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.
2025 is among the hottest years on record, averaging about 1.44C above preindustrial levels, driven by long-term fossil-fuel emissions; a waning El Niño exposed underlying warming, and Copernicus warns the Paris 1.5C limit could be breached before the decade ends, as polar heat intensifies and sea ice declines.
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.
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.
In 2025, Earth's oceans reached a record-high heat content, absorbing 23 Zetta Joules of energy, which accelerates climate change impacts such as stronger storms, rising sea levels, and more extreme weather events, with uneven warming across regions fueling unpredictable weather patterns.
In 2025, the world's oceans absorbed record amounts of heat, intensifying climate disasters such as hurricanes, floods, and marine heatwaves, and contributing to sea level rise. This ongoing ocean warming, which is likely the hottest in at least 1,000 years, underscores the urgent need to reduce emissions to mitigate future climate impacts.
Iceland recorded its hottest Christmas Eve ever at 19.8°C due to warm tropical air and high pressure systems, highlighting the impacts of global warming, which has led to record heatwaves, melting glaciers, and the appearance of mosquitoes in the country.
Scientists report that 2025 was one of the three hottest years on record, surpassing the critical 1.5°C warming threshold set by the Paris Agreement, largely due to human activities like burning fossil fuels, leading to severe weather events and increased climate risks worldwide.
Despite a global boom in clean energy investments, 2025 saw significant setbacks in climate policies, led by the US and influenced by political shifts, which threaten to overshoot the Paris Agreement's temperature targets and exacerbate climate change impacts.
Scientists report that 2025 was one of the three hottest years on record, with climate change driven by human activities, especially fossil fuel burning, leading to severe weather events and surpassing the 1.5°C warming threshold set by the Paris Agreement, highlighting the urgent need for global action.
Australian scientists warn that Antarctica is experiencing rapid, irreversible climate changes, including shrinking sea ice, weakening ocean currents, and destabilizing ice sheets, driven by global warming. These changes threaten global sea levels and ecosystems, emphasizing the urgent need for deep emission cuts this decade to prevent irreversible damage.
A study published in Nature warns that hydrogen, often seen as a clean energy source, may contribute to climate change by prolonging methane's presence in the atmosphere, thus slightly increasing global temperatures. The rise in hydrogen emissions, mainly from human activities like industrial leaks and fossil fuel use, indirectly enhances warming by reducing atmospheric detergents that break down methane, highlighting the need for a deeper understanding of hydrogen's role in climate dynamics.
A new study shows that the rate of sea-level rise along U.S. coastlines has more than doubled over the past 125 years, contradicting a recent government report that downplayed acceleration, and highlighting the ongoing impact of climate change on sea levels and coastal communities.
The Arctic is experiencing its warmest year on record, with significant melting of permafrost and sea ice, leading to environmental changes such as rivers turning orange from leached metals and the 'Atlantification' of the region, which threaten global climate patterns and ecosystems, amid concerns over reduced monitoring due to funding cuts.
The Arctic experienced its hottest year on record from 2024 to 2025, with significant sea ice loss, increased precipitation, and warming temperatures, especially in winter, indicating a rapid and unprecedented climate shift that impacts global weather patterns, sea levels, and Arctic ecosystems.
