The world has been breaking climate records left and right. Here’s the short list:

  • 2015 was by far the hottest year since record-keeping began in 1880, shattering the record we just set in 2014.
  • The first three months of 2016 have already reached new highs.
  • The past 11 months globally were the hottest in 137 years of records.
  • A record amount of the Arctic Ocean never froze this winter. And Greenland’s ice started melting at its earliest date yet.
  • Carbon levels in the atmosphere showed their biggest-ever annual jump last year, according to readings at NOAA’s Mauna Loa observatory.

El Niño is partly to blame for warmer-than-usual temperatures, but scientists say we wouldn’t be seeing this record-breaking streak if global warming weren’t also fueling extreme temperatures.

Looking over this list of dubious accomplishments, I wondered what climate records we haven’t shattered in the last few years. So I asked a handful of scientists what’s left to fall.

Hot, hot, hot
