Can sunlight convert emissions into useful materials?

Wed, 09/02/2020 - 00:54
A team of researchers has designed a method to break CO2 apart and convert the greenhouse gas into useful materials like fuels or consumer products ranging from pharmaceuticals to polymers. Typically, this process requires a tremendous amount of energy. However, in the first computational study of its kind, the research team enlisted a more sustainable ally: the sun.

Loggerhead turtles record a passing hurricane

Tue, 09/01/2020 - 18:22
Caught in an Atlantic hurricane, satellite-tagged loggerhead turtles changed their dive behavior and movement patterns as the storm passed. The tags also recorded changes in the environment.

Scientists unlock crops' power to resist floods

Mon, 08/31/2020 - 23:57
Foundational science has discovered the molecular structure of plant enzymes that could be manipulated to create flood-resistant crops, vital as weather events become more extreme due to global warming.

Warmer, acidifying ocean brings extinction for reef-building corals, renewal for relatives

Mon, 08/31/2020 - 18:23
A new study finds that reef-building corals emerged only when ocean conditions supported the construction of these creatures' stony skeletons, whereas diverse softer corals and sea anemones flourished at other times. Without a significant change to anthropogenic carbon emissions, the new findings present stark implications for the present and future of hard-bodied corals while suggesting a silver lining for the diversity of some of their softer-bodied relatives.

Humans' construction 'footprint' on ocean quantified for first time

Mon, 08/31/2020 - 18:23
In a world-first, the extent of human development in oceans has been mapped. An area totaling approximately 30,000 square kilometers - the equivalent of 0.008 percent of the ocean - has been modified by human construction, researchers say.

Sea level rise from ice sheets track worst-case climate change scenario

Mon, 08/31/2020 - 18:21
Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching the Intergovernmental Panel on Climate Change's worst-case climate warming scenarios.

Natural disasters must be unusual or deadly to prompt local climate policy change

Sat, 08/29/2020 - 03:49
Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study has found. Rather, policy change in response to extreme weather events appears to depend on a combination of factors, including fatalities, sustained media coverage, the unusualness of the event and the political makeup of the community.

Fossil trees on Peru's Central Andean Plateau tell a tale of dramatic environmental change

Fri, 08/28/2020 - 21:03
The anatomy of plant fossils including an enormous tree that grew 10 million years ago in the now arid, high-elevation Central Andean Plateau calls current paleoclimate models into question, suggesting that the area was more humid than models predict.

How Neanderthals adjusted to climate change

Fri, 08/28/2020 - 18:53
Climate change occurring shortly before their disappearance triggered a complex change in the behavior of late Neanderthals in Europe: they developed more complex tools, suggests new research.

Where marine heatwaves will intensify fastest: New analysis

Fri, 08/28/2020 - 17:21
High-resolution ocean modelling has found the world's strongest ocean currents, which play key roles in fisheries and ocean ecosystems, will experience more intense marine heatwaves than the global average over the coming decades.

Fidelity of El Niño simulation matters for predicting future climate

Fri, 08/28/2020 - 15:10
A new study revealed that correctly simulating ocean current variations hundreds of feet below the ocean surface - the so-called Pacific Equatorial Undercurrent - during El Niño events is key in reducing the uncertainty of predictions of future warming in the eastern tropical Pacific.

Songbirds reduce reproduction to help survive drought

Fri, 08/28/2020 - 00:21
New research suggests tropical songbirds in both the Old and New Worlds reduce reproduction during severe droughts, and this - somewhat surprisingly -- may actually increase their survival rates.

Using the past to maintain future biodiversity

Thu, 08/27/2020 - 21:13
New research shows that safeguarding species and ecosystems and the benefits they provide for society against future climatic change requires effective solutions which can only be formulated from reliable forecasts.

Civilization may need to 'forget the flame' to reduce CO2 emissions

Thu, 08/27/2020 - 21:12
Current world energy consumption is tied to unchangeable past economic production. And the way out of an ever-increasing rate of carbon emissions may not necessarily be ever-increasing energy efficiency -- in fact it may be the opposite.

Hurricanes could be up to five times more likely in the Caribbean if tougher targets are missed

Thu, 08/27/2020 - 20:06
Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the likelihood of such disasters in the region, according to new research.

Artificial intelligence learns continental hydrology

Thu, 08/27/2020 - 19:21
The data sets on the Earth's gravitational field which are required for this, stem from the GRACE and GRACE-FO satellite missions. Using the South American continent as an example, Earth system modellers have developed a new Deep-Learning-Method, which quantifies small as well as large-scale changes to the water storage with the help of satellite data.

Ocean acidification causing coral 'osteoporosis' on iconic reefs

Thu, 08/27/2020 - 19:21
Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which also influence coral growth. New research reveals the distinct impact that ocean acidification is having on coral growth on some of the world's iconic reefs.

Forest emissions: A chiral surprise in the rainforest

Thu, 08/27/2020 - 17:59
Reversed ratio of chiral volatile organic compounds over the Amazon rainforest reveal insects as unexplored important source of forest emissions.

Stop! Grand theft water

Thu, 08/27/2020 - 17:21
Researchers have developed a new method to better understand the drivers of water theft, a significant worldwide phenomenon, and deterrents to help protect this essential resource.

Misconceptions about weather and seasonality impact COVID-19 response

Thu, 08/27/2020 - 17:18
Misconceptions about the way climate and weather impact exposure and transmission of SARS-CoV-2, the virus that causes COVID-19, create false confidence and have adversely shaped risk perceptions, say researchers.
