Climate change hotspots in the United States
-
We use a multi-model, multi-scenario climate model ensemble to identify climate change hotspots in the continental United States. Our ensemble consists of the CMIP3 atmosphere-ocean general circulation models, along with a high-resolution nested climate modeling system. We test both high (A2) and low (B1) greenhouse gas emissions trajectories, as well as two different statistical metrics for identifying regional climate change hotspots. We find that the pattern of peak responsiveness in the CMIP3 ensemble is persistent across variations in GHG concentration, GHG trajectory, and identification method. Areas of the southwestern United States and northern Mexico are the most persistent hotspots. The high-resolution climate modeling system produces highly localized hotspots within the basic GCM structure, but with a higher sensitivity to the identification method. Across the ensemble, the pattern of relative climate change hotspots is shaped primarily by changes in interannual variability of the contributing variables rather than by changes in the long-term mean

Climate Change Hurts Indian Tribes Disproportionately, Report Finds
-
North American Indian Tribes are especially harmed by climate change, as more ecological shifts and more frequent, more extreme weather events occur, a new study concludes. Because Tribes are heavily dependent on natural resources, severe weather events like droughts, floods, wildfires, and snowstorms make tribal communities particularly vulnerable and impact American Indians and Alaska Natives more than they impact the general population.

Climate Change Impact: Food Systems, Food Security, and Global Linkages
-
Food systems both impact and are affected by climate change. Emissions come not only from farming, but also from the processing, manufacturing, distribution, storage, sale, and preparation of food, and the disposal of food wastes. Likewise, climate change influences not just agriculture, but activities that occur throughout this larger system. In this talk, Dr. Peters will address the fundamental concepts of food systems and food security. He will explain how scientists estimate climate emissions from individual supply chains and from whole food systems. He will also consider case study examples of strategies for reducing emissions viewed both from the production and consumer ends of the food system.

Climate change impacts on the biophysics and economics of world fisheries
-
Global marine fisheries are underperforming economically because of overfishing, pollution and habitat degradation. Added to these threats is the looming challenge of climate change. Observations, experiments and simulation models show that climate change would result in changes in primary productivity, shifts in distribution and changes in the potential yield of exploited marine species, resulting in impacts on the economics of fisheries worldwide. Despite the gaps in understanding climate change effects on fisheries, there is sufficient scientific information that highlights the need to implement climate change mitigation
and adaptation policies to minimize impacts on fisheries.

Climate Change Puts Children in Jeopardy
-
From the text: Experts several years ago sounded the alarm on climate change’s potential harm to human health in the years to come. But the impact on a particularly vulnerable group—children—has not received a great deal of attention.

Climate Change Vulnerability Assessments Project Update
-
This presentation from Lesley Sneddon of NatureServe provides an update to the Steering Committee on a Appalachian LCC funded research project. Research is compiling climate change vulnerability assessments and other relevant information on vulnerable species and habitats, discerning the various methodologies and criteria used in these assessments, and using a team of expert peer reviewers to recommend the most efficient, effective, and appropriate methods for adoption by the Appalachian LCC for conservation and adaptation planning. The recommended method will then be deployed, resulting in vulnerability assessments for a suite of key species/habitats selected in consultation with partners of the Appalachian LCC.

Climate Change Vulnerability Previous Habitat Assessments
-
Research compiled the results of habitat assessments from five previous research projects. These include two projects in the Central Appalachian and Cumberland - Southern Appalachian portion of the LCC; habitat assessments completed in the North Carolina portion of the Cumberland - Southern Appalachian subregion; habitat assessments in the northeastern portion of the Central Appalachian subregion; and a draft assessment for a habitat in the Interior Low Plateau.
