Drilling Into Antarctica’s Doomsday Glacier Ends in Setback but Yields Key Data

Scientists drilling into Thwaites Glacier with a hot-water borehole faced their instruments getting stuck about three-quarters of the way down and had to abandon the deployment, but the data recovered reveal warm, turbulent waters beneath the ice driving sub-ice melt. The findings improve understanding of the glacier’s instability, and researchers plan to return to continue studying it, given its potential to raise global sea levels by about 65 cm if it destabilizes.

Record-Breaking Ocean Warming Continues for Ninth Consecutive Year

The Earth's oceans have warmed for the ninth consecutive year in 2025, absorbing vast amounts of heat that contribute to climate change, extreme weather, and threats to marine ecosystems like coral reefs, with the warming penetrating as deep as 2,000 meters and likely to persist for centuries. Immediate action to reduce greenhouse gases could stabilize or reverse this trend.

Record-Breaking Ocean Heat in 2025 Signals Escalating Climate Crisis

Since 2018, the world's oceans have been absorbing record amounts of heat, with 2025 experiencing the highest heat absorption ever recorded, primarily due to climate change. This ongoing heat intake, equivalent to multiple atomic bombs, is a key indicator of global warming, affecting both surface and deep ocean temperatures, and will have long-lasting impacts on the planet.

Ocean Warming Endangers Microbe Crucial for Earth's Oxygen

A new study warns that rising ocean temperatures threaten Prochlorococcus, Earth's most abundant photosynthetic microbe, which produces nearly a third of the planet's oxygen. The microbe's optimal temperature range is 19-28°C, and temperatures above 30°C significantly reduce its growth, potentially leading to a decline in its population and impacting global oxygen levels and marine food webs. The study highlights the importance of understanding microbial responses to climate change and the potential shift in oceanic ecosystems.

Scientists Warn of Potential Permanent Shift in Earth's Oceans Due to Rising Heat

In 2023, unprecedented marine heatwaves affected 96% of the ocean surface, potentially pushing the world's oceans into a new, hotter state with serious consequences for climate regulation, marine life, and weather patterns, driven by factors like reduced cloud cover and weaker winds, raising concerns about a fundamental shift in ocean dynamics and the need for urgent research and mitigation efforts.

Scientists Discover Two Ocean Bands Heating at Record Speeds

Scientists have identified two major ocean bands near 40 degrees latitude in both hemispheres that are heating at unprecedented rates, influenced by shifts in wind patterns and ocean currents, with significant implications for climate, weather, and marine life. The study highlights the uneven distribution of ocean heat and the importance of long-term data to understand climate change impacts.

Scientists warn of accelerating ocean expansion and rising sea levels threatening coastlines

NASA reports that global sea levels rose by 0.23 inches in 2024, exceeding predictions and indicating an accelerating trend due to thermal expansion of oceans, primarily driven by climate change, which could lead to significant coastal flooding by 2100. Scientists warn that if warming continues, sea levels could rise by up to 6.6 feet, threatening coastal cities, and emphasize individual actions to reduce carbon footprints to combat this trend.

Study: Climate Change Amplified 2024 Atlantic Hurricane Intensity

Recent scientific reports highlight that human-caused ocean warming has intensified Atlantic hurricanes, increasing their wind speeds and resulting in more severe damage. Between 2019 and 2023, hurricanes experienced a 19 mph increase in maximum sustained winds due to climate change. In 2024, all 11 Atlantic hurricanes saw wind speed increases of 9 to 28 mph, with some storms being upgraded to higher categories. This intensification has led to a significant rise in economic damages, with climate change responsible for nearly half of the damages from major hurricanes like Helene and Milton.
