Engineers investigating impact of krill swarms on ocean mixing, and possibly global climate



Scientists have long chalked up ocean mixing of salt, heat, nutrients and gases, such as oxygen and carbon dioxide, to wind...

This video discusses the impact of human activities on the Earth's environment. It covers topics such as deforestation, air pollution, depletion of the ozone layer, and global climate change. The video also highlights the ways...

This video provides an introduction to El Nino and La Nina, two climate patterns in the Pacific Ocean. It explains how these patterns occur, their impacts on global weather patterns, and discusses whether 2021 and 2022 are El Nino or La...

When Geologist Jeff Donnelly of the Woods Hole Oceanographic Institution (WHOI) hunts for hurricanes, he does it safely at ground level, or just slightly below. He is even able to do it without having to encounter so much as a drop of...

We’re in the middle of a rapid, unprecedented, and world-changing increase in the intensity and scale of human activity on this planet.

What will happen to the planet if climate change melts what's left of Arctic permafrost? Shedding light on this overlooked threat, Arctic geologist Sue Natali reveals the true danger of heating up the iciest place on the planet: the...

A massive new study has just been released showing that human activities are threatening Earth’s other life forms in some very bad ways. One million species may be at risk of extinction. Just let that sink in. Isn’t the Anthropocene...

Investing in green energy, holding large corporations accountable for their pollution, stopping pipeline and oil extraction initiatives -- these are non-negotiable actions to protect the planet, but they are still just the bare minimum,...
