Migratory Behavior of Oceanic Sharks Revealed

As the nations of the world prepare to vote on measures to restrict international trade in endangered sharks in early March, a team of researchers has found that one of these species, the oceanic whitetip shark, regularly crosses international boundaries.

Uneven Global Sea-Level Rise Predicted

Scientists have known for some time that sea level rise around the globe will not be uniform, but in this study researchers show in great detail the global pattern of sea-level rise that would result from two scenarios of ice-loss from glaciers and ice sheets.

Thawing Permafrost: Huge Factor in Global Warming

Thawing permafrost is emitting more climate-heating carbon faster than previously realised. Scientists have now learned that when the ancient carbon locked in the ice thaws and is exposed to sunlight, it turns into carbon dioxide 40 percent faster.

Reduced Sea Ice Disturbs Balance of Greenhouse Gases

The widespread reduction in Arctic sea ice is causing significant changes to the balance of greenhouse gases in the atmosphere. This is shown in a new study conducted by researchers from Lund University in Sweden, among others.
