Climate models disagree on why temperature 'wiggles' occur

Most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. They also provide inconsistent explanations o...

3-D view of Greenland Ice Sheet opens window on ice history

Scientists using ice-penetrating radar have created 3-D maps of the age of the ice within the Greenland Ice Sheet. The new maps will aid future research to understand the impact of climate change o...

Ocean could hold key to predicting recurring extreme winters

New reserch may help to predict extreme winters across Europe by identifying the set of environmental conditions that are associated with pairs of severe winters across consecutive years. Pairs of ...

Arctic ice cap slides into the ocean

Satellite images have revealed that a remote Arctic ice cap has thinned by more than 50 metres since 2012 -- about one sixth of its original thickness -- and that it is now flowing 25 times faster....

New research re-creates planet formation, super-Earths and giant planets in the laboratory

New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, document...

Doubt cast on global firestorm generated by dino-killing asteroid

Pioneering new research has debunked the theory that the asteroid that is thought to have led to the extinction of dinosaurs also caused vast global firestorms that ravaged planet Earth. Scientists...

Fossils survive volcanic eruption to tell us about the origin of the Canary Islands

The most recent eruption on the Canary Islands – at El Hierro in 2011 – produced spectacularly enigmatic white “floating rocks” that originated from the layers of oceanic sedimentary rock u...

Two lakes beneath the ice in Greenland, gone within weeks

Researchers discovered craters left behind when two sub-glacial lakes in Greenland drained away -- an indication that the natural plumbing system beneath the ice sheet is overflowing with meltwater...

Death of a dynamo: A hard drive from space

Hidden magnetic messages contained within ancient meteorites are providing a unique window into the processes that shaped our solar system, and may give a sneak preview of the fate of the Earth's c...

Researchers introduce macrosystems approach to study stream ecology

The Stream Biome Gradient Concept is a way to compare streams in different climates and different continents. The concept can improve how researchers study streams worldwide. "This model will help ...
