The world’s oceans were the hottest ever recorded in 2022, demonstrating the profound and pervasive changes that human-caused emissions have made to the planet’s climate. More than 90% of the excess heat trapped by greenhouse gas emissions is absorbed in the oceans. The records, starting in 1958, show an inexorable rise in ocean temperature, with an acceleration in warming after 1990.

Sea surface temperatures are a major influence on the world’s weather. Hotter oceans help supercharge extreme weather, leading to more intense hurricanes and typhoons and more moisture in the air, which brings more intense rains and flooding. Warmer water also expands, pushing up sea levels and endangering coastal cities.

The temperature of the oceans is far less affected by natural climate variability than the temperature of the atmosphere, making the oceans an undeniable indicator of global heating.

Last year is expected to be the fourth or fifth hottest recorded for surface air temperatures when the final data is collated. During 2022, we saw the third La Niña event in a row, which is the cooler phase of an irregular climate cycle centred on the Pacific that affects global weather patterns. When El Niño returns, global air temperatures will be boosted even higher.

This is helping to fuel the excessive rain along the west coast.

ETA - last CPC discussion (from December 2022) expected a possible gradual shift to ENSO Neutral from the 3-peat La Nina that we have been in - https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml

1. not good

and there have been warnings that were ignored for many years.

2. The Great Lakes are also getting warmer which means worse winter storms.

4. While storm-watching this past week

I've been monitoring several weather satellite graphics, and noticed a *massive* ocean surface temperature anomaly just below the Aleutian Island chain. Anyone know how anomalous this anomaly actually is? Perhaps an underwater volcanoe is getting ready to create a new island? Anyone have insight?

6. I don't know if that is an artifact of the cyclones spinning in the area

but here was the last SST anomaly graphic from NOAA's sat group as of yesterday - https://www.ospo.noaa.gov/Products/ocean/sst/anomaly/

5. Kicked and recommended.

Thanks for the thread BumRushDaShow

7. We are witnessing the ending of our own existence. Horribly unnecessary and a shameful legacy.

"we didn't start the fire" but the demand for fossil fuels, and land for exploitation, has accelerated dramatically in my lifetime. Largely due to exploding population and the raping of natural resources by pure greed. Very maddening and extremely scary for our kids, grandkids, and the ones to come.

8. We are so fucked.
