Richard Seager and Park Williams, climate scientists at Lamont-Doherty Earth Observatory, discuss how water will be affected by warmer temperatures, and how their research increases understanding of these issues.
Columbia Water Center experts argue that dam infrastructure issues must be connected to a broader conversation about America’s water resources.
As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.
The Indian state of Jharkhand has plentiful rainfall, but most of that water runs off before it can be put to use by farmers, who struggle to make a living. To help improve irrigation and crop productivity, the Centers for International Projects Trust and Ranchi’s Birsa Agricultural University turned to a simple traditional technology, “dobhas,” small ponds that can store rainwater for months at a time.
Overall global losses from natural disasters such as floods, landslides or earthquakes amount to about $300 billion annually. A rapid and early response is key to immediately address the loss of human life, property, infrastructure and business activity.
In recent years, scientists have revealed that we are depleting our global groundwater reserves at an alarming rate. Now researchers have shown that a significant share of this unsustainable water use fuels the global food trade, which means water exhaustion in supplier nations could ripple outward, causing food crises half way across globe.
Glaciers around the world have retreated at unprecedented rates and some have disappeared altogether. The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.
A number of national and local governments are tightening environmental regulations and shutting down specific mining projects, or in some cases the entire industry, due to environmental risks, including those related to water use and pollution.
