The onset date of the yearly rainy season reliably predicts if seasonal drought will occur in parts of Sub-Saharan Africa that are particularly vulnerable to food insecurity, and could help to mitigate its effects. Shraddhanand Shukla and colleagues at the University of California, Santa Barbara's Climate Hazards Center, present these findings in the open-access journal PLOS ONE on January 20, 2021.
A four-year study recently published in Ecology and Evolution concludes that the fungal disease, white-nose syndrome, poses a severe threat to many western North American bats.
India has an energy problem. It currently relies heavily on coal and consumer demand is expected to double by 2040, making its green energy targets look out of reach. Part of the solution could come from harvesting energy from footsteps, say Hari Anand and Binod Kumar Singh from the University of Petroleum and Energy Studies in Dehradun, India. Their new study, published in the De Gruyter journal Energy Harvesting and Systems, shows that Indian attitudes towards power generated through piezoelectric tiles are overwhelmingly positive.
No insect crisis in the Arctic - yet. Climate change is more pronounced in the Arctic than anywhere else on the planet, raising concerns about the ability of wildlife to cope with the new conditions. A new study shows that rare insects are declining, suggesting that climatic changes may favour common species.
In order to achieve the goals of the Paris Agreement, the world must reach net-zero carbon emissions by 2050. Carbon pricing is viewed by many governments and experts as the most important climate policy instrument. However, a new study shows that carbon pricing has been less effective as a driver of technological change than was previously anticipated.
A review of ten types of policy used to reduce carbon suggests that some costs fall on those less able to bear them - but it also shows these policies can form the bedrock of a 'green recovery' if specifically designed and used in tandem.
Researchers from the University of Tsukuba have found that ocean acidification limits algal communities to a state of low diversity and complexity. Communities grown in waters rich in carbon dioxide (CO2) were dominated by turf algae, and had low biodiversity, ecological complexity and biomass. Communities grown under acidic conditions and then transferred to waters that weren't CO2-enriched increased their biodiversity and complexity, showing that they can recover if CO2 emissions are significantly reduced.
Partially protected marine areas create confusion and don't meet their broad conservation objectives, UNSW researchers have found.
With a combined century of experience in the tropics, the University of Pennsylvania's Daniel Janzen and Winnie Hallwachs have seen a striking contraction of insect numbers and diversity. They share new data suggesting that climate change is the culprit and a way to protect the survivors: a bioliteracy program that aims to educate Costa Rican residents about the diversity around them and empower them to conserve it. It's a model they hope catches on and spreads around the globe.
A new CMCC global and free access dataset of 35 bioclimatic indicators just presented on Nature Scientific Data. It will complement and enlarge the availability of spatialized bioclimatic information, crucial aspect in many ecological and environmental studies and for several disciplines, including forestry, biodiversity conservation, plant and landscape ecology.
