Freezing rain is a typical weather disaster in winter and early spring over many regions of the world, even tropical areas. It develops as supercooled water (below 0 °C) in the air and freezes immediately after depositing on cold surfaces. In southern China, freezing rain mainly happens in the m ...
Alongside climate change, air pollution is one of the biggest environmental threats to human health. Tiny particles known as particulate matter or PM2.5 (named for their diameter of just 2.5 micrometers or less) are a particularly hazardous type of pollutant.
How do coastal channels form and what are their stable configurations? These are the questions a team of researchers, including a University of Arkansas assistant professor of geosciences, John Shaw, set out to answer in a recent paper.
University of Canterbury researchers have published the world's first study confirming the discovery of microplastics in fresh snow in Antarctica.
They may be tiny, but they pose a global problem for humans and the environment: microplastic particles. These are plastic particles with a diameter between one micron and five millimeters.
Using state of the art sensor technologies, experts at the University of Nottingham have found that calves reared on farms not only vary significantly in their movement and space patterns, but also that some calves are more predictable in their behavior compared to others.
A new dataset featuring hundreds of satellite images of whales has been published to support the development of artificial intelligence systems which will aid crucial conservation work.
Rutgers researchers have discovered that nitrogen-fixing bacteria hidden within leaf cells could lead to more efficient and sustainable methods of crop cultivation.
As the cherished rainforest in South America's Amazon River region continues to shrink, the river itself now presents evidence of other dangers: the overexploitation of freshwater fish.
Oceans and coastlines have been subjected to human use for centuries. But the effects of human activity on the oceans are now more extensive, with the resulting changes happening more rapidly than ever before.
Polychaetes are segmented worms that live in nearly all marine habitats, from the shallow seashore or estuaries to the deep sea. They are very abundant, often making up as much as 70% of the animals found in an area. Not only are there many of them, but they are very important in contributing to ...
Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms that determine how big an organism can grow?
There are already plenty of mosquitoes in Australia. They bring pest and public health risks to many parts of the country. Now a new species of mosquito, Aedes shehzadae, has been discovered 90 years after the first (and only other observation) of it in Papua New Guinea—and it's thanks to citize ...
The list of bird species found in Nepal has now grown to 891, after a bird never before seen in the country was spotted at a national park in the south.
A new study has confirmed what biologists have long suspected: that tropical birds are much more colorful than their temperate peers.

The second phase of the Saint-Laurent Biodiversity Corridor has been selected by Ville de Montréal to be one of the 5 additional projects of the participatory budget after the first 7 projects that had been chosen in September 2021. This development will be part of the project entitled "Zones no ...
When we see our spectacular blue planet from space, we see no borders. We see no separation between our climate and nature, or nature and people. We see only our single, fragile shared home in the vastness of space.
Research led by the University of Southampton has revealed that an abrupt change in climate conditions in the North Atlantic around 800 years ago played a role in a decline in Atlantic salmon populations returning to rivers. Subsequent human exploitation of salmon combined to reduce their popula ...
Oceans play an important part in combatting climate change, which is why they must be protected. "The oceans are helping us fight climate change because they absorb a lot of heat and carbon dioxide in the atmosphere," explains Jackie Savitz, Chief Policy Officer for North America at Oceana, whic ...
Annual convening of governments, civil society recognizes the ocean’s important role in climate action. The ocean has a critical role to play in stabilizing the Earth’s climate, absorbing 90% of excess heat and 40% of human-made carbon dioxide emissions.
Trente ans après la signature de la Convention sur la diversité biologique des Nations unies, le portrait est plus sombre que jamais, mais plusieurs tentent toujours de lutter contre le déclin de la biodiversité. Le Devoir a discuté du sujet avec la secrétaire exécutive de la Convention, Elizabe ...
Singapore says it is facing a dengue "emergency" as it grapples with an outbreak of the seasonal disease that has come unusually early this year.
World Bank President David Malpass on Tuesday defended the bank's work on climate change and said U.S. Treasury officials had been "overwhelmingly supportive" of the bank and its staff in public and private in recent months.
Fires across the West are threatening water supplies for millions of people—particularly in areas hard hit by climate change, like California.
Located around 1,600 kilometers off the coast of East Africa, the Seychelles is an ecological paradise. But as climate change is affecting every region around the world, small island developing states are among the most vulnerable to the impacts such as increased temperatures and sea level rise.
Solar panels need to be deployed over vast areas worldwide to decarbonize electricity. By 2050, the United States might need up to 61,000 square kilometres of solar panels — an area larger than the Netherlands1. Land-scarce nations such as Japan and South Korea might have to devote 5% of their l ...
New research is examining the impact of climate change on migratory Atlantic salmon. Scientists in Scotland and Canada are working on the study
The UNDP, the EU, and the government of Sweden have been working through the Cambodia Climate Change Alliance to support the country in developing multi-sectoral plans with concrete and ambitious commitments to the global climate agenda.
The European Union (EU) delegation to Jamaica has underscored its commitment to continue helping the island to implement measures that will lessen the possibly devastating impact of climate change.
Climate negotiators crave a return to “normality” when global warming dominated the agenda — but war, hunger and disease overshadowed the beginning of talks in Bonn, Germany Monday.
For almost a year, climate scientists have sounded one clear message. The world’s totemic goal of holding average global temperature rises to 1.5°C is still technically within our grasp, but will slip without a dramatic course correction by humanity.
Nations must not lose hope and focus in tackling global warming despite the many obstacles to international co-operation, the UN climate chief said on Monday at the start of a 10-day meeting in Bonn, Germany.
Scientists welcome "honest conversation" about the long standing threat of sea level rise driven by climate change, warning coastal protection measures cannot save all communities, even if the Environment Agency could afford them everywhere.
The 6th National Report to the Convention on Biological Diversity is the most comprehensive analysis yet of the country’s biodiversity, with more than 100 experts from different fields contributing to the effort.
Scientists have now confirmed that a certain well-known tree in Southeast Asia is actually two species, not one. Indigenous people in Borneo, however, have known this all along.
An invasive species of acid-spraying ant is spreading throughout Australia, causing concern it could wipe out small native species and make homes impossible to sell.
All countries including Ireland need to scale up ambition and actions to halt global biodiversity loss, according to Elizabeth Maruma Mrema, executive secretary of the UN Secretariat of the Convention on Biological Diversity.
It was a banner moment at COP26, one of the climate summit’s headline achievements. On stage, U.K. Prime Minister Boris Johnson sat with President Félix Tshisekedi of the Democratic Republic of Congo as the two put their pens to paper.
Botanists are working on an ambitious project to restore 1 million hectares (2.5 million acres) of degraded land in South Africa that were previously covered by thickets of the indigenous succulent spekboom (Portulacaria afra).
Generally, the word pollution conjures images of billowing smokestacks, oily water and trash-filled highway medians. But for whales, dolphins and porpoises, a subtler and perhaps more sinister source of pollution also poisons their realm: human-made sound.
An estimated 45 million women make up 40 per cent of the workforce in small-scale fisheries worldwide. But they are left out of decision-making processes when it comes to the access and use of fisheries and coastal resources.
Global food systems are at a breaking point. Not only are they responsible for roughly a quarter of global greenhouse gas emissions, they are also the top contributors to water pollution and biodiversity collapse.
After epic floods in India, South Africa, Germany, New York and Canada killed hundreds in the past year, droughts are now parching landscapes and wilting crops across the western US, the Horn of Africa and Iraq.
From the red-eared slider turtle, cockatoo and falcon to the yellow-cheeked gibbon, capuchin monkey and orangutan, nothing is too much for those demanding unusual pets in India.
With every passing week, it looks more like a cover-up. The repeated mass strandings of crabs and lobsters on the coast of north-east England, and the ever less plausible explanations provided by the government, are the outward signs of an undersea disaster and a grim new politics.
The climate crisis may lead the human race to shrink in size, as mammals with smaller frames appear better able to deal with rising global temperatures, a leading fossil expert has said.
Climate change is slowing down the conveyor belt of ocean currents that brings warm water from the tropics up to the North Atlantic. Our research, published today in Nature Climate Change, looks at the profound consequences to global climate if this Atlantic conveyor collapses entirely.
Flying over Antarctica, it's hard to see what all the fuss is about. Like a gigantic wedding cake, the frosting of snow on top of the world's largest ice sheet looks smooth and unblemished, beautiful and perfectly white. Little swirls of snow dunes cover the surface.
About 20 years ago, Bala Chaudhary worked in conservation and habitat restoration in California. Her job was to design plans for creating new habitats for endangered species out of degraded or disturbed land. In her work, she kept coming up against one persistent challenge—reinstating soil micro ...
