Indiana’s climate is changing. Temperatures are rising, more precipitation is falling, and the last spring frost of the year has been getting steadily earlier. This report describes historical climate trends from more than a century of data and future projections that detail the ways in which our climate will continue to change.
Coastal flooding in the United States is already occurring and the risk of flooding is expected to grow in most coastal regions, in part due to climate change. The Centers for Disease Control and Prevention developed this booklet, aimed at the general public, that identifies steps people can take to prepare for the health risks associated with coastal flooding. The booklet answers some of the key questions about coastal flooding in a changing climate: why these events are on the rise; how it might affect health; and what people can do before, during, and after a coastal flooding event to stay safe. Scientific information used in the document is derived from peer-reviewed synthesis and assessment products, including those published by the U.S. Global Change Research Program and the Intergovernmental Panel on Climate Change, as well as other peer-reviewed sources and federal agency resources.
This user-friendly summary is based on the 2015 report “City of Long Beach Climate Resiliency Assessment Report" and “Appendices” prepared by the Aquarium of the Pacific at the request of Mayor Robert Garcia.

Climate change affects human health by making extreme heat more common, more severe, and last longer. That is expected to continue into the future. This handbook explains the connection between climate change and extreme heat events, and outlines actions citizens can take to protect their health during extreme heat. This resource builds on the 2006 Excessive Heat Events Guidebook from the Environmental Protection Agency (EPA), and includes up-to-date climate information from recent climate assessment reports, such as the 2014 Third National Climate Assessment, the 2016 Impacts of Climate Change on Human Health in the United States, and EPA’s 2016 Climate Change Indicators in the United States.
This report features observed trend data on 37 climate indicators, including U.S and global temperatures, ocean acidity, sea level, river flooding, droughts, and wildfires. It documents rising temperatures, shifting patterns of snow and rainfall, and increasing numbers of extreme climate events, such as heavy rainstorms and record high temperatures. Many of these observed changes are linked to the rising levels of carbon dioxide and other greenhouse gases in our atmosphere, caused by human activities.
Climate.gov's El Niño-Southern Oscillation—or ENSO—page provides information on the current status of El Niño and La Niña, plus links to forecasts, maps, and videos from across NOAA that help explain the impacts of the ENSO on the U.S.
In January 2015, Long Beach Mayor Robert Garcia asked the Aquarium of the Pacific to take a lead in assessing the primary threats that climate change poses to Long Beach, to identify the most vulnerable neighborhoods and segments of the population, and to identify and provide a preliminary assessment of options to reduce those vulnerabilities. Over the course of 2015, the Aquarium hosted and participated in meetings and workshops with academic and government scientists, business and government leaders, local stakeholders, and Long Beach residents to discuss key issues facing our community as the result of climate change. This report, completed in December 2015, represents the culmination of these efforts. The report offers detailed assessments of the five main threats of climate change to Long Beach: drought, extreme heat, sea level rise and coastal flooding, deteriorating air quality, and public health and social vulnerability. It also provides an overview of what is currently being done to mitigate and adapt to these threats, and other options to consider. Finally, this report presents a series of steps and actions that city leaders and community stakeholders can use as a template for making Long Beach a model of a climate resilient city.
This handbook (USGS Professional Paper 1815) was designed as a guide to the science and simulation models for understanding the dynamics and impacts of sea level rise on coastal ecosystems. Coastal land managers, engineers, and scientists can benefit from this synthesis of tools and models that have been developed for projecting causes and consequences of sea level change on the landscape and seascape.
Successfully negotiating climate change challenges will require integrating a sound scientific basis for climate preparedness into local planning, resource management, infrastructure, and public health, as well as introducing new strategies to reduce greenhouse gas emissions or increase carbon sequestration into nearly every sector of California’s economy. This Research Plan presents a strategy for developing the requisite knowledge through a targeted body of policy-relevant, California-specific research over three to five years (from early 2014), and determines California’s most critical climate-related research gaps.
