The weather might seem like it creates weeks of dreary, grey drizzle. But it can also put on a truly sensational – and, often, deadly – show. But what explains these explosive events?

We regularly hear about how El Niño events raise the temperature across much of the planet, contributing to spikes in global average temperature such as the one witnessed in 1998, with severe bush fires, droughts and floods.

Producers and retailers of everything from toilet paper to homes want you to believe that their product is “green”. More are “greenwashing” their products. Greenwashing is the misleading claims of environmental benefits...

Electricity generation is a significant consumer of water: it consumes more than five times as much water globally as domestic uses

In shouting “system change not climate change”, young people understand that the 3-4℃ warmer world we’re headed for would be far more painful, costly and disruptive than any short-term costs or inconvenience we face from taking rapid, bold action.

Climate plans are the order of the day in the presidential primary campaign because carbon pollution is a global threat of unique proportions.

Almost 200,000 Californians have been ordered to evacuate as ferocious winds drove several wildfires near Los Angeles, San Francisco and elsewhere. Many fear they may yet again return to a home ravaged by fire.
