Climate Change in the United States: Benefits of Global Action

GHG Mitigation: Estimated Benefits to the U.S. in 2100

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
Actions can be taken now to reduce GHG emissions and avoid many of the adverse impacts of climate change. Quantifying the benefits of reducing GHG emissions (i.e., how GHG mitigation reduces or avoids impacts) requires comparing projections of climate change impacts and damages in a future with policy actions and a future without policy actions. Looking across a large number of sectors, this report communicates estimates of these benefits to the U.S. associated with global action on climate change.

Adapting To Climate Change in Coastal Parks

UNITED STATES DEPARTMENT OF THE INTERIOR
Over the next century, warming global temperatures will present many challenges for the National Park Service (NPS) and public land managers. Rising sea level will be one of the most obvious and most challenging impacts of this warming. Even a minor increase in sea level will have significant effects on coastal hazards, natural resources and assets within national parks. To begin addressing these issues, the Program for the Study of Developed Shorelines (PSDS) at Western Carolina University (WCU) has partnered with NPS to begin an assessment of the level of exposure that park owned assets will face during a period of rising sea level.

Transitioning to Low-Carbon Trucks

Tuesday, June 16th, 2015

NATIONAL CENTER FOR SUSTAINABLE TRANSPORTATION
UC DAVIS INSTITUTE OF TRANSPORTATION STUDIES
The United States and California have both made commitments to an 80% reduction in energy-related greenhouse gases (GHGs) from 1990 levels by 2050 in order to help stabilize atmospheric concentrations of greenhouse gases. These commitments do not specifically target transportation or an individual transport mode.

This white paper reviews previous studies and provides a new investigation into the feasibility of achieving an 80% reduction in CO2-equivalent (CO2e) GHG emissions in the United States and California from trucks in the 2050 time frame (“80-in-50”). We assess the technological and economic potential of achieving deep market penetrations of low-carbon vehicles and fuels, including vehicles operating on electricity, hydrogen, and biofuels.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.

Boston: Methane Emissions from Natural Gas Infrastructure

Thursday, January 29th, 2015
methane fig1

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA (PNAS)
Most recent analyses of the environmental impact of natural gas have focused on production, with very sparse information on emissions from distribution and end use. This study quantifies the full seasonal cycle of methane emissions and the fractional contribution of natural gas for the urbanized region centered on Boston. Emissions from natural gas are found to be two to three times larger than predicted by existing inventory methodologies and industry reports. Our findings suggest that natural-gas–consuming regions may be larger sources of methane to the atmosphere than is currently estimated and represent areas of significant resource loss.
