Earth to reach temperature tipping point in next 20 to 30 years, new study finds

Wed, 01/13/2021 - 21:44
An international team looked at 20 years of data from throughout the world and found that record-breaking temperatures are contributing to a significant decrease in plants' ability to absorb human-caused carbon emissions.

Physical weathering of rock breakdown more important than previously recognized

Wed, 01/13/2021 - 21:44
Anisovolumetric weathering is much more common than previously thought, and variations in this process can be explained by climate and erosion.

Study looks at how land acquisitions affect climate change

Wed, 01/13/2021 - 20:24
Researchers looked at what drives large-scale land acquisitions and how the implementation of large-scale land acquisitions for agricultural development affect carbon emissions, and in turn, climate change.

Wetland methane cycling increased during ancient global warming event

Wed, 01/13/2021 - 19:07
Wetland methane cycling increased during a rapid global warming event 56 million years ago and could foreshadow changes the methane cycle will experience in the future, according to new research.

Northern lakes at risk of losing ice cover permanently, impacting drinking water

Wed, 01/13/2021 - 19:07
Close to 5,700 lakes in the Northern Hemisphere may permanently lose ice cover this century, 179 of them in the next decade, at current greenhouse gas emissions, despite a possible polar vortex this year, researchers have found. Those lakes include large bays in some of the deepest of the Great Lakes, such as Lake Superior and Lake Michigan, which could permanently become ice free by 2055.

Pollinators not getting the 'buzz' they need in news coverage

Wed, 01/13/2021 - 19:07
A dramatic decline in pollinating insects threatens the global food supply, yet it's getting 'vanishingly low levels of attention' in mainstream news, even compared to coverage of climate change. Researchers analyzed nearly 25 million news items from six prominent U.S. and global news sources using the university's massive Global News Index.

Red and green snow algae increase snowmelt in the Antarctic Peninsula

Wed, 01/13/2021 - 19:06
Red and green algae that grow on snow in the Antarctic Peninsula cause significant extra snowmelt on par with melt from dust on snow in the Rocky Mountains, according to a first-of-its-kind scientific research study. This could have serious impacts on regional climate, snow and ice melt, freshwater availability and ecosystems, yet is not accounted for in current global climate models.

Melting icebergs key to sequence of an ice age

Wed, 01/13/2021 - 19:06
Scientists claim to have found the 'missing link' in the process that leads to an ice age on Earth.

Copper-indium oxide: A faster and cooler way to reduce our carbon footprint

Wed, 01/13/2021 - 17:08
Emergent e-fuel technologies often employ the reverse water-gas shift (RWGS) reaction to convert atmospheric CO2 to CO. While efficient, this reaction requires high temperatures and complex gas separation for high performance. However scientists have now demonstrated record-high CO2 conversion rates at relatively low temperatures in a modified chemical-looping version of RWGS using a novel copper-indium oxide.

Framework sheds light on nitrogen loss of producing common food items

Wed, 01/13/2021 - 16:09
Differences in nitrogen loss intensity between livestock and crops confirm the need for change.

Expert prognosis for the planet - we're on track for a ghastly future

Wed, 01/13/2021 - 16:09
An international group of 17 leading scientists have produced a comprehensive yet concise assessment of the state of civilization, warning that the outlook is more dire and dangerous than is generally understood.

No-till practices in vulnerable areas significantly reduce soil erosion

Wed, 01/13/2021 - 00:38
Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it. Farmers implementing no-till practices can significantly reduce soil erosion rates, a new study shows.

Wildfire smoke is more cooling on climate than computer models assume

Tue, 01/12/2021 - 23:36
Many of the most advanced climate models simulate smoke that is darker, or more light absorbing, than what researchers see in observations.

Soil degradation costs U.S. corn farmers a half-billion dollars every year

Tue, 01/12/2021 - 19:52
One-third of the fertilizer applied to grow corn in the U.S. each year simply compensates for the ongoing loss of soil fertility, leading to more than a half-billion dollars in extra costs to U.S. farmers every year, finds new research.

A bucket of water can reveal climate change impacts on marine life in the Arctic

Tue, 01/12/2021 - 18:01
We know very little about marine life in the Arctic. Now researchers are trying to change that. They have shown that a simple water sample makes it possible to monitor the presence, migration patterns and genetic diversity of bowhead whales in an otherwise hard-to-reach area. The method can be used to understand how climate changes and human activities impact life in the oceans.

New study of Earth's crust shows global growth spurt three billion years ago

Tue, 01/12/2021 - 15:54
Researchers have used ancient crystals from eroded rocks found in stream sediments in Greenland to successfully test the theory that portions of Earth's ancient crust acted as 'seeds' from which later generations of crust grew.

Climate change reduces the abundance and diversity of wild bees

Tue, 01/12/2021 - 15:53
Wild bees are more affected by climate change than by disturbances to their habitats, according to a team of researchers. The findings suggest that addressing land-use issues alone will not be sufficient to protecting these important pollinators.

Future too warm for baby sharks

Tue, 01/12/2021 - 15:53
As climate change causes the world's oceans to warm, baby sharks are born smaller, exhausted, undernourished and into environments that are already difficult for them to survive in.

Climate change has caused billions of dollars in flood damages

Tue, 01/12/2021 - 02:01
Flooding has caused hundreds of billions of dollars in damage in the U.S. over the past three decades. Researchers found that 36 percent of the costs of flooding in the U.S. from 1988 to 2017 were a result of intensifying precipitation, consistent with predictions of global warming.

Number of people suffering extreme droughts will double

Mon, 01/11/2021 - 19:56
A global research effort offers the first worldwide view of how climate change could affect water availability and drought severity in the decades to come. By the late 21st century, global land area and population facing extreme droughts could more than double -- increasing from 3% during 1976-2005 to 7%-8%, according to a professor of civil and environmental engineering.
