Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and died.

The “tragedy of the horizons,” a term coined by Canada’s Mark Carney, governor of the Bank of England, has been haunting the financial sector ever since climate change began posing serious threats to the planet.

Delhi’s air pollution crisis made international headlines in early December when a cricket match between India and Sri Lanka was suspended due to poor air quality.

Overall 2017 will be the warmest non-El Niño year on record globally, and over the past 12 months we have seen plenty of extreme weather, both here in Australia and across the world.

Variety is not just life’s spice, but its support system. But it may not be so simple for mixed forests, researchers say.

The East Antarctic ice sheet could raise sea levels far more than anyone thought. But there’s no way of knowing the worst for 40 years yet.

Growing up in the south-west of the USA, I lived through the severe drought of the late 1970s. Then, drinking water at restaurants was given only on demand, and my eyes would burn from the smoke of regional forest fires. The nights were balmy, even in November.

After dodging the worst of Hurricane Irma, Florida’s coastal real estate boom shows no signs of slowing.

Wildfires tearing across Southern California have forced thousands of residents to evacuate from their homes. Even more people fled ahead of the hurricanes that slammed into Texas and Florida earlier this year, jamming highways and filling hotels.

Many observers of China’s escalating global program of foreign investment and infrastructure development are crossing their fingers and hoping for the best.

Even before this year’s devastating hurricane season, the team of demographers I work with at Penn State and the Puerto Rico Institute of Statistics had predicted that the population of Puerto Rico would decline over the next few decades.

In August 2016, a third of the residents of the North Island township Havelock North fell acutely ill with gastroenteritis after their water was contaminated with campylobacter.

Humans are probably contributing more methane to the atmosphere through fossil fuel use and extraction than scientists previously believed, report researchers.

More than 95% of people still eat meat and don’t like being told that it is wrong and bad for the planet to do so. But it is now well established that meat production is responsible for a substantial proportion of human greenhouse gas emissions, not to mention issues around animal welfare. 

Around the globe, about 815 million people – 11 percent of the world’s population – went hungry in 2016, according to the latest data from the United Nations. This was the first increase in more than 15 years.

Melting of Antarctica’s ice can trigger rapid warming on the other side of the planet, according to our new research which details how just such an abrupt climate event happened 30,000 years ago, in which the North Atlantic region warmed dramatically.

Some aspects of climate change could benefit certain forms of agriculture in the Northeastern United States, new research suggests—though the researchers caution that there are many variables in the future scenario they envision.

Microbes in permafrost that eat sun-weakened carbon and convert it into carbon dioxide may be providing a major pathway for the greenhouse gas to enter the atmosphere, new research suggests.

People in northern China have a reduced life expectancy when compared with people living in the south due to higher concentrations of air pollution, a new study suggests.

A new study outlines some of the effects that climate change will have on northern cities with cold climates, including in Europe and the North America.

There has been no let up since Hurricane Harvey dumped record-breaking rains on the Houston area of Texas. Hurricane Irma lashed parts of the Caribbean and Cuba and devastated the Florida Keys and the state’s west coast.
