The National Centers for Environmental Information (NCEI) is the nation's scorekeeper in terms of addressing severe weather and climate events in their historical perspective. As part of its responsibility of monitoring and assessing the climate, NCEI tracks and evaluates climate events in the U.S. and globally that have great economic and societal impacts. Found on these webpages are information on the weather and climate events that have had the greatest economic impact from 1980 to 2015. The U.S. has sustained 188 weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2015). The total cost of these 188 events exceeds $1 trillion.

With the goal of creating a cleaner San Diego for future generations, the City of San Diego’s Climate Action Plan calls for eliminating half of all greenhouse gas emissions in the City and aims for all electricity used in the city to be from renewable sources by 2035. The Climate Action Plan is a package of policies that will benefit San Diego’s environment and economy. It will help create new jobs in the renewable energy industry, improve public health and air quality, conserve water, more efficiently use existing resources, increase clean energy production, improve quality of life, and save taxpayer money. The plan identifies steps the City of San Diego can take to achieve the 2035 targets, including creating a renewable energy program, implementing a zero waste plan, and changing policy to have a majority of the City’s fleet be electric vehicles. The Climate Action Plan helps achieve the greenhouse gas reduction targets set forth by the State of California. The City’s first Climate Action Plan was approved in 2005 and a commitment to update the plan was included in the City’s 2008 General Plan update.

Climate change adds uncertainty to already complex global water challenges. Though no standard method has been adopted yet by the World Bank, common practice uses downscaled precipitation and temperature projections from Global Climate Models (GCMs) as input to hydrologic models. While this has been useful in some applications, they often give too wide a dispersion of readings to provide useful guidance for site-specific water resources management and infrastructure planning and design. Rather than design for an uncertain situation selected a priori, the so-called “bottom-up” approaches explore the sensitivity of a chosen project to the effects of uncertainties caused by climate change. Supported by the Water Partnership Program, this book summarizes alternatives explored by a group of organizations that belong to the Alliance for Global Water Adaptation (AGWA), to provide practitioners with the tools to adapt to the realities of climate change by following a decision-making process that incorporates bottom-up thinking.

Intense rainstorms, floods, and heat waves will become more common in the Great Lakes region due to climate change in the coming decades. While ice-cover declines will lengthen the commercial navigation season on the lakes, warmer lake temperatures will increase risks from invasive species, and could threaten water quality. Material in this report is largely a synthesis of the information contained in the National Climate Assessment’s chapters on the Midwest (Chapter 18) and Northeast (Chapter 16). Donald Scavia, GLISA's co-director, was one of the convening authors of the NCA's Midwest regional chapter; GLISA also served as a hub for the compilation of technical inputs for the Midwest chapter.

December 2013

This report, the first of its kind for the City of Grand Rapids, outlines the condition of the city's climate resiliency and offers recommendations for how it can both impact and adapt to climate change. The report's goal is to both spur a larger community conversation around processes that will enable Grand Rapids to become a more climate-resilient city and to spur many specific short- and near-term projects, policies, programs, and plans to mitigate the effects of climate change. The report documents projected local climate changes, their potential negative impact to low-income families, and outlines small near-term solutions that the city can make to curb or adapt to climate change. Recommendations include investing in green space and improving the city's tree canopy, improving the city's energy autonomy, and implementing green street infrastructure materials and maintenance techniques.

The Resilience Measurement Index (RMI) was formulated to capture the fundamental aspects of resilience for critical infrastructure with respect to all hazards. The RMI methodology supports decision making related to risk management, disaster response, and maintenance of business continuity. It complements other indices that have been developed―the Protective Measures Index and the Consequences Measurement Index―and thus, in combination with other tools, allows critical infrastructure to be compared in terms of resilience, vulnerability, consequences, and ultimately risk.
