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 »

Earth's Hot Past: Prologue to Future Climate?
Study of Earth's deep past leads to look into the future
The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes.
The study, by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl, will appear as a "Perspectives" article in this week's issue of the journal Science.
View a video interview with Jeff Kiehl of UCAR.
The work was funded by the National Science Foundation (NSF), NCAR's sponsor.
Building on recent research, the study examines the relationship between global temperatures and high levels of carbon dioxide in the atmosphere tens of millions of years ago.
It warns that, if carbon dioxide... More »
