Analysis of recently digitized and transcribed historical weather data, until recently only available as handwritten archives in the Democratic Republic of the Congo and in Belgium, shows consistent warming trends across the Congo Basin

East Asian summers prior to the late 1990s were primarily affected by tropical oceans and their accompanying phenomenon, El Niño-Southern Oscillation (ENSO). However, in recent years this has appeared to hold less sway on East Asian (EA) summers, and primary influences on the prevalence of heatwaves in EA summers have shifted to the presence of newly formed ice (NFI) in the Arctic and the East Asian jet stream (EAJS). This is thanks to an anomalous anticyclone phenomenon, propelled by a reversal of circulation from westerly to easterly, bringing in colder winds from the Arctic Oscillation and cooling down the EA summer climate.

A leading U.S. beef industry trade association knew by 1989 that cattle contributed to global warming but focused its response on protecting consumer demand through public relations, according to a new study examining a decade of industry records.

Climate policy models usually assume people hold accurate beliefs about climate damages. A new study builds disinformation into a climate–economy model and finds that informed democratic majorities can deliver stronger carbon taxes than a politically constrained planner, but this advantage collapses abruptly once disinformation tips the majority. Late and persistent disinformation yields the most severe warming, while counter-disinformation efforts can largely restore effective policy.

A major new report from the European Society of Cardiology sets out how health services need to protect vulnerable patients during heatwaves. It details the need for hospital surge capacity during heatwaves, proactive home healthcare to monitor patients and provide cooling resources – such as fans, suitable storage for medication and watching out for signs of dehydration and overhydration in vulnerable patients.

Internal documents show that the trade association for U.S. beef production knew about livestock’s outsized role in global warming by 1989 and undertook strategic communications operation to convince the public otherwise.
