Climate Expert Warns Heatwaves Are Now ‘100 Times’ More Likely Due to Global Warming

In a recent interview on CNN’s Amanpour, climate author David Wallace-Wells, best known for his book The Uninhabitable Earth, sounded an urgent alarm about the accelerating frequency of extreme heat events. Speaking with Bianna Golodryga, Wallace-Wells highlighted that heatwaves have become ‘100 times’ more likely due to human-caused climate change, and stressed that the mounting human and economic costs are outpacing government responses.

The conversation focused on Europe’s deadly heatwaves, which have shattered temperature records and claimed thousands of lives in recent summers. Wallace-Wells pointed out that the same greenhouse gas emissions driving these heatwaves are also fueling other extreme weather events, from wildfires to floods, creating a cascading crisis that demands immediate and aggressive policy action.

Wallace-Wells criticized governments for falling behind on climate commitments, noting that even modest warming targets are slipping out of reach. He called for a fundamental shift in how societies value long-term resilience over short-term economic gains, warning that the costs of inaction will only grow more severe. The interview serves as a stark reminder that climate change is not a distant threat but a present-day reality reshaping our world.
