This interactive visualization provides a clear, well-documented snapshot of current and projected values of several climate variables for local areas in California. The climate variables include observed and projected temperatures, projected snowpack, areas vulnerable to flooding due to sea level rise, and projected increase in wildfires. The projected values come from expert sources and well-established climate models.
This is an interactive map of California and the Sierra Nevada mountains, showing projected variations in water stored in snowpack, from 1950 to 2090, assuming low or high emission scenarios over that period of time. Interactive can be adjusted to show different months of the year and various climate models, graphed by site.
This video discusses how the populous areas west of the Andes are largely desert and rely on glacial meltwater as an important source of fresh water. Because the Peruvian glaciers high in the Andes are in rapid retreat, scientists are monitoring the steadily shrinking glaciers and the impact of their reduction on local populations.
This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.
This video documents the impact of the 2011 drought on the water supply of two Texas towns. It discusses how the higher temperatures have increased the evaporation from open reservoirs, resulting in a drop in their water levels. The use of water in fighting wildfires has also contributed to this drawdown. While some jurisdictions have been able to develop pipelines to other sources, others have had to resort to trucking water in.
National Action Plan for Managing Freshwater Resources in a Changing Climate
September 30, 2011
A plan published by the White House Climate Change Adaptation Taskforce to help freshwater resource managers assure adequate water supplies, safeguard water quality and aquatic ecosystems, and protect human life, health and property. The plan lays out six goals for effective management:
Establish a Planning Process to Adapt Water Resources Management to a Changing Climate
Improve Water Resources and Climate Change Information for Decision-Making
Strengthen Assessment of Vulnerability of Water Resources to Climate Change
Expand Water Use Efficiency
Support Integrated Water Resources Management
Support Training and Outreach to Build Response Capability
A report that considers past change over geologic time, recent evidence of accelerated rates of change, and the implications of continued climate change in Maine during the 21st century as a result of greenhouse gas emissions and their associated pollutants.
