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.”

Climate change: UN to unmask fossil fuel lobbyists at climate talks

1 hour ago

Oil, gas and coal representatives will have to disclose their industry ties at future climate meetings, the UN says.

For years, fossil fuel employees have been able to attend without having to be clear about their relationship with their companies.

Last year, over 600 industry participants were able to enter the COP27 meeting in Egypt.

Campaigners say the UN ruling is the first step to limiting the influence of polluters.

The new rules will be in place for the COP28 summit in November in Dubai, United Arab Emirates, one of the world's top oil producers. UAE oil company chief Sultan Al Jaber will preside over the summit, an appointment that has irked environmentalists.

Himalayan glaciers providing critical water to nearly two billion people are melting
Himalayan glaciers melting 65 percent faster than previous decade: study

Kathmandu (AFP) – Himalayan glaciers providing critical water to nearly two billion people are melting faster than ever before due to climate change, exposing communities to unpredictable and costly disasters, scientists warned Tuesday.

The glaciers disappeared 65 percent faster from 2011 to 2020 compared with the previous decade, according to a report by the International Centre for Integrated Mountain Development (ICIMOD).

"As it gets warmer, ice will melt, that was expected, but what is unexpected and very worrying is the speed," lead author Philippus Wester told AFP. "This is going much faster than we thought.”

Based on current emissions trajectories, the glaciers could lose up to 80 percent of their current volume by the end of the century…The glaciers feed 10 of the world's most important river systems, including the Ganges, Indus, Yellow, Mekong and Irrawaddy, and directly or indirectly supply billions of people with food, energy, clean air and income.

NASA Shows What 30 Years of Rising Seas Feels Like in Chilling New Animation

21 June 2023

NASA has released a chilling animation showing just how far sea levels have risen in the three short decades its satellites have been monitoring them.

The data visualization, released last week, is the work of Andrew J. Christensen, a data visualizer for the NASA Scientific Visualization Studio. By animating observed changes in global sea level captured by satellites whizzing overhead between 1993 and 2022, the imagery transforms a complex mix of numbers into something far more relatable.

In those 30 years, sea levels have risen by over 9 centimeters (about 3.5 inches). That might not sound like much, only a hand's length, but when those changes are visualized as water lapping at a ship-like window, it starts to feel very real.

This is insane, to be honest. I have a bad feeling this will be the new average.
