On 13 March, a group of teenagers filed a climate-change case before the constitutional court of South Korea. The country ranks as the sixth-largest emitter of carbon dioxide, per capita, in the Organisation for Economic Co-operation and Development. The plaintiffs claimed that their rights had been violated by their government.…

The kilometres-thick ice sheet that covers Greenland shrank by a record amount in 2019, and contributed about 40 percent of the rise in global sea levels, according to a new scientific study.  The huge melt was due not only to warm temperatures but also atmospheric circulation patterns that have become…

With the western United States and northern Mexico suffering an ever-lengthening string of dry years starting in 2000, scientists have been warning for some time that climate change may be pushing the region toward an extreme long-term drought worse than any in recorded history. A new study says the time…

As human activity shapes Earth's climate, animals must increasingly adapt to new environmental conditions. The thermoneutral zone -- the ambient temperature range in which mammals can maintain their body temperature without expending extra energy -- is a key factor in estimating a species' ability to survive in a warming world.…

When it interacts with clouds, oceans and the sun's radiation, it has an overall impact on our planet's living systems, affecting everything from weather and rainfall to global warming.…

A new Columbia Engineering study shows that increased water stress--higher frequency of drought due to higher temperatures, is going to constrain the phenological cycle: in effect, by shutting down photosynthesis, it will generate a lower carbon uptake at the end of the season, thus contributing to increased global warming.

Recent phenomena such as the mass bleaching of the Great Barrier reef suggest heat-related die-off is already occuring in places Global warming will cause "catastrophic" biodiversity loss across the world if greenhouse gas emissions aren't curbed, with some ecosystems liable to collapse as soon as 2030, according to new research…
