How accurate are the weather models that predict thunderstorms?

The forecast is sunny, but there’s a slight chance of chaos.

Corals can suffer from nutrient imbalance

Improving water quality could help save coral reefs.

Climate change and the modern polar bear

Polar bear evolution holds clues for past climate change events.

Coral bleaching causes deadly competition among fish

Some fish turn aggressive when they have to share limited resources.

The wolverine relies on snow to refrigerate its food. Image: Shutterstock

Wolverines not as invincible as the fictional character

A warmer climate could have devastating effects on the wolverines food supply.

Some species will suffer from climate change while others will thrive — it all depends on their interactions with other species.

Stalagmites form when water containing calcium carbonate drips down onto the floor of a cave and leaves limestone behind when it evaporates. Image: Shutterstock/ Dumitrescu Ciprian-Florin

What stalagmites tell us about climate change

Cave formations can act as prehistoric weather stations.

Seagrass meadows also provide vital habitat for marine species. Image: Shutterstock/Rich Carey

Endangered seagrasses can store carbon

Scientists estimate that seagrass meadows can store as much carbon as a forest.

Sauropods would have contributed as much as 520,000 million kilograms of greenhouse gasses to the Mesozoic atmosphere each year. Image: Shutterstock

Dinosaur farts could have contributed to global warming

Gaseous emissions from giant herbivores may have been enough to warm the Earth.

Polar bears are much older than we thought

Polar bears have actually been around for five times longer than previous studies suggested.
