‘Damned if we do but completely stuffed if we don’t’: heatwaves will worsen longer net zero is delayed

<p>A new study suggests heatwaves will not revert back towards preindustrial conditions for at least 1,000 years after emissions target reached</p><ul><li><p><a href="https://www.theguardian.com/environment/2025/mar/10/sign-up-for-the-clear-air-australia-environment-newsletter-with-adam-morton?CMP=cvau_sfl">Sign up for climate and environment editor Adam Morton’s free Clear Air newsletter here</a></p></li></ul><p>Heatwaves will become hotter, longer and more frequent the later net zero emissions is reached globally, new research suggests.</p><p>Scientists at the <a href="https://www.21centuryweather.org.au/">ARC Centre of Excellence for 21st Century Weather</a> and Australia’s national science agency, the CSIRO, simulated how heatwaves would respond over the next 1,000 years, examining the differences for each five-year delay in reaching net zero between 2030 and 2060.</p> <a href="https://www.theguardian.com/environment/2025/nov/17/heatwaves-hotter-longer-more-frequent-net-zero-emisisons-delay">Continue reading...</a>
