California’s drought underscores the need to improve how the state — and the rest of us — divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit.

A world with more people will see more competition for food. Many of our competitors may not be human, because natural pests are spreading far and wide.

As South America’s biggest city suffers its worst drought in over a century, São Paulo state politicians are putting re-election prospects ahead of the need to introduce measures to address a desperate situation for millions of people.

The chance that the southwestern United States will experience a decade-long drought sometime in the next century is at least 50 percent, researchers say. Further, there is a 20 to 50 percent chance of a “megadrought”—one that could last up to 35 years.

As greenhouse gases raise temperatures in Europe, British researchers warn that the risk is increasing of the arrival of mosquito-borne diseases that kill many thousands of people every year in tropical regions.

The Arctic lost less sea ice this year than last, and that is good news for many polar bears, if not for their preferred prey, the ringed seals.

The combined forces of climate, economic and social change are leaving Spain increasingly exposed to the damaging and costly effects of wildfires.

An international study says warming is affecting not only the Arctic but also the Antarctic – and that could significantly raise global sea levels much faster than previously predicted.

Cool, highland regions of East Africa could be more vulnerable to malaria than previously thought, while population centers in hot, lowland areas could be less vulnerable, according to new fine-scale climate model projections.

Researchers have uncovered key attributes of “brown carbon,” the particles from partially burned wood, that play an important role in warming the atmosphere.

Giant waves in the jet stream that often governs our weather are changing as the Arctic warms more rapidly − leading to long periods of soaring temperatures that pose major threats to economies and human health.

New research supports the growing body of evidence that many past civilisations have collapsed because of climate change. So is history repeating itself?

Wildfires have been blazing on all summer, and the latest of them is occurring in Oregon, near the Columbia River Gorge. Owners of 140 homes have already evacuated, and despite the efforts of 400 firefighters, the flames have continued to spread over five square miles.

Coffee — the black liquid that kick starts the day for billions of people each morning — is one of our most precious global commodities. But as the video above from Royal Botanic Gardens, Kew explains, it’s also under threat from a changing climate.

The speed and scale of China’s rapid economic growth has led to widespread degradation of its densely inhabited coastlines, according to an analysis of 60 years of social, economic and environmental data.

Wildfires and agricultural burning play a much bigger role in climate change and human health than previously thought, new calculations suggest.

Research has highlighted the negative effect acidification of oceans can have on marine life, but now fishing communities are waking up to the big threat it poses to their livelihoods.

New research shows that forest ecosystems are particularly vulnerable to rapid changes in the climate – and have been suffering intensified disturbance in Europe for decades.

Any Montana angler worth a double-haul cast knows that the iconic state fish, the westslope cutthroat trout, has been crowded out by the non-native rainbow trout, first introduced to these rivers by well-meaning sportsmen in the 1880s.

Failure to factor immediate action on climate change into American policies and business plans aimed at economic prosperity will lead to havoc, warns former US Treasury Secretary.

The CO2 which is absorbed by the oceans may cause damage in two ways, researchers say – by making the seas more acidic, and also by adding to atmospheric warming. Researchers in Germany say the carbon dioxide that is absorbed by the world’s oceans may still be damaging the atmosphere – bizarrely, by amplifying the warming caused by the greenhouse gases which are there already.

According to a 2008 report by the federal U.S. Climate Science Program, global warming is likely to result in “increased costs to human health and well being” in the United States.

The odds on food production being unable to meet the needs of an expanding population are hard to predict, but a new study shows that the risk increases dramatically when man-made climate change is factored in.
