Climate Change poses significant challenges to water resources and the Environmental Protection Agency’s (EPA) National Water Program (NWP). The NWP 2012 Strategy: Response to Climate Change addresses climate change in the context of our water programs. It emphasizes assessing and managing risk and incorporating adaptation into core programs. Many of the programs and activities already underway throughout the NWP—such as protecting healthy watersheds and wetlands; managing stormwater with green infrastructure; and improving the efficiency and sustainability of water infrastructure, including promoting energy and water efficiency, reducing pollutants, and protecting drinking water and public health—are even more important to do in light of climate change. However, climate change poses such significant challenges to the nation’s water resources that more transformative approaches will be necessary. These include critical reflection on programmatic assumptions and development and implementation of plans to address climate change’s challenges.
This 2012 Strategy articulates such an approach. The reader is advised not to interpret the framing of individual strategic actions that use terms such as “encourage” or “consider” to mean that the NWP doesn’t recognize the urgency of action. Rather, we recognize that adaptation is itself transformative and requires a collaborative, problem-solving approach, especially in a resource-constrained environment. Further, “adaptive management” doesn’t imply a go-slow or a wait-and-see approach; rather, it is an active approach to understand vulnerability, reduce risk, and prepare for consequences while incorporating new science and lessons learned along the way.

Meanwhile, here’s a look at global temperatures from The New York Times. Here’s an excerpt:
For those who might be keeping score, we just passed the 333rd consecutive month of global temperatures above the 20th-century average. November 2012 was the fifth-warmest November since records began in 1880, the National Oceanic and Atmospheric Administration said in its monthly climate report. The agency calculated that the 10 warmest Novembers on record have all occurred within the past 12 years. The last time global temperatures came in below the 20th-century average for the month of November was in 1976, and the last time any month came in below the average was February 1985…
La Niña years are usually cooler than average globally, so scientists say that to have such years coming in among the top 10 warmest in the historical record is a testament to how much the climate is changing.
Finally, the USFS has released a new report, Understanding the effects of a changing climate on native trout in the Rockies. Here’s the release:
Record setting drought and temperatures like those experienced in 2012 may become the “new normal” that managers of aquatic resources in the Rocky Mountains have to contend with as the century progresses. Exploring the historical patterns and potential consequences of a changing climate on native trout habitats and populations to feed into better risk management assessments is the focus of a new study published in the science journal, Fisheries, “The Past as Prelude to the Future for Understanding 21st-Century Climate Effects on Rocky Mountain Trout.” The study was led by U.S. Forest Service Rocky Mountain Research Station Research Fisheries Biologist Daniel Isaak, with collaborators from the U.S. Geological Survey and Colorado State University’s Department of Fish, Wildlife, and Conservation Biology.
Many bioclimate models predict that large reductions in native trout populations will occur across the Rocky Mountains during the 21st century but the models lack details about how changes will occur. Long-term monitoring records from case history areas that include river basins in northwest Montana, central Idaho, the Greater Yellowstone Ecosystem, western Wyoming and southern Colorado, show trends in temperature and stream flow that suggest trout habitats have already been altered by climate change during the last 50 years. “Unfortunately, similar long-term records for trout populations are lacking so scientists are unable to confirm simultaneous changes in trout populations,” said Isaak.
The study goes on to state that local monitoring networks of biological, temperature, and stream flow data could be developed in a few years and used with new spatial stream analyses to provide high-resolution climate vulnerability assessments that would provide decision makers with “actionable intelligence” regarding where to most efficiently allocate conservation resources. These monitoring networks and vulnerability assessments could form a cornerstone for interagency collaborations and partnerships between research and management as all parties work to develop and enact the conservation strategies needed to preserve native trout in the Rocky Mountains this century.
