California's climate refugia: Mapping the stable places

Science Daily: Climate News - Tue, 06/09/2020 - 16:51
Some landscapes can hold their own against climate change better than others. A new study maps these places, called 'climate refugia,' where existing vegetation is most likely to buffer the impacts of climate change through the end of the century.

Scientists lament 'Humpty Dumpty' effect on world's spectacular, rare wildlife

Science Daily: Climate News - Tue, 06/09/2020 - 16:50
A new study reveals how runaway human population growth collapses the role of wildlife in the world's ecosystems.

Nature's 'slow lanes' offer hope for species feeling heat of climate change

Science Daily: Climate News - Tue, 06/09/2020 - 16:50
Pockets of landscape less prone than adjacent areas to disturbances like fire and drought may hold the key for scientists, conservationists and land managers seeking to preserve vulnerable species in a changing climate.

Temperate insects as vulnerable to climate change as tropical species

Science Daily: Climate News - Mon, 06/08/2020 - 19:23
In previous research, it has been assumed that insects in temperate regions would cope well with or even benefit from a warmer climate. Not so, according to researchers. The earlier models failed to take into account the fact that insects in temperate habitats are inactive for much of the year.

Countries must work together on CO2 removal to avoid dangerous climate change

Science Daily: Climate News - Mon, 06/08/2020 - 18:47
The Paris Agreement lays out national quotas on CO2 emissions but not removal, and that must be urgently addressed, say the authors of a new study.

Researchers advance fuel cell technology

Science Daily: Climate News - Mon, 06/08/2020 - 16:29
Researchers have made a key advance in solid oxide fuel cells (SOFCs) that could make the highly energy-efficient and low-polluting technology a more viable alternative to gasoline combustion engines for powering cars.

Climate change has degraded productivity of shelf sea food webs

Science Daily: Climate News - Mon, 06/08/2020 - 02:50
New research has shown that a shortage of summer nutrients -- a result of our changing climate -- has contributed to a 50% decline in important North East Atlantic plankton over the past 60 years.

American lobster, sea scallop habitat could shift off the northeast

Science Daily: Climate News - Fri, 06/05/2020 - 20:24
Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops on the Northeast U.S. continental shelf. They used a suite of models to estimate how species will react as waters warm. The researchers suggest that American lobster will move further offshore and sea scallops will shift to the north in the coming decades.

Study shows diamonds aren't forever

Science Daily: Climate News - Fri, 06/05/2020 - 17:54
Diamonds, those precious, sparkling jewels, are known as the hardest materials on Earth. They are a high-pressure form of carbon and found deep in the ground. While diamonds are commonly thought of as hard and stable, carbon from about 100 miles beneath the African plate is being brought to shallower levels where diamond will become unstable. Molten rock (magma) brings the excess carbon towards the surface, and earthquakes open cracks that allow the carbon to be released into the air as carbon dioxide.

Mangrove trees won't survive sea-level rise by 2050 if emissions aren't cut

Science Daily: Climate News - Thu, 06/04/2020 - 22:21
Mangrove trees -- valuable coastal ecosystems found in Florida and other warm climates - won't survive sea-level rise by 2050 if greenhouse gas emissions aren't reduced, according to a new study. Using sediment data from the last 10,000 years, an international team estimated the chances of mangrove survival based on rates of sea-level rise.

Vital buffers against climate change are just offshore

Science Daily: Climate News - Thu, 06/04/2020 - 18:37
A new study finds that about 31 million people worldwide live in coastal regions that are 'highly vulnerable' to future tropical storms and sea-level rise driven by climate change. But in some of those regions, powerful defenses are located just offshore, in the forms of mangroves and coral reefs, key buffers that could help cushion the blow against future tropical storms and rising waters.

New study reveals cracks beneath giant, methane gushing craters

Science Daily: Climate News - Thu, 06/04/2020 - 18:16
250-million-year-old cracks in the seafloor feed greenhouse gas methane into giant craters in the Barents Sea. More than 100 craters, presently expelling enormous amounts of the greenhouse gas into the ocean, are found in the area.

Climate change an imminent threat to glass sponge reefs

Science Daily: Climate News - Thu, 06/04/2020 - 16:56
Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new research. The findings indicate that ongoing climate change could have serious, irreversible impacts on the sprawling glass sponge reefs of the Pacific Northwest and associated biodiversity -- the only known reefs of their kind in the world.

Data gaps hamper monitoring of heavy metals that threaten Arctic communities

Science Daily: Climate News - Wed, 06/03/2020 - 21:43
Some Alaskan soils harbor elevated concentrations of heavy metals that can harm human health, but critical data gaps impede understanding of exposure risks for Arctic communities.

The need for conservation of natural springs in drying climate

Science Daily: Climate News - Wed, 06/03/2020 - 20:25
Researchers have described the importance of springs in a drying climate.

New record for carbon dioxide capture

Science Daily: Climate News - Wed, 06/03/2020 - 20:25
Researchers have set a record for carbon dioxide capture using Metal Organic Frameworks (MOFs). The technology resembles a sponge filled with tiny magnets.

Ocean uptake of carbon dioxide could drop as carbon emissions are cut

Science Daily: Climate News - Wed, 06/03/2020 - 20:00
The ocean is so sensitive to declining greenhouse gas emissions that it immediately responds by taking up less carbon dioxide, says a new study. The authors say we may soon see this play out due to the COVID-19 pandemic lessening global fuel consumption; they predict the ocean could take up less carbon dioxide in 2020 than in 2019.

Rivers help lock carbon from fires into oceans for thousands of years

Science Daily: Climate News - Wed, 06/03/2020 - 17:05
The extent to which rivers transport burned carbon to oceans - where it can be stored for tens of millennia - is revealed in new research. The study calculates how much burned carbon is being flushed out by rivers and locked up in the oceans. Oceans store a surprising amount of carbon from burned vegetation, for example as a result of wildfires and managed burning. The research team describe it as a natural - if unexpected - quirk of the Earth system.

New research deepens understanding of Earth's interaction with the solar wind

Science Daily: Climate News - Wed, 06/03/2020 - 01:34
Scientists have reproduced a process that occurs in space to deepen understanding of what happens when the Earth encounters the solar wind.

Reflecting sunlight to cool the planet will cause other global changes

Science Daily: Climate News - Tue, 06/02/2020 - 22:13
Study finds reflecting sunlight to cool the planet will weaken extratropical storm tracks, causing other global changes.
