Why the Mediterranean is a climate change hotspot

Wed, 06/17/2020 - 19:15
A new analysis uncovers the basis of the severe rainfall declines predicted by many models.

Antarctic sea ice loss explained in new study

Wed, 06/17/2020 - 19:14
Scientists have discovered that the summer sea ice in the Weddell Sea sector of Antarctica has decreased by one million square kilometers -- an area twice the size of Spain -- in the last five years, with implications for the marine ecosystem.

Half of the world's population exposed to increasing air pollution

Wed, 06/17/2020 - 16:09
Half of the world's population is exposed to increasing air pollution, new research has shown.

Switching from general to regional anaesthesia may cut greenhouse gas emissions

Wed, 06/17/2020 - 03:03
Switching from general to regional anaesthesia may help cut greenhouse emissions and ultimately help reduce global warming, indicates a real life example at one US hospital over the course of a year.

Coal-burning in Siberia after volcanic eruption led to climate change 250 million years ago

Tue, 06/16/2020 - 20:58
A team of researchers has provided the first ever direct evidence that extensive coal burning in Siberia is a cause of the Permo-Triassic Extinction, the Earth's most severe extinction event.

Why most of the records left by ancient rivers preserve commonplace processes

Tue, 06/16/2020 - 20:57
Researcher uncovers why most of the records left by ancient rivers preserve commonplace processes.

Hurricane season combined with COVID-19 pandemic could create perfect storm

Tue, 06/16/2020 - 18:39
When extreme climate conditions interact with stressors to social systems, such as the COVID-19 pandemic, the consequences could be severe unless experts from diverse backgrounds work together to develop comprehensive solutions to combat their negative impacts.

New species extinction target proposed for global nature rescue plan

Tue, 06/16/2020 - 18:39
A scientist proposes a prominent political target to give discussions of species conservation more vigor. Together with a group of experts from other research institutions, he proposes to limit species extinctions to 20 per year.

A carbon sink shrinks in the Arctic

Mon, 06/15/2020 - 22:21
Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean's ability to absorb carbon dioxide from the atmosphere into the deep ocean and store it there.

Clues to a dramatic chapter of Earth's geological history

Mon, 06/15/2020 - 21:09
How could the planet be covered entirely in ice -- a state known as 'Snowball Earth'-- and still give rise to multicellular life? The transition to such icy periods may not have been as abrupt as previously thought, new research shows.

New fossil discovery shows 50 million-year-old Canada-Australia connection

Mon, 06/15/2020 - 21:09
The discovery of a tiny insect fossil in Western Canada is unearthing big questions about the global movement of animals across deep time. The fossil, estimated to be 50 million years old, is the latest in a pattern of discoveries that are leading experts to contemplate a Canada-Australia connection not previously considered.

Carbon emission from permafrost soils underestimated by 14%

Mon, 06/15/2020 - 21:08
Picture 500 million cars stacked in rows. That's how much carbon -- about 1,000 petagrams, or one billion metric tons - -is locked away in Arctic permafrost.

A continental-scale prediction on the functional diversity of stream microbes

Mon, 06/15/2020 - 18:58
Climate mediates continental scale patterns of stream microbial functional diversity.

Remixed mantle suggests early start of plate tectonics

Fri, 06/12/2020 - 18:14
New research on the remixing of Earth's stratified deep interior suggests that global plate tectonic processes, which played a pivotal role in the existence of life on Earth, started to operate at least 3.2 billion years ago.

Impacts of climate change on migrating mule deer

Fri, 06/12/2020 - 18:14
The benefits of migration are likely to decrease for mule deer and other migratory herbivores as drought becomes more common due to ongoing climate change.

Protecting scientific diversity

Fri, 06/12/2020 - 18:13
The COVID-19 pandemic means that scientists face great challenges because they have to reorient, interrupt or even cancel research and teaching. A team of international scientists are highlighting the precarious situation of many scientists and calling for a collective effort by the scientific community, especially from its leadership, to protect decades of effort to build an inclusive scientific community.

New efficient ships won't be enough to curb shipping sector's environmental damage

Fri, 06/12/2020 - 03:38
New climate research has stated that urgent action on emissions from existing ships is the key to tackling shipping's impact on climate change.

Half the earth relatively intact from global human influence

Fri, 06/12/2020 - 01:39
If we act quickly and decisively, there is a slim window in which we can still conserve roughly half of Earth's land in a relatively intact state, a new study suggests.

Stiffer roadways could improve truck fuel efficiency

Fri, 06/12/2020 - 01:39
A theoretical study suggests that small changes in roadway paving practices could reduce that efficiency loss, potentially eliminating a half-percent of the total greenhouse gas emissions from the transportation sector, at little to no cost.

More than 1000 tons of plastic rains into Western US protected lands annually

Thu, 06/11/2020 - 22:14
Watershed researchers estimate more than 1000 tons of microplastics (equal to more than 123 million plastic water bottles) are deposited in national parks and wilderness areas each year. Researchers used high-resolution atmospheric deposition data and identified samples of microplastics and other particulates collected over 14 months in 11 western U.S. national parks and wilderness areas. They identified plastic and polymers' composition to identify sources of plastic emitted into the atmosphere and tracked its movement.
