New knowledge about ice sheet movement can shed light on when sea levels will rise      (via sciencedaily.com) 

The trawling of thousands of satellite measurements using artificial intelligence has shown researchers that meltwater in tunnels beneath Greenland's ice sheet causes it to change speed, and in some places, accelerate greatly towards the ocean. This can increase melting, especially in a warming climate, which is why the study's researchers think that it is important to keep an eye on.

Detecting the impact of drought on plants with user-friendly and inexpensive techniques      (via sciencedaily.com) 

Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.

Feedback loops make climate action even more urgent, scientists say      (via sciencedaily.com) 

Researchers have identified 26 global warming accelerators known as amplifying feedback loops that the researchers say aren't being properly included in climate models. They note that the findings add urgency to the need to respond to the climate crisis and provide a roadmap for policymakers aiming to avert the most severe consequences of a warming planet.

Keeping drivers safe with a road that can melt snow, ice on its own      (via sciencedaily.com) 

Slipping and sliding on snowy or icy roads is dangerous. Salt and sand help melt ice or provide traction, but excessive use is bad for the environment. And sometimes, a surprise storm can blow through before these materials can be applied. Now, researchers ave filled microcapsules with a chloride-free salt mixture that's added into asphalt before roads are paved, providing long-term snow melting capabilities in a real-world test.

Endangered Bahamas bird may be lost from island following hurricane      (via sciencedaily.com) 

The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.

Severe weather straining electrical grids: New research mitigates demand surges, increasing grid reliability and reducing costs      (via sciencedaily.com) 

Concerns are mounting among policymakers and utility companies amid the impact of severe weather on the nation's electrical grids. In recent months, electrical grids in Texas have been tested to the point of near failure. So it seems like perfect timing that new research identifies a new method that provides the best way to utilize 'direct load control contracts' to mitigate electricity demand surges, increase grid reliability and reduce electricity cost. All of this right down to the individual household.

New research suggests drought accelerated empire collapse      (via sciencedaily.com)     Original source 

The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, scientists have used tree ring and isotope records to pinpoint a more likely culprit: three straight years of severe drought.

Devastating cost of future coastal flooding for many developing nations predicted in new study      (via sciencedaily.com) 

New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.

Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time      (via sciencedaily.com) 

New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.

More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice      (via sciencedaily.com) 

The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.

Pacific Northwest heat dome tree damage more about temperature than drought, scientists say      (via sciencedaily.com)     Original source 

Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.

Voiceless frog discovered in Tanzania      (via sciencedaily.com)     Original source 

Researchers discovered a new species of frog in Africa that has an unusual trait: it's completely silent. The Ukaguru spiny-throated reed frog does not croak, sing or ribbit. Found in Tanzania's Ukaguru Mountains for which it is named, Hyperolius ukaguruensis is among the few frogs around the world that do not vocalize to other frogs.

Climate change may cut US forest inventory by a fifth this century      (via sciencedaily.com)     Original source 

A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both in the South.

Over 4% of summer mortality in European cities is attributable to urban heat islands      (via sciencedaily.com)     Original source 

Over four percent of deaths in cities during the summer months are due to urban heat islands, and one third of these deaths could be prevented by reaching a tree cover of 30%, according to a modelling study. The study results, obtained with data from 93 European cities, highlight the substantial benefits of planting more trees in cities to attenuate the impact of climate change.
