Message in a frozen bubble: Antarctic ice reveals abrupt rises in atmospheric CO2 in the ancient past

Today's atmospheric carbon dioxide (CO2) levels are higher than ever during at least the last 800'000 years. More importantly, the atmospheric levels of this greenhouse gas continue rising at a speed that is unparalleled in our planet's recent geological history. Intensifying extreme weather events and... click to read more

Networking between marine protected areas help sustain fisheries

Fisheries have an important impact on ocean health, but what if we could protect our oceans and eat it too. Setting aside ocean areas for marine conservation helps preserve marine habitats and biodiversity, but can also help sustain fisheries. No-take zones that prohibit fishing activities are... click to read more

Ice production on the hottest planet in our solar system

Water is crucial to life on Earth. It is also present on other planets and solar system bodies. Indeed, ground-based radar observations and space probe data indicated the presence of frozen water ice even on Mercury, the hottest planet in our solar system! Water, in... click to read more

How rain sculpts mountains

The shape of Earth's surface can tell us a lot about what kinds of natural events have happened in a region and when. Heavy rainfall, for instance, causes rivers to swell, which can force a river to erode faster into its bed. This connection between... click to read more

Using satellites to look for floating plastics in the ocean

Plastics in the marine environment pose a significant threat to marine life. Macroplastics entering ocean waters have two fates - floating on the surface, or sinking. If not removed by clean-up operations, they may harm or even kill marine life through entanglement or ingestion, and/or... click to read more
