Humans may devote resources to deal with climate changes that are already unavoidable, including improving levees to withstand rising sea levels, designing buildings to handle higher temperatures, and constructing dams to store water that previously was held in mountain snowpacks.

After unusually severe spring tides devastated this region in 1953, the Dutch built an elaborate system of dikes, canals, dams bridges, and locks to hold back the North Sea.

Article: CDM - Clean Development Mechanism Last Updated on 2011-06-14 00:00:00
The Clean Development Mechanism (CDM) is one of the market-based mechanisms under the Kyoto Protocol used by Countries with commitments under the Protocol to limit or reduce their greenhouse gas emissions (GHGs) in order to meet their emission targets. It has been operational since the beginning of 2006. As of mid-2011, there were 6,292 projects in the CDM pipeline (see CDM project cycle below).
Renewable energy projects account for nearly two-thirds of CDM projects and include such things as hydro, wind and biomass projects. Methane avoidance, landfill gas, afforestation and reforestation, and energy efficiency projec are also common CDM projects.
CDM projects are extremely similar to Joint Implementation (JI) projects, another of the market-based mechanisms under the Jyoto Protocol, with one major distinction: where the project is based. Under JI, an industrialized country... More »
America's Climate ChoicesLast Updated on 2011-05-12 00:00:00
A report released May 12, 2011, from the National Research Council reiterates the pressing need for substantial action to limit the magnitude of climate change and to prepare to adapt to its impacts.
America's Climate Choices, which builds on the four previous America's Climate Choices panel reports, reaffirms that the preponderance of scientific evidence points to human activities as the most likely cause for most of the global warming that has occurred during the last several decades. Furthermore, the risk of dangerous climate change impacts is growing with every ton of greenhouse gases emitted into the atmosphere.
America's Climate Choices makes the case for implementing strong federal policies that establish coherent national goals and incentives, and that promote strong U.S. engagement in international-level response efforts.
This title is part of the America's... More »
Colorado River water supply Last Updated on 2010-07-28 00:00:00
This curriculum module will look at the Colorado River water supply, climate issues and water extraction issues. We will study the data, the possible consequences to various user groups, and suggest solutions to adapt to and mitigate these changes.
Students will see how a changed climate can impact urban development, food security, regional economies, international relations, as well as the natural environment.
Students will be able to see how adaptation strategies and different from mitigation strategies and how these strategies can help minimize the impacts and make the Southwest region more sustainable.
