Global Analysis of How Effective and Topographic Catchment Areas Differ

Topographically sketched catchment areas are a spatial unit based on the shapes of the earth's surface. They show how human activities and climate change influence the available quantities of water. ...

Wildfire on the Rise Since 1984 in Northern California's Coastal Ranges

High-severity wildfires in northern coastal California have been increasing by about 10 percent per decade since 1984, according to a new ...

0.5°C of Additional Warming Has a Huge Effect on Global Aridity

In a simulation study, researchers showed that limiting global warming to 1.5°C rather than 2°C will mitigate aridification in some regions of the world including the Mediterranean, western Europe, ...

Global Warming Is Changing Our Plant Communities

In a comprehensive study of nearly 20,000 species, research shows that plant communities are shifting to include more heat-loving species as a result of climate ...

Forest Growth in Drier Climates Will Be Impacted by Reduced Snowpack

A new study suggests that future reductions in seasonal snowpack as a result of climate change may negatively influence forest growth in semi-arid climates, but less so in wetter ...

Predicting Drought in the American West Just Got More Difficult

A new study of more than 1,000 years of North American droughts and global conditions found that forecasting a lack of precipitation is rarely ...

Small Trees Offer Hope for Rainforests

Small trees that grow up in drought conditions could form the basis of more drought-resistant rainforests, new research ...

Exploring the Sustainability of the Indian Sugar Industry

Researchers analyzed the interconnected food, water and energy challenges that arise from the sugar industry in India - the second-largest producer of sugar worldwide - and how the political economy ...

What Happens in Vegas, May Come from the Arctic?

Ancient climate records from Leviathan Cave, located in the southern Great Basin, show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular ...

Using Techniques from Astrophysics, Researchers Can Forecast Drought Up to Ten Weeks Ahead

Researchers have developed a system which can accurately predict a period of drought in East Africa up to ten weeks ...

Where Is the Water During a Drought?

In low precipitation periods - where and how is the limited available water distributed and what possibilities are there for improving retention in the soil and the landscape? Researchers discovered ...

River Plants Counter Both Flooding and Drought to Protect Biodiversity

'Water plants are a nuisance in streams, blocking the flow. You should remove them'. This notion has for many years determined how streams were managed to prevent flooding during high ...

Heat Stress: The Climate Is Putting European Forests Under Sustained Pressure

No year since weather records began was as hot and dry as 2018. A first comprehensive analysis of the consequences of this drought and heat event shows that central European forests sustained ...

29,000 Years of Aboriginal History

The known timeline of the Aboriginal occupation of South Australia's Riverland region has been vastly extended by new research. Radiocarbon dating of shell middens - remnants of meals eaten long ...

Climate Change Will Cause More Extreme Wet and Dry Seasons

The world can expect more rainfall as the climate changes, but it can also expect more water to evaporate, complicating efforts to manage reservoirs and irrigate crops in a growing world, according ...

Satellite Data Show Severity of Drought Summers in 2018 and 2019

Measurements by the GRACE-FO satellite mission show a decline in water storage in Central Europe by up to 94 percent compared with seasonal fluctuations. The changes are so serious that a recovery ...

Daytime Aardvark Sightings Are a Sign of Troubled Times

New research reveals what a shift from night-time to daytime activity means for the well-being of aardvarks in a warming and drying ...

Texas Will Face Driest Conditions of the Last 1,000 Years

Texas' future climate will feature drier summers and decreasing water supplies for much of the state for the remainder of the 21st century -- likely resulting in the driest conditions the state ...

Tree Rings Show Unprecedented Rise in Extreme Weather in South America

A new South American Drought Atlas reveals that unprecedented widespread, intense droughts and unusually wet periods have been on the rise since the mid-20th ...

Desert Algae Shed Light on Desiccation Tolerance in Green Plants

Deserts of the US Southwest are extreme habitats for most plants, but, remarkably, microscopic green algae live there that are extraordinarily tolerant of dehydration. After completely drying out, ...

To Listen Is to Survive: Unravelling How Plants Process Information

Researchers mapped the signaling network in plants and discovered novel insights about how plants process information about their environment. This gives new potential to strategies to protect crops ...

Plant Tissue Engineering Improves Drought and Salinity Tolerance
