NASA Evaluates Impact of Climate Change on Arctic Vegetation

The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover – much of it Arctic tundra – is looking more like landscapes found in warmer ecosystems.

Study Links Perceptions of Climate Change to Infrastructure

Irrigation systems designed to buffer farmers from the effects of a warming planet may be causing them to think their local area is cooler and wetter than it is, says research published June 1 in the journal Global Environmental Change -- perceptions that other studies suggest may slow their efforts to address climate change.

Methane Seeps and Hydrothermal Vents Emerging as Major Force in Ocean Ecosystems

Hydrothermal vents and methane seeping on to the ocean floor was once believed to be biological and geologic oddities. However, they are now considered as a key factor in marine life, global climate, and ecosystems.

Study Results Provide New Insights into Arctic Ocean Methane

Methane gas released from the Arctic seabed during the summer months leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate gas rising up through the sea reaches the atmosphere.

Natural Processes can Provide Solution to Excess Carbon Dioxide Threatening the Planet

Climate scientists have long recognized the importance of forest conservation and forest regrowth in climate mitigation and carbon sequestration -- capturing carbon dioxide (CO2) from the atmosphere. But the detailed information required to make accurate estimates of this potential has remained elusive.
