If Russia's war in Ukraine significantly reduces grain exports, surging prices could worsen food insecurity, with increases up to 4.6% for corn and 7.2% for wheat. That also would have an environmental impact, with carbon emissions rising as additional land is used to grow crops.
Land in a cyclone’s wake becomes more vulnerable to forest fires
The strong winds and torrential rains that accompany a cyclone do tremendous damage to ecosystems, and this damage can make them more prone to future wildfires. As intense cyclones are projected to become more frequent worldwide, a team of researchers examines the links between cyclones and forest fires, how they...
Accurately tracking how plastic biodegrades
Researchers have developed an approach to accurately record and fully track the biodegradation of plastics in soils.
Strengthening cold ocean current buffers Galápagos Islands from climate change
New research shows that a cold equatorial ocean current -- which provides a buffer for the Galápagos Islands against an otherwise warming Pacific Ocean -- has been getting stronger for decades. It's encouraging news, and another reason to safeguard this UNESCO World Heritage Site, according to researchers.
Animals in national parks impacted by even just a few people
A new study has found that even in remote, rarely visited national parks, the presence of even just a few humans impacts the activity of wildlife that live there. Nearly any level of human activity in a protected area like a national park can alter the behavior of animals there,...
Does the Mediterranean diet really decrease your risk of dementia?
A number of studies have suggested that eating a healthy diet may reduce a person's risk of dementia, but a new study has found that two diets including the Mediterranean diet are not linked to a reduced risk of dementia.
Scientific plan for nature-based climate solutions
Ecosystem scientists and policy experts are calling for a scientific approach to nature-based climate solutions in the United States. The report is the result of dozens of scientists and policy experts gathering in Washington, D.C., in June to confront the consequences of climate change and ensure scientific footing for nature-based...
Clusters of genes help mice live longer
Researchers have announced the discovery of multiple candidate genes that influence longevity. The discovery of genetic loci that influence longevity only in females is interesting and important, according to the researchers. Genetic loci are clusters of between 10 and 100 genes.
Under pressure: Rethinking coastal land use and adaptation strategies
Researchers recently published a study looking at land use changes from the past and the importance of taking factors such as socio-economic development and the dynamic nature of coastal environments into consideration to make these areas more resilient to climate change.
Viewing Earth from space at night: tracking our changing black marble
A team of researchers has developed a method that is capable of providing daily global moderate resolution nighttime light change maps.
