Climate change is the big wild card when it comes to the survival of many Arctic species. A new study shows that climate change will be both good and bad for Svalbard barnacle goose populations -- although the balance may tip depending upon the severity of future temperature increases, and how other species react.
A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).
Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers reporting in ACS' journal Environmental Science & Technology have studied natural sources of CO2 release off the coast of Italy, using what they learned to develop models that could be applied to future storage sites.
Set-aside patches of high-quality forest on palm oil plantations may help protect species like orangutans, as well as various species of insects, birds and bats -- many of which are threatened with extinction in areas of Indonesia and Malaysia, where 85% of the world's palm oil is produced.
By analysing 138 experiments, researchers have mapped the potential of today's plants and trees to store extra carbon by the end of the century.
National or other emissions inventories of greenhouse gases that are used to develop strategies and track progress in terms of emissions reductions for climate mitigation contain a certain amount of uncertainty, which inevitably has an impact on the decisions they inform. IIASA researchers contributed to several studies in a recently published volume that aims to enhance understanding of uncertainty in emissions inventories.
Scientists have developed a large-scale economical method to extract hydrogen (H2) from oil sands (natural bitumen) and oil fields. This can be used to power hydrogen-powered vehicles, as well as to generate electricity; hydrogen is regarded as an efficient transport fuel, similar to petrol and diesel, but with no pollution problems. The process can extract hydrogen from existing oil sands reservoirs. Interestingly, this process can be applied to mainstream oil fields, causing them to produce hydrogen instead of oil.
Since the first Homo sapiens emerged in Africa roughly 300,000 years ago, grasslands have sustained humanity and thousands of other species. But today, those grasslands are shifting beneath our feet. Global change -- which includes climate change, pollution and other widespread environmental alterations -- is transforming the plant species growing in them, and not always in the ways scientists expected, a new study published Monday revealed.
Detrimental economic effects of global warming are likely to go beyond those being discussed in policy circles -- particularly for wealthier nations, say researchers. Study suggests that 7% of global GDP will disappear by 2100 as a result of business-as-usual carbon emissions -- including over 10% of incomes in both Canada and the United States.
Bacteria found in muddy marshes, estuaries and coastal sediment synthesise one of the Earth's most abundant climate cooling gases -- according to new research from the University of East Anglia (UEA). Dimethylsulfoniopropionate (DMSP) is an important nutrient in marine environments with billions of tonnes produced annually by marine phytoplankton (microscopic plant-like cells), seaweed, corals and bacteria.
