We have a good chance at being 2016 and 2020 this year with this nino. We'll probably get up to around .9 or .95c globally overall in the giss.

Ocean temperatures are off the charts, and El Niño is only partly to blame

In a world of worsening climate extremes, a single red line has caught many people's attention.

The line, which charts sea surface temperatures in the North Atlantic Ocean, went viral over the weekend for its startling display of unprecedented warming—nearly 2 degrees (1.09 Celsius) above the mean dating back to 1982, the earliest year with comparable data.

Ocean temperatures are so anomalously high that Eliot Jacobson, a retired mathematics professor who created the graph using data from the National Oceanic and Atmospheric Administration, had to "increase the upper bound on the y-axis," he said.

"I've been doing this for a long time, but this one was like, 'Oh my God, look at this,'" Jacobson said of the graph. "What is going on here?"

Fears of hottest year on record as global temperatures spike

Thu 15 Jun 2023 08.30 BST

Global temperatures have accelerated to record-setting levels this month, an ominous sign in the climate crisis ahead of a gathering El Niño that could potentially propel 2023 to become the hottest year ever recorded.

Preliminary global average temperatures taken so far in June are nearly 1C (1.8F) above levels previously recorded for the same month, going back to 1979. While the month is not yet complete and may not set a new June record, climate scientists say it follows a pattern of strengthening global heating that could see this year named the hottest ever recorded, topping 2016.

The long-term warming conditions caused by the burning of fossil fuels will likely receive a further pulse of heat via El Niño, a naturally reoccurring phenomenon where sections of the Pacific Ocean heat up, typically causing temperatures to spike across the world.

Last week, the National Oceanic and Atmospheric Administration (Noaa) said El Niño conditions are now present and will “gradually strengthen” into early next year. Michael Mann, a climate scientist at the University of Pennsylvania, said human-caused warming will be exacerbated by an event that typically adds between 0.1C to 0.2C (0.18F to 0.36F) to the overall global temperature.

“The global surface temperature anomaly is at or near record levels right now, and 2023 will almost certainly be the warmest year on record,” said Mann. “That is likely to be true for just about every El Niño year in the future as well, as long we we continue to warm the planet with fossil fuel burning and carbon pollution.”
