Land-based microbes may be invading and harming coral reefs A new study suggests that coral reefs -- already under existential threat from global warming -- may be undergoing further damage from invading bacteria and fungi coming from land-based sources, such as outfall from sewage treatment plants and coastal inl
How improved valves let grasses 'breathe,' cope with climate change New work from a joint team of plant biologists and ecologists has uncovered the factor behind an important innovation that makes grasses -- both the kind that make up native prairies and the kind we've domesticated for crops -- among the most-common and w
The carbon dioxide loop Marine biologists quantify the carbon consumption of bacterioplankton to better understand the ocean carbon cycle.
Outwitting climate change with a plant 'dimmer'? Plants possess molecular mechanisms that prevent them from blooming in winter. Once the cold of winter has passed, they are deactivated. However, if it is still too cold in spring, plants adapt their blooming behavior accordingly. Scientists from the Tech
No publication bias found in climate change research Rarely do we encounter a scientific fact that stirs public controversy and distrust in science as much as climate change. However, the theory is built on honest reporting of facts. This emerges from a new study from Lund University in Sweden.
A new study provides a solid evidence for global warming The new study allows a more accurate assessment of how much heat has accumulated in the ocean (and Earth) system. It will be a valuable resource for future studies of oceanic variability and its climatic impacts on both regional and global scales.
Measurements by school pupils paved way for key research findings With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming, now published in the journal Scientific Reports.

The cold exterminated all of them Researchers from UNIGE discovered that the extinction from Permian-Triassic took place during a short ice age which preceded the global climate warming. It's the first time that scientists have been able to assess the major role played by volcanic explosi
To improve our political climate, change the questions we ask Our fractured political climate in the United States might be made worse by how we approach difficult problems, researchers say in the journal Science. A team of political scientists suggests rather than asking citizens 'What do you want,' questions shoul
WMO verifies highest temperatures for Antarctic Region The World Meteorological Organization announced today new verified record high- temperatures in Antarctica, ranging from the high 60s (in Fahrenheit) to the high teens, depending on the location they were recorded in Antarctica. Knowledge and verification
Calculating recharge of groundwater more precisely An international team of researchers has demonstrated that key processes in models used for the global assessment of water resources for climate change are currently missing. This could mean climate change impact models are wrong in some parts of the wor
Climate research needs greater focus on human populations How climate change will affect future populations will depend to a great extent on people's capacity to adapt to changing conditions. Such characteristics can be forecast in the long term, using well-established demographic methods, argue researchers from
Transforming the carbon economy A task force commissioned in 2016 by former U.S. Secretary of Energy Ernest Moniz has proposed a framework for evaluating R&D on recycling carbon dioxide and removing large amounts of CO2 from the atmosphere. The goal is to produce a global emissions
Forests to play major role in meeting Paris climate targets Forests are set to play a major role in meeting the objectives of the Paris Climate Agreement -- however, accurately monitoring progress toward the 'below 2°C' target requires a consistent approach to measuring the impact of forests on greenhouse gas
How to reduce the environmental impact of a loaf of bread? With an estimated 12 million loaves sold in the UK every year, bread remains a staple of the British diet. In a groundbreaking study researchers from the University of Sheffield have now calculated the environmental impact of a loaf of bread and which par
Melting polar ice, rising sea levels not only climate change dangers 'Discussions of climate change usually are focused on changes occurring in polar and temperate zones, but tropical regions also are expected to experience changes in regional precipitation,' said Dr. Kirk Winemiller, AgriLife Research fisheries scientist
Light-driven reaction converts carbon dioxide into fuel Duke University researchers have developed tiny nanoparticles that help convert carbon dioxide into methane using only ultraviolet light as an energy source.
