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.

There were just 57 confirmed unprovoked shark attacks last year, out of a global population of 8 billion, five of which were fatal. However, some places around the world have much higher rates of shark attacks than others, with the numbers rising with the passing years. Let’s take a look at the locations worldwide with the highest rates of shark attacks between 2012 and 2021 and the reasons they’ve become hot spots. South Africa (29 bites)South Africa had 29 unprovoked shark bites between 2012 and 2021, of which six were fatal. South Carolina (45 bites)None of the 45 unprovoked attacks in South Carolina in the decade-long time frame were fatal.

☆ Four alarming charts that show just how extreme the climate is right now

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.
