Megacity traffic soot contributes to global warming Soot from road traffic in emerging countries can reach high altitudes, where it can be transported over long distances and thus contributes to global warming. The reduction of pollutants from road traffic such as soot particles from diesel cars should the

The long dry: why the world's water supply is shrinking A global study has found a paradox: our water supplies are shrinking at the same time as climate change is generating more intense rain. And the culprit is the drying of soils, say researchers, pointing to a world where drought-like conditions will become
Climate change imperils Midwest ag production A new Cornell University-led study shows that Midwest agriculture is increasingly vulnerable to climate change because of the region's reliance on growing rain-fed crops.
Scientists identify new minerals for carbon capture Research confirms new minerals are capturing and storing carbon in a new paper by University of Alberta geologists and their collaborators. The minerals, members of the hydrotalcite group, are the first outside of the carbonate family to naturally capture
How will the winds of climate change affect migratory birds? Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers from the Cornell Lab of Ornithology came to this concl
A glimmer of hope for the world's coral reefs The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a study published today in Nature Climate Change, the response of the Great Barrier Reef to extreme temperatures in 2017 was m

How will addressing climate change affect the job market? The Paris Agreement's goal to keep global warming below 2°C can be achieved by increasing the use of renewable energy and improving energy efficiency. A new International Labour Review study explores the impact of such transitions on employment.
Wind power vulnerable to climate change in India The warming of the Indian Ocean, caused by global climate change, may be causing a slow decline in wind power potential in India, according to a new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Harvard C
Inactivating genes can boost crop genetic diversity Researchers from CIRAD and INRA recently showed that inactivating a gene, RECQ4, leads to a three-fold increase in recombination in crops such as rice, pea and tomato. The gene inhibits the exchange of genetic material via recombination (crossover) during
Global warming increases frost damage on trees in Central Europe Global warming increases frost damage on trees in large areas of Central Europe, according to a new Finnish-Chinese study. Late frost damages are economically important in agriculture and forestry. In certain years, they are known to have caused losses am
Greenhouse gas 'detergent' recycles itself in atmosphere: NASA study A simple molecule in the atmosphere that acts as a 'detergent' to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research. Understan
Climate change risks 'extinction domino effect' New research reveals the extinction of plant or animal species from extreme environmental change increases the risk of an 'extinction domino effect' that could annihilate all life on Earth.This would be the worst-case scenario of what scientists call 'co-
Food webs essential for nature conservation efforts in the future Nature conservation should not focus on individual species but on whole food webs, because the protection of their functioning is important for the predictability of species, especially when global warming is increasing environmental variability.
Steroid synthesis discovery could rewrite the textbooks Steroids are essential molecules for life in all complex organisms such as animals and plants. Researchers from the VIB-UGent Center for Plant Systems Biology, the University of Technology Sydney Climate Change Cluster and the University of Queensland hav
Human ancestors not to blame for ancient mammal extinctions in Africa New research disputes a long-held view that our earliest tool-bearing ancestors contributed to the demise of large mammals in Africa over the last several million years. Instead, the researchers argue that long-term environmental change drove the extincti
The shifting role of cities in addressing global climate change In recent years, cities have asserted themselves as relevant actors in efforts to address global climate change. The announcement by the United States of their intent to withdraw from the Paris Agreement has generated more attention than ever for what cit
Study predicts decreasing brown bear habitat due to climate change A recent analysis of data related to the brown bear (Ursus arctos) estimates that suitable habitat will be reduced by 11 percent across Central Asia and the Asian Highlands by 2050 due to climate change, predominantly due to the changes in temperature and
Volcanoes and glaciers combine as powerful methane producers Large amounts of the potent greenhouse gas methane are being released from an Icelandic glacier, scientists have discovered.A study of Sólheimajökull glacier, which flows from the active, ice-covered volcano Katla, shows that up to 41 tonnes of
Google data shows public interest in conservation is rising The public's interest in conservation is rising. Based on an adapted version of Google Trends -- which tracks user searches on Google -- the results show that people search for conservation just as often as they do for climate change.
Ocean warming New research has uncovered a previously unaccounted for pathway transporting heat from the Pacific Ocean to the Indian Ocean, and even further to the Southern Ocean, which surrounds Antarctica. It has implications for climate change and what we know about
Affordable catalyst for CO2 recycling A catalyst for carbon dioxide recycling, Mineral pentlandite may also be a conceivable alternative to expensive precious metal catalysts. This is the result of a study conducted by researchers from Ruhr-Universität Bochum (RUB), Fritz-Haber Institute
Climate simulations project wetter, windier hurricanes New supercomputer simulations by climate scientists at Lawrence Berkeley National Laboratory have shown that climate change intensified the amount of rainfall in recent hurricanes such as Katrina, Irma, and Maria by 5 to 10 percent. They further found th
Carbon goes with the flow Many people see the carbon cycle as vertical -- CO2 moving up and down between soil, plants and the atmosphere.However, new Michigan State University research published in the current issue of Geophysical Research Letters, adds a dimension to the vertical
Simulation versus observation As an indicator of the impacts of climate change, Arctic sea ice is hard to beat. Scientists have observed the frozen polar ocean advance and retreat at this most sensitive region of the Earth over decades for insight on the potential ripple effects on as
Rising sea levels may build, rather than destroy, coral reef islands Rising global sea levels may actually be beneficial to the long-term future of coral reef islands, such as the Maldives, according to new research published in Geophysical Research Letters.Low-lying coral reef islands are typically less than three metres
Global warming has never stopped in the past hundred years The global warming has never stopped in the past hundred years, with maximum rate of change after Second World War II and almost constant rate during the latest three decades. The hiatus is merely a decadal balance between global warming and the cooling r
