Global heating has already set back farming around the world, and wiped out seven years of steady advance.

Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders.

The UK’s new plan to control immigration has alarmed human rights groups. A Latin American example could offer hope instead.

Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in the water are small and stunted. Many are dead

Earth’s atmosphere is a remarkably thin layer of gases that sustain life. The diameter of Earth is 12,742km and the atmosphere is about 100km thick. If you took a model globe and wrapped it up, a single sheet of tissue paper would represent the thickness of the atmosphere.

It is really hard to know how a species is doing by just looking out from your local coast, or dipping underwater on scuba

By the century’s end, longer summers could last for almost half the year − probably a bit too much for many of us.

The tropical water at the equator is renowned for having the richest diversity of marine life on Earth, with vibrant coral reefs and large aggregations of tunas, sea turtles, manta rays and whale sharks.

We’re all going to die. This is the repeated warning about climate change in some media: if we don’t change our ways we face an existential threat. So why haven’t we got a policy solution in place?

If you’ve ever been seasick, “stable” may be the last word you associate with the ocean. But as global temperatures rise, the world’s oceans are technically becoming more stable.

Some of the ocean’s top predators, such as tuna and sharks, are likely to feel the effects of rising carbon dioxide levels more heavily compared other marine species.

Take today’s heat, apply mathematical logic and consider a murderously hot future, 56°C by 2100, for hundreds of millions.

Just over 60 years ago, a giant wave washed over the narrow inlet of Lituya Bay, Alaska, knocking down the forest, sinking two fishing boats and claiming two lives.

 If a warming world becomes a drier one, how will the green things respond? Not well, according to a new prediction.

Wildfires have become one of the most potent symbols of the threats posed by global warming, and images of fire are widely used to illustrate climate change news stories.

As bushfires continue to burn around Australia, smoke has continued to blanket major cities and regional areas.

In the aftermath of Australia’s devastating Black Summer fires, research has begun to clarify the role of climate change.

Of an estimated 228 million cases of malaria worldwide each year, around 93% are in Africa. This proportion is more or less the same for the 405,000 malaria deaths globally.

Global heating may be to blame for the fact that Europe has grown drier over the last 2,000 years to a new high in 2015.

As the tides rise ever higher, the world’s coastal cities carry on sinking. It’s a recipe for civic catastrophe

The destruction of tropical forest is a major contributor to biodiversity loss and the climate crisis. In response, conservationists and scientists like us are debating how to best catalyse recovery of these forests. How do you take a patch of earth littered with tree stumps, or even a grassy pasture or palm oil plantation, and turn it back into a thriving forest filled with its original species?

The problem, at least in terms of public health, is that it was not actually a sandstorm. It was a dust storm.

As ever, the poorest people will most feel the heat in a hotter world. But a green growth initiative could help them.
