Recent data from NASA and NOAA, along with CopernicusECMWF ERA5 reanalysis, has confirmed that 2023 is the hottest year on record globally, surpassing the early industrial baseline average from 1881-1910. This record-breaking warmth is part of a concerning trend, with the ten warmest years all occurring within the last decade. Despite a sweep of extremely cold Arctic air that broke daily low temperature records across the U.S. in mid-January 2024, the overall global temperature continues to rise. Experts are questioning what will happen as the El Niño phenomenon fades, but the consensus is that global warming will persist. The Southern Hemisphere has also experienced record temperatures, and the warmth could put 2024 on track to rival 2023's global heat. The weakening of El Niño is observed with less atmospheric support and a seasonal cycle against it, with a strengthening cold pool below the surface indicating a potential end to the current El Niño cycle. Sea Surface Temperatures (SSTs) and subsurface heat have rapidly weakened, which is comparable to the 2016 super-El Nino event, despite much weaker El Niño conditions at present.

2024 is starting out notably warmer than the same time last year. Global temperatures have moved back into record territory over the past few days but are similar to what we saw during the 2016 super-El Nino event (despite much weaker El Nino conditions at present). https://t.co/0YOLdzVk2E

With less atmospheric support and a seasonal cycle working against it, El Niño has weakened. This is seen even with SSTs. Meanwhile, below the surface, is a strengthening cold pool. Subsurface heat has rapidly weakened and in a few months it will reach the surface, ending El Niño https://t.co/c1rtNn8xiz
Temperature records are falling on nearly every continent, and the warmth could put 2024 on pace to challenge 2023's exceptional global heat. https://t.co/ic18APv5T1
Temperatures are also warming in all months of the year for the Southern Hemisphere, and 2023 set quite a number of new records... Data from @CopernicusECMWF ERA5 reanalysis at https://t.co/e7aUaffEik https://t.co/AnGyzVoAkH
2024 is off to a record warm year, and the big question looms - what happens when the El Niño fades? Don’t expect a big cool down… global warming is relentless. https://t.co/hr6H5umICb
Extremely cold Arctic air and severe winter weather swept southward into much of the U.S. in mid-January 2024, breaking daily low temperature records from Montana to Texas. https://t.co/3g75hKN7nd
2023 HOTTEST YEAR GLOBALLY Data from NASA & NOAA is in and 2023 is now ranked the hottest on record globally when compared to the early industrial baseline average (1881-1910). Even more alarming is the fact that our 10 warmest years have all occurred within the last decade. https://t.co/lzHrbfddvB
