Many climate scientists are rather worried about this chart

This has been around on Twitter for a week or two, but the Guardian (from which this screenshot comes) has an article about it today:

 Update:  here's an AP news story about it, too.  Turns out that Michael Mann thinks it's not quite as important as some other climate scientists are saying.   

But there is a lot hanging on whether the next El Nino is super big, and causes big problems, or not.

I also noticed on Euronews last night that Spain is already sweltering under very unusual heat for this time of year, as is Asia.  Here's a BBC report on that:

Spain recorded its hottest ever temperature for April on Thursday, hitting 38.8C according to the country's meteorological service.

The record figure was reached in Cordoba airport in southern Spain just after 15:00 local time (14:00 BST).

For days a blistering heatwave has hit the country with temperatures 10-15C warmer than expected for April.

It's been driven by a mass of very hot air from Africa, coupled with a slow moving weather system.

"This is not normal. Temperatures are completely out of control this year," Cayetano Torres, a spokesman for Spain's meteorological office, told BBC News.

Experts were surprised by the scale of the heat experienced across southern Spain in recent days.

"This heat event in Spain is absolutely extreme, unprecedented with temperatures never seen before in April. In some locations records are being beaten by a 5C margin, which is something that has happened only a handful of times at weather stations around the world," said Maximiliano Herrera, a climatologist who runs an Extreme Temperatures twitter account.
