Capturing CO2 with new self-forming membrane

Science Daily: Climate News - Fri, 05/01/2020 - 19:00
A new class of self-forming membrane has been developed. Capturing the carbon dioxide which can then be processed, the membrane dramatically reduced the demand for silver and the cost.

CO2 emissions from dry inland waters globally underestimated

Science Daily: Climate News - Fri, 05/01/2020 - 16:29
Inland waters play an important role in the global carbon cycle. Calculations that scale up the carbon dioxide emissions from land and water surface areas do not take account of inland waters that dry out intermittently. This means that the actual emissions from inland waters have been significantly underestimated -- as shown by the results of a recent international research project.

Ocean acidification prediction now possible years in advance

Science Daily: Climate News - Fri, 05/01/2020 - 16:29
Researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades.

Balancing impacts of range-shifting species: Invasives vs biodiversity

Science Daily: Climate News - Fri, 05/01/2020 - 00:09
For many years, the conservation community has embraced the idea that improving connectivity, that is, creating corridors so species can follow their preferred climate, will benefit biodiversity, says a researcher.

How catastrophic outburst floods may have carved Greenland's 'grand canyon'

Science Daily: Climate News - Thu, 04/30/2020 - 22:03
For years, geologists have debated how and when canyons under the Greenland Ice Sheet formed, especially one called 'Greenland's Grand Canyon.' Its shape suggests it was carved by running water and glaciers, but until now its genesis remained unknown, scientists say.

First results from NASA's ICESat-2 mission map 16 years of melting ice sheets

Science Daily: Climate News - Thu, 04/30/2020 - 22:01
By comparing new measurements from NASA's ICESat-2 mission with the original ICESat mission, which operated from 2003 to 2009, scientists were able to measure precisely how the Greenland and Antarctic ice sheets have changed over 16 years.

Some of the latest climate models provide unrealistically high projections of future warming

Science Daily: Climate News - Thu, 04/30/2020 - 18:30
A new study from climate researchers concludes that some of the latest-generation climate models may be overly sensitive to carbon dioxide increases and therefore project future warming that is unrealistically high.

Navigating the clean energy transition during the COVID-19 crisis

Science Daily: Climate News - Wed, 04/29/2020 - 22:28
In a Commentary published April 29 in the journal Joule, energy and climate policy researchers in Switzerland and Germany provide a framework for responsibly and meaningfully integrating policies supporting the clean energy transition into the COVID-19 response in the weeks, months, and years to come.

Understanding deer damage is crucial when planting new forests

Science Daily: Climate News - Tue, 04/28/2020 - 20:17
Scientists say understanding the risk of damage by deer to new and existing forests in Britain is crucial when considering their expansion.

Agricultural pickers in US to see unsafely hot workdays double by 2050

Science Daily: Climate News - Tue, 04/28/2020 - 20:17
Temperature increases by 2050 and 2100 in U.S. counties where crops are grown will double, then triple the number of unsafe workdays. The study also looks at strategies the industry could adopt to protect workers' health.

Glacier detachments: A new hazard in a warming world?

Science Daily: Climate News - Tue, 04/28/2020 - 20:17
On the evening of 5 August 2013, a startling event occurred deep in the remote interior of the United States' largest national park. A half-kilometer-long tongue of Alaska's Flat Creek glacier suddenly broke off, unleashing a torrent of ice and rock that rushed 11 kilometers down a rugged mountain valley into the wilderness encompassed by Wrangell-St. Elias National Park and Preserve.

Arctic wildlife uses extreme method to save energy

Science Daily: Climate News - Tue, 04/28/2020 - 18:24
The extreme cold, harsh environment and constant hunt for food means that Arctic animals have become specialists in saving energy. Now, researchers have discovered a previously unknown energy-saving method used by birds during the polar night.

Honey bees could help monitor fertility loss in insects due to climate change

Science Daily: Climate News - Mon, 04/27/2020 - 18:01
New research could help scientists track how climate change is impacting the birds and the bees... of honey bees.

Climate change may push some species to higher elevations -- and out of harm's way

Science Daily: Climate News - Fri, 04/24/2020 - 22:07
A new study reveals that mountain-dwelling species fleeing warming temperatures by retreating to higher elevations may find refuge from reduced human pressure.

Diverse livelihoods helped resilient Levänluhta people survive a climate disaster

Science Daily: Climate News - Fri, 04/24/2020 - 20:25
A multidisciplinary research group dated the bones of dozens of Iron Age residents of the Levänluhta site in Finland, and studied the carbon and nitrogen stable isotope ratios. The results provide an overview of the dietary habits based on terrestrial, marine and freshwater ecosystems, as well as of sources of livelihoods throughout the Levänluhta era.

Warming climate undoes decades of knowledge of marine protected areas

Science Daily: Climate News - Fri, 04/24/2020 - 15:16
A new study highlights that tropical coral reef marine reserves can offer little defence in the face of climate change impacts. And the changes that are being observed will force scientists, conservationists and reserve managers to rethink the role these protected areas can bring.

No time to waste to avoid future food shortages

Science Daily: Climate News - Fri, 04/24/2020 - 04:26
Plant scientists are working on improving photosynthesis on different fronts, from finding crop varieties that need less water, to tweaking parts of the process in order to capture more carbon dioxide and sunlight to ensure future global food security. These solutions have been highlighted in a recent Food Security Special issue of the Journal of Experimental Botany.

Iron deficiency in corals?

Science Daily: Climate News - Thu, 04/23/2020 - 21:31
When iron is limited, the microalgae that live within coral cells change how they take in other trace metals, which could have cascading effects on vital biological functions and perhaps exacerbate the effects of climate change on corals.

Caribbean coral reef decline began in 1950s and 1960s from local human activities

Science Daily: Climate News - Thu, 04/23/2020 - 04:40
Fossil data, historical records, and underwater survey data have been used to reconstruct the abundance of staghorn and elkhorn corals over the past 125,000 years. Researchers show that these corals first began declining in the 1950s and 1960s, earlier than previously thought.

Human-caused warming will cause more slow-moving hurricanes, warn climatologists

Science Daily: Climate News - Wed, 04/22/2020 - 22:13
Hurricanes moving slowly over an area can cause more damage than faster-moving storms, and rising global temperatures will likely cause more mid-latitude hurricanes to slow down, said a team of climatologists. They used a large ensemble of climate simulations to explore the link between anthropogenic climate warming and hurricane movement speed.
