Each year, the Arctic region goes through an annual health checkup — and the results are in: From a rapid decline in snow cover to an unprecedented late season melting event to another year of seabird die-offs, the Arctic has once again shown clear symptoms of an ailing planet.
As the US and Europe worked for decades to reduce air pollution for the sake of public health and the planet, scientists found an unintended and challenging consequence: an increase in tropical storms in some regions.
While species are and will be affected everywhere by climate change, those already living in a warm climate will reach their tolerance threshold faster.
Humans have degraded or destroyed roughly two-thirds of the world's original tropical rainforest cover, new data reveals – raising alarm that a key natural buffer against climate change is quickly vanishing.
Tropical regions with rich evolutionary histories, such as Amazonia, Northern Andes, central American jungles, sub-Saharan Africa and south-eastern Asia, are also treasure troves of genetic diversity within species.
A small increase in water temperature near a Japanese nuclear power plant allowed tropical fish to colonise the area, suggesting global warming will drastically alter some marine ecosystems.
