Canada lynx disappearing from Washington state

Science Daily: Climate News - Thu, 04/09/2020 - 23:23
Canada lynx are losing ground in Washington state, even as federal officials are taking steps to remove the species' threatened status under the Endangered Species Act. A massive monitoring study has found the big cat on only about 20% of its potential habitat in the state.

Long-living tropical trees play outsized role in carbon storage

Science Daily: Climate News - Thu, 04/09/2020 - 21:15
A group of trees that grow fast, live long lives and reproduce slowly account for the bulk of the biomass -- and carbon storage -- in some tropical rainforests, a team of scientists says. The finding that these trees, called long-lived pioneers, play a much larger role in carbon storage than previously thought may have implications in efforts to preserve forests as a strategy to fight climate change.

Greenland ice sheet meltwater can flow in winter, too

Science Daily: Climate News - Thu, 04/09/2020 - 17:03
Liquid meltwater can sometimes flow deep below the Greenland Ice Sheet in winter, not just in the summer, according to new research.

Improving accuracy of future climate change predictions

Science Daily: Climate News - Thu, 04/09/2020 - 05:05
New research has shone light on the impact of clouds on climate change. The study has raised serious doubts of the likely impact of human-led interventions involving methods of cloud 'brightening' to counteract climate change.

Don't look to mature forests to soak up carbon dioxide emissions

Science Daily: Climate News - Wed, 04/08/2020 - 18:33
Research suggests mature forests are limited in their ability to absorb 'extra' carbon as atmospheric carbon dioxide concentrations increase.

Climate change could cause sudden biodiversity losses worldwide

Science Daily: Climate News - Wed, 04/08/2020 - 18:03
A warming global climate could cause sudden, potentially catastrophic losses of biodiversity in regions across the globe throughout the 21st century, finds a new study.

Carbon emission scheme 'succeeding despite low prices'

Science Daily: Climate News - Wed, 04/08/2020 - 17:49
A European Union (EU) program aimed at reducing carbon dioxide (CO2) emissions has made significant progress despite low prices in carbon markets, according to a new study.

New study helps improve accuracy of future climate change predictions

Science Daily: Climate News - Wed, 04/08/2020 - 17:49
New research has shone light on the impact of clouds on climate change. The study has raised serious doubts of the likely impact of human-led interventions involving methods of cloud 'brightening' to counteract climate change.

A rapidly changing Arctic

Science Daily: Climate News - Wed, 04/08/2020 - 17:21
A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift -- a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

Protecting the high seas: Identify biodiversity hotspots

Science Daily: Climate News - Tue, 04/07/2020 - 20:15
Researchers use big data to identify biodiversity hotspots that could become the first generation of high seas marine protected areas.

Adding a pinch of salt to El Niño models

Science Daily: Climate News - Tue, 04/07/2020 - 20:14
When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity -- or saltiness -- data significantly improves model accuracy, according to a new study.

Climate change triggers Great Barrier Reef bleaching

Science Daily: Climate News - Tue, 04/07/2020 - 17:18
The Great Barrier Reef is suffering through its worst bleaching event. This is the third bleaching within the space of five years.

More pavement, more problems

Science Daily: Climate News - Tue, 04/07/2020 - 02:04
Think your daily coffee, boutique gym membership and airport lounge access cost a lot? There may be an additional, hidden cost to those luxuries of urban living, says a new study: more flooding. For every percentage point increase in roads, parking lots and other impervious surfaces that prevent water from flowing into the ground, annual floods increase on average by 3.3%, the researchers found.

Societal transformations and resilience in Arabia across 12,000 years of climate change

Science Daily: Climate News - Tue, 04/07/2020 - 02:04
Recent archaeological and paleoenvironmental research in the Arabian Peninsula shows a range of societal responses to a series of extreme climatic and environmental fluctuations over thousands of years. These responses include migration, increasing population mobility, the introduction of pastoral lifeways, the management of water resources, and the construction of diverse structures to aid survival. Present-day constraints mean that many of these options are not available to populations living in the region today.

Indigenous knowledge could reveal ways to weather climate change on islands

Science Daily: Climate News - Tue, 04/07/2020 - 02:04
Some islands have such low elevation, that mere inches of sea-level rise will flood them, but higher, larger islands will also be affected by changes in climate and an understanding of ancient practices in times of climate change might help populations survive, according to researchers.

Upper ocean water masses shrinking in changing climate: Less efficient CO2 sink

Science Daily: Climate News - Mon, 04/06/2020 - 18:25
The oceans help buffer the Earth from climate change by absorbing carbon dioxide and heat at the surface and transporting it to the deep ocean. New research indicates the North Atlantic Subtropical Mode Water, an upper ocean water mass, is shrinking in a changing climate and becoming a less efficient sink for heat and carbon dioxide.

Climate change to affect fish sizes and complex food webs

Science Daily: Climate News - Mon, 04/06/2020 - 18:25
Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new study has shown. The study analyzed three decades of data from 30,000 surveys of rocky and coral reefs around Australia.

Deep-sea worms and bacteria team up to harvest methane

Science Daily: Climate News - Fri, 04/03/2020 - 23:27
Scientists uncover an unusual partnership at the bottom of the ocean.

Changes to drylands with future climate change

Science Daily: Climate News - Fri, 04/03/2020 - 18:51
While drylands around the world will expand at an accelerated rate because of future climate change, their average productivity will likely be reduced, according to a new study. These regions, which primarily include savannas, grasslands and shrublands, are important for grazing and non-irrigated croplands. They are also a critical part of the global carbon cycle and make up 41% of Earth's land surface and support 38% of its population.

Northern peatlands will lose some of their CO2 sink capacity under a warmer climate

Science Daily: Climate News - Fri, 04/03/2020 - 18:51
A study sheds new light on the role of northern peatlands in regulating the regional climate. According to the researchers, peatlands will remain carbon sinks until the end of this century, but their sink capacity will be substantially reduced after 2050, if the climate warms significantly.
