📑 The first IPCC Assessment report came out in 1990. Prior to 1990, most parts of the world had already seen an increase in regional temperatures. Post 1990, regions with a high Human Development Index have seen the rate of warming increase.

The actual temperature change in different regions compared to a counterfactual world if the 1960–1990 warming trend had continued. It is clear that regions with a low HDI have warmed pretty much at the same rate post 1990. An increase in pollution levels in these regions while a decrease in pollution in high HDI regions, owing to the imposition of clean air acts, can explain some of these regional differences

The impact of ENSO on regional rainfall is nonlinear, which can have a severe impact on regional hydroclimate variability. In this new paper with @andrewkingclimate.bsky.social and @drjobrown.bsky.social, we assess CMIP6 models in capturing this nonlinearity - doi.org/10.1029/2024...
Figures describing the nature of the asymmetry of ENSO-rainfall teleconnections in two regions - East Australia and South-East Asia. East Australia experiences a stronger wet response during La Niña compared to the dry response during an El Niño, leading to a wet-type asymmetry. South-East Asia however, the effect is opposite with a stronger dry response during El Niño leading to a dry-type asymmetry Regional and performance of models in capturing the linear nature of ENSO-rainfall teleconnections for a July-June average.

In our recent GRL study- doi.org/10.1029/2024... - with @andrewkingclimate.bsky.social and Rob Ryan, we analysed global and regional accelerated warming. But, is an acceleration rate on the order of 0.001 degC/decade**2 really significant? The supplementary text contains the answer and it is - YES!!
