Normally, the hottest years on record occur when the underlying human-caused global warming trend gets a temporary boost from an El Niño’s enhanced warming in the tropical Pacific.
So it’s been a surprise to climate scientists that 2017 has been so remarkably warm — because the last El Niño ended a year ago. The National Oceanic and Atmospheric Administration (NOAA) reported Tuesday that the first half of 2017 was the second-warmest January-June on record for Earth, topped only by 2016, which was boosted by one of the biggest El Niños on record.
“As if it wasn’t shocking enough to see three consecutive record-breaking years, in 2014, 2015, and 2016, for the first time on record,” leading climatologist Michael Mann wrote in an email to ThinkProgress, “we’re now seeing near-record temperatures even in the absence of the El Nino ‘assist’ that the previous record year benefited from.”
Another day another article about things being warmer than expected or somehow shocking and surprising. It is disappointing that Mann chose not to ride Wallace-Wells coattails and sound the alarm but instead did the opposite. Even he isn’t putting it all together, isn’t getting just how fast it is going to happen. What a devastating situation for us all.
