As parts of the globe prepare for scorching hot temperatures this weekend, climate scientists are stressing that the ongoing heat waves are not a temporary occurrence and world leaders need to take action to prevent them from becoming the “new normal.” UN Secretary-General Antonio Guterres recently commented that the world has entered an “era of global boiling,” coinciding with the meeting of G20’s environment ministers to discuss climate change. Guterres emphasized the necessity for world leaders to implement changes swiftly and set ambitious targets to reduce emissions and halt the rising trend of heat. Despite potentially being seen as alarmist, atmospheric physicist Kent Moore stated that it is crucial to convey the urgency of the situation, as the current state of climate is vastly different from what was previously anticipated. Moore referred to predictions by the Met Office, stating that the record-breaking temperatures witnessed in 2022 will be considered “average” by 2060 and even “cool” by the end of the century. He also highlighted research by the World Weather Attribution, which found that the heat waves impacting North America and Europe would have been nearly impossible without climate change. The goal set by world leaders is to prevent the average global temperature from exceeding 1.5°C; however, recent data from NASA’s Earth Observatory shows that the Earth has already surpassed 1.1°C. If extreme weather events are occurring at this stage, experts warn that conditions will worsen significantly if the 1.5°C threshold is exceeded. Canada, in particular, experienced heat waves with soaring temperatures and meteorologists from Environment and Climate Change Canada cautioned that such extreme events will become more frequent and intense. At the G20 environment ministers meeting, no consensus was reached on key climate issues, including emission peaks, clean energy adoption, and carbon taxation. The decisions made by the ministers will be relayed to G20 nation leaders for consideration ahead of a summit in New Delhi in September, which represents the last opportunity for a joint statement on climate this year.
