Ozone pollution in India is damaging millions of tons of the country’s major crops, according to a new study by an international team of researchers. The pollution caused losses of more than $1 billion in a single year, destroying enough food to feed an estimated 94 million people.
Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts.
Forests across western North America have been ravaged by the most extensive bark beetle attacks on record. Scientists are getting a better handle on what comes next—and the answers aren’t as straightforward as they expected.
Farmers and other stakeholders are hungry for guidance on how crops may fare as the nation’s climate evolves over the coming decades. This year’s National Climate Assessment includes new findings on agriculture and climate change that draw from collaborations between NCAR and the U.S. Department of Agriculture.
States are having to make tough decisions regarding their water use and their interaction with water. NCAR scientists are involved in collaborative projects in Colorado, Louisiana, and Oklahoma to evaluate the long-term effects of today’s decisions.
One of the largest bodies of water in the United States, the Ogallala Aquifer, lies underground. Crucial to life in the U.S. Great Plains, it's one of many aquifers around the world under stress as water demands increase. Satellite data are now painting a richer picture of how these water stores are evolving.
Days lengthen as spring arrives, but several other signs of the season are showing up earlier and earlier. Some animals and insects aren’t adapting fast enough to this "asynchrony," and there's an increasing disconnect with legal dates that govern hunting and other resource management.
A new computer modeling study from NCAR investigates how an increase in shrubs in the Arctic may affect permafrost. Over the past few decades, a warming climate has meant that the Arctic’s grassy tundra is being increasingly overtaken by shrubs.
If you’re an American, it’s tough to avoid corn. This ubiquitous starch turns up in soft drinks, compostable cups, and automobile fuel—and even plays a role in U.S. heat waves, including the intense one of 2011.
Prior to massive flooding early in 2011, long-term drought plagued the Australian state of Queensland . As part of a broad research program on cloud seeding, NCAR researchers have been steadily crunching data from a 2008–09 field project that looked into how to make the clouds drop more rain on the region.
New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.
Alaska is among the fastest-warming places on Earth, with its interior region warming the most statewide. A study by NCAR’s Shannon McNeeley looks at the vulnerability to climate change of native rural communities.
A study led by NCAR postdoctoral researcher Jia Hu and Julia Klein from Colorado State University looks at the relationship between plants, water, carbon, and climate on the Tibetan Plateau, which is warming at a rate twice that of the global average.
Last year, a team of NCAR scientists verified that the Weather Research and Forecasting model (WRF) can be used to depict seasonal snowfall in Colorado with a high degree of accuracy. Now the team is using WRF to forecast future snowfall.
Crop yields are affected by many factors, including breeding, management, and climate. New research from NCAR seeks to better understand these factors and their contributions to historical yield increases, in order to anticipate future changes.
