Scientists say the answer is in the ice. Scientists know that sea levels have risen more in some places during the past century than in others.

Is your morning coffee an espresso or a skinny latte? Is it from a darkly roasted French or Italian blend?

The kind of hot, dry conditions that can shrink crop yields, destabilize food prices, and lay the groundwork for devastating wildfires are increasingly striking multiple regions simultaneously as a result of a warming climate, according to a new study.

Hopes for fewer large wildfires in 2018, after last year’s disastrous fire season, are rapidly disappearing across the West.

Drought, crop failure, storms, and land disputes pit the rich against the poor, and Central America is ground zero for climate change. Guatemala, Honduras, and El Salvador lie in the trajectory of the so-called “dry corridor” of Central America that stretches from Southern Mexico to Panama. This epithet is a recently adopted description of the region, to describe the droughts that have risen in intensity and frequency over the last 10 years.

Museums, archaeological sites and historical buildings are rarely included in conversations about climate change, which tend to focus on the wider impact and global threats to our contemporary world. Yet these threats impact everything, from local cultural practices to iconic sites of outstanding universal value. In light of this, it’s worth exploring the relationship between our heritage and the changing global climate in more detail.

As part of the Paris Agreement on climate change, the international community committed in 2015 to limit rising global temperatures to “well below” 2C by the end of the 21st century and to “pursue efforts to limit the temperature increase even further to 1.5C”.

Persistent weather conditions, including dry and wet spells, that have increased in the United States may be a result of rapid Arctic warming, according to a new study.

Contrary to stereotypes of young generations being narcissistic or complacent, researchers say both groups are united in concerns about the future of the environment.

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?

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.

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?

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.
