Water may be scarce for new power plants in Asia

Fri, 09/20/2019 - 19:46
Climate change and over-tapped waterways could leave developing parts of Asia without enough water to cool power plants in the near future, new research indicates. The study found that existing and planned power plants that burn coal for energy could be vulnerable.

Surface melting causes Antarctic glaciers to slip faster towards the ocean

Fri, 09/20/2019 - 18:13
Study shows for the first time a direct link between surface melting and short bursts of glacier acceleration in Antarctica. During these events, Antarctic Peninsula glaciers move up to 100% faster than average. Scientists call for these findings to be accounted for in sea level rise predictions.

Untapped resource, or greenhouse gas threat, found below rifting axis off Okinawa coast

Fri, 09/20/2019 - 18:13
Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers found a large-scale gas reservoir in an area where the Earth's upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.

Hurricane Nicole sheds light on how storms impact deep ocean

Thu, 09/19/2019 - 23:01
2016's Hurricane Nicole had a significant effect on the ocean's carbon cycle and deep sea ecosystems.

US and Canada have lost more than 1 in 4 birds in the past 50 years

Thu, 09/19/2019 - 21:23
Data show that since 1970, the US and Canada have lost nearly 3 billion birds, a massive reduction in abundance involving hundreds of species, from beloved backyard songbirds to long-distance migrants.

Division by subtraction: Extinction of large mammal species likely drove survivors apart

Thu, 09/19/2019 - 21:23
A new study suggests that the extinctions of mammoths, dire wolves and other large mammal species in North America drove surviving species to distance themselves from their neighbors, reducing interactions as predators and prey, territorial competitors or scavengers. The discovery could preview the ecological effects of future extinctions, the researchers say.

Investments to address climate change are good business

Thu, 09/19/2019 - 21:22
New research suggests that over the next few decades, acting to reduce climate change is expected to cost much less than the damage otherwise inflicted by climate change on people, infrastructure and ecosystems.

Cutting emissions gradually will avert sudden jump in warming

Wed, 09/18/2019 - 23:16
Steadily reducing fossil fuel emissions over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing a large spike in short-term warming that some studies predict, new analysis from finds. The finding dispels the misconception that the air-quality and climate benefits of transitioning to clean energy play out at different timescales -- a sticking point in recent climate negotiations.

Study of ancient climate suggests future warming could accelerate

Wed, 09/18/2019 - 21:20
The rate at which the planet warms in response to the ongoing buildup of heat-trapping carbon dioxide gas could increase in the future, according to new simulations of a comparable warm period more than 50 million years ago.

Dust from a giant asteroid crash caused an ancient ice age

Wed, 09/18/2019 - 21:20
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and new species evolved with the new temperatures. The cause of this ice age was a mystery, until now: a new study argues that the ice age was caused by global cooling, triggered by extra dust in the atmosphere from a giant asteroid collision in outer space.

Rethinking scenario logic for climate policy

Wed, 09/18/2019 - 20:15
Current scenarios used to inform climate policy have a weakness in that they typically focus on reaching specific climate goals in 2100 - an approach which may encourage risky pathways that could have long-term negative effects. A new study presents a novel scenario framework that focuses on capping global warming at a maximum level with either temperature stabilization or reversal thereafter.

Actions to save coral reefs could benefit all ecosystems

Wed, 09/18/2019 - 20:15
Scientists say bolder actions to protect the world's coral reefs will benefit all ecosystems, human livelihoods and improve food security.

Greenland's growing 'ice slabs' intensify meltwater runoff into ocean

Wed, 09/18/2019 - 20:15
Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, where the ice is normally porous and able to reabsorb meltwater. These slabs are instead sending meltwater spilling into the ocean, according to a new assessment, threatening to increase the country's contribution to sea level rise by as much as 2.9 inches by 2100.

Undervalued wilderness areas can cut extinction risk in half

Wed, 09/18/2019 - 20:14
Wilderness areas, long known for intrinsic conservation value, are far more valuable for biodiversity than previously believed, and if conserved, will cut the world's extinction risk in half, according to a new study.

Coastal birds can weather the storm, but not the sea

Wed, 09/18/2019 - 19:25
Coastal birds survive because their populations can absorb impacts and recover quickly from hurricanes -- even storms many times larger than anything previously observed.

Scientists forecasted late May tornado outbreak nearly 4 weeks in advance

Wed, 09/18/2019 - 19:25
Scientists report that they accurately predicted the nation's extensive tornado outbreak of late May 2019 nearly 4 weeks before it began.

Mechanism modeling for better forecasts, climate predictions

Wed, 09/18/2019 - 19:12
Modeling currents together with wind and waves provides more accurate predictions for weather forecasts and climate scientists.

Role of Tambora eruption in the 1816 'year without a summer'

Wed, 09/18/2019 - 02:36
A new study has estimated for the first time how the eruption of Mount Tambora changed the probability of the cold and wet European 'year without a summer' of 1816. It found that the observed cold conditions were almost impossible without the eruption, and the wet conditions would have been less likely.

March of the multiple penguin genomes

Wed, 09/18/2019 - 02:36
A new article presents 19 high-coverage penguin genome sequences. Adding this to the two previously published penguin genomes, there are now genome sequences available for all living penguin species. Here, the Penguin Genome Consortium, made up of researchers from 10 countries, has produced an unparalleled amount of information that covers an entire biological order. Research from evolution, the impact of human activities impact, and environmental changes, will benefit from this work.

Peatlands trap CO2, even during droughts

Tue, 09/17/2019 - 20:30
Scientists studied the two species of moss that make up the peatland. They discovered that in hot weather and drought conditions, one species resists, whereas the other is negatively impacted. In wet weather conditions the opposite takes place. Peatland however survives in the end. Although peatlands make up only 3% of the Earth's surface, they store one third of CO2 present in soil. Preserving peatlands would therefore limit the impact of future climate change.
