Experiments with a climate model reveal that the tropical Pacific responds to increased atmospheric carbon dioxide levels in three distinct phases. The first phase is dominated by random fluctuations. After this, the tropical Pacific warms more slowly than surrounding regions, resulting in a relative cooling that is consistent with what has been observed in recent decades. The third phase, during which the eastern tropical Pacific warms more than the western Pacific, is expected to emerge over…

During a dramatic climate change around 10,000 years ago, most bottom-dwelling organisms in the eastern Mediterranean Sea died. Using climate simulations covering the past 21,000 years, researchers were able to provide a physically and biogeochemically consistent explanation for the origin, course, and end of this 4,000-year-long period for the first time.
Weather appears chaotic and random, which leads researchers to describe the climate using statistical quantities such as variances or spectra. While these reflect the random behavior of climate variables, such quantities are nevertheless well-defined as long as the external drivers of the climate system remain constant. In a new study, climate researcher Jin-Song von Storch reveals the constitutive principle underlying such climate statistics.
The Max Planck Institute for Meteorology and its partners in the WarmWorld project are inviting contributions to the km-Scale Modelling Summit, an international meeting that will be held in Hamburg from 20–24 July 2026. It will bring together experts in high-resolution Earth system modeling, observations, high-performance computing, and artificial intelligence. Abstracts can be submitted until 31 March 2026.
Julia Windmiller was appointed to the position of senior lecturer at Monash University in Australia, where she will study the interaction between tropical weather and climate. She remains connected to the Max Planck Institute for Meteorology, thanks to a joint project, among other things.
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 over Europe. A new study shows that climate models represent this relationship much more realistically when ocean dynamics are resolved in sufficient detail.
If the Amazon rainforest were completely cleared, extreme precipitation, heat stress, and high wind speeds would occur more frequently. This is the result of a recent study based on simulations using a kilometer-scale climate model.
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 complex. Researchers at the Max Planck Institute for Meteorology are helping to piece together the puzzle.
In a pre-industrial climate, the Greenland Ice Sheet can take on four different steady states, as demonstrated by simulations using a fully-coupled Earth System-Ice Sheet Model. This implies that a return to pre-industrial temperatures does not guarantee that the ice sheet will regrow to its full size once a significant portion has melted under higher temperatures. Instead, it could stabilize at 20 to 50% of its pre-industrial volume.
