Climate change is reshaping communities of ocean organisms

Mon, 11/25/2019 - 19:10
Climate change is reshaping communities of fish and other sea life, according to a pioneering study on how ocean warming is affecting the mix of species. The study covers species that are important for fisheries and that serve as food for fish, such as copepods and other zooplankton.

Meeting the challenges facing fisheries climate risk insurance

Mon, 11/25/2019 - 19:09
Insurance schemes with the potential to improve the resilience of global fisheries face a host of future challenges, researchers say.

A new world map rates food sustainability for countries across the globe

Mon, 11/25/2019 - 17:03
A global food system sustainability study builds the first map of its kind to score the sustainability of food systems, country-by-country. The study goes beyond usual questions of productivity and nutrition, and includes economic and social variables.

Samoa climate change resilience challenges Western perceptions

Fri, 11/22/2019 - 22:51
The resilience of Samoan communities in the face of climate change is providing a blueprint for other nations to follow, according to researchers.

Clean air research converts toxic air pollutant into industrial chemical

Fri, 11/22/2019 - 18:33
A toxic pollutant produced by burning fossil fuels can be captured from the exhaust gas stream and converted into useful industrial chemicals using only water and air thanks to a new advanced material.

Changing experiences of the natural world

Fri, 11/22/2019 - 18:32
Digital innovations have the potential to bring people closer to nature, to help ensure there is the necessary strong public support for conservation measures.

Grid reliability under climate change may require more power generation capacity

Thu, 11/21/2019 - 21:14
Researchers applied a new modeling approach for long-term planning of the U.S. power grid under future climate and water resource conditions. The new approach shows the grid may need an additional 5.3% to 12% of power-generating capacity to meet demand and reliability requirements. The changes would lower water use and carbon emissions, potentially helping mitigate future climate changes.

Fish in California estuaries are evolving as climate change alters their habitat

Thu, 11/21/2019 - 16:50
The threespine stickleback, a small fish found throughout the coastal areas of the Northern Hemisphere, is famously variable in appearance from one location to another, making it an ideal subject for studying how species adapt to different environments. A new study shows that stickleback populations in estuaries along the coast of California have evolved over the past 40 years as climate change has altered their coastal habitats.

Scientists develop rapid cell division in marine sponges

Thu, 11/21/2019 - 14:54
Despite efforts over multiple decades, there are still no cell lines for marine invertebrates. For the first time, scientists have developed a breakthrough in marine invertebrate (sponge) cell culture, demonstrating exceptionally fast cell division and the ability to subculture the cells. This groundbreaking discovery forms the basis for developing marine invertebrate cell models to better understand early animal evolution, determine the role of secondary metabolites, predict the impact of climate change to coral reef community ecology and develop novel medicines.

Researchers sequence genome of the 'devil worm'

Thu, 11/21/2019 - 14:54
Researchers have sequenced the genome of a unique microscopic worm found one mile underground and called the 'Devil Worm' for its ability to survive in harsh, subsurface conditions.

Dead-zone report card reflects improving water quality in Chesapeake Bay

Thu, 11/21/2019 - 00:56
The 2019 'dead-zone' report card for Chesapeake Bay indicates that the volume of low-oxygen, 'hypoxic' water was on the high end of the normal range, a finding that scientists consider relatively good news given the unfavorable weather conditions.

Vanishing ice puts reindeer herders at risk

Wed, 11/20/2019 - 21:18
Mongolia's Tsaatan reindeer herders depend on munkh mus, or eternal ice, for their livelihoods. Now, soaring global temperatures may threaten that existence.

Icebergs as a source of nutrients

Wed, 11/20/2019 - 19:11
The importance of icebergs as an important source of nutrients in the polar regions has long been discussed. An international research team has investigated ice samples worldwide. A key result is that only a small part of the glacier ice contaminated with sediment contains large amounts of iron, while the vast majority of clean ice contains very little iron.

Asking if behavior can be changed on climate crisis

Wed, 11/20/2019 - 19:11
One of the more complex problems facing social psychologists today is whether any intervention can move people to change their behavior about climate change and protecting the environment for the sake of future generations. Now researchers report that an intergenerational reciprocity approach, asking people to reflect on sacrifices made in the past by others for their benefit today, may generate a sense of moral obligation to future generations.

Wind more effective than cold air at cooling rooms naturally

Wed, 11/20/2019 - 19:11
The effectiveness of non-mechanical, low-energy methods for moderating temperature and humidity has been evaluated in a series of experiments.

New danger for corals in warming oceans: Metal pollution

Tue, 11/19/2019 - 23:14
Metal copper from agricultural runoff and marine paint leaching from boat hulls poses an emerging threat to soft coral sea fans in the waters around Puerto Rico.

Rare gas find solves puzzle of Southern Africa's soaring landscape

Tue, 11/19/2019 - 17:55
The discovery of gases released from deep beneath the Earth's crust could help to explain Southern Africa's unusual landscape, a study suggests.

Beyond the green revolution

Tue, 11/19/2019 - 17:54
There has been a substantial increase in food production over the last 50 years, but it has been accompanied by a narrowing in the diversity of cultivated crops. New research shows that diversifying crop production can make food supply more nutritious, reduce resource demand and greenhouse gas emissions, and enhance climate resilience without reducing calorie production or requiring more land.

Decarbonizing the power sector

Tue, 11/19/2019 - 14:53
Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts -- such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international team of researchers has now quantified the actual benefits and downsides of three main roads to decarbonization.

Boosting wind farmers, global winds reverse decades of slowing and pick up speed

Tue, 11/19/2019 - 14:53
In a boon to wind farms, average daily wind speeds are picking up across much of the globe after about 30 years of gradual slowing. Research shows that wind speeds in northern mid-latitude regions have increased by roughly 7% since 2010.
