Cross-posted from the White House Blog:
Today, in a major step to advance the President’s Climate Data Initiative, the Obama administration is inviting leaders of the technology and agricultural sectors to the White House to discuss new collaborative steps to unleash data that will help ensure our food system is resilient to the effects of climate change.
More intense heat waves, heavier downpours, and severe droughts and wildfires out west are already affecting the nation’s ability to produce and transport safe food. The recently released National Climate Assessment makes clear that these kinds of impacts are projected to become more severe over this century. Read more »
This week, I visited the small town of Cameron Creek Colony in Tulare County, California and saw firsthand the challenges drought poses, particularly for those living in rural communities.
About 10 percent of Cameron Creek Colony residents have no access to water because their wells have run dry. Still others have only intermittent access to water. Many are in danger of losing access to water permanently in the near future. One long-time resident told me that until this drought, she’d never worried about water. Now, worrying about having enough water is constantly on her mind. Read more »
U.S. Forest Service planning teams must complete rapid assessments of ecosystem conditions on national forests and the effects on those ecosystems (such as this one at Cedar Lake) from stressors, such as climate change. U.S. Forest Service photo

From South Carolina’s coastal plain to the North Carolina mountains to the tropics of Puerto Rico to the southern Sierra Nevada region of California, climate change is on the minds of forest planners.
That’s because U.S. Forest Service planning teams in these areas are among the first to revise their land and resource management plans under the 2012 Planning Rule. To help them in their planning, land managers from the Francis Marion, Nantahala, Pisgah, El Yunque, Inyo, Sequoia, and Sierra national forests will turn to a web-based tool known as the Template for Assessing Climate Change Impacts and Management Options.
Forest Plans help guide the management of national forests and are typically revised every 10 to 15 years. The plans help ensure that national forests and grasslands continue to meet the requirements of the National Forest Management Act—for clean air and water, timber and other forest products, wildlife habitat, recreation and more.

Warm Fire, 2006. Over the last three decades, fire season lengths have increased by 60-80 days and annual acreages burned have more than doubled to over 7 million acres annually. In addition, growing housing development in forests has put more people and houses in harms’ way, also making firefighting efforts more expensive.

Forests significantly contribute to our quality of life, but climate change is adversely affecting natural resources in rural and urban areas across the U.S. A new report released by the White House, the National Climate Assessment, explores many related issues including how a warming planet affects our forests.
With contributions from U.S. Forest Service scientists, the report is one of the most comprehensive examinations of climate change and its effects on forested land. It concludes that a warming climate will complicate future management of public, private and tribal forests. Read more »
Farmers, ranchers and foresters have long understood the need to care for our land and water—not only because preserving those resources for our children and their children is the right thing to do, but because they know that our farms and forests are more productive and efficient when they’re properly cared for.
Science and technology has expanded our capability and improved our understanding over the years, but this core mission remains the same. Today’s farmers and ranchers have risen to the twin responsibilities of producing safe, affordable food while employing cutting edge conservation practices on their operations to conserve water, minimize runoff, prevent soil erosion, and preserve wildlife habitat. They know that this will only become more critical as we take on the challenges of feeding a growing global population and dealing with the impacts of a changing climate. Read more »

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 »
