. The continents are represented in various colors, while the oceans are depicted in dark blue tones. The polar regions are shown in white, indicating the ice cover. The image quality is high, showing detailed structures of the Earth's surface and the oceans.

NextGEMS: The Start of a New Era in Climate Research

The nextGEMS project, which ended this year, has paved the way for a more natural use of Earth information systems with local granularity. Its major…

Map of the North Atlantic. Continents are black, and the ocean is colored with a blue-to-yellow color code.

How to Make Model Experiments on the Atlantic Overturning Circulation More Realistic

Melting ice in the Arctic is causing an increasing amount of freshwater to enter the North Atlantic, which is expected to result in a weakening of…

Excerpt from a world map showing America, Africa, and Europe. The continents are shown in black, while the ocean is depicted with a blue and white gradient, representing the kinetic energy in the ocean. Many finely resolved structures can be seen, such as eddies and currents.

Climate, Coasts, Complexity: Northern Germany at the Heart of Earth System Modeling

In September, Northern Germany becomes the meeting point for the international Earth System Modeling community. Three high-level scientific events,…
