The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape.

L’augmentation des niveaux de CO2 atmosphérique actuelle est 10 fois plus rapides qu’à tout moment au cours des 50 000 dernières années.

A new study led by researchers at the University of Oxford has used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results, published today in the journal Science, could help to identify species most at risk today from human-driven climate change.

Le débat sur les nouveaux OGM est biaisé par les lobbies qui défendent toute une série d’intérêts économiques. A la faveur de sa présidence européenne, la Belgique doit se positionner dans ce dossier en facilitant l’élaboration d’une politique européenne qui donne la priorité à l’équité, à l’autonomie des agriculteur.e.s, à la santé publique et à l’environnement.

Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluster of Excellence for climate research CLICCS. Since 2007, conditions in the Arctic have shifted, as confirmed by data recently published in the journal Communications Earth & Environment. Between 2007 and 2021, the marginal zones of the Arctic Ocean experienced 11 marine heat waves, producing an average temperature rise of 2.2 degrees Celsius above seasonal norm and lasting an average of 37 days. Since 2015, there have been Arctic marine heat waves every year.

Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies.

As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Center in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.

A team of Penn State researchers investigated how seeing frightening news about climate change day after day may shape the way people feel about the phenomenon and how willing they are to take action to address it. They published their findings in the journal Climatic Change. 

Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests. The paper, published in the journal Nature Sustainability, is entitled "Quantifying the Human Cost of Global Warming."

Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows. Paramecium bursaria contain algae that live inside their cells and provide energy by photosynthesis. The results of a NEW STUDY showed a 50% decline in net photosynthesis—a major impact on the algae's ability to produce energy and release oxygen

A comprehensive new study led by Professor Gwen Robbins Schug at UNC Greensboro traces the impact of rapid climate change events on humans over the past 5,000 years and offers lessons for today's policymakers. The meta-analysis of approximately a decade's worth of bioarchaeology data was published today as a Proceedings of the National Academy of Sciences perspective article by a team of 25 authors representing 21 universities.

An international team of scientists painstakingly gathered data from more than 50 years of seagoing scientific drilling missions to conduct a first-of-its-kind study of organic carbon that falls to the bottom of the ocean and gets drawn deep inside the planet.

All students at the University of Barcelona will have to take a mandatory course on the climate crisis after the establishment agreed to meet the demands of activists conducting a sit-in occupation. The announcement came after a seven-day occupation by a group from the anti-fossil fuel organisation End Fossil Barcelona.

In the past 50 years, the oceans have absorbed more than 90% of the excess heat caused by our carbon dioxide emissions, with one ocean absorbing the vast majority.

Global heating could become "catastrophic" for humanity if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed both. The world needs to start preparing for the possibility of a "climate endgame."

Scientists at Scripps Institution of Oceanography at UC San Diego used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades.

As required by the Climate Change Act 2008, the government has today submitted the Third UK Climate Change Risk Assessment (CCRA3) to Parliament. Professor Richard Betts MBE, who led this team, says that ""ne of the key conclusions from the University of Exeter's work was that current worldwide policies could result in up to 4°C warming by 2100."

The accelerating melting of the Himalayan glaciers threatens the water supply of millions of people in Asia, new research warns.

Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated.

Les barrages et les réservoirs représentent les plus grands dangers qui menacent la connectivité des fleuves et rivières à courant libre dans le monde
