climate change

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.

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.

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.

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.

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.

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.

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, 2^nd driest for Arizona and 3^rd 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).

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.

Earth Day is next Tuesday.  To meet the growing sustainability challenges of the 21^st 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:

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.
