Ocean floor mud reveals secrets of past European climate

Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe's climate has changed over the past 3000 years.

Wave beams mix and stir the ocean to create climate

Ocean circulation patterns have a profound effect on global climate. Waves deep within the ocean play an important role in establishing this circulation, arising when tidal currents oscillate over an uneven ocean bottom. ...

Could climate change shut down the Gulf Stream?

The 2004 disaster movie "The Day After Tomorrow" depicted the cataclysmic effects—superstorms, tornadoes and deep freezes— resulting from the impacts of climate change. In the movie, global warming had accelerated the ...

Antarctic bottom waters freshening at unexpected rate

In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world's oceans. Over the last decade, scientists have been ...

Seals help plug Antarctic water mystery

Elephant seals have helped scientists to demonstrate that fresh water from Antarctic's melting ice shelves slows the processes responsible for the formation of deep-water ocean currents that regulate global temperatures.

Acquiring ice measurements from space

The satellite age has revolutionised our understanding of Earth, giving us accurate information to help critical agreements on climate change such as at the current COP21 conference in Paris. Diminishing polar ice is one ...

When did the Andes mountains form?

The Andes have been a mountain chain for much longer than previously thought, new research from the University of Bristol, UK suggests.

Scientists identify climate 'tipping points'

An international team of scientists have identified potential 'tipping points' where abrupt regional climate shifts could occur due to global warming,
