Climate crisis

The climate crisis demands action — and action is happening. This archive tracks real progress: policy wins, clean-energy milestones, community resilience, and scientific advances that show meaningful change is possible. Stories here come from every corner of the world.

Solar panels, for article on Africa renewable energy capacity

Africa nearly tripled new renewable capacity in 2025

African countries added 11.3 gigawatts of renewable energy capacity in 2025, nearly triple the 4.2 GW added in 2024, according to the International Renewable Energy Agency.The shift reaches deeper than capacity numbers. Of 322 energy projects announced across Africa last year, 253 were renewable — 173 of them solar — while only 22 were natural gas. The economics, as one Kenyan climate finance lead put it, have “decisively turned in favor of clean energy.”The biggest remaining obstacle isn’t technology. It’s financing — African countries face borrowing costs up to three times higher than wealthy nations, owing to political and economic risk premiums that no amount of falling solar prices can erase on their own. Closing that gap could determine whether this momentum reaches the communities who need power most.

Birdsong and chimp drumming suggest carbon financing is helping Sierra Leone’s forest

Carbon financing in Sierra Leone’s Gola Rainforest is doing more than locking away carbon — it’s bringing the forest back to life, according to a new study in Conservation Science and Practice. Researchers recorded audio at 133 sites and found the protected park’s dawn chorus was measurably richer than the community forest right next door, with the shift happening sharply at the border. The idea, drawn from the acoustic niche hypothesis, is that more species means more sound frequencies filled, like instruments in an orchestra each holding a lane. It’s one of the first direct signs that REDD+ programs, long sold on climate grounds, may genuinely shelter biodiversity too — a hopeful nudge for how the world funds living forests everywhere.

New York City’s first urban forest plan targets its hottest, least-shaded blocks

New York City’s first Urban Forest Plan aims to grow tree canopy from 23.4% to 30% of the city’s surface by 2040, with a focus on neighborhoods that have been left in the sun for too long. Right now, environmental justice communities sit under about 19% canopy cover, while wealthier areas enjoy 26% — a gap you can feel on a hot summer afternoon. The plan protects existing trees, expands planting on streets and private land, and trains residents, including NYCHA tenants, to care for the urban forest. It’s a hopeful reminder that shade, cooler air, and cleaner streets are infrastructure every neighborhood deserves.

Clean energy holds China’s emissions flat for two years without an economic slowdown

China’s CO2 emissions have now stayed flat or declining for 21 straight months — a first in modern history, and one that’s happening while the economy keeps growing. New analysis from Carbon Brief estimates emissions dipped 0.3% in 2025, as a 43% surge in solar generation and a 14% rise in wind together absorbed nearly all the year’s added electricity demand. Even more striking, China added 75 gigawatts of battery storage — outpacing peak demand growth and weakening the long-standing case for new coal plants. If this pattern holds, the world’s largest emitter may be quietly showing every country what it looks like when clean energy stops chasing demand and starts outrunning it.

U.N. General Assembly backs landmark World Court ruling on nations’ climate obligations

Climate accountability took a historic leap forward when the UN General Assembly voted 141 to 8 to endorse a landmark International Court of Justice ruling that treats climate action as a legal obligation rather than a political choice. The resolution, drafted by the Pacific island nation Vanuatu after years of patient advocacy, affirms that states breaching their climate duties may be required to halt the harm and offer reparation. Secretary-General António Guterres called it a victory for the planet, noting that the path to justice runs through a swift, equitable shift to renewables. For frontline communities everywhere, this reframing matters: climate protection is no longer just good policy — it’s a right they can claim.

Electric concrete mixers are booming in China, hitting 70% of new sales

Electric concrete mixers are quietly rewriting what “hard to electrify” really means — and in China, they’re on track to make up roughly 70% of new mixer sales in 2025, up from under 2% just four years earlier. The reason is refreshingly simple: these trucks return to the same batching plant every shift, so charging infrastructure can live right where the work begins and ends. In early 2026, Chinese buyers chose pure electric over hydrogen almost unanimously, signaling that batteries have won this corner of heavy transport. Trials are now spreading to the U.K., Germany, Switzerland, Norway, and Australia. The bigger lesson for climate progress: electrification advances fastest not by tackling the hardest routes first, but by recognizing where the work is already bounded enough to make the switch obvious.

India hits 150 GW of solar capacity after fastest quarter on record

India’s solar power capacity has crossed 150 GW, with a remarkable 6.65 GW installed in March 2026 alone — one of the strongest single months the sector has ever seen. The growth spans rooftops, sprawling utility-scale farms, and off-grid systems now powering remote communities that the main grid has yet to reach. Behind the numbers are falling panel costs, smart policy choices, and a country choosing to meet rising electricity demand without leaning harder on fossil fuels. With India’s Paris Agreement goal of 500 GW of non-fossil capacity by 2030 now well within sight, this milestone shows that the world’s most ambitious clean energy transitions are no longer aspirational — they are unfolding in real time.

Switzerland begins work on the world’s most powerful redox flow battery

A redox flow battery rising from a 27-meter pit in northern Switzerland will become the world’s most powerful, capable of running 210,000 homes for a full day once it comes online in 2029. Unlike the lithium-ion batteries in our phones, this one stores energy in two liquid electrolytes pumped through a membrane — a design that’s non-flammable, almost fully recyclable, and built to cycle indefinitely without wearing out. It can respond to grid swings in milliseconds, soaking up excess wind power and releasing it when nearby AI data centers need a steady surge. Projects like this hint at what a renewables-first grid actually looks like: not just cleaner generation, but storage patient and powerful enough to make wind and solar genuinely dependable.

U.K. solar generation hits record 15 GW as gas falls to historic low

Britain’s electricity grid hit 98.8% zero-carbon power for a half-hour stretch on April 22, 2025, with gas squeezed down to just 1.2% of the mix. A day later, solar set its own new peak at 15.4 gigawatts, and wind had broken records just weeks before. The shift is striking when you zoom out: renewables made up 3% of Britain’s electricity in 2000, and 44% by 2025. As one of the world’s largest economies shows that running a national grid on almost entirely clean power is genuinely workable, it offers a glimpse of what energy security and climate progress can look like together — and a roadmap others can follow.

France launches plan to ditch all fossil fuels by 2050

France just became the first country to set hard deadlines for ditching every fossil fuel: coal by 2030, oil by 2045, and gas by 2050. The roadmap was unveiled at a conference in Santa Marta, Colombia, where roughly 60 nations gathered to share their own transition plans after a global agreement stalled at COP30 last November. What makes France’s plan unusual isn’t a single bold target but the fact that it draws one clear line across all three fuels, covering everything from power plants to home heating to transport. As climate envoy Benoît Faraco noted, almost no other country has named an end date this clearly. In a moment of energy anxiety worldwide, naming the destination is itself a quiet act of leadership.
