US scientists think the effect clouds have on global warming may be underestimated. New research shows that clouds block sunlight and reflect radiation back to space, impeding the rate of global warming. But for how long?

Ice ages on Earth used to occur at intervals of every 40,000 years. But at a point about a million years ago, ice age intervals switched to every 100,000 years.

The common wisdom about climate change is that it’s too big and too abstract for humans to comprehend, that it’s too hard to talk about. But it turns out many people are having tangible experiences of our changing environment.

It’s not just the planet that benefits from reductions in carbon dioxide and other greenhouse gases that intensify global warming.

Dedicated surfers, deeply involved with monitoring the natural coastal environment around the world, warn that climate change now poses a major threat to this booming leisure industry.

Some farmers have turned to less chemically-intensive techniques to reduce the negative impact of agriculture, such as organic farming, which has been shown to outperform conventional farming by many standards of environmental sustainability. The question is whether we can meet the demand for food, which is predicted to rise substantially in the next 50 years.

International scientists say global warming could double the frequency of the extreme La Niña weather phenomenon that triggers floods and hurricanes.

Despite robust global economic growth over the past two years, worldwide carbon emissions from fossil fuels grew very little in 2014, and might even fall this year.

Is the Anthropocene real? That is, the vigorously debated concept of a new geological epoch driven by humans.

Scientists say tens of thousands of glaciers are melting faster than ever − and many will continue to do so even if climate change can be stabilised.

Innovative turbines designed in the UK aim to harness tidal energy to produce cheaper electricity − without endangering marine life.

China is by far the world’s biggest producer of solar panels, but the industry could become a victim of its own success.

A supplement added to the feed of high-producing dairy cows reduces methane emissions by 30 percent—with no negative effect on milk production.

There are many ongoing signs that the planet is heating up, even “on fire.” In the western region of North America, the prolonged drought has led to high temperatures and many wildfires, from Canada and the Northwest earlier this summer to California more recently.

You may have read recent reports about huge changes in sea level, inspired by new research from James Hansen, NASA’s former Chief Climate Scientist, at Columbia University. Sea level rise represents one of the most worrying aspects of global warming, potentially displacing millions of people along coasts, low river valleys, deltas and islands.

Canadian province cancels a successful project which rewarded people for generating renewable energy.

The UK still sees nuclear power as a way of combating climate change, but the massive costs mean it is struggling to get new reactors built.

A poll conducted in 119 countries reveals the factors that most influence climate change awareness and risk perception for 90 percent of the world’s population.

Writing recently on The Conversation, Clive Hamilton correctly pointed out that an emissions trading scheme (ETS) can in no sense be called a tax – the two are fundamentally different.

There’s a mystery inside trees upon which the fate of coastal cities, threatened by rising sea levels from climate change, may depend. Each year, the Earth’s forests take up about one-quarter of the carbon dioxide emitted by humans, effectively slowing the speed and severity of global warming.

People cannot engage in something they cannot see or feel. We need concrete reasons to care and act. In this way, climate change presents a threefold intangible challenge:

Flooding is a well-known natural hazard along the US coastline. Nearly 40% of the US population resides in its coastal counties.

Hydraulic engineers in Norway aim to use surplus power from wind and sun to cut the need for fossil fuel plants to boost European electricity supplies.
