New research on climate change — data, not opinions.
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.
A groundbreaking climate attribution study reveals that extreme snow droughts could become routine in the US West by 2050 due to greenhouse gas warming, while new research on sea-level rise flooding in the UK quantifies unprecedented coastal vulnerability. Meanwhile, a National Academy of Sciences report on attribution science is advancing the field's ability to link specific extreme weather events to human-caused climate change.
The National Academies of Sciences released a landmark report validating climate attribution science, strengthening the scientific basis for extreme weather liability cases. Meanwhile, the EU faces its biggest climate policy battle of 2026 over carbon market reforms, and global sea surface temperatures continue breaking records, with daily SST data exceeding 20.86°C in June 2026.
Marine cloud brightening over the eastern Pacific could dramatically weaken the El Niño cycle and trigger major global weather pattern changes, according to new research, while scientists challenge a U.S. government report on human-caused climate warming. Global sea surface temperatures continued breaking records in June, with daily readings exceeding previous highs from 2023-2024.
Europe faces record-breaking heat intensified by climate change, with scientists launching new databases to track climate research while UN talks end in "gridlock." A major Nature Climate Change study reveals temperate regions are experiencing local extinctions from warming faster than tropical areas, challenging conventional climate impact assumptions.
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.
U.S. climate disclosure rules face regulatory rollback just as scientists abandon a worst-case emissions scenario, reshaping how climate risk gets measured. Meanwhile, the UN warns record global heat is nearly certain by 2030, with sea level rise now fully explained by warming waters and melting ice.
Scientists are updating the foundational scenarios used to model climate futures, with researchers now declaring the 1.5°C Paris Agreement goal "no longer plausible" and calling for a fundamental rethink of how climate and biodiversity models are constructed. Meanwhile, a record-setting glacier collapse in Antarctica and the EU's new climate adaptation activity report underscore the accelerating pace of physical change across Earth's systems.
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.
New research published this week reveals that hidden underwater channels in Antarctic ice shelves are dramatically accelerating melt rates from below, potentially fast-tracking sea level rise beyond current projections. A major global study warns that climate inaction could trigger 16 million deaths by 2050, while the EU, Brazil, and China launched a landmark coalition to strengthen carbon market integrity.
New research confirms that colored microplastics drifting in Earth's atmosphere are contributing to global warming, adding a troubling dimension to the plastics pollution crisis. Meanwhile, NASA's latest GISTEMP data confirms 2025 joined 2024 and 2023 as the three warmest years in the agency's 146-year record. On the policy front, both the Philippines-Singapore and Morocco-Norway bilateral carbon trading agreements signal expanding momentum for international carbon market cooperation ahead of COP31 in Antalya.
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.
This week's most significant climate developments include a new Nature Climate Change study arguing that AI foundation models could unify climate risk and societal response research, fresh predictions of higher-than-expected global warming for 2026 and 2027, and a landmark "Beyond COP" summit in which scientists presented fossil fuel phase-out pathways to a "coalition of the willing." Meanwhile, ocean warming is quietly eliminating sea-land breezes in major coastal cities — an overlooked climate threat that new research has now quantified.
New research published this week reveals alarming dual threats to global fertility from combined toxic and climate exposures, while Nature's climate science hub highlights that ocean warming is now reducing sea-breeze days in major coastal cities — an overlooked climate risk. Meanwhile, the Real Instituto Elcano released a policy analysis this week examining the path from the Paris Agreement to COP30, underscoring that decisive action and EU leadership remain critical to keeping climate goals within reach.
