The cold, remote Arctic Ocean and its surrounding marginal seas have experienced climate change at a rate not seen at lower latitudes. Warming air, land and sea temperatures, and large declines in seasonal Arctic sea ice cover are all symptoms of the changing Arctic climate. Although these changes are occurring in relatively remote locations, there is growing evidence to link Arctic sea ice retreat to increasingly erratic weather patterns over the northern hemisphere.

This summer, wildfires erupted in California, torrential rains flooded parts of Japan, and record-breaking temperatures led to a number of heat-related deaths around the globe. Disasters like these are augmented by climate change, and scientists say extreme weather like this will increase and worsen as climate change accelerates. And it’s impacting our mental health.

Hurricane Harvey, with its historical amount of rainfall over Texas, followed by a string of Hurricanes Irma, Jose and Katia in the North Atlantic basin in 2017, has triggered longstanding questions about any linkage between hurricanes and climate. Can we really blame these recent hurricanes on climate changes? Or are they simply a coincidence of nature happening once every few decades, similar to the triple of Hurricanes Beulah, Chloe and Doria back in 1967?

Renewable energy is increasingly inevitable, and those that dominate the markets in these new technologies will likely have the most influence over the development patterns of the future. As other major powers find themselves in climate denial or atrophy, China may well boost its power and status by becoming the global energy leader of tomorrow.

The Turnbull government’s flagship energy plan, the National Energy Guarantee, was intended to end a decade-long stalemate on energy and climate policy in Australia. Ironically, since its unveiling in October 2017, the debate has heightened considerably, with the result that the government has now walked away from the emissions-reduction component of the policy.

In Colombia’s coffee-producing region of Risaralda, small trees run along the sharp incline of the Andes Mountains, carefully tended in tidy rows. Thousands of green coffee berries turn brilliant red as they ripen, ready to be harvested by hand. The steep hills here prevent mechanized techniques.

To cool the world and also boost plant growth, geo-engineered crops might do the trick. But if they work by dimming the sunlight, the plants will suffer. Proposals to tackle climate change that rely on geo-engineered crops show neatly the double bind that can await remedies which try to do too much.

A climate scientist talks to a psychologist about coping with the crushing stress related to climate change. Here’s what he learned.

We developed a new prediction system we call PROCAST (PROabilistic foreCAST), and used it to predict the natural variability of the climate system. This refers to how the climate varies naturally from warm to cool phases that last a few years at a time, and is separate from the long-term trend of anthropogenic global warming. PROCAST predicts a warm phase for the next few years.

Local people collect water from a muddy waterhole in 2006 in San Marcos Tlacoyalco. The Tehuacan Valley South-East of Mexico City has long experienced severe water shortages. Drought and climate change have contributed to this but recent industrial growth has also strained the very limited ground water resource. Water resources in the area are largely based on a weekly delivery by truck as well as collecting water from small pools known as Jagueys.

Now it's so hot in Europe that dogs are having to wear shoes. While a nice sunny day may seem like the perfect time for a stroll with your pet pooch, Swiss police are urging dog owners to cover their pets' paws.

Global warming isn’t the cause of slowdown in a huge circulation pattern in the Atlantic Ocean, which is, in fact, part of regular, decades-long cycle that will affect temperatures in coming decades, according to a new study.

A more strategic approach to urban growth can ensure our cities maintain adequate green space and become low-carbon, efficient and affordable.

New research asks a big question: Is there such a thing as a sustainable civilization, perhaps one that lies far beyond our own galaxy? Or are all civilizations doomed to destroy themselves?

More people than ever are acutely aware that rising levels of carbon dioxide (CO₂) in the atmosphere are accelerating climate change and global warming.

Every March, glacier “watchers” take to the skies to photograph snow and ice clinging to high peaks along the length of New Zealand’s Southern Alps.

I am afraid my message is going to be controversial. You see, I think there are deep problems with the standard climate change narrative, which has equated "green" with carbon reduction.

Australia is a continent defined by extremes, and recent decades have seen some extraordinary climate events. But droughts, floods, heatwaves, and fires have battered Australia for millennia. Are recent extreme events really worse than those in the past?

The targets set in the Paris Agreement on climate change are ambitious but necessary. Failure to meet them will lead to widespread drought, disease and desperation in some of the world’s poorest regions.

Almost every climate scientist agrees human-caused climate change is a major global threat. Yet, despite efforts over the past 30 years to do something about it, emissions keep increasing.

Scientists have known for a long time that as climate change started to heat up the Earth, its effects would be most pronounced in the Arctic.

Megacities are on the rise. There are currently 47 such areas around the globe, each housing more than 10 million residents.

In 2016, more renewable energy was added to the global grid than ever before, and at a lower cost. A global energy revolution is clearly underway. What catalysed this transformation?

Far from protecting U.S. interests, the tariffs are bound to stifle the current solar boom, destroying American jobs and dragging down clean energy innovation. As economists who research climate and energy policies that can foster a greener North American economy, we argue the government should instead create targeted subsidies that support innovation and lower costs across the supply chain.

Science fiction writers can’t seem to agree on the rules of time travel. Sometimes, as in Doctor Who, characters can travel in time and affect small events without appearing to alter the grand course of history.

Land degradation can take many forms, but always entails a serious disruption of a healthy balance between five key ecosystem functions.

On Campbell Island in the Southern Ocean, some 400 miles south of New Zealand, is a single Sitka spruce. More than 170 miles from any other tree, it is often credited as the “world’s loneliest tree”.

You don’t need a supercomputer to predict how the weather above your head is likely to change over the next few hours – this has been known across cultures for millennia. By keeping an eye on the skies above you, and knowing a little about how clouds form, you can predict whether rain is on the way.

If recent trends continue for another two years, the global share of electricity from renewables excluding hydropower will overtake nuclear for the first time.

Imagine then an enlightened “quantitative easing” transferring resources not to banks, but to mobilise a rapid transformation in energy infrastructure, retrofitting existing buildings, decarbonising transport and constructing zero-carbon power stations.

For every 10 degrees north from the equator you move, spring arrives about four days earlier than it did a decade ago, a new study suggests.

In the 2015 Paris Agreement on climate change, nearly every country on Earth pledged to keeping global temperatures “well below” 2C above pre-industrial levels and to “pursue efforts to limit the temperature increase even further to 1.5C”.

Much of the public discussion about climate science consists of a stream of assertions. The climate is changing or it isn’t; carbon dioxide causes global warming or it doesn’t; humans are partly responsible or they are not; scientists have a rigorous process of peer review or they don’t, and so on.

The seas will continue to rise for 300 years. That’s the conclusion of a new study, published in Nature Communications, which projects how much the sea level will rise under varying degrees of success in tackling climate change right up to the year 2300.

Agroforestry could play an important role in mitigating climate change because it sequesters more atmospheric carbon in plant parts and soil than conventional farming, report researchers.

Imagine a world where every country has not only complied with the Paris climate agreement but has moved away from fossil fuels entirely. How would such a change affect global politics?

Most of us have a range of white goods (refrigerators, washing machines, etc.) in our homes. These white goods provide a host of benefits, but they also have significant environmental impacts, and it’s important to consider these when using and choosing white goods.

For the first time, the European Union generated more electricity from wind, solar and biomass than from coal in 2017, according to new analysis from two thinktanks.

If you read or listen to almost any article about climate change, it’s likely the story refers in some way to the “2 degrees Celsius limit.” The story often mentions greatly increased risks if the climate exceeds 2°C and even “catastrophic” impacts to our world if we warm more than the target.

When fires, floods and other major disruptions alter natural areas, our first instinct is to restore what’s lost. But moving forward may mean leaving some treasured things behind.

The Trump administration, and its allies in Congress, are fighting a losing war. They continue to press forward for the development of oil, gas, and coal when the rest of the world understands the implication of that folly. Global warming is the most pressing issue for our time.

A program of one of the five largest supermarket chains in South Africa, drove increased adoption of environmental practices at the farm level, a new study of the store’s supply chain indicates.

Last night I cooked my family a delicious pasta dinner using biogas energy. This morning we all had eggs cooked on biogas. I’m not sure what’s for dinner tonight, but I know what will provide the energy for cooking

Damage from extreme weather events during 2017 racked up the biggest-ever bills for the U.S. Most of these events involved conditions that align intuitively with global warming: heat records, drought, wildfires, coastal flooding, hurricane damage and heavy rainfall.

Climate change will not affect every place equally. Here’s what seven regions in the bull’s eye are doing about it now.

Many scientists have found evidence that climate change is amplifying the impacts of hurricanes. For example, several studies just published in December 2017 conclude that human-induced climate change made rainfall during Hurricane Harvey more intense. But climate change is not the only factor making hurricanes more damaging.

To maintain our capacity to address climate change, we need to recognize and address the trauma it creates.

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.

Beef gets a bad press, environmentally speaking. We’re bombarded with reports highlighting its high carbon footprint accompanied by images of belching cows and devastated rainforests.

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.

When asked about major threats to their country, Europeans are more likely than Americans to cite global climate change, according to a recent Pew Research Center survey.

Robert Jay Lifton was born 91 years ago. Living through the catastrophes of the 20^th century — world war, tyrannical regimes, genocide, the nuclear bomb, terrorism — he grappled with their terrible impact on human beings. His work as a psychiatrist, historian and public intellectual forged his reputation as one of the world’s foremost thinkers. 

Researchers have found at least eight occurrences of iron penetrating the Pacific Ocean, with each occurrence likely associated with global climate change over thousands of years.

The largest wildfire ever recorded in Greenland was recently spotted close to the west coast town of Sisimiut, not far from Disko Island where I research retreating glaciers.

By virtue of its size, elevation and currently frozen state, Greenland has the potential to cause large and rapid increases to sea level as it melts.

When utility executives make decisions about building new power plants, a lot rides on their choices.

By continuing to delay significant reductions in greenhouse gas emissions, we risk handing young people alive today a bill of up to US$535 trillion.

Solarpunk imagines a sustainable future, and what it might be like to live in it. Solarpunk’s optimism towards the future is the first concept that needs complicating here.

Our worry is that putting too much emphasis on the climate overlooks the role of political and socio-economic factors in determining a community’s vulnerability to environmental stress.
