☆ Global ocean heat has been at record levels every single day for the last year

But he added that the records were unsurprising, given that ocean heat is being supercharged by human-caused global warming, a series of marine heatwaves and El Niño, a natural climate pattern marked by higher-than-average ocean temperatures. Global ocean warmth can add more power to hurricanes and other extreme weather events, including scorching heat waves and intense rainfall. Ocean heat sets the stage for more ferocious hurricanes. “Measuring ocean warming allows us to track the status and evolution of planetary warming,” Schuckmann told CNN. But, she added, it’s currently impossible to predict when ocean heat will drop below record levels.

☆ Climate change: The planet just shattered heat records for the ninth month in a row

CNN —Last month was the planet’s hottest February on record, marking the ninth month in a row that global records tumbled, according to new data from Copernicus, the European Union’s climate monitoring service. It’s yet another grim climate change milestone, as the long-term impacts of human-caused global warming are given a boost by El Niño, a natural climate fluctuation. Global temperatures in the first half of the month in particular were “exceptionally high,” according to the analysis. “At times, the records have been broken by margins that are virtually statistically impossible,” McNoldy told CNN. The Copernicus data “tells a familiar story of warming temperatures and shifting patterns of weather,” said Hannah Cloke, a climate scientist and professor at the University of Reading in the UK.

And February, as well the previous two winter months, soared well past the internationally set threshold for long-term warming, Copernicus reported Wednesday. February 2024 averaged 13.54 degrees Celsius (56.37 degrees Fahrenheit), breaking the old record from 2016 by about an eighth of a degree. Climate scientists say most of the record heat is from human-caused climate change of carbon dioxide and methane emissions from the burning of coal, oil and natural gas. Additional heat comes from a natural El Nino, a warming of the central Pacific that changes global weather patterns. The three-month period was the most any season has been above pre-industrial levels in Copernicus record keeping, which goes back to 1940.

☆ Scientists Are Freaking Out About Ocean Temperatures

For the past year, oceans around the world have been substantially warmer than usual. Last month was the hottest January on record in the world’s oceans, and temperatures have continued to rise since then. The heat wave has been especially pronounced in the North Atlantic. “The North Atlantic has been record-breakingly warm for almost a year now,” McNoldy said. Like, it doesn’t seem real.”Across the unusually warm Atlantic, in Cambridge, England, Rob Larter, a marine scientist who tracks polar ice levels, is equally perplexed.

☆ Hurricane season 2024: Unprecedented ocean heat and La Niña could combine with dangerous effect
▼ + stars: | 2024-02-18 | by ( Mary Gilbert | ) edition.cnn.com time to read: +5 min

CNN —Hurricane season is months away, but the waters where hurricanes roam haven’t received the memo. North Atlantic temperatures typically only go up from here, climbing in spring and reaching a maximum in early fall when hurricane season also peaks. The earlier La Niña arrives, the sooner it would influence hurricane season. “If you don’t want an active hurricane season, you would need La Niña to wait as long as possible to begin,” McNoldy said. Forecasters with NOAA’s Climate Prediction Center believe La Niña could arrive as soon as summer, but more likely by fall.

They propose a sixth category for storms with winds that exceed 192 miles per hour (309 kilometers per hour). Currently, storms with winds of 157 mph (252 kilometers per hour) or higher are Category 5. From time to time, experts have proposed a Category 6, especially since Typhoon Haiyan reached 195 mph wind speeds (315 kilometers per hour) over the open Pacific. Wehner said that as temperatures rise, the number of days with conditions ripe for potential Category 6 storms in the Gulf of Mexico will grow. “Perhaps I'll change my tune when a rapidly intensifying storm in the Gulf achieves a Category 6,” Corbosiero said in an email.

☆ The rest of 2023 hurricane season in 'uncharted waters' because of El Niño, record ocean temperatures
▼ + stars: | 2023-10-03 | by ( Mary Gilbert | ) edition.cnn.com time to read: +4 min

CNN —Experts fear an already active hurricane season could come to an eventful and exceptional end as unusually warm, storm-boosting ocean temperatures and a slow-to-emerge El Niño combine. The first half of October is typically the final stretch of the busiest time of the Atlantic hurricane season. The battle between warm ocean water and the effect of El Niño has posed a forecasting challenge throughout this hurricane season, as one factor is seemingly negating the other. “Usually as we get into the back half of the hurricane season, El Niño tends to dominate, even if the Atlantic is warm. “Is El Niño at some point going to say, ‘Forget this, I’m in charge?’” Klotzbach said.

ATLANTA (AP) — Hurricane Lee is rewriting old rules of meteorology, leaving experts astonished at how rapidly it grew into a goliath Category 5 hurricane. Political Cartoons View All 1148 Images"That extra heat comes back to manifest itself at some point, and one of the ways it does is through stronger hurricanes,” Shepherd said. More intense major hurricanes are also threatening communities farther inland, since the monster storms can grow so powerful that they remain dangerous hurricanes for longer distances over land. It has been 69 years since a major hurricane made landfall in New England, McNoldy said. Margot is far to the east of Lee, but as Margot strengthens it could affect the weather systems in the region that steer hurricanes.

☆ Hurricane Idalia chases Florida residents from the Gulf Coast as forecasters warn of storm surge

The result could be a big blow to a state still dealing with lingering damage from last year's Hurricane Ian. She had a message for the almost 900 residents who were under mandatory orders to evacuate the island near the coast of the Big Bend region. More than a dozen state troopers went door to door warning residents that storm surge could rise as high as 15 feet (4.5 meters). At 2 p.m. EDT Tuesday, Idalia was about 240 miles (390 kilometers) south-southwest of Tampa, with maximum sustained winds of 90 mph (150 kph), the National Hurricane Center said. Idalia's initial squalls were being felt in the Florida Keys and the southwestern coast of Florida on Tuesday afternoon, including at Clearwater Beach.

Record high levels of carbon pollution in the atmosphere and record low levels of Antarctic ice. Several all-time heat records were also broken earlier this month in Siberia, as temperatures shot up above 100 degrees Fahrenheit. In 2022, the world’s oceans broke heat records for the fourth year in a row. In late February, Antarctic sea ice reached its lowest extent since records began in the 1970s, at 691,000 square miles. The decline in sea ice also poses severe harm to the continent’s species, including penguins who rely on sea ice for feeding and hatching eggs.

Many of the most destructive and potentially deadly impacts of a hurricane — including storm surge, flooding and rainfall — are not accounted for in a storm's category number. "Hurricane Ian is a very large, slow-moving hurricane. "There have been several alternative scales proposed over the years and none have gained enough attention or traction by the National Hurricane Center," Collins said. "It is important to have such evidence before even proposing to the National Hurricane Center that this should be considered as a replacement." Kantha said the National Hurricane Center acts conservatively and carefully with changes, particularly those with legal implications.
