Forecasters warn this year’s El Niño could become one of the strongest on record, potentially peaking around a 3.9°C anomaly in December and driving higher global temperatures along with widespread droughts, floods, and shifts in rainfall and humidity. The impacts will vary by region and will be tracked with monthly updates, aided by a climate-change–adjusted index that separates El Niño warming from long-term ocean warming.
Europe is enduring a major heat wave as a high‑pressure heat dome pushes temperatures well above seasonal norms, yet air conditioning remains rare there (about 20% of homes) compared with the United States. Experts point to a historical lack of need, higher energy costs, and older, energy‑efficient but non‑AC buildings, plus planning hurdles in some areas. As demand grows, Europe’s AC stock is expected to rise (IEA projects 275 million units by 2050), but cooling that relies on fossil fuels risks locking in emissions, so the continent faces policy and design choices to improve energy efficiency and resilience while pursuing climate targets for 2050.
France reports three deaths linked to extreme heat as Bordeaux nears 42°C (107.6°F) and a red heatwave alert covers nearly 50 regions; across Europe, Spain also faces red alerts while authorities anticipate several days of scorching conditions with little overnight relief, thousands of French schools are closing or adjusting schedules, wildlife shelters are coping with heat, and Spain is enforcing workers’ rights to adjust hours or take paid leave during heat alerts.
Forecast models show a 'super' El Niño is increasingly likely by late 2026 into 2027, with central Pacific sea-surface temperatures possibly 2–4 C above average (extreme scenarios near 4 C). This would raise global temperatures and intensify heat waves, droughts, heavy rainfall and other extreme weather; 2026 is already on track to be among the warmest years, and 2027 could become the hottest on record. While confidence grows, the spring predictability barrier means some uncertainty remains, and the exact outcome will unfold in the coming weeks as monitoring continues.
March was the hottest month on record for the continental U.S. in 132 years, with February also extremely warm and more than 19,800 daily heat records logged; the 12-month period from April 2025 to March 2026 was the warmest on record. Scientists link the anomalies to human-caused climate change and expect a super-strong El Niño to form later this year, likely pushing global temperatures to new highs into 2026–2027 and reshaping weather patterns—potentially reducing Atlantic hurricanes but boosting Pacific activity and easing drought in the Southwest.
Climate change is lengthening pollen seasons, potentially worsening allergy symptoms for millions of Americans as tree, grass and weed pollen rise earlier and higher; experts recommend checking local pollen counts, starting treatment before peak pollen, using high-efficiency air filters, and keeping windows closed to reduce indoor pollen exposure.
Since 1980, the Arctic’s minimum sea ice has shrunk by about 1.1 million square miles (roughly the size of Argentina), at a rate of about 12.2% per decade, with projections of ice-free summers by around 2050. The visualization (NASA/World Bank data) maps ice loss against country land areas, highlighting geopolitical and shipping shifts as Arctic routes open up. Global powers, including China with its Polar Silk Road and the Northern Sea Route, are preparing for a more accessible Arctic, while the region also holds significant oil potential (~412 billion barrels) and Greenland’s rare-earth reserves (~1.5 million metric tons).
A 5,000-year-old Psychrobacter bacterium retrieved from the Scarisoara Ice Cave in Romania is resistant to 10 antibiotics and carries more than 100 resistance genes, showing that antibiotic resistance evolved naturally long before modern antibiotics and highlighting the dual risks and opportunities of melting ice for public health and drug discovery.
Portugal’s deadly storms caused widespread damage and displacement, exposing long‑standing planning flaws like soil sealing, inadequate drainage, and aging infrastructure. Experts argue climate risks must be central to urban design and advocate nature‑based solutions—more green space and retention basins—citing Setúbal’s successful basin as a model, though funding and maintenance remain ongoing challenges.
A Nature Sustainability study projects that under a 2C warming, the number of people exposed to extreme heat would rise from about 1.54 billion in 2010 to 3.79 billion by 2050, with the heaviest impacts in India, Nigeria, Indonesia, Bangladesh, Pakistan and the Philippines; the biggest shifts occur early around the 1.5C mark, changing energy needs by boosting cooling demand in the southern hemisphere and reducing heating demand in the north, underscoring the urgency of adaptation and rapid emissions cuts.
Scientists sequencing the woolly rhino genome from preserved muscle found in a 14,400-year-old wolf pup’s stomach reveal the rhino population remained viable in northern Siberia until near the end of the Ice Age, with extinction likely driven rapidly by climate warming rather than human hunting.
King tides and heavy rain caused significant flooding in Marin County, California, inundating roads and homes, with residents experiencing unprecedented water levels and sharing community efforts to manage the flooding.
Burning wood emits more carbon dioxide than fossil fuels, but there are ways to improve the environmental impact of wood fires, such as better fire-building techniques and choosing sustainable wood sources.
Greenland has been shifting northwest by about two centimeters annually over the past 20 years due to ice melt caused by climate change, affecting its size and shape, with implications for geoscience and navigation; this movement underscores the accelerating impact of global warming on the Arctic, prompting increased awareness and conservation efforts worldwide.
Hurricane Melissa is intensifying into a rare Category 5 storm heading towards Jamaica, bringing life-threatening flooding, landslides, and widespread damage, with warnings issued for surrounding regions including Haiti, the Dominican Republic, and Cuba. Preparations are urged as the storm is expected to weaken slightly before landfall, but impacts will remain severe.
