Is this the start of a cooler shift? Cap Allon of Electroverse notes that we may be in for another La Nina:
The La Niña climate pattern is forecast to make a return this fall and last through the winter of 2021-22, according to an official “alert” issued Thursday, July 8 by the Climate Prediction Center (CPC), which suggests further global cooling as we enter the new year.
La Niña –-a natural cycle marked by cooler-than-average sea surface temperatures (SSTs) in the central Pacific Ocean-– is one of the main drivers of global weather — it is usually associated with colder global temperatures, droughts in the southern U.S., and increased precipitation in Australia.
Entering a La Niña event when global temperatures are already around baseline is significant.
If the climate pattern has the expected affect then we should brace for global temps to continue their overall downward trend –which began in 2016 (see link below)– to levels well below the norm.
We could conceivably be looking at UAH readings some 0.4C below the 30-year average by the spring of 2022.
A La Nina watch has been issued by CPC.
The updated run of the NMME has La Nina returning during late fall and early winter 2021. This progression is also supported by similar analog years. #ENSO pic.twitter.com/gPMVokOfDH
