The 7 most devastating climate disasters of summer 2021

(CNN)The climate crisis ravaged the United States this summer. As the West struggled with unrelenting drought and dozens of wildfires, a deadly heat wave seared the Northwest in June. Months later, back-to-back hurricanes -- Henri and Ida -- slammed the Northeast, breaking all-time rainfall records.

Beyond the US, China and Germany experienced deadly flooding events in July, as Canada and southern Europe battled pernicious wildfires of their own. Meanwhile, precipitation at the summit of Greenland fell as rain and not snow for the first time on record.
"It was impossible to ignore climate change this summer," Rachel Licker, a senior climate scientist with the Union of Concerned Scientists, told CNN. "And unfortunately, this isn't a one-time thing ... this is what we can expect more of, especially if we don't get off fossil fuels and invest in measures to build our resilience as soon as possible."
After months of deadly extremes, Americans' feelings on the climate crisis has evolved dramatically. For the first time, a majority of Americans now believe that the US is facing the consequences of a warming world, according to a new poll from the Yale Program on Climate Change Communication.
Here's what the US experienced this summer.

7. Hurricane Henri

Members of the New Market Volunteer Fire Company perform a secondary search in Helmetta, New Jersey, during an evacuation effort following a flash flood from Tropical Storm Henri.
Hurricane Henri, after weakening to a topical storm, flooded parts of the Northeast in late August with a deluge of rain from New Jersey to southern New England.
The storm set a new record for the most rain in a single hour in New York City -- nearly two inches of rain fell in Central Park from 10 p.m. to 11 p.m. on August 21, according to the National Weather Service. Nearly 5 inches of rain fell in New York City the following day, which also set a record for the date.
Tens of thousands of homes were left without power across the Northeast, with more than 42,000 customers left powerless in Rhode Island alone.
Extreme rainfall rates are becoming more common because of human-caused climate change, scientists say. Scientists reported in August that "the frequency and intensity of heavy precipitation events have increased since the 1950s over most land area."
