Delvewire's coverage of Climate: in-depth, with context and evidence.

Soviet planners knew that taking the Aral Sea's rivers for cotton would shrink the fourth largest inland body of water on earth, and judged the water worth more in the fields. By 2011 it had lost 92 per cent of its volume. A 13 kilometre dike brought one corner back in two years, and kept the rest dry.

Around half the nitrogen in your body was fixed in a factory. The reaction that does it consumes about two per cent of all the energy humanity uses and emits roughly 450 million tonnes of carbon dioxide a year, and India spends more on subsidising its product than on almost anything else in the budget.

At 16:52 on a Friday the control room running Britain's electricity was holding enough spare power to survive losing its single biggest generator. Eighty-three seconds later it had lost nearly twice that, and 1,152,878 customers had been cut off deliberately. About 500 megawatts of the shortfall came from generators nobody had dispatched, switching themselves off to stay safe.

The longest continuous record of what the air is made of has been running since March 1958 on the side of a Hawaiian volcano. It has stopped three times in sixty eight years: once because the money ran out, twice because of lava.

In December 2015, nearly 200 countries stood up in a conference hall outside Paris and agreed, for the first time, to fight climate change together. It was hailed as the moment the world finally got serious. A decade on, global emissions are higher than the day it was signed, one American president has pulled the country out of it twice, and the UN's own scientists say the promises currently on the table still add up to a planet roughly three degrees warmer. Here is what the Paris Agreement actually promised, and why almost none of it happened the way it was supposed to.

The ice loss is real, measured and accelerating. The image everyone carries, of water closing over a skyline, is not what the projections say. The sea has risen about twenty centimetres since 1901 and is expected to add somewhere between a third of a metre and about a metre by 2100, which drowns no cities but does something less cinematic and more expensive. And in the one megacity genuinely going under, the sea is the smaller half of the problem.

The top of the Matterhorn is African rock sitting on the floor of an ocean that no longer exists. The top of Everest is a shallow seabed with trilobites in it. Neither of those is a figure of speech. Both mountains are what happens when two continents meet and neither is heavy enough to sink, and the ranges they made went on to change the weather for the rest of the planet.

A patch of the Pacific Ocean warms up by a degree or two, and the whole planet's weather shifts. Here is what El Niño actually is, why it keeps returning, what forecasters expect in 2026, and what the last one did.

Everyone knows that NASA's satellite saw the ozone hole years early and its software threw the readings away. It did not. The flag was doing exactly what it was built to do, and the reason it took another year is more interesting.
