Sea level rise to dramatically speed up erosion of rock coastlines by 2100
Rock coasts, which make up over half the world's coastlines, could retreat more rapidly in the future due to accelerating sea level rise. This is according to new research led by Imperial College London and supported by researchers from the University of Glasgow. The researchers modelled likely future cliff retreat rates of two rock coasts in the UK, based on forecasts of sea level rise for different greenhouse gas emissions and climate change scenarios.

Working with mountain communities could help water systems adapt to climate
Imperial scientists have shared how working directly with mountain communities could drive adaptation to the loss of their main water sources. Nearly two billion people globally rely on mountain water for drinking and irrigation, but this water source is under threat due to global heating. Mountainous regions are particularly impacted by the effects of the climate crisis , with melting glaciers and snow adding to water scarcity in regions such as the Himalayas, Central Asia, and Andes.

Rethinking mountain water security
Water security in mountain regions relies on an understanding of the interlinks of water supply and demand that goes far beyond the study of glacier melt. Current information on how the communities which depend on water from mountain snow and ice will be affected by climate change is limited, according to new research published in Nature Sustainability.

Science sleuths solve century-old mystery of Martian meteorite’s discovery
A toxin which makes pigs vomit is the surprising key which has unlocked the century-old mystery of the origins of a Martian meteorite, and the possible identity of the Black student who discovered it. In 1931, an unusual stone stored in the geological collection of Purdue University in the USA was identified as a pristine example of a meteorite - a piece of space rock blasted from the surface of Mars millions of years ago before being pulled into the Earth's atmosphere.

Dynamic oxygen levels may have accelerated animal evolutioná
Oxygen levels in the Earth's atmosphere are likely to have -fluctuated wildly- one billion years ago, creating conditions that could have accelerated-the development of early animals, say researchers. Scientists believe atmospheric oxygen-developed in three stages, starting with what is known as the Great Oxidation Event-around two billion years ago, when oxygen first appeared in the-atmosphere.

Super eruptions are millions of years in the making - followed by rapid surge
New research suggests that super-eruptions occur when huge accumulations of magma deep in the Earth's crust, formed over millions of years, move rapidly to the surface, disrupting pre-existing rock. Researchers from the Scottish Universities Environmental Research Centre (SUERC) and the University of Bristol led an international team of scientists to make the discovery using a model for crustal flow.

No signs (yet) of life on Venus
The unusual behaviour of sulphur in Venus- atmosphere cannot be explained by an -aerial- form of extra-terrestrial life, according to a new study. Even if -our- Venus is dead, it-s possible that Venus-like planets in other systems could host life Paul Rimmer Researchers from the University of Cambridge used a combination of biochemistry and atmospheric chemistry to test the -life in the clouds- hypothesis, which astronomers have speculated about for decades, and found that life cannot explain the composition of the Venusian atmosphere.

Scientists provide explanation for exceptional Tonga tsunami
Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year. In a new paper , an international team including researchers from Cardiff University say the exceptional event was caused by acoustic-gravity waves (AGWs) triggered by the powerful volcanic blast, which travelled into the atmosphere and across the ocean as the Hunga Tonga-Hunga Ha'apai volcano erupted.

Scientists explain why Uranus and Neptune are different colours
Layers of haze particles are responsible for the different blue hues of the ice giants Neptune and Uranus. Neptune and Uranus have much in common - they have similar masses, sizes, and atmospheric compositions - yet Neptune looks distinctly bluer than its planetary neighbour Uranus. New research led by Professor Patrick Irwin, Department of Physics , University of Oxford suggests that a layer of haze that exists on both planets is behind the different hues of blue.
