Hunting High Sea Levels in South Africa

Along the coast of South Africa, researchers explore ancient rock formations dating to a period about 120,000 years ago when the earth was warmer and sea level was higher than today, trying to find clues and determine just how high the oceans might rise in a warmer world.

The Making of Antarctica’s Hidden Fjords

Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago. Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise.

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.

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.

Islands Want UN To See Climate As Security Threat

The Marshall Islands and other low-lying island nations appealed to the U.N. Security Council to recognize climate change as an international security threat that jeopardizes their very survival.
