Climate change doubled heat deaths in Belgium during the June 2026 heatwave
Reports and Proceedings
This July, we're exploring the science of heat. Whether it's shaping weather patterns, affecting marine ecosystems, influencing human health, or driving new technological solutions, heat plays a powerful role in our changing world. Join us as we examine the latest research uncovering how heat impacts people, places, and the planet.

A new rapid attribution study by Vrije Universiteit Brussel (VUB) finds that human-induced climate change made the June 2026 heatwave in Belgium 3.9°C hotter and more than doubled the number of heat-related deaths. Of the estimated 1,181 deaths statistically linked to the extreme temperatures recorded between 17 and 28 June 2026, 665 - or 56% - would not have occurred without anthropogenic climate change. This is the first time heat-related deaths during a specific Belgian heatwave have been attributed to human-induced climate change.
Two IPC PAS studies show how lignin-derived molecules can be transformed into compounds relevant to pharmaceutical research - at room temperature and atmospheric pressure and, in one case, without a transition-metal catalyst.
Sustainable packaging is only the beginning. What a medicine is made from - and how its ingredients are produced - matters just as much. Yet the synthesis of compounds for pharmaceutical research can still depend on fossil feedstocks, high temperatures, strong oxidants and metals that raise costs and complicate purification. Two recently published studies from Prof. Colmenares' group at IPC PAS demonstrate that cleaner chemistry can begin at the level of a single chemical bond [1][2].
At the heart of both studies is lignin, one of nature’s most abundant polymers and a major by-product of wood processing. Instead of simply burning it, chemists can use its aromatic structures as building blocks for much more valuable compounds. The teams combined this renewable feedstock with light and ultrasound. Light activates the catalyst, while inaudible sound waves produce cavitation: microscopic bubbles form and collapse violently. Energy is generated locally, where the chemistry happens, without exposing the whole system to extreme heat.
A twenty-year study, by researchers at Monash University in Australia, reveals that the number of people exposed to both wildfires and heatwaves globally, on the same days, has increased by 287 million over the two decades from 2000 to 2019, and that over half of the world’s population has experienced these conjoined weather events over the 20 years.
Co-exposure to heatwaves and air pollution from landscape fires has been increasing globally over the past two decades, according to a new analysis by Yao Wu and colleagues. Respiratory and cardiovascular health risks from landscape fire-related air pollution, as well as from extreme heat, are well documented. These health risks, and the incidence of the fires themselves, are amplified during stretches of extreme temperatures. Wu et al. found that 55.9% of the global population experienced increasing co-exposure between 2000 and 2019. On average, 916 million people each year experienced at least one co-exposure day, increasing by 287 million people per decade. The global annual average co-exposure was 1.3 days per person, rising from 1 day in 2000-2009 to 1.7 days in 2010-2019. During the study period, the top 5 countries with the highest annual averages of person-days of co-exposure to heatwaves and landscape fire smoke pollution were the Democratic Republic of the Congo, Indonesia, Mexico, Brazil, and the Russian Federation.
SAN ANTONIO — October 13, 2026 — Southwest Research Institute (SwRI) has added a 12-foot-diameter, 10-foot-long thermal vacuum (TVAC) chamber to simulate the vacuum and extreme temperatures of space to ensure spacecraft can survive that harsh environment. The chamber, which weighs roughly 40,000 pounds, is the newest addition to SwRI’s 74,000-square-foot Space Systems Integration Facility.
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.
