Something old, something new in the ocean's blue

Wed, 11/13/2019 - 22:30
Microbiologists have discovered a new metabolic process in the ocean. Ranging from molecular structures of individual genes and detection of their global distribution, their results give insight into the pathway process and its degradation products and thus provide valuable information for future calculations of the ocean`s carbon dioxide balance.

Tuna carbon ratios reveal shift in food web

Wed, 11/13/2019 - 22:30
The ratio of carbon isotopes in three common species of tuna has changed substantially since 2000, suggesting major shifts are also taking place in the phytoplankton populations that form the basis of the ocean's food web, according to a new international study. Much of the change occurring in phytoplankton physiology and species composition may be driven by increased ocean stratification, an impact of climate change, the study suggests.

How everyday products are supercharging landfill gas, and what that means

Wed, 11/13/2019 - 22:30
Synthetic compounds increasingly used in everyday products like shampoo and motor oil are finding their way into landfills and supercharging the biogas those landfills produce, researchers have found.

Environmental cost of cryptocurrency mines

Wed, 11/13/2019 - 16:26
Bitcoin, Ethereum, Litecoin and Monero - the names of digital-based 'cryptocurrencies' are being heard more and more frequently. But despite having no physical representation, could these new methods of exchange actually be negatively impacting our planet? It's a question being asked by researchers who are investigating the environmental impacts of mining cryptocurrencies.

Healthy mangroves help coral reef fisheries under climate stress

Wed, 11/13/2019 - 16:25
Healthy mangroves can help fight the consequences of climate change on coral reef fisheries, according to a new study. Researchers say corals have been bleached and reefs have lost their structural complexity as a major consequence of warming seas.

Climate impact of hydropower varies widely

Wed, 11/13/2019 - 15:29
Hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels, and in many cases this is true. However, a new study reveals that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels.

Climate change expected to shift location of East Asian Monsoons

Wed, 11/13/2019 - 14:51
More than a billion people in Asia depend on seasonal monsoons for their water needs. The Asian monsoon is closely linked to a planetary-scale tropical air flow which, according to a new study, will most likely shift geographically as the climate continues to warm, resulting in less rainfall in certain regions.

Stalled weather patterns will get bigger due to climate change

Wed, 11/13/2019 - 14:51
Climate change will increase the size of stalled high-pressure systems that can cause heat waves, droughts and other extreme weather, according to a new study.

Ant expert discovers newly emergent species in his backyard

Wed, 11/13/2019 - 14:51
A global ant expert has traveled the world documenting and discovering ant species. But for his latest discovery, he didn't need to go any farther than his own backyard.

Individual climate models may not provide the complete picture

Tue, 11/12/2019 - 23:49
Equilibrium climate sensitivity -- how sensitive the Earth's climate is to changes in atmospheric carbon dioxide -- may be underestimated in individual climate models, according to a team of climate scientists.

Deep neural networks speed up weather and climate models

Tue, 11/12/2019 - 23:49
A team of environmental and computation scientists is using deep neural networks, a type of machine learning, to replace the parameterizations of certain physical schemes in the Weather Research and Forecasting Model, an extremely comprehensive model that simulates the evolution of many aspects of the physical world around us.

Ancient rain gauge: New evidence links groundwater, climate changes in deep time

Tue, 11/12/2019 - 19:26
Changes in groundwater millions of years ago created alternating layers of vivid yellow and brown in the mineral sphalerite, and those variations align with movements in Earth's orbit that impacted climate in the deep past, scientists found.

Last Arctic ice refuge is disappearing

Tue, 11/12/2019 - 18:40
The oldest and thickest Arctic sea ice is disappearing twice as fast as ice in the rest of the Arctic Ocean, according to new research.

This is what the monsoon might look like in a warmer world

Tue, 11/12/2019 - 18:02
In the last interglacial period on Earth about 125,000 years ago, the Indian monsoon was longer, more extreme and less reliable than it is today. This is the conclusion drawn after analyses of a dripstone from a cave in north-eastern India, combining various methods that provide information about supra-regional and local weather phenomena and the climate dynamics of the past.

Bacteria may contribute more to climate change as planet heats up

Tue, 11/12/2019 - 18:02
As bacteria adapt to hotter temperatures, they speed up their respiration rate and release more carbon, potentially accelerating climate change.

Nitrous oxide emissions set to rise in the Pacific Ocean

Tue, 11/12/2019 - 18:02
The acidification of the Pacific Ocean in northern Japan is increasing the natural production rate of N2O, an ozone-depleting greenhouse gas.

Hot town, springtime in the city: Urbanization delays spring plant growth in warm regions

Tue, 11/12/2019 - 16:57
The first appearance of bright green leaves heralds the start of spring. But a new study shows that urbanization shifts this seasonal cue in nuanced ways, with cities in cold climates triggering earlier spring plant growth and cities in warm climates delaying it.

Study shows where global renewable energy investments have greatest benefits

Tue, 11/12/2019 - 16:06
New study finds that the amount of climate and health benefits achieved from renewable energy depends on the country where it is installed. Countries with higher carbon dioxide (CO2) emissions and more air pollution, such as India, China, and areas in Southeast Asia and Eastern Europe, achieve greater climate and health benefits per megawatt (MW) of renewable energy installed than those operating in areas such as North America, Brazil, and parts of Europe.

Nature's backup plan for converting nitrogen into plant nutrients

Tue, 11/12/2019 - 01:01
Researchers have found that nature has developed a backup method for converting atmospheric nitrogen into the nutrient form critical to plant growth and soil fertility. The researchers report that the process known as nitrogen fixation can be carried out by the metal vanadium in ecosystems where the primary catalyst molybdenum is scarce. The study suggests that nature's capacity to restore ecosystems in the wake of human-made disturbances or fertilize agricultural land is more resilient than previously thought.

Finding common ground for scientists and policymakers on soil carbon and climate change

Mon, 11/11/2019 - 22:06
Scientists argue that public debate about the role of soil carbon in battling climate change is undermining the potential for policymakers to implement policies that build soil carbon for other environmental and agricultural benefits.
