Armadas of Icebergs May Not Be the Cause of Cooling in the North Atlantic

Armadas of icebergs were probably not the cause of abrupt episodes of cooling in the North Atlantic over the past 440,000 years, according to new research published today in Nature.

Researcher Develops Models of Marine Microbes to Understand Global Climate Change

Dip a beaker into any portion of the world’s oceans, and you’re likely to pull up a swirling mix of planktonic inhabitants. The oceans are teeming with more than 5,000 species of phytoplankton — microscopic plants in a kaleidoscope of shapes and sizes. Together, phytoplankton anchor the ocean’s food chain, supplying nutrients to everything from single-celled organisms on up to fish and whales.

Rapid Climate Change Affected Marine Ecosystems Tens of Thousands of Years Ago

In common parlance, the phrase "global climate change" is often used to describe how present-day climate is changing in response to human activities. But climate has also varied naturally and sometimes quite rapidly in the past, with implications for the ocean and its ecosystems.

Huge Reservoir of Methane Discovered in Deep Fram Strait of the Arctic Ocean

Methane, a highly effective greenhouse gas, is usually produced by decomposition of organic material, a complex process involving bacteria and microbes.

Anthropogenic Carbon Dioxide Entering the Atmosphere Underpins Greenhouse Effect

Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be the for the very long term, thousands of years.

Study: Ocean Acidification Caused the Earth's Greatest Mass Extinction

Changes to the Earth's oceans, caused by extreme volcanic activity, triggered the greatest extinction of all time, a study suggests.

German Marine Scientists Reconstruct Variations in Past Arctic Climate

In the past decades ferromanganese crusts have been the focus of interest due to their resource potential of valuable metals such as cobalt, nickel or rare earth elements, which are highly enriched in these crusts. For the moment, however, the cost of underwater mining outweighs their cost of recovery.

Gradual, Prolonged Release of Greenhouse Gases from Arctic Permafrost Soils

A new scientific synthesis suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions, which may afford society more time to adapt to environmental changes, say scientists in an April 9 paper published in Nature.

Soil May Be Releasing Carbon Dioxide to the Atmosphere Faster Than Believed

Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought, according to Oregon State University soil scientists.
