A record amount of California is burning, spurred by a nearly 20-year mega-drought. To the north, parts of Oregon that don’t usually catch fire are in flames.
Meanwhile, the Atlantic’s 16th and 17th named tropical storms are swirling, a record number for this time of year. Powerful Typhoon Haishen lashed Japan and the Korean Peninsula this week. Last month, it hit 130 degrees in Death Valley, the hottest Earth has been in nearly a century.
Phoenix keeps setting triple-digit heat records, while Colorado went through a weather whiplash of 90-degree heat to snow this week. Siberia, famous for its icy climate, hit 100 degrees earlier this year, accompanied by wildfires. Before that, Australia and the Amazon were in flames.
Amid all that, Iowa’s derecho – bizarre straight-line winds that got as powerful as a major hurricane, causing billions of dollars in damages – barely went noticed.
Freak natural disasters – most with what scientists say likely have a climate change connection – seem to be everywhere in the crazy year 2020. But experts say we’ll probably look back and say those were the good old days, when disasters weren’t so wild.
“It’s going to get a lot worse,” Georgia Tech climate scientist Kim Cobb said Wednesday. “I say that with emphasis because it does challenge the imagination. And that’s the scary thing to know as a climate scientist in 2020.”

Colorado University environmental sciences chief Waleed Abdalati, NASA’s former chief scientist, said the trajectory of worsening disasters and climate change from the burning of coal, oil and gas is clear – and basic physics.
“I strongly believe we’re going to look back in 10 years, certainly 20 and definitely 50 and say, ‘Wow, 2020 was a crazy year, but I miss it,’” Abdalati said.
That’s because what’s happening now is just the type of crazy climate scientists anticipated 10 or 20 years ago.
“It seems like this is what we always were talking about a decade ago,” said North Carolina State climatologist Kathie Dello.
Even so, Cobb said the sheer magnitude of what’s happening now was hard to fathom back then. Just as the future of climate disasters is hard to fathom now.
“A year like 2020 could have been the subject of a marvelous science fiction film in 2000,” Cobb said. “Now, we have to watch and digest real-time disaster after disaster after disaster, on top of a pandemic. The outlook could not be any more grim. It’s just a horrifying prospect.”
“The 2030s are going to be noticeably worse than the 2020s,” she said.

Expect stronger winds, more drought, more heavy downpours and floods, Abdalati said.
“The kind of things we’re seeing are no surprise to the (scientific) community that understands the rules and the laws of physics,” Abdalati said.
“A lot of people want to blame it on 2020, but 2020 didn’t do this,” Dello said. “We know the behavior that caused climate change.”
Consider the world’s environment like an engine: “We have injected more energy into the system because we have trapped more heat into the atmosphere,” said World Meteorological Organization Secretary-General Petteri Taalas.
That means more energy for tropical storms as well as changes to rainfall patterns that bring drought to some places and heavy rainfall to others, Taalas said.
In California, where more than 2.3 million acres have burned, the fires are spurred by climate change drying plants and trees that then go up in flames, said University of Colorado fire scientist Jennifer Balch. California is in a nearly 20-year mega-drought, the first of its kind in the United States since Europeans arrived, Overpeck said.
Scientists also make direct connections between heat waves and climate change.
Some disasters at the moment can’t be directly linked to human-made warming, such as the derecho, Overpeck said. But looking at the big picture over time shows the problem, and it’s one that comes down to the basic physics of trapped heat energy.
“I am not an alarmist. I don’t want to scare people,” Abdalati said. “It’s a problem with tremendous consequences, and it’s too important not to get right.”
And so even though the climate will likely get worse, Overpeck is also optimistic about what future generations will think when they look back at the wild and dangerous weather of 2020.
“I think we’ll look back and we’ll see a whole bunch of increasingly crazy years,” Overpeck said. “And that this year, in 2020, I hope we look back and say it got crazy enough that it motivated us to act on climate change in the United States.”
