In a flurry of recent fires and storms, the climate crisis has left unmistakable wounds on America. Even in a tumultuous year not short of anguish elsewhere, scientists warn the climate-fueled disasters of 2020’s summer point to major shifts that will upend Americans’ lives like no other threat.
The American west has experienced its biggest year of fire on record, with blazes the collective size of Connecticut roaring across a tinderbox-dry landscape, consuming thousands of buildings, claiming several dozen lives and turning the Bay Area’s sky an eerie orange.
Why some US cities are plotting a ‘green recovery’ after the pandemic

Meanwhile, the Atlantic has been so festooned with hurricanes – at one stage this month five storms were strung out across the ocean at once – that meteorologists exceeded their 21 English-language names for major storms and for only the second time had to turn to the Greek alphabet. Appropriately, the two phenomena met on 15 September, when wildfire smoke pouring across the country wafted into Paulette, yet another tropical storm, off the eastern seaboard.
Such events are consistent with a heating-up planet, according to scientists, with studies showing that hurricanes are becoming stronger as ocean waters warm up and the atmosphere holds more water vapor. In the west, prolonged, intense heat – perhaps the hottest atmospheric temperature ever recorded on Earth occurred in California in August – has dried out forests and soils, making them more susceptible to huge conflagrations.
Add in the floods that have soaked swaths of the midwest and the Arctic sea ice that just shrank to its second lowest extent on record and it’s clear climate impacts are now piling upon America in multiples.
“The changes from greenhouse gas emissions on the Earth’s climate system ain’t pretty and they do not come alone,” said Camilo Mora, an environmental scientist at the University of Hawaii and lead author of research that found climatic extremes are causing 400 different types of impacts upon humanity.
These threats are making people “unhealthy, thirsty, poor and homeless”, Mora said. “Climate change is like a horror movie with 400 endings to choose from.”
