Mangrove forests provide cause for conservation optimism, for now

Tue, 02/25/2020 - 17:49
An international team of researchers has found that globally, mangrove loss rates have reduced by almost an order of magnitude between the late 20th and early 21st century -- from what was previously estimated at one to three per cent per year, to about 0.3 to 0.6 per cent per year, thanks in large part to successful mangrove conservation efforts.

What to expect when you're expecting electric transportation

Tue, 02/25/2020 - 17:13
While electric vehicles alone may not reduce carbon emissions, a new study reveals that when electric vehicles are powered with renewable energy and coupled with carbon policy strategies, they can help combat climate change without sacrificing economic growth.

Reducing nutrient pollution helps coral resist bleaching

Tue, 02/25/2020 - 01:35
Coral reefs are not doomed. Although human activities threaten the iconic ecosystems in many different ways, scientists maintain that reefs can continue to thrive with the right assistance.

Quadrupling turbines, US can meet 2030 wind-energy goals

Tue, 02/25/2020 - 01:34
The United States could generate 20% of its electricity from wind within 10 years, without requiring any additional land, according to new research.

'Grand Challenge' review stresses global impact of microplastics

Mon, 02/24/2020 - 22:27
Microplastics are not just an ocean problem.

A plan to save Earth's oceans

Mon, 02/24/2020 - 17:05
At least 26 per cent of our oceans need urgent conservation attention to preserve Earth's marine biodiversity, a new study has found. Experts have said the international community needed to rapidly increase marine conservation efforts to maintain the health of the world's oceans.

Offshore wind farms could power much of coastal China

Fri, 02/21/2020 - 23:07
If China is to meet and exceed its Paris Climate Agreement goal by 2030, it's going to need to find a way to increase its wind capacity. Researchers found that offshore wind could be a big part of the solution.

Genetics of how corn can adapt faster to new climates

Fri, 02/21/2020 - 23:07
Researchers have decoded the genetic map for how maize from tropical environments can be adapted to the temperate US summer growing season. They believe that if they can expand the genetic base by using exotic varieties, they might be able to counter stresses such as emerging diseases and drought associated with growing corn in a changing climate.

New studies explore how knowledge drives action in climate change decision-making

Fri, 02/21/2020 - 01:27
In several new studies, researchers explore the importance of learning and knowledge in environmental decision-making and the different ways in which scientific knowledge can become more relevant and useful for societies.

DNA from ancient packrat nests helps unpack Earth's past

Thu, 02/20/2020 - 21:17
New work shows how using next-generation DNA sequencing on ancient packrat middens -- nests made out of plant material, fragments of insects, bones, fecal matter, and urine -- could provide ecological snapshots of Earth's past. The study may pave the way for scientists to better understand how plant communities -- and possibly animals, bacteria, and fungi as well -- will respond to human-caused climate change.

Old carbon reservoirs unlikely to cause massive greenhouse gas release

Thu, 02/20/2020 - 21:17
As global temperatures rise, permafrost and methane hydrates -- large reservoirs of ancient carbon -- have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. But would this methane actually reach the atmosphere? Researchers found that even if methane is released from these natural stores in response to warming, very little reaches the atmosphere; therefore, anthropogenic emissions should be more concerning than these natural feedbacks.

Huge stores of Arctic sea ice likely contributed to past climate cooling

Thu, 02/20/2020 - 20:05
Climate scientists propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago.

The climate and increased extreme weather affect our energy systems

Thu, 02/20/2020 - 20:05
Climate change, with more and more storms and heat waves, also has consequences for our energy supply. An international research team has now developed a new method for calculating how extreme weather affects energy systems.

'Wood' you like to recycle concrete?

Thu, 02/20/2020 - 17:11
Scientists studied a method for recycling unused concrete with wood fibers. They found the conditions that produce new building materials with bending strength even greater than the original concrete. This work may help reduce the CO2 emissions associated with manufacturing new concrete.

Illuminating interactions between decision-making and the environment

Thu, 02/20/2020 - 01:46
Employing a game theory model, researchers demonstrate how strategic decisions influence the environment in which those decisions are made, alterations which in turn influence strategy. Their analysis, which identifies how incentives can tip a strategy from one extreme to another, applies to fields as diverse as fisheries dynamics to climate change policy.

Jet stream not getting 'wavier' despite Arctic warming

Wed, 02/19/2020 - 22:28
Rapid Arctic warming has not led to a 'wavier' jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

Fish in the Sahara? Yes, in the early Holocene

Wed, 02/19/2020 - 21:37
Catfish and tilapia make up many of the animal remains uncovered in the Saharan environment of the Takarkori rock shelter in southwestern Libya, according to a new study.

Veggie-loving fish could be the new white meat

Wed, 02/19/2020 - 19:40
A secret to survival amid rising global temperatures could be dwelling in the tidepools of the US West Coast. Biologists studying the genome of an unusual fish residing in those waters offer new possibilities for humans to obtain dietary protein as climate change imperils traditional sources.

Methane emitted by humans vastly underestimated

Wed, 02/19/2020 - 18:37
Researchers measured methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels. The researchers indicate that reducing fossil fuel use is a key target in curbing climate change.

Wall Street investors react to climate change
