Late rainy season reliably predicts drought in regions prone to food insecurity
Top: Whisker plots describing the variability of correlation between timing of onset of the rainy season (onset date) and peak NDVI (indicator of drought) in the following months for East, West, and Southern Africa based on Acute Food Insecurity (AFI) risks (Table 1). Bottom: Scatter plots of standardized anomaly of onset date timing and peak […]
Scientists find the error source of a sea-ice model varies with the season
IMAGE: Schematic diagram of the sea-ice simulation error sources of a regional configuration of MITgcm. view more Credit: Yue Sun Arctic sea ice has been rapidly declining in recent decades, and changes in arctic sea ice can have a significant impact on global weather and climate through interactions with the atmosphere and oceans. In addition, the […]
How Some Trees Survive the Summer Dry Season
An important component of Earth’s hydrologic cycle is transpiration—the movement of water through plants. Because transpiration affects near-surface temperatures, streamflows, and the productivity of ecosystems, understanding potential sources of subsurface moisture and how plants use them is crucial for developing accurate dynamic vegetation and land surface models. Our knowledge of these processes, however, […]
Australia’s Most Extreme Bushfire Season, Statistically Speaking
Bushfires are a natural part of Australia’s environment, but this past fire season was particularly catastrophic. It began early, at the end of the country’s hottest and driest year on record, in September 2019. By February 2020, fires had burned more than 12 million hectares, killing more than 1 billion animals and at […]
The best and safest ways to donate food and time this holiday season
Volunteering and donating money are two things your community food pantry needs more than ever. (Joel Muniz/Unsplash/) This Thanksgiving is definitely one of the weirdest in recent years. Not just because of a tumultuous election or shockingly warm weather, but because many people across the US will not be able to share turkey and stuffing […]

Hurricane season surges on as Eta slams Nicaragua and Honduras
Hurricane Eta colliding with Central America on November 3, 2020. (NHC/NOAA/) The 28th storm of the Atlantic hurricane season is currently battering Nicaragua, Honduras, and much of the rest of Central America as a Category 4 hurricane. Most of the region is expecting upwards of six inches of rain, but Nicaragua and Honduras will receive […]
Malaria parasites adapt to survive the dry season — ScienceDaily
The main parasite that causes malaria can alter its gene expression to survive undetected in the human blood stream, new research has shown. A team of international researchers, including Dr Mario Recker from the University of Exeter, has studied how the parasite, Plasmodium falciparum, can lie seemingly dormant during unfavourable conditions. The study explains how […]
