That's about 1 million square kilometers less ice than the previous winter record set in 1986. The summer Antarctic sea ice extent also hit a record low in February, breaking the previous mark set in 2022. While climate change is contributing to melting glaciers in Antarctica, it has been less certain how warming temperatures are impacting sea ice near the southern pole. Sea ice extent there grew between 2007 and 2016. The shift in recent years toward record-low conditions has scientists concerned climate change may finally be presenting itself in Antarctic sea ice.

Sea ice levels in Antarctica are at an all-time low, the National Snow and Ice Data Center reports. Levels of sea ice in the region have reached record minimums this year, like in 2017 and 2022. Sea ice, the water that freezes on the surface of the sea in the Arctic and Antarctic hemispheres, has been decreasing in both regions. In Antarctica, sea ice levels reached record lows at least twice in 2023 after record minimums were detected in 2017 and 2022. Chart showing the levels of sea ice in Antarctica.

☆ Earth's mysterious core may be encased by an ancient ocean floor that has mountains 5 times taller than Everest

They believe an ancient ocean floor may be wrapped around our planet's mysterious core. The research suggests that Earth's core could be encased in an ancient ocean floor that features giant mountains five times the size of Mount Everest. Scientists have found looking at data from earthquakes that there may be a layer of ancient ocean floor coating the Earth's core. For them, the answer was clear: the layer was likely bits of ancient ocean floor, gobbled up over the ages from the surface as tectonic plates stretched and squished together. Due to its composition, the ocean floor is a perfect candidate for this layer, Hansen said.

☆ Climate change: The world has just experienced the hottest summer on record

CNN —As heat waves continue to bake parts of the world, scientists are reporting that this blistering, deadly summer was the hottest on record – and by a significant margin. The planet experienced its hottest June on record, followed by the hottest July – both breaking previous records by large margins. August was also the warmest such month on record, according to the new Copernicus data, and warmer than every other month this year except for July. The global average temperature for the month was 16.82 degrees Celsius – 0.31 degrees warmer than the previous record set in 2016. Patrick T. Fallon/AFP/Getty ImagesCountries in the Southern Hemisphere have also experienced startlingly warm winters, with well-above average temperatures recorded in Australia, several South American countries and Antarctica.

Last month was the hottest August on record, topping off the hottest summer on record, according to climate scientists. June through August was the warmest summer on record globally by a “large margin,” according to the European Union’s Copernicus Climate Change Service. Well-above average temperatures also occurred in Australia, several South American countries and around much of Antarctica, according to the service.

As well as flammable invasive plants sparking and spreading wildfires, climate change is enabling invasive species to move north – even to remote areas such as high mountains, deserts and frozen tundra. Preventing the arrival of new species into new regions is the best way to manage threats from invasive species, according to the report. For invasive species that have already taken hold, eradication has been a useful tool, especially on islands, according to the report.

It raced quickly down the Pacific coast and killed wild birds and marine mammals in staggering numbers. “The negative impact of this virus on Antarctic wildlife could be immense — likely worse than that on South American wildlife,” the report warns. More than 100 million birds breed in Antarctica and on the islands nearby, and many marine mammals swim in the surrounding waters. Some of those species, including the distinctive emperor penguin and Antarctic fur seal, crowd together in large colonies.

CNN —As rapidly warming global temperatures help push Antarctica’s sea ice to unprecedented lows, it’s threatening the very existence of one of the continent’s most iconic species: emperor penguins. Emperor penguins rely on stable sea ice attached to land for nesting and raising their chicks. For the past few years, scientists have been sounding the alarm about a steep decline in Antarctica’s sea ice. In mid-July, Antarctic sea ice reached the lowest level for this time of year since records began in 1945. Antarctic sea ice also helps regulate the planet’s temperature, reflecting the sun’s incoming energy back to space.

Four out of five emperor penguin colonies in Antarctica’s Bellingshausen Sea region very likely lost their chicks late last year because of disappearing sea ice underneath their breeding grounds, according to a new study. Parts of this coastal region had lost all of their sea ice by November, which was probably before penguin chicks had grown waterproof adult feathers and learned to swim. It’s the first time scientists have seen a widespread failure across multiple penguin colonies in a region, researchers said. “At the moment, we’re not sure if this is just a blip,” said Norman Ratcliffe, a seabird ecologist with the British Antarctic Survey and one of the authors of the new study. “But if this becomes a consistent phenomena in the longer term, clearly it’s going to have repercussions for the species.”

"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."
