Artificial intelligence could be used to accurately predict tsunamis
A reliable early warning system to detect tsunamis could be a step closer thanks to research from Cardiff University. Researchers say their analysis of ocean soundwaves triggered by underwater earthquakes has enabled them to develop artificial intelligence (AI) that allow prediction of when a tsunami might occur.

'Eyes' of Mars rover get test run on Earth
’Eyes’ of Mars rover get test run on Earth
The capabilities of a UCL-led panoramic camera system that will guide the search for life on Mars atop the European Space Agency's Rosalind Franklin rover are being tested ahead of the rover's launch next year. A replica of the rover and the Panoramic Camera suite known as PanCam are being used to test the wide range of photo settings - from panoramas to close-ups, from 3D maps to wheel selfies - that will deliver the greatest science possible during the ExoMars mission on the Red Planet.

Revealing ecological risks of climate change on global river basins
Rising global temperatures will impact major river basins differently around the world, with rivers in South America, southern Africa and Australia among those most at risk of extreme ecological changes, a new study led by UCL has found. For the first time, researchers from UCL Geography, the University of Nottingham and the UK Centre for Ecology & Hydrology combined large datasets with an environmental flow approach to predict how changes of between 1-3°C in the Earth's temperature would impact 321 of the world's biggest river basins.

Youngest ever lavas dated from the Moon
Researchers at The University of Manchester, have been involved in an international collaboration to analyse the age and history of some of the Moon's youngest lava flows. The rock samples were collected by the Chinese National Space Agency during the robotic Chang'e-5 mission, which marked the first time any nation had collected rocks from the Moon since 1976.

Dinosaurs' ascent driven by volcanoes powering climate change
Dinosaurs’ ascent driven by volcanoes powering climate change
The rise of dinosaurs coincided with environmental changes driven by major volcanic eruptions over 230 million years ago, a new study reveals. The Late Triassic Carnian Pluvial Episode (CPE) saw an increase in global temperature and humidity - creating a major impact on the development of animal and plant life, coinciding with the establishment of modern conifers.

Ancient sea ice core sheds light on modern climate change
Ancient sea ice core sheds light on modern climate change
A 170 m record of marine sediment cores extracted from Adélie Land in Antarctica by the Integrated Ocean Drilling Programme is yielding new insights into the complicated relationship between sea ice and climate change. In a new study published , researchers at the University of Birmingham, have collaborated in an international project to identify how fluctuations in sea ice levels have interconnected with both algae blooms and weather events linked to El Nino over the past 12,000 years.

New class of habitable exoplanets are 'a big step forward' in the search for life
New class of habitable exoplanets are ’a big step forward’ in the search for life
A new class of exoplanet very different to our own, but which could support life, has been identified by astronomers, which could greatly accelerate the search for life outside our Solar System. Hycean planets open a whole new avenue in our search for life elsewhere Nikku Madhusudhan In the search for life elsewhere, astronomers have mostly looked for planets of a similar size, mass, temperature and atmospheric composition to Earth.

Global climate report ’wake-up call for all governments to take climate change seriously’
Climate change is already widespread, rapid, and intensifying, according to a new report released today by the UN's Intergovernmental Panel on Climate Change (IPCC), involving contributions from UCL academics. The report, which assesses the physical science behind climate change, highlights that changes in the Earth's climate have already been observed in every region of the globe and across the whole climate system - including the atmosphere, oceans, rivers and lakes, and land - many of which are unprecedented.

Earth's interior is swallowing up more carbon than thought
Earth’s interior is swallowing up more carbon than thought
Scientists from Cambridge University and NTU Singapore have found that slow-motion collisions of tectonic plates drag more carbon into Earth's interior than previously thought.

Arrival of land plants changed Earth’s climate control system
The arrival of plants on land about 400 million years ago may have changed the way the Earth naturally regulates its own climate, according to a new study led by researchers at UCL and Yale. The carbon cycle, the process through which carbon moves between rocks, oceans, living organisms and the atmosphere, acts as Earth's natural thermostat, regulating its temperature over long time periods.

Ear to the ground: Locating elephants using ground vibrations
Ear to the ground: Locating elephants using ground vibrations
Researchers from the , Mpala Research Center and Save the Elephants, have used a combination of acoustic microphones and seismometers to locate elephants. In this novel study, published today in The Journal of the Royal Society Interface , researchers managed to accurately determine elephant locations by measuring the vibration of the ground caused by their rumbles, which are low frequency calls.

Rock crystals from the deep give microscopic clues to earthquake ground movements
Microscopic imperfections in rock crystals deep beneath Earth's surface play a deciding factor in how the ground slowly moves and resets in the aftermath of major earthquakes, says new research involving the University of Cambridge.

New research brings age of 65m-year-old meteorite impact into sharper focus
New research into one of the most volatile periods in Earth's geological history has narrowed down the precise age of a meteorite impact in the Ukraine around 65 million years ago, ruling out the chance that it contributed to the extinction of the dinosaurs but offering new insight into the planet's climate history.

Scientists track veil of toxic metals carried in Kilauea’s gas plumes, revealing hidden dangers of volcanic pollution
A team of volcanologists who observed the colossal 2018 eruption of Kilauea, Hawai'i, have tracked how potentially toxic metals carried in its gas plumes were transported away from the volcano to be deposited on the landscape.

Greenland glacial meltwaters rich in mercury
Greenland glacial meltwaters rich in mercury
New research shows concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding raising questions about the effects of glacial melting in an area that is a major exporter of seafood. "There are surprisingly high levels of mercury in the glacier meltwaters we sampled in southwest Greenland," said lead author Jon Hawkings, a postdoctoral fellow at Florida State University and the GFZ German Research Centre for Geosciences.

Fibre-optics help create most detailed picture of Greenland Ice Sheet
Scientists have used a fibre-optic sensor passed deep into a borehole to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world’s second-largest ice sheet, as the effects of climate change continue to accelerate.

’Stressed’ trees share resources to overcome environmental challenges
A length of steel pipe and a heart monitor are the unlikely tools underpinning new research which suggests that trees may work together to form resource-sharing networks, helping the group collectively overcome environmental challenges. The findings, laid out in a paper published today in Communications Biology, offer fresh insight into how forests around the world might adapt to the increasing environmental stresses of climate change.
