Children are particularly vulnerable to climate change impacts and will face intensifying effects of climate change during their lifetimes. Here, we show that children already face disproportionate ex...

Recent surface warming and top-of-atmosphere energy imbalance point to higher future warming than previously estimated Previous constraints on transient climate response using observed surface te...

For 15 consecutive days, temperatures were over 32°C. Today, heatwaves are 3°C or 4°C hotter.

Predicting gray swan weather extremes, which are possible but so rare that they are absent from the training dataset, is a major concern for AI wea...

Abstract. From mid-2003 to mid-2024, a global decrease in low-cloud amount enhanced the absorption of solar radiation by 0.22±0.07 W m−2 per decade (±1σ range), accelerating the energy imbalance trend...

Limiting warming to 2C above pre-industrial temperatures may not be enough to prevent “extreme global climate outcomes”.

Extreme global climate outcomes may occur even under moderate 2 °C warming and may turn out to be more extreme than model-averaged projections at 3 °C or 4 °C warming.

Abstract. Parties to the 2015 Paris Agreement agreed to limit the long-term increase in global average temperature to well below 2 °C and pursue efforts to keep temperatures below 1.5 °C relative to p...

Long-term climate data suggest that the Arctic is entering a new era of bioclimatic extremes threatening cold ecosystems.

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

Artificial intelligence (AI)-based models are revolutionizing weather forecasting and have surpassed leading numerical weather prediction systems on various benchmark tasks. However, their ability to ...

Wie heiss kann es in der Schweiz maximal werden? Der Klimatologe Erich Fischer forscht zu Klima- und Wetterextremen an der ETH Zürich, auch zu Maximaltemperaturen in der Schweiz. Nun liegen belastbare...

The July 2021 extreme rainfall event in Western Europe appears near the upper bound of plausibility in the current climate, though alternative storylines revealing the potential for even more severe o...

Recent years have seen a rapid succession of climate-related records broken.
