The ocean has now broken temperature records every day for more than a year. And so far, 2024 has continued 2023’s trend of beating previous records by wide margins. In fact, the whole planet has been hot for months, according to many different data sets. “There’s no ambiguity about the data,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies. “So really, it’s a question of attribution.”Understanding what specific physical processes are behind these temperature records will help scientists improve their climate models and better predict temperatures in the future.

☆ Data from sponges suggest the world has overshot a climate limit, new study says
▼ + stars: | 2024-02-05 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +5 min

These findings, published Monday in the journal Nature Climate Change, are alarming but also controversial. Other scientists say the study contains too many uncertainties and limitations to draw such firm conclusions and could end up confusing public understanding of climate change. Researchers say the results also suggest global temperature could overshoot 2 degrees of warming by the end of the decade. Changing that baseline would mean the world has already warmed at least 1.7 degrees (scientists say long-term global warming currently stands at between 1.2 to 1.3 degrees). Whatever the baseline for measuring global warming, what remains clear, experts say, is that the impacts will worsen with every fraction of a degree of warming.

The latest calculations from several science agencies showing Earth obliterated global heat records last year may seem scary. Former NASA climate scientist James Hansen, often considered the godfather of global warming science, theorized last year that warming was accelerating. That’s 0.27 degrees (0.15 degrees Celsius) warmer than the previous record set in 2016 and 2.43 degrees (1.35 degrees Celsius) warmer than pre-industrial temperatures. NASA and the United Kingdom Meteorological Office had the warming since the mid-19th century a bit higher at 2.5 degrees (1.39 degrees Celsius) and 2.63 degrees (1.46 degrees Celsius) respectively. It’s the third time in the last eight years that a global heat record was set.

☆ Oceans absorb 90% of the heat from climate change — here's why record ocean temps are so harmful

"Over 90 percent of the excess energy on earth due to climate change is found in warmer oceans, some of it in surface oceans and some at depth." Put simply, the greenhouse gases serve to trap more heat, some of which is absorbed by the ocean," Kirtman told CNBC. In addition to the daily record on July 31, the monthly sea surface temperature for July was the hottest July on record, "by far," Copernicus said. CopernicusThese record sea surface temperatures arise from multiple factors, including the El Niño weather pattern, which is currently in effect. "These climate variations occur when sea surface temperature patterns of warming and cooling self-reinforce by changing patterns of winds and precipitation that deepen the sea surface temperature changes."

☆ Earth just had its hottest July 'by a long shot,' NASA and NOAA say
▼ + stars: | 2023-08-14 | by ( Denise Chow | ) www.cnbc.com time to read: +4 min

NASA and NOAA together found that last month's average global surface temperature was 2.02 degrees Fahrenheit above the 20th-century average. Last month was also the fourth consecutive month that global ocean surface temperatures hit a record high, the scientists said. This trend in ocean warming carries far-reaching consequences, he said. Changes in ocean temperatures can also have enormous impacts on marine species and their broader ecosystems, he said. This phenomenon is characterized by warm ocean surface temperatures in parts of the Pacific Ocean and tends to boost global temperatures and influence weather conditions around the world.

☆ 2024 will probably be hotter than this year because of El Niño, NASA scientists say

Climate change, caused by burning fossil fuels, is unequivocally warming the Earth’s temperature, NASA scientists said. “It’s really only just emerged, and so what we’re seeing is not really due to that El Niño,” Schmidt told reporters. But, he added, it is likely that a sweltering 2024 will exceed it, precisely because of El Niño’s influence. “We anticipate that 2024 is going to be an even warmer year because we’re going to be starting off with that El Niño event,” Schmidt said. “This issue with ocean temperature is not a problem that stays in the ocean – it affects everything else.” Castillo noted hotter ocean temperatures can make hurricanes stronger and make ocean levels rice due to glacial melt.

The planet had one of its hottest years on record in 2022, as ocean heat soared and sea ice coverage in Antarctica melted to near-record lows, two federal science agencies announced Thursday. Last year was the fifth-warmest in recorded history, with global average surface temperatures that were 1.6 degrees Fahrenheit (about 0.8 degrees Celsius) warmer than the 20th century average, according to the latest yearly analysis by NASA. A separate report by the National Oceanic and Atmospheric Administration (NOAA) found that Earth had its sixth-warmest year on record. That’s not a robust change,” Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, said Thursday in a news briefing. The key thing is the long-term trends, and they’re very consistent from one record [to the next].”

☆ 2022 was one of the top 10 hottest years on record and the warmest La Nina year on record, according to government scientists

New data from the U.S. government shows that 2022 was one of the top 10 hottest years on record, with data going back to 1880. And of particular note, 2022 was the warmest year on record when there was a La Nina trade winds pattern, which is a weather event that has a cooling effect on global temperatures. According to both NOAA and NASA scientists, global temperatures were about 1.6 degrees Fahrenheit above their respective baseline averages from the 20th century. 2022 had a La Nina weather pattern, which generally lowers global temperatures compared to what they would have been in a normal weather pattern year. El Nino and La Nina refer to opposite weather patterns determined by trade winds that blow in the Pacific ocean.
