Germany's 2.5°C Temperature Rise Fuels Deadly Heatwaves and Costly Disasters

Last year was only the eighth-hottest on record—a welcome respite after the record-breaking heat of 2024. But what "welcome respite" means in an era of climate change is laid bare in the annual report by Germany's National Meteorological Service (DWD): 150 percent more days above 35°C and 50 percent more above 30°C. And this despite just two relatively brief heatwaves—though, unusually, they engulfed the entire country, striking first in late June to early July and again in mid-August.

A "relaxed" year amid escalating global heating thus translates to: between 1,200 and 3,700 heat-related deaths, predominantly among the elderly, according to the Robert Koch Institute; €2.6 billion in damages from natural disasters, per the insurance lobby; and a fatal train derailment caused by torrential rain. Meanwhile, Europe saw more forest burned than ever before since records began.

Farmers, however, caught a break last year. After one of the driest springs on record, unusually heavy July rains—according to the DWD—prevented "significant agricultural losses."

None of this can be attributed solely to climate change, yet heatwaves, most natural disasters, droughts, wildfires, and landslides are all becoming more frequent as the planet warms. The only way to halt this trend is to stop burning coal, oil, and gas as quickly as possible, to end deforestation, and to cease draining peatlands. But "halt" here means one thing: preventing conditions from worsening beyond their current state. Germany is already 2.5°C hotter today than before industrialization, and the trajectory is still upward—we're still flooring the CO₂ accelerator.

Incidentally, we don't even know precisely how fast the climate would stabilize if global emissions were cut to net zero. Temperatures might rise slightly further—or even dip. That's without accounting for the tipping points we're hurtling toward at breakneck speed. Which makes it all the more insane that for years, we've been pushing the planet's physical limits to the absolute brink.
