2020 was supposed to be cooler — it could be hottest on record

Just how far out of balance is earth’s climate system? This year will end as the first or second warmest year on record globally. It continues an unprecedented run of record heat — seven years and counting — dating back to 1880.

“That’s particularly surprising given that we have a La Niña event in the tropical Pacific. That tends to cool global temperatures a bit,” said Penn State University professor Michael Mann. “It’s way out of balance.”
