Global warming and ocean acidification are threatening marine organisms, such as corals, bryozoans, molluscs, sea urchins or crustaceans, that build their skeletons and shells with calcium carbonate (chalk) according to a new study published this week in the journal Ecography.

The idea that climate change and geological events can shape evolution isn’t a new one: anyone who’s heard of dinosaurs knows that a big change in the environment (like, say, a meteor hitting the Earth 66 million years ago and causing a chain reaction of storms, earthquakes, cold, and darkness) can dictate how animals live, die, and evolve. 

Dormant strains of bacteria that have previously adapted to cope with certain temperatures are switched back on during climatic change, according to a report published today in eLife.

As increased warming in Antarctica causes glaciers to retreat and shed their increasingly-unstable shelves, towering walls of ice are left looming high above the sea.

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and climate impacts.

An interdisciplinary team of researchers at Worcester Polytechnic Institute (WPI) has developed a potential breakthrough in green aviation: a recipe for a net-zero fuel for planes that will pull carbon dioxide (CO2) out of the air.

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated a new technique, modeled after a metabolic process found in some bacteria, for converting carbon dioxide (CO2) into liquid acetate, a key ingredient in “liquid sunlight” or solar fuels produced through artificial photosynthesis.

This year’s Chesapeake Bay “dead zone” was the 10th-smallest observed since 1985, according to findings released today by the Chesapeake Bay Program and its partners, including the University of Michigan.

A decade ago, scientists on a NASA-sponsored ocean expedition found massive populations of phytoplankton blooming beneath sea ice in the Arctic Ocean.

When pandemic-related lockdowns grounded planes and brought car traffic to a near standstill in early 2020, transport emissions plummeted, leading to a drop in levels of a short-lived gas that scrubs methane from the atmosphere.
