Llamas could help replenish plant life after glaciers retreat

The rapid retreat of glaciers from alpine regions around the world could result in widespread ecosystem losses, according to new research. Now, scientists are exploring a hairy solution to this hairy problem in the form of llamas.

Monitoring conflict and climate could help stop famines before they happen

Deaths due to famine have fallen precipitously in recent decades, but undernutrition, which affects one in five children worldwide, remains rampant. Now, researchers are using satellite imagery and social media to detect food-scarce regions before they become full-blown crises.

Climate change driving expansion of Lyme disease in the US

A new study finds increasing average winter temperatures are driving up reported Lyme disease cases in the Northeast and Midwest, especially near the outer limits of tick habitats where warmer winters boost tick survival rates and ability to find hosts. Public health officials are even seeing the disease spread to parts of Canada, in areas where it has never been seen before.

Wildfire residue may contribute to climate change

Wildfires leave behind large swathes of blackened earth when they raze a landscape. That charred material contains a host of molecules that could continue to release carbon dioxide into the atmosphere days and weeks after the fire has gone out, according to new research.

Unprecedented 2018 Bering Sea ice loss repeated in 2019

Sea ice in the Bering Sea reached record-low levels during winter 2018, thanks to persistent warm southerly winds. These conditions caused the ice to retreat to the northern reaches of the 800,000 square mile body of water. By the end of April 2018, sea ice was about 10 percent of normal. And then, much to scientists’ surprise, 2019 just missed eclipsing the record set in 2018.

One third of the African urban population exposed to extreme heat by 2090

An international team of researchers has combined demographic projections and climate scenarios across Africa for the first time. Rapid urbanization combined with climate change is having a major impact on the living conditions of city-dwellers in Africa, especially in terms of exposure to extreme – or even lethal – temperatures.

Using the past to unravel the future of Arctic wetlands

The study found that under 21st century warming conditions and with adequate moisture, certain Arctic wetlands may transition into peatlands, creating new natural carbon storage systems and to some extent mitigating carbon losses from degrading peatlands in southern regions.

New research explains why Hurricane Harvey intensified immediately before landfall

A new study explains the mechanism behind Hurricane Harvey’s unusual intensification off the Texas coast and how the finding could improve future hurricane forecasting.

Cracks herald the calving of a large iceberg from Petermann Glacier

Cracks in the floating ice tongue of Petermann Glacier in the far northwest reaches of Greenland indicate the pending loss of another large iceberg. Glaciologists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany report in a new study that the glacier’s flow rate has increased by an average of 10 percent since the calving event in 2012, during which time new cracks have also formed – a quite natural process.

Climate change may push Santa Ana fire season into winter months

Climate models predict a narrowing of the Santa Ana season in tandem with the wet season in Southern California over the next century, which could leave vegetation dry and fire-prone as winds peak in December and January, according to a new study.
