Arctic Winter Sea Ice Nears Record-Low Max as Global Heat Pushes Extreme Records

Arctic sea ice reached its lowest winter maximum on record, essentially tying last year at about 5.52 million square miles; this diminished winter growth could hasten the summer melt, influencing climate patterns, shipping routes, and wildlife. Meanwhile, March heat records broke across the U.S., Mexico, Australia, Northern Africa, and Northern Europe, with Antarctica logging a record-cold day, underscoring a planet-wide pattern of extreme temperatures tied to warming.

Arctic winter sea ice near record low as global heat records surge

Arctic sea ice reached its winter maximum at about 5.52 million square miles, roughly tying the lowest on record and about 525,000 square miles below the 1981-2010 winter average, signaling a steady decline as warming continues. The smaller ice pack means less sunlight reflected, allowing more heat to enter the oceans and potentially affect the summer melt and weather patterns. Antarctica meanwhile posted its coldest March day on record; melting sea ice does not raise sea levels, but the broader loss signals climate disruption with implications for ecosystems and shipping routes.

Planet's Heat Imbalance Hits Record High as Oceans Absorb Most Warming

Planet's Heat Imbalance Hits Record High as Oceans Absorb Most Warming

The World Meteorological Organization warns that Earth's energy imbalance has reached a record high, with about 91% of excess heat absorbed by the oceans, driving unprecedented ocean warming and higher surface temperatures. The period 2015–2025 was the hottest on record, and a shift from La Niña to El Niño could push temperatures even higher, underscoring the urgent need for climate action.

Global warming speeds up after 2015, raising risk of 1.5°C breach before 2030

Global warming speeds up after 2015, raising risk of 1.5°C breach before 2030

New analysis from the Potsdam Institute finds that after removing natural variability (El Niño, volcanic activity, solar cycles), the rate of global warming has accelerated since around 2015, with recent decades warming ~0.35°C per decade—faster than the ~0.2°C per decade from 1970–2015—across five datasets. If this pace continues, the 1.5°C limit could be exceeded before 2030. The study focuses on the pace, not the causes, and underscores the need for rapid CO2 emission cuts.

Planet warming accelerates: new study finds acceleration since 2015

A study published in Geophysical Research Letters finds that global warming has accelerated since 2015, with Earth warming about 0.35°C in the last decade—faster than the roughly 0.2°C per decade observed from 1970 to 2015. If this pace continues, the 1.5°C Paris target could be breached before 2030, underscoring the urgency of reducing CO2 emissions.

Planet warms faster than at any point in modern records, study warns

A new study finds global warming is accelerating, jumping from under 0.2°C per decade (1970–2015) to about 0.35°C per decade in the last decade after filtering out natural factors; if this pace continues, the 1.5°C long‑term limit could be breached before 2030, with the timing varying across datasets. While attribution to forced warming vs natural variability remains debated, the acceleration aligns with climate models and underscores the urgency of reducing CO2 emissions to zero to avoid tipping points.

New study finds global warming is accelerating, raising chances of hitting 1.5°C sooner

A new paper in Geophysical Research Letters reports that Earth's warming has accelerated significantly in the last decade (about 0.35°C per decade from 2015–2025, up from ~0.2°C/decade 1970–2015), suggesting the 1.5°C limit could be breached earlier than expected if the trend continues. While multiple datasets show the acceleration, some scientists disagree, noting that recent warming could reflect natural variability or the end of aerosol cooling, and stressing the need for continued monitoring to confirm a lasting shift.

Trump Doubts Global Warming as Historic Cold Wave Grips U.S.

President Donald Trump posted on Truth Social claiming a record-cold spell proves global warming is a hoax, a view at odds with scientific consensus that climate change can coincide with heavy snowfall; forecasters warn of sub-zero temperatures and disruptions across parts of the U.S., while experts note that long-term trends and fossil-fuel policies remain central to Trump’s messaging.

Earth nears 1.5C barrier as 2025 is third-warmest year on record

Earth nears 1.5C barrier as 2025 is third-warmest year on record

Copernicus data show global temperatures about 1.4C above pre-industrial levels, with 2025 the third-warmest year on record at about 1.47C; 2024 remains the hottest year at around 1.6C, and the three-year stretch has briefly exceeded 1.5C, indicating the world is on pace to breach the Paris Agreement’s 1.5C target this decade due to greenhouse gas emissions and intensified heat in Europe and polar regions.

La Niña cools 2025 but planet stays on record-hot streak, scientists warn

Global temperatures in 2025 averaged about 1.4C above pre-industrial levels, cooler than 2024 due to La Niña, but the last three years have been the warmest on record. Despite natural cooling, human-caused emissions continue to drive long-term warming, bringing the world closer to the 1.5C target and signaling more heat records and extreme weather unless emissions are sharply reduced and adaptation is intensified.
