2017 Was the Second Hottest Year on Record

The evidence that climate change is becoming more and more of a problem continues.

In fact, 2017 was the hottest year without an El Niño by a wide margin – a whopping 0.17°C hotter than 2014, which previously held that record. Remarkably, 2017 was also hotter than 2015, which at the time was by far the hottest year on record thanks in part to a strong El Niño event that year.

America was also battered by climate-fueled extreme weather events in 2017. Research has already shown that global warming boosted Hurricane Harvey’s record rainfall (and associated flooding) by about 38%. California’s record wildfire season was similarly fueled by the state’s hot summer. The southwestern states were cooked by record hot summer temperatures this year, and global warming is making droughts in America and Europe worse. America was hit by 15 billion-dollar weather and climate disasters in 2017, and it will likely be the costliest such year on record once all of the hurricane damages are tallied.

These extreme weather events are expensive, and they’re a mere taste of what’s to come. Until we manage to cut global carbon pollution, temperatures will continue to rise and climate change consequences will become more severe.
