Trees get overheated in a warmer rainforest

The ability of rainforests to store carbon can decrease in pace with climate change. This is due to photosynthesis rates in the leaves of rainforest species falling at higher temperatures and the trees’ natural cooling systems failing during droughts. Increased heat threatens especially the species that store most carbon.

Fasting-mimicking diet reduces signs of dementia in mice

Cycles of a diet that mimics fasting appear to reduce signs of Alzheimer’s in mice genetically engineered to develop the illness, according to a new study. Short cycles of a low-calorie diet that replicates fasting appeared to reduce inflammation and delay cognitive decline in mouse models of Alzheimer’s disease; initial data indicates diet’s safety in …

No environmental justice, no positive peace — and vice versa

Peace and environmental sustainability — two lofty but vital goals for all countries — are known to be intrinsically related, according to new research. However, researchers still tend to investigate them separately, and, when they are viewed together, it is often with broad strokes, with little examination into the nuances of either peace or environmental …

It may already be too late to meet UN genetic diversity target, but new findings could guide conservation efforts

Climate change and habitat destruction may have already caused the loss of more than one-tenth of the world’s terrestrial genetic diversity, according to new research. This means that it may already be too late to meet the United Nations’ proposed target, announced last year, of protecting 90 percent of genetic diversity for every species by …

Air pollution can amplify negative effects of climate change, new study finds

The impacts of air pollution on human health, economies, and agriculture differ drastically depending on where on the planet the pollutants are emitted, according to a new study that found that In some cases, pollution co-emitted with CO2 can increase the social cost of carbon by as much as 66%.The impacts of air pollution on …

Invasive stink bug habitat could expand greatly with climate change

A foul-smelling, voracious, wide-spread pest could become even more ubiquitous with climate change. A recent modelling study found that changing weather could increase suitable habitat for the brown marmorated stink bug in the United States by 70%. The study draws on data from a three-year stink bug monitoring effort in 17 states as well as …
