The Third National Climate Assessment Release (NCA) report was released today. The report was written by 240 authors who worked in author teams reflecting their expertise, who also selected additional contributing authors, including several scientists and experts from USDA.
The report is similar in many respects to previous climate assessments. The authors conclude that climate change is already happening across the United States. The report documents ways climate change is altering agriculture and forestry systems across the country and evaluates how these systems are likely to be affected in the future.
The authors found that climate disruptions to agricultural production have increased in the past forty years and are projected to increase over the next twenty five years. By mid-century and beyond, these impacts will be increasingly negative on most crops and livestock. Read more »

The climate statistics for the first month of 2014 have been impressive. Extreme weather has lashed the United States from Alaska to Florida with record warmth, cold, dry and wet conditions all at the same time. The National Climatic Data Center reports that January of 2014 was the driest January on record for New Mexico, 2nd driest for Arizona and 3rd driest for California. January 2014 was also in the top ten of coldest Januaries on record for much of the upper Midwest.
Extreme drought conditions in the western U.S. are dramatically impacting water supplies critical to agriculture and elevating fire risk across our National Forests. Across the continent frequent cold waves have repeatedly threatened winter crops across the Southeast while frost depths reaching several feet will impact springtime planting across the Midwest. This kind of winter gets everyone talking about the weather. It brings to mind the quote “Everybody talks about the weather, but nobody does anything about it,” often attributed to Mark Twain (but apparently said by a friend). Read more »

As we celebrate Earth Day and think about ways to protect our environment, we cannot ignore the dramatic effects that climate change is having on our planet.
To help the U.S. Forest Service respond to a changing climate, the Climate Change Resource Center, an online portal to credible, relevant and timely information focused on forest management responses to climate change, recently released a new education resource on basic climate change science and climate modeling.

What's underneath? Healthy soil has amazing water-retention capacity. USDA's Natural Resources Conservation Service is celebrating Earth Day by highlighting the importance of soil health.
Earth Day is next Tuesday. To meet the growing sustainability challenges of the 21st Century, USDA’s Natural Resources Conservation Service (NRCS) is reminding people that many of the solutions are right at our feet — in the soil.
Here are the top five reasons NRCS says why on Earth Day 2014 you should “root” for soil health farmers: Read more »
The U.S. Forest Service has burned more than 480 acres in the Flying J Project, an effort on the Kaibab National Forest in Arizona to protect the community of Tusayan. The project is outside the Grand Canyon National Park and represents a small part of a larger effort to use controlled burns on more than 4,500 acres of the forest. So far, nearly 1,900 acres have been treated. (U.S. Forest Service/Holly Krake)
The loss of property and firefighters during wildfires are a reminder of the challenges we face in reducing the risks associated with large, unpredictable wildfires. Climate change, drought, insect infestations, changing land-use patterns, and other factors have contributed to increases in the complexity and in the numbers of wildfires across the United States.
Over the past four decades, some states such as Arizona and Idaho have seen the number of large fires burning each year more than triple. In many other western states, including California, Colorado, New Mexico, Nevada, and Wyoming, the number of large fires has doubled, according to a report by Climate Central. Average spring and summer temperatures across 11 Western states have increased by more than 1.5 degrees Fahrenheit, contributing to higher wildfire risks. In Arizona, spring temperatures have warmed faster than any other state in the U.S., rising nearly 1 degree per decade since 1970, which likely played a role in the increasing number of fires in the state.

Note: Three projects funded by a USDA Conservation Innovation Grant were recently honored by the American Carbon Registry for innovative approaches to environmental stewardship. The winners included Ducks Unlimited, Delta Institute and Terra Global Capital. Ducks Unlimited’s work aimed to generate a carbon credit system for North Dakota landowners, which not only reduces greenhouse gas emissions but also restores wetlands and grasslands that are crucial to waterfowl. Delta Institute is working with farmers to reduce use of nitrogen – one of the largest sources of greenhouse gas emissions. Finally, Terra Global Capital and many others partners are working on a credit system for rice growers in California and the Midsouth. The below post provides more information on this project.
USDA is helping to provide rice growers in California and the Midsouth with new opportunities to voluntarily execute conservation practices that reduce greenhouse gas emissions while cultivating a new income stream.
The California and Midsouth rice projects are funded by a Conservation Innovation Grant from USDA’s Natural Resources Conservation Service, which is providing more than $1 million to help identify and develop new conservation methods. The grant also leverages new and emerging ecosystem income for landowners while addressing climate change. Read more »
