Climate Change Is Likely to Make Air Travel a Lot Bumpier

Not only is the extent of sea ice coverage in the Arctic shrinking, but the ice that remains is also becoming thinner.

Thinning Arctic Ice Is Breeding Dangerous Phytoplankton Blooms

Coral reefs are dying across the world, and the biggest of them all - Australia's Great Barrier Reef - is undergoing a second major bleaching event in two years.

Tiny Plastic 'Nurdles' Are Invading the Shores of British Beaches

Sea ice in the Arctic continues to experience record-low levels, with both extent and thickness on track to break winter-minimum records over the coming weeks, and thicker, older ice becoming extremely rare.

Scientists Hatch a Plan to Refreeze the Arctic, Saying Cutting CO2 Isn't Enough

It's no secret that Earth has undergone numerous convulsive changes in its history, from mass extinctions and climatic changes to cataclysmic collisions and long-term periods of immense volcanic eruptions - or multiple combinations of the above.
