The observed circulation-induced trend is outside the multi-model range and the overall trend at the very low end of it over Midwestern US. While the circulation- and thermodynamic-induced trends, and the total trends are at the high end of the model range in Western Europe

Western Europe shows strong intensification of heat extremes, whereas the Midwestern US has experienced a slight decrease in daytime heat extremes since the mid-20th century, despite rising nighttime and summer average temperatures in the area

Our new study in @CommsEarth shows that circulation dampened the trend in heat extreme intensity over the Midwestern US, whereas it amplified the trend over Western Europe, at a rate outside the range of most models. @erichfischer @ssippel87 @usys_ethzh.

Just an updated analysis - In addition, avg maximum heat during 1-26 April broke the previous (1970-2021) records across the AFG, PAK, and parts of northwestern India by margin of 1-3 C. Also, heat anomalies (relative to 1970-2010) over these regions reach up to 8 C.
An analysis of ERA5 by my @ETH_en colleague @jitendra_iitb shows that the 10-day and 15-day seasonal heat records had already been broken across Afghanistan, Pakistan and northwestern India (colored regions in figure below) before the onset of last weekend's heatwave.

Droughts occurring at the same time across different regions of the planet could place an unprecedented strain on the global agricultural system and threaten the water security of millions of people.

The increase in compound droughts contributes to ~9-fold increase in agricultural area and population exposure to severe compound droughts with continued fossil-fuel dependence, highlighting the higher risk of simultaneous production shocks over multiple breadbaskets.

Historically, large number of these compound droughts are associated with ENSO. By end of this century, 3 out of 4 such events are expected to be driven by ENSO and half of them are associated with El Niño conditions alone along with warming.

Risk of spatially compound droughts increases by ~40% by mid 21st century and ~60% by end of 21st century, relative to late 20th century, under the high-emissions scenario.
