The warming of the Earth has been the subject of intense debate and concern for many scientists, policy-makers, and citizens for at least the past decade. Climate Change Science: An Analysis of Some Key Questions, a new report by a committee of the National Research Council, characterizes the global warming trend over the last 100 years, and examines what may be in store for the 21st century and the extent to which warming may be attributable to human activity.

The social cost of carbon (SC-CO2) is an economic metric intended to provide a comprehensive estimate of the net damages - that is, the monetized value of the net impacts, both negative and positive - from the global climate change that results from a small (1-metric ton) increase in carbon-dioxide (CO2) emissions. Under Executive Orders regarding regulatory impact analysis and as required by a court ruling, the U.S. government has since 2008 used estimates of the SC-CO2 in federal rulemakings to value the costs and benefits associated with changes in CO2 emissions. In 2010, the Interagency Working Group on the Social Cost of Greenhouse Gases (IWG) developed a methodology for estimating the SC-CO2 across a range of assumptions about future socioeconomic and physical earth systems. Valuing Climate Changes examines potential approaches, along with their relative merits and challenges, for a comprehensive update to the current methodology. This publication also recommends near- and longer-term research priorities to ensure that the SC- CO2 estimates reflect the best available science.

In September 2017, Hurricane Maria hit Puerto Rico, completely upending the energy grid of the small island. The nearly year-long power outage that followed vividly shows how the new climate reality intersects with race and access to energy. The island is home to brown and black US citizens who lack the political power of those living in the continental US. As the world continues to warm and storms like Maria become more commonplace, it is critical that we rethink our current energy system to enable reliable, locally produced, and locally controlled energy without replicating the current structures of power and control. In Revolutionary Power, Shalanda Baker arms those made most vulnerable by our current energy system with the tools they need to remake the system in the service of their humanity. She argues that people of color, poor people, and indigenous people must engage in the creation of the new energy system in order to upend the unequal power dynamics of the current system. Revolutionary Power is a playbook for the energy transformation complete with a step-by-step analysis of the key energy policy areas that are ripe for intervention. Baker tells the stories of those who have been left behind in our current system and those who are working to be architects of a more just system. She draws from her experience as an energy-justice advocate, a lawyer, and a queer woman of color to inspire activists working to build our new energy system. Climate change will force us to rethink the way we generate and distribute energy and regulate the system. But how much are we willing to change the system? This unique moment in history provides an unprecedented opening for a deeper transformation of the energy system, and thus, an opportunity to transform society. Revolutionary Power shows us how.
