History has a way of repeating itself. But unlike science, built on general principles and testable theories about the natural world, history examines past events and human actions using evidence and interpretation.

The changes in Alpine permafrost are mostly invisible but have increasingly significant consequences for mountain regions.

CLIMATE Climate change poses a serious threat to the habitats of the bowhead whale, which may shrink by up to 75 percent by the end of the century, a new projection from the University of Copenhagen shows.

An international study, published in Science, has found that only 24% of present-day glacier mass will remain if the world were to warm to 2.7°C, the trajectory set by current climate policies.

The interdisciplinary NODSSUM mission led by the CNRS in collaboration with a team from Ifremer, the ASNR, and multiple national and international partners 1 will take to the seas on 15th June for one month.

New research from an international group has for the first time shown a strong correlation between the two.

Clean hydrogen could be key to a greener future and there is a lot if it right beneath our feet in the Earth's crust.

A team of archaeologists and scientists led by Karen Hardy, Professor of Prehistoric Archaeology at the University of Glasgow, has discovered evidence for one of the earliest human populations yet known in Scotland.

A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, according to a new modelling study led by UCL researchers. Previously, most research has assumed that the technique, known as stratospheric aerosol injection, would be deployed in the tropics and so would require specially designed aircraft capable of flying at altitudes of 20km or more to inject the particles.

The Reykjanes Peninsula at Iceland's southwestern edge is one of the country's most populated regions, and it is also one of the most volcanically active.

Avalanche bulletin and snow situation When frozen rivers break up in spring, the sudden release of ice and water can reshape river channels and pose serious risks to nearby infrastructure.

According to a study by the University of Bonn, droughts caused the country to rise by six millimeters between 2012 and 2020 South Africa is slowly lifting out of the water - by up to two millimeters per year depending on the region. It had been assumed up to now that this phenomenon was due to mantle flow in the Earth's crust.

Avalanche bulletin and snow situation To enhance biodiversity across aquatic and terrestrial systems, natural areas of high ecological value need to be interconnected. However, the necessary collaboration between different stakeholders is often lacking, particularly in urban areas. This is shown by a new study as part of the Blue-Green Biodiversity research initiative.

An international team, including researchers from UNIGE, has revealed that the Arabian Peninsula's desert was once home to a vast lake and rivers that shaped its landscape. The Empty Quarter (Rub' al-Khali), the vast desert of the Arabian Peninsula, was not always an arid landscape.

What happens when captured CO2 is pumped into the ground? Highly sophisticated computer simulations now make it possible to predict its long-term behaviour.

UCalgary physicist Eric Donovan explains the science behind the night-time illuminations amidst 2025 solar maximum Last year, the night skies treated Calgarians to more auroral displays than usual.

In addition to being the basis of life, water contains a wealth of valuable information about and for humankind.

In the first study to consider the long-term evolution of the rivers that flow beneath glaciers, researchers have new insights into the future of Antarctica's melting ice that may change the way climate scientists predict the effects of a warming planet.

Understanding ice dynamics in the Yukon's St. Elias Mountains to prepare for sea level rise and protect water resources As the world focuses on glacier preservation this UN World Water Day , re

Over the last 150 years, humans have emitted over 2,000 gigatons of carbon dioxide (CO2) into the atmosphere, increasing the CO2 concentration by 50 percent from pre-Industrial Revolution levels.

According to a predictive model developed by a CNRS researcher 1 and his European colleagues, the microalgae present in peat bogs could offset up to 14% of future CO2 emissions, thanks to their photosynthetic activity 2 .

40th anniversary of the Vienna Convention for the protection of the ozone layer The Earth's protective ozone layer is recovering - a success story that started 40 years ago with the Vienna Convention. Global atmospheric measurements are crucial for the regulation and monitoring of ozone-depleting substances.

Imagine a heavy book resting on a table. If you try to gently push the book across the table with the tip of your finger, it may first appear to remain motionless-it needs a lot more force to start sliding visibly. Similarly, if you slowly start tilting the table upward, the book still appears to remain motionless, sticking to the table through friction until the table's tilt reaches some critical angle and the book suddenly slides down.

Industrial wastewater, slurry, microplastics and heavy metals-the list of pollutants that end up in water bodies is long.

Waste generated by human activities has now reached the deepest point in the Mediterranean: the 5,112-metre-deep Calypso Deep in the Ionian Sea.

By weakening the North Atlantic overturning circulation, the ocean absorbs less carbon dioxide - resulting in consequential costs and further warming of the climate The ocean is the largest CO2 reservoir on earth.

A weakening of the North Atlantic overturning circulation would cause the ocean to absorb less carbon dioxide - this is associated with economic costs and the climate continues to heat up In Brief Hi

The Fraser River is unique among the world's great rivers - a huge, relatively natural, undammed, mountain river running through a dense urban area.

Glaciers are melting around the world. Last decade, the loss of ice in the more populated regions, such as Europe, increased at ever-faster rates.
