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.

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 »
I care deeply about conserving our land, soil and water and know that farmers are incredible stewards of the land. Prior to coming to USDA, I served as CEO of the National Association of Conservation Districts. I know firsthand that improving water conservation requires innovative technologies and partnerships.
In honor of World Water Day, I spoke to the U.S. Water Partnership on the critical role conservation plays in agriculture. According to the 2012 National Intelligence Community Assessment, about 70 percent of the global fresh water supply is devoted to agriculture. USDA and its partners play an important role in ensuring that producers have the water resources necessary to produce the food, fuel and fiber needed by Americans and our trading partners around the world. It’s an important part of our mission. Read more »
The forests that cling to the steep slopes and cliffs of New Zealand’s Milford Sound are an example of the many pristine forest lands protected throughout the world (U.S. Forest Service/Robert Westover)
A world without forests would be pretty bleak. Life as we know it couldn’t exist. In fact it would, more than likely, be a dead planet. That’s because everything we take for granted; clean air and water, abundant wildlife and nearly every product we use in our daily lives, from the roof above our heads to pencils, wouldn’t exist.
It would be a challenge just to live one day without using a product derived from a tree. Aside from paper, you might not even be able to sit in a chair or desk at school or work. These things are part of our everyday existence because of forests.
Since trees are important for everyone around the world, the United Nations (U.N.) has designated every March 21 as the International Day of Forests. Read more »
