New Orleans' watery future prompts urgent relocation planning, scientists warn

New Orleans' watery future prompts urgent relocation planning, scientists warn

A Nature Sustainability analysis warns rising seas could surround New Orleans by century’s end, with Louisiana wetlands largely disappearing (up to about 75% lost) and shoreline retreating as much as 62 miles, prompting researchers to urge proactive relocation planning to avoid chaotic outcomes and widening inequality. The city’s bowl-like geography and heavy flood risk raise concerns about vulnerable residents and culture, while some experts see relocation as a potential model for climate resilience, despite political and social hurdles that have stalled large-scale protective measures like sediment diversions.

BHP’s climate push stalls as leaked memos reveal delays to WA decarbonisation plans

Leaked internal BHP documents reviewed by the Guardian and ABC’s Four Corners show the world’s biggest miner has slowed or shelved major decarbonisation efforts in Western Australia’s Pilbara, including canceling a 50MW solar farm and 20MW battery at Jimblebar and delaying a nearly 500MW renewables project, with funding pushed to 2031 or later and options floated to postpone electrifying trucks and rail to 2035–2040 or take no action. Despite public commitments to reduce emissions, the company cites technology readiness as the constraint while facing shareholder pressure and criticism from climate groups urging faster action.

Megaconstellation Pollution Could Quietly Cool Earth by 2029, Study Finds

Megaconstellation Pollution Could Quietly Cool Earth by 2029, Study Finds

A study in Earth's Future warns that pollution from deorbiting megaconstellation satellites and rocket launches could reduce sunlight enough to have a cooling effect comparable to solar geoengineering by 2029; satellites already account for about a quarter of space industry climate impact and are expected to rise to 42% by 2029, with annual rocket soot around 870 metric tons; while this cooling might seem beneficial amid warming, the effects are uncertain and the lack of regulation poses risks, prompting calls for caution and policy action.

India hosts all of Earth's hottest cities in a single day, a startling climate signal

India hosts all of Earth's hottest cities in a single day, a startling climate signal

On April 27, 2026, AQI data showed every one of the planet's top 50 hottest cities was in India, with average peak temperatures around 112.5°F and Banda reaching 115.16°F—the day's highest. Experts call this unprecedented clustering a stark sign of the climate crisis, noting hotter summers, earlier heat onset, risks to farming and health, and the potential for an El Niño to worsen upcoming monsoon conditions in 2026.

Arctic Ocean’s Hidden Waterfall Is Earth’s Largest by Volume

Arctic Ocean’s Hidden Waterfall Is Earth’s Largest by Volume

NOAA-backed research reveals the Denmark Strait cataract, an underwater waterfall beneath the Arctic between Iceland and Greenland, draining cold Nordic Sea water downward at about 3.2 million cubic meters per second (≈123 million cubic feet per second). It’s the world’s largest waterfall by volume, though invisible to ships, and it helps drive the Atlantic Meridional Overturning Circulation, influencing Europe’s climate and marine ecosystems. Warming could weaken or alter this flow, with potential global climate implications.

Forecast Signals a 100% Chance of a Record-Strong El Niño This Year

Forecast Signals a 100% Chance of a Record-Strong El Niño This Year

European forecast models now indicate a 100% chance of a “super” El Niño forming by November, potentially the strongest on record. The pattern is expected to dampen Atlantic hurricane activity while bringing wetter fall and winter conditions to the southern U.S. Atlantic tropical activity is likely below average, though Eastern Pacific activity could rise; the season is forecast to have about 13 named storms and 6 hurricanes, roughly near the seasonal average. Forecasters caution that the most significant effects may not be felt until later in the season, with implications for rainfall and drought relief in the Southeast and Gulf Coast regions.

Record-Setting El Niño Could Redefine 2026 Weather

Record-Setting El Niño Could Redefine 2026 Weather

Models warn of a rare, possibly record-breaking El Niño this summer that could be the strongest since 1877–78, with sea-surface temperatures about 3°C above average by December. If it materializes, New England could see a near-record warm, more humid summer with wetter conditions and more coastal storms, followed by a wetter fall/winter and less snow; the Atlantic hurricane season may be quieter.

Masculine norms tied to bigger climate footprints among wealthy white men

A multi-country study published in Norma: International Journal for Masculinity Studies links masculine norms to larger carbon footprints, driven by travel, meat-heavy diets and high-emission industries, and finds men generally show less concern for climate change and environmental politics than women, though some men are actively working to change these patterns; prior research notes men emit about 26% more pollution than women in transport and food in France, highlighting a gender-based emissions gap.

Tonga Eruption Cooled the Stratosphere and Redrew How We Read the Sky

Tonga Eruption Cooled the Stratosphere and Redrew How We Read the Sky

The January 2022 Hunga Tonga eruption sent roughly 146 teragrams of seawater vapor into the stratosphere, cooling that atmospheric layer by about 0.5–1°C rather than warming it, and leaving no clear imprint on global surface temperatures in 2023–2024. The eruption's depth (about 490 feet below sea level) let magma vaporize seawater and fuel the plume, which reached the mesosphere and generated planetary-scale pressure waves and a Mediterranean meteo-tsunami. The event injected more water vapor than any prior eruption and, because the moisture persists, it is expected to influence atmospheric chemistry into the late 2020s, reshaping how scientists model volcanic impacts on the climate.

Global Drive to Cut Fossil Fuels Takes Center Stage in Colombia

Global Drive to Cut Fossil Fuels Takes Center Stage in Colombia

In Santa Marta, Colombia, ministers and officials from more than 50 countries gather for the First Conference on Transitioning away from Fossil Fuels, urging a rapid shift from oil, gas and coal to cleaner energy for climate action and energy security. The two‑day talks are expected to produce policy proposals rather than binding commitments, with discussions focusing on subsidies reform and financing, while major emitters like the US, China, and India, and oil‑rich Gulf states, are not attending. The conference aims to build political momentum ahead of forthcoming global climate negotiations.

From Frustration to Framework: Global Push to End Fossil Fuels Launches in Colombia

From Frustration to Framework: Global Push to End Fossil Fuels Launches in Colombia

Colombia and the Netherlands host the world’s first Transitioning Away from Fossil Fuels conference in Santa Marta (April 24-29), uniting 54 governments and civil society to outline national roadmaps for phasing out fossil fuels. Not a UN COP and not a binding agreement, the summit aims to coordinate diverse efforts, mobilize finance and debt relief for developing countries, and publish a scientist-led report to guide action as renewables expand and oil prices rise amid geopolitical tensions. Major emitters like China and the US are absent, but the gathering seeks a practical blueprint to accelerate the energy transition despite fossil-fuel inertia and potential climate tipping points.

Georgia wildfires destroy 120 homes, triggering evacuations across counties

Georgia wildfires destroy 120 homes, triggering evacuations across counties

Wildfires in Georgia—and related blazes in Florida—have destroyed about 120 homes in Georgia and forced evacuations as crews battle dozens of fires under hot, dry conditions. A Florida firefighter died amid the outbreak, and forecasters say it will take substantial rainfall (roughly 8–10 inches over time) to curb the blazes, with precipitation expected to be below average through July.
