Monarch Butterfly Populations Are Plummeting

Both Eastern and Western monarch butterflies are seeing their populations plummet precipitously, worrying scientists that the future of the species is in peril, according to multiple surveys of butterfly populations. The New York Times recently reported on efforts to track the Western monarch butterfly, which spends its winter on California's central coast before heading off to…

Warming, acidic oceans may nearly eliminate coral reef habitats by 2100

Rising sea surface temperatures and acidic waters could eliminate nearly all existing coral reef habitats by 2100, suggesting restoration projects in these areas will likely meet serious challenges, according to new research presented in San Diego at the Ocean Sciences Meeting 2020. Scientists project 70 to 90 percent of coral reefs will disappear over the…

Poor water conditions drive invasive snakeheads onto land

The largest fish to walk on land, the voracious northern snakehead, will flee water that is too acidic, salty or high in carbon dioxide—important information for future management of this invasive species Snakeheads eat native species of fish, frogs and crayfish, destroying the food web in some habitats. They can survive on land for up to…

Scientists isolate drought-resistant gene in barley

The discovery of a gene in barley responsible for drought resistance will help future-proof crops against some of the effects of climate change, scientists believe. Researchers spent nearly five years isolating the specific gene – HvMYB1 – from more than 39,000 genes in barley. Tests proved that plants in which the gene is more prominently…

How trees could save the climate

Around 0.9 billion hectares of land worldwide would be suitable for reforestation, which could ultimately capture two thirds of human-made carbon emissions. The Crowther Lab of ETH Zurich has published a study in the journal Science that shows this would be the most effective method to combat climate change. The Crowther Lab at ETH Zurich investigates nature-based…

Nearly a quarter of West Antarctic ice is now unstable

By combining 25 years of European Space Agency satellite altimeter measurements and a model of the regional climate, the UK Centre for Polar Observation and Modelling (CPOM) have tracked changes in snow and ice cover across the continent. A team of researchers, led by Professor Andy Shepherd from the University of Leeds, found that Antarctica's…
