Extreme Weather Events

The Briefing

  • We’re already seeing the impact of climate change—today, droughts, heatwaves, and extreme rainstorms are 2x more frequent than they were a century ago
  • In less than a decade, Earth’s climate is expected to warm another 0.5°C
  • If this happens, heatwaves will be 4.1x more frequent than they were in the 1850-1900s

The Accelerating Frequency of Extreme Weather

The world is already witnessing the effects of climate change.

A few months ago, the western U.S. experienced one of the worst droughts it’s seen in the last 20 years. At the same time, southern Europe roasted in an extreme heatwave, with temperatures reaching 45°C in some parts.

But things are only expected to get worse in the near future. Here’s a look at how much extreme climate events have changed over the last 200 years, and what’s to come if global temperatures keep rising.

A Century of Warming

The global surface temperature has increased by about 1°C since the 1850s. And according to the IPCC, this warming has been indisputably caused by human influence.

As the global temperatures have risen, the frequency of extreme weather events have increased along with it. Heatwaves, droughts and extreme rainstorms used to happen once in a decade on average, but now:

  • Heatwaves are 2.8x more frequent
  • Droughts are 1.7x more frequent
  • Extreme rainstorms are 1.3x more frequent

By 2030, the global surface temperature is expected to rise 1.5°C above the Earth’s baseline temperature, which means that:

The Briefing

  • An average of 70,000 wildfires blaze through the U.S. each year
  • These fires destroy approximately 5.8 million acres of land on a yearly basis
  • Over 43,000 fires have started across the U.S., burning 5 million acres of land as of Sept 3, 2021

30 Years of Wildfires in America

This summer, record-breaking droughts and relentless heat waves have fueled disastrous wildfires across the United States. It’s gotten so bad, the state of California has decided to shut down all national parks for two weeks to stop the spread.

But how disastrous has this year been compared to previous years? This graphic gives a historical look at the number of wildfires in America that have occurred each year since 1990, and the acres of forest land scorched during that period.

In the U.S., an average of 70,000 wildfires burn through 5.8 million acres of land each year. But some years have been worse than others.
