A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.

Prototype helps researchers find patterns from many large datasets.

Tsunami waves battered the coasts of several Tongan islands and ash blankets everything.

To learn how ocean water is melting glaciers, NASA’s Oceans Melting Greenland mission extensively surveyed the coastline of the world’s largest island.

Two researchers from the University of Ottawa are the first to map out all the glaciers that end in the ocean in the Northern Hemisphere and provide a measure of their rate of change over the last 20 years.

The Labrador Sea between Canada and Greenland is often referred to as a ‘lung of the deep ocean’ because it is one of only a handful of locations worldwide where oxygen from the atmosphere can enter the deepest layers of the ocean. 

For many, an ideal forest is one that looks the same as it did before European colonizers arrived. 

If you had to guess which part of the world has the highest levels of atmospheric mercury pollution, you probably wouldn’t pick a patch of pristine Amazonian rainforest. Yet, that’s exactly where they are.

When rain falls, it picks up pollution from streets, farms and other manmade features as it winds toward the ocean.

Research paper describes how scientists from Europe and the US are working together to better track permafrost carbon dynamics.
