At a gathering in Texas, near where floods killed 136 people last year, survivors are united on the need for urgent action

It may be a club none of its members actually want to be in, but the growing number of people in the US affected by extreme weather disasters are starting to organize into a political force.

Severe wildfires, floods storms and other calamities now touch the lives of huge numbers of Americans – about half of all people in the US by one estimate – as the climate crisis supercharges extreme events. Some survivors are now coalescing to push for improved disaster response and even action on the politically contentious issue of global heating.

Polls show that Democrats and Republicans in battleground states want to hear more from candidates about the climate crisis

Most Americans feel unease or alarm about the climate crisis and, in both red and blue states, want to know how political leaders are going to fix it. But in midterm election campaigns across the US, candidates have responded to this desire with near silence.

People in the US have this year endured a record hot summer as well as soaring costs, equating to roughly $2,000 per household, in extra energy and mortgage payments, due to the country’s dependence on a fossil fuel supply scrambled by Donald Trump’s decision to attack Iran.
