NASA Just Announced That 2018 Was the Fourth-Hottest Year on Record

No, Trump, the polar vortex doesn’t mean climate change is going away.

It’s official: Last year was the fourth-hottest year on record, after only the previous three, according to separate figures released Wednesday morning by the National Oceanic and Atmospheric Administration (NOAA) and NASA.  

Several other monitoring organizations, including the United Kingdom Met Office, the World Meteorological Organization, and Berkeley Earth, a research group that released its data last month, reached the same conclusion.

“Everybody makes slightly different assumptions, but they’ve all come to the same result,” says Sean Sublette, a meteorologist at Climate Central, a climate research organization.  

Nine of the 10 hottest years on record have happened since 2005, with the last five all setting records. 2018 marks the 42nd consecutive year with an above-average global temperature. “A lot of people will argue that we’ve been warming since the ice age,” says Sublette. “Well that’s true, but we’re warming far, far faster than we did coming out of the ice age, by about 10 times faster.”

Last year, the United States saw increasing natural disasters, from record-setting wildfires in California to devastating hurricanes along the East Coast, costing hundreds of lives and almost $100 billion—a staggering number, but still down from the unprecedented $306 billion in 2017

The new government temperature data for 2018—the release of which was reportedly delayed by the government shutdown—came the morning after President Donald Trump’s State of the Union address. He made no mention of climate change. 

“It’s just another data point that speaks to how the Trump administration is absolutely neglecting the science that we know and really points to the need for real, tangible action on the ground,” says Thanu Yakupitiyage, communications manager for the environmental advocacy group “The Trump administration would rather make jokes like, ‘Where’s that global warming when you need it?’ And it’s not funny.”

During the polar vortex, the president mistakenly signaled—again—that the extreme cold was evidence against global warming. It is well understood that climate change can mean more extreme weather in general, whether hot or cold, and the new government data confirms a continued trend of global warming overall. 

Despite the continuing denial from the White House, Democrats are making climate change a central issue now that they control the House of Representatives. Today, they will hold the first climate hearings in years. Several congressional members brought top climate advocates as their guests to the State of the Union on Tuesday night. And the concept of a Green New Deal has garnered wide support even beyond Democratic circles. 

“This is longer-term work,” Yakupitiyage says. “The work that we’re doing around transforming the economy putting forward climate legislation exists now beyond the Trump administration.”  


In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
