Copernicus has confirmed a new all-time record for daily global sea surface temperature, reaching 21.1°C on August 22, exceeding the previous record from March 2024. This "wrong-season" high, occurring in August when oceans typically cool, signals that persistent warming and El Niño effects are now overriding normal seasonal cycles.

Global warming has accelerated sharply, with the planet heating at roughly 0.35°C per decade over the past ten years, nearly double the rate of the previous 45 years. This acceleration is compounded by a record-breaking ocean heat event driven by human-caused warming and a strong El Niño, which is injecting more energy into storms.

This week's most significant climate science development is the confirmation that global warming is accelerating, with the planet warming at roughly 0.35°C per decade over the past ten years, a marked increase from the 0.2°C per decade rate observed between 1970 and 2015. Concurrently, new research indicates that carbon pollution has fueled a "massive expansion" of marine heatwaves in Europe, making this year's hottest sea periods "virtually impossible" in a preindustrial climate.

Global climate indicators deteriorated at an unprecedented pace in the first half of 2026, with a comprehensive assessment presented at the Bonn Climate Conference revealing that all 11 key climate metrics have worsened since the last IPCC evaluation. Human-caused warming reached 1.37°C in 2025, placing the 1.5°C Paris Agreement limit within approximately four years. Meanwhile, research into carbon storage by trees reveals a critical vulnerability: future forest carbon uptake may be significantly lower than expected as trees halt growth by mid-summer despite continued photosynthesis.

Global warming reached 1.37°C above pre-industrial levels in 2025, with Earth accumulating heat at an accelerating rate that will likely push temperatures past the 1.5°C Paris Agreement threshold by 2030. Simultaneously, a contentious scientific debate has erupted over climate attribution research — an emerging field measuring how much climate change worsened individual disasters — with fossil fuel interests actively campaigning to discredit it, suggesting billions in liability are at stake.

Earth's rotation is slowing faster than at any point in the past 3.6 million years due to climate change, according to new research. Simultaneously, freshwater methane emissions are being maximized by global warming, while sea level rise continues to accelerate with scientists now fully understanding its drivers. These findings underscore the unprecedented scale of modern climate impacts on fundamental planetary processes.

Scientists have formally abandoned studying a worst-case climate scenario (RCP 8.5), marking a significant shift in climate modeling strategy, while sea level rise accelerates due to warming oceans and melting ice sheets. The SEC has proposed rescinding federal climate disclosure rules for corporations, raising questions about climate transparency in financial markets.

A sweeping global analysis published this week found that nearly 80% of the world's river systems have been losing dissolved oxygen over the past four decades, with climate change identified as the primary driver. Meanwhile, scientists are warning that a potentially record-breaking El Niño event could hit the United States in 2026, amplifying heat extremes and wildfire risk. On the policy front, a debate intensified over how climate models should be updated to better reflect future planetary risks, as researchers called for a fundamental rethink of dominant climate and biodiversity scenarios.

Scientists are sounding fresh alarms about 2026 becoming an extreme climate year as the anticipated return of El Niño threatens to amplify already record-breaking conditions — including a record-low Arctic winter sea ice extent and more than 150 million acres burned globally in wildfires so far this year. A new global map published in *Nature* reveals thousands of cities worldwide have successfully cut greenhouse gas emissions, offering a rare note of optimism. Meanwhile, a Colombia-hosted "Beyond COP" fossil fuel transition summit is drawing cautious praise for putting scientists at the center of climate action talks.

A strong El Niño may be developing, and scientists warn that decades of past episodes may no longer reliably predict its future impacts as the planet continues to warm. New research from Scientific American finds that airborne microplastics could be amplifying warming by trapping heat in the atmosphere, adding an underappreciated feedback loop to climate projections. Meanwhile, James Hansen predicts 2026 will surpass 2024 as the hottest year on record, driven by an expected El Niño surge in the second half of the year.
