Concrete solutions that lower both emissions and air pollution

Mon, 03/23/2020 - 19:24
Some common strategies to reduce the greenhouse gas emissions of concrete production could have unintended consequences for local air pollution and related health damages, according to a new study.

Which forests in Borneo are most in need of protection?

Mon, 03/23/2020 - 19:24
Researchers are working to help identify priority forest areas for protection on Borneo.

East Antarctica's Denman Glacier has retreated almost 3 miles over last 22 years

Mon, 03/23/2020 - 18:56
East Antarctica's Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.

Coal exit benefits outweigh its costs

Mon, 03/23/2020 - 18:56
Coal combustion is not only the single most important source of CO2 -- accounting for more than a third of global emissions, but also a major contributor to detrimental effects on public health and biodiversity. Yet, globally phasing out coal remains one of the hardest political nuts to crack.

Electric cars better for climate in 95% of the world

Mon, 03/23/2020 - 18:56
Fears that electric cars could actually increase carbon emissions are unfounded in almost all parts of the world, new research shows.

Hidden source of carbon found at the Arctic coast

Sat, 03/21/2020 - 15:32
A new study has shown evidence of undetected concentrations and flows of dissolved organic matter entering Arctic coastal waters coming from groundwater flows on top of frozen permafrost. This water moves from land to sea unseen, but researchers now believe it carries significant concentrations of carbon and other nutrients to Arctic coastal food webs.

Epigenetic inheritance: A silver bullet against climate change?

Sat, 03/21/2020 - 01:27
The rapid pace of climate change threatens all living species. An international team of researchers has demonstrated that fish living in the Baltic Sea evolve using epigenetic mechanisms, yet to a lesser extent than previously hypothesized.

The right dose of geoengineering could reduce climate change risks

Fri, 03/20/2020 - 02:06
Injecting the right dose of sulphur dioxide into Earth's upper atmosphere to thicken the layer of light reflecting aerosol particles artificially could reduce the effects of climate change overall, exacerbating change in only a small fraction of places, according to new research.

Shedding light on how much carbon tropical forests can absorb

Thu, 03/19/2020 - 15:02
Tropical forest ecosystems are an important part of the global carbon cycle as they take up and store large amounts of CO2. It is however uncertain how much these forests' ability to take up and store carbon differ between forests with high versus low species richness. New research sheds light on this question aiming to enhance our ability to predict tropical ecosystems' strength as global carbon sinks.

Heatwaves risky for fish

Wed, 03/18/2020 - 20:37
A world-first study using sophisticated genetic analysis techniques have found that some fish are better than others at coping with heatwaves. The study tracks wild fish populations during a severe marine heatwave that killed a third of the Great Barrier Reef corals.

Global warming influence on extreme weather events has been frequently underestimated

Wed, 03/18/2020 - 20:37
Analysis shows global warming is intensifying the occurrence of unprecedented hot spells and downpours faster than predicted by historical trends.

Crop diversity can buffer the effects of climate change

Wed, 03/18/2020 - 20:37
Researchers found that farms with diverse crops planted together provide more secure, stable habitats for wildlife and are more resilient to climate change than the single-crop standard that dominates today's agriculture industry.

Greenland shed ice at unprecedented rate in 2019; Antarctica continues to lose mass

Wed, 03/18/2020 - 20:36
Scientists describe Greenland's loss of 600 billion tons of ice in the summer of 2019, raising global sea levels by 2.2 millimeters in a short time.

Increasingly mobile sea ice risks polluting Arctic neighbors

Wed, 03/18/2020 - 20:36
The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research.

Sugar brings a lot of carbon dioxide into the deeper sea

Wed, 03/18/2020 - 16:44
The oceans are a very important reservoir for carbon in the system of the earth. However, many aspects of the marine carbon cycle are still unknown. Scientists have now found that sugar plays an important role in this process. At the same time, the sweet energy source is important for the ecosystem of the oceans.

Comparisons of organic and conventional agriculture need to be better, say researchers

Wed, 03/18/2020 - 16:44
The environmental effects of agriculture and food are hotly debated. But the most widely used method of analysis often tends to overlook vital factors, such as biodiversity, soil quality, pesticide impacts and societal shifts. These oversights can lead to wrong conclusions on the merits of intensive and organic agriculture, according to a trio of researchers.

Emissions of several ozone-depleting chemicals are larger than expected

Tue, 03/17/2020 - 19:07
Researchers have found that much of the current emission of these gases likely stems from large CFC 'banks' -- old equipment such as building insulation foam, refrigerators and cooling systems, and foam insulation, that was manufactured before the global phaseout of CFCs and is still leaking the gases into the atmosphere. Based on earlier analyses, scientists concluded that CFC banks would be too small to contribute very much to ozone depletion, and so policymakers allowed the banks to remain.

How horses can save the permafrost

Tue, 03/17/2020 - 16:38
Permafrost soils in the Arctic are thawing. In Russia, experiments are now being conducted in which herds of horses, bison and reindeer are being used to combat this effect. A study shows for the first time that this method could significantly slow the loss of permafrost soils. Theoretically speaking, 80 percent of all permafrost soils around the globe could be preserved until the year 2100.

Mysterious bone circles made from the remains of mammoths reveal clues about Ice Age

Tue, 03/17/2020 - 02:46
Mysterious bone circles made from the remains of dozens of mammoths have revealed clues about how ancient communities survived Europe's ice age.

Even a limited India-Pakistan nuclear war would bring global famine, says study

Mon, 03/16/2020 - 21:22
A new multinational study incorporating the latest models of global climate, crop production and trade examines the possible effects of a nuclear exchange between two longtime enemies: India and Pakistan. It suggests that even a limited war between the two would cause unprecedented planet-wide food shortages and probable starvation lasting more than a decade.
