And even though it will take extensive scientific analysis to link climate change to last week’s cataclysmic floods in Europe, a warmer atmosphere holds more moisture and is already causing heavier rainfall in many storms around the world. There is little doubt that extreme weather events will continue to be more frequent and more intense as a consequence of global warming. A paper published Friday projected a significant increase in slow-moving but intense rainstorms across Europe by the end of this century because of climate change.
“We’ve got to adapt to the change we’ve already baked into the system and also avoid further change by reducing our emissions, by reducing our influence on the climate,” said Richard Betts, a climate scientist at the Met Office in Britain and a professor at the University of Exeter.
That message clearly hasn’t sunk in among policymakers, and perhaps the public as well, particularly in the developed world, which has maintained a sense of invulnerability.
The result is a lack of preparation, even in countries with resources. In the United States, flooding has killed more than 1,000 people since 2010 alone, according to federal data. In the Southwest, heat deaths have spiked in recent years.
Sometimes that is because governments have scrambled to respond to disasters they haven’t experienced before, like the heat wave in Western Canada last month, according to Jean Slick, head of the disaster and emergency management program at Royal Roads University in British Columbia. “You can have a plan, but you don’t know that it will work,” Ms. Slick said.
Other times, it’s because there aren’t political incentives to spend money on adaptation.
“By the time they build new flood infrastructure in their community, they’re probably not going to be in office anymore,” said Samantha Montano, a professor of emergency management at the Massachusetts Maritime Academy. “But they are going to have to justify millions, billions of dollars being spent.”
