Climate Extremes in Agriculture and Forests
-
Atmospheric CO2 in the atmosphere is now likely higher than at any point in the last two million years. The effects of elevated atmospheric CO2 are interconnected, leading to changes in extremes in both weather and climate. USGS's Dr. Adam Terando discusses the consequences of changes in temperature, precipitation and drought to U.S. agriculture and forests, and approaches to adaptation.

Coastal habitats shield people and property from sea-level rise and storms
-
Extreme weather, sea-level rise and degraded coastal ecosystems are placing people and property at greater risk of damage from coastal hazards 1–5. The likelihood and magnitude of losses may be reduced by intact reefs and coastal vegetation 1, especially when those habitats fringe vulnerable communities and infrastructure. Using five sea-level-rise scenarios, we calculate a hazard index for every 1 km2 of the United States coastline. We use this index to identify the most vulnerable people and property as indicated by being in the upper quartile of hazard for the nation’s coastline. The number of people, poor families, elderly and total value of residential property that are most exposed to hazards can be reduced by half if existing coastal habitats remain fully intact. Coastal habitats defend the greatest number of people and total property value in Florida, New York and California. Our analyses deliver the first national map of risk reduction owing to natural habitats and indicates where conservation and restoration of reefs and vegetation have the greatest potential to protect coastal communities.

Columbia Water Center White Paper America’s Water Risk: Water Stress and Climate Variability
-
The emerging awareness of the dependence of business on water has resulted in increasing awareness of the concept of “Water Risk” and the diverse ways in which water can pose threats to businesses in certain regions and sectors. Businesses seek to secure sustainable income. To do so, they need to maintain a
competitive advantage and brand differentiation. They need secure and stable supply chains. Their exposure risks related to increasing scarcity of water can come in a variety of forms at various points in the supply chain. Given increasing water scarcity and the associated deterioration of the quantity and quality of water sources in many parts of the world, many “tools” have been developed to map water scarcity riskor water risk. Typically, these tools are based on estimates of the average water supply and demand in each unit of analysis.Often, they are associated with river basins, while business is associated with cities or counties. They provide a useful first look at the potential imbalance of supply and demand to businesses.

Comment: Don’t judge species on their origins
-
SUMMARY: Conservationists should assess organisms on environmental impact rather than on whether they are natives, argue Mark Davis and 18 other ecologists. FROM THE TEXT: Nativeness is not a sign of evolutionary fitness or of a species having positive effects.The insect currently suspected to be killing
more trees than any other in North Americais the native mountain pine beetle Dendroctonus ponderosae. Classifying biota according to their adherence to cultural standards of belonging, citizenship, fair play and
morality does not advance our understanding of ecology. Over the past few decades, this perspective has led many conservation and restoration efforts down paths that make little ecological or economic sense

Conservation VALUE OF ROADLESS AREAS FOR VULNERABLE FISH AND Wildlife Species in the Crown of the Continent Ecosystem, Montana
-
The Crown of the Continent Ecosystem is one of the most spectacular landscapes
in the world and most ecologically intact ecosystem remaining in the
contiguous United States. Straddling the Continental Divide in the heart of the
Rocky Mountains, the Crown of the Continent Ecosystem extends for >250
miles from the fabled Blackfoot River valley in northwest Montana north to Elk
Pass south of Banff and Kootenay National Parks in Canada. It reaches from
the short-grass plains along the eastern slopes of the Rockies westward nearly
100 miles to the Flathead and Kootenai River valleys. The Crown sparkles with
a variety of dramatic landscapes, clean sources of blue waters, and diversity of
plants and animals.Over the past century, citizens and government leaders have worked hard to
save the core of this splendid ecosystem in Montana by establishing world-class
parks and wildernesses – coupled with conservation of critical wildlife habitat
on state and private lands along the periphery. These include jewels such as
Glacier National Park, the Bob Marshall-Scapegoat-Great Bear Wilderness,
the first-ever Tribal Wilderness in the Mission Mountains, numerous State of
Montana Wildlife Management Areas (WMAs), and vital private lands through
land trusts such as The Nature Conservancy. Their combined efforts have
protected 3.3 million acres and constitute a truly impressive commitment to
conservation. It was a remarkable legacy and great gift …but, in the face of new
challenges, it may not have been enough.

Editorial : Half-hearted engineering
-
Climate warming is not the only consequence of rising levels of atmospheric greenhouse gases. The only way to counter all effects, including those on rainfall and ocean acidity, is to remove carbon from the climate system. Arguably, some of the most immediate impacts of a warming climate will result from shifts in global rainfall patterns. The potential threats are diverse, and include water scarcity in the lush Amazonian
rainforest; increased drought in the already parched southwestern United States; rainfall replacing snow in low-latitude mountain regions; and a rise in flooding in temperate climates. Whatever the exact outcome of
these threats, the stability of the world’s economy and ecosystem both depend on maintaining precipitation patterns more or less as they are today.

Enhancing the Climate Resilience of America’s Natural Resources
-
The President's Climate and Natural Resources Priority Agenda is the result of an interagency process to inventory and assess current policies, programs, and regulations related to climate change adaptation. The Agenda builds upon the robust climate change adaptation work already accomplished by Federal agencies and identifies significant actions moving forward. It specifically mentions how Federal agencies working to address ecosystem management issues through LCCs and other multi-stakeholder bodies will work with partners to select flagship geographic regions for which they will identify priority areas for conservation, restoration, or other investments to build resilience in vulnerable regions, enhance carbon storage capacity, and support management needs. Within 24 months, these agencies and their partners will have identified and mapped the initial list of priority areas within each of the selected geographic landscapes or regions.

The U.S. Environmental Protection Agency (EPA) today released its draft Climate Change Adaptation Implementation Plans for public review and comment. In support of President Obama’s Climate Action Plan and Executive Order on Preparing the United States for the Impacts of Climate Change announced today, the Implementation Plans provide detailed information about the actions EPA plans to take across the country to help communities adapt to a changing climate.
