The most disastrous heatwaves are very extreme events with return periods of hundreds years, but traditionally, climate research has focussed on moderate occurring every couple years or even several times within a year. Here, we use three Earth System Model large ensembles to assess whether heat respond differently global warming than events. We find that the signal can be amplified dampened substantially compared extremes. This modulation is detectable already in mid-century projections. In mid-latitudes, it explained by changes event soil moisture-temperature coupling during hottest day depend interplay present moisture and as well projected precipitation changes. mechanism robust across models, albeit spatial uncertainties. Our findings highly relevant for risk assessments adaptation planning.

Abstract Extreme heat undermines the working capacity of individuals, resulting in lower productivity, and thus economic output. Here we analyse present future damages due to reduced labour productivity caused by extreme Europe. For analysis current impacts, focused on heatwaves occurring four recent anomalously hot years (2003, 2010, 2015, 2018) compared our findings historical period 1981–2010. In selected years, total estimated attributed amounted 0.3–0.5% European gross domestic product (GDP). However, identified losses were largely heterogeneous across space, consistently showing GDP impacts beyond 1% more vulnerable regions. Future projections indicate that 2060 might increase Europe a factor almost five 1981–2010 if no further mitigation or adaptation actions are taken, suggesting presence pronounced effects regions where these already acute.

Anthropogenic climate change profoundly alters the ocean’s environmental conditions, which, in turn, impact marine ecosystems. Some of these changes are happening fast and may be difficult to reverse. The identification monitoring such changes, which also includes tipping points, is an ongoing emerging research effort. Prevention negative impacts requires mitigation efforts based on feasible research-based pathways.

Abstract Anthropogenic changes in the variability of precipitation stand to impact both natural and human systems profound ways. Precipitation encompasses not only extremes like droughts floods, but also spectrum which populates times between these extremes.

We use a suite state-of-the-art climate models, with each model consisting single-model initial-condition large ensemble (SMILE), yielding at least 15 individual realizations equally likely evolutions future state for model.

Heatwaves often cause immense stress on human society and the natural environment. While heatwaves can be classified into daytime, nighttime, compound daytime-nighttime types, specific processes associated with different heatwave types remain poorly understood. In this paper, we identify mechanisms operating in (i.e., extreme heat during both day night) independent daytime nighttime southern China. Compound generally exhibit stronger temperature increases than either or types. Daytime are accompanied by increased downward shortwave radiation under a clear sky reduced cloud cover moisture. Nighttime characterized more cloudy moist conditions, longwave at surface night. A combination of these conditions for prevail heatwaves.

Abstract Single‐model initial‐condition large ensembles are powerful tools to quantify the forced response, internal climate variability, and their evolution under global warming. Here, we present CMIP6 version of Max Planck Institute Grand Ensemble (MPI‐GE CMIP6) with currently 30 realizations for historical period five emission scenarios. The power MPI‐GE goes beyond its predecessor ensemble by providing high‐frequency output, full range scenarios including highly policy‐relevant low SSP1‐1.9 SSP1‐2.6, opportunity compare complementary high‐resolution simulations. First, describe CMIP6, evaluate it observations reanalyzes MPI‐GE.
