The oceans can’t take any more: Fundamental change in oceans predicted

This item was filled under Climate
Our oceans need an immediate and substantial reduction of anthropogenic greenhouse gas emissions. If that doesn't happen, we could see far-reaching and largely irreversible impacts on marine ecosystems, which would especially be felt in developing countries....

Greenhouse gas emissions remain primary threat to polar bears

This item was filled under Climate
Greenhouse gas emissions remain the primary threat to the preservation of polar bear populations worldwide. This conclusion holds true under both a reduced greenhouse gas emission scenario that stabilizes climate warming and another scenario where emissions and warming continue at the current pace, according to updated research models....

What is subsidence?

This item was filled under Facts, Positioning and Geology

Land subsidence is a gradual settling or sudden sinking of the Earth’s surface. This geodetic mark in Louisiana is anchored deep below the ground and was level with the ground when it was originally placed there, but now the ground around the mark has subsided.

Monitoring seawater reveals ocean acidification risks to Alaskan shellfish hatchery

This item was filled under Climate
Ocean acidification may make it difficult for Alaskan coastal waters to support shellfish hatcheries by 2040 unless costly mitigation efforts are installed to modify seawater used in the hatcheries....

Carbon capture and storage safety investigated

This item was filled under Climate
A significant step has been made for potential Carbon Capture and Storage (CCS) deployment, with the publication of the results from the world's first experiment into the realistic simulation of potential environmental impact of a submarine CO2 leakage....

Seafood supply altered by climate change

This item was filled under Climate
The global supply of seafood is set to change substantially and many people will not be able to enjoy the same quantity and dishes in the future due to climate change and ocean acidification, according to scientists....

Ocean algae will cope well in varying climates

This item was filled under Climate
Tiny marine algae that play a critical role in supporting life on Earth may be better equipped to deal with future climate change than previously expected, research shows....

New study reveals mechanism regulating methane emissions in freshwater wetlands

This item was filled under Climate
Though they occupy a small fraction of the Earth's surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research identifies an unexpected process that acts as a key gatekeeper regulating methane emissions from these freshwater environments.The study describes how high rates of anaerobic methane oxidation substantially reduce atmospheric emissions of methane from freshwater wetlands....

Exit dinosaurs, enter fishes

This item was filled under Climate
A pair of paleobiologists have determined that the world's most numerous and diverse vertebrates -- ray-finned fishes -- began their ecological dominance of the oceans 66 million years ago, aided by the mass extinction event that killed off dinosaurs....
