It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space.
NOAA’s Environmental Literacy Program (ELP) Community Resilience Education Theory of Change communicates the overarching philosophy guiding its grants program. ELP supports projects that both inspire and educate people to use Earth system science to increase ecosystem stewardship and resilience to extreme weather, climate change, and other environmental hazards.
A theory of change is broad in scope and begins with a problem statement and ends with a goal. In between, causal pathways systemically lay out the steps, or short-, mid-, and long-term outcomes that must be met to achieve the end goal.
While all people living in the United States are affected by climate change, some communities and some populations are more vulnerable to changing climate conditions than others. This final report from a NOAA-funded project in New Jersey highlights current evidence regarding impacts of changing climate-related coastal hazards on socially vulnerable populations, identify opportunities to address needs of socially vulnerable populations as part of coastal community climate resilience planning, and outlines possible options for coastal management policy that may enhance efforts to address needs of socially vulnerable populations as part of coastal community resilience efforts.
The world continues to emit greenhouse gases while the planet's climate is changing faster than ever. This report intends to take up the latest and most essential scientific findings published in an extraordinary year—the climate science year in review.
The Central Council of the Tlingit and Haida Indian Tribes of Alaska (Tlingit & Haida) is a federally recognized Indian Tribe that serves 20 villages and communities stretching over 43,000 square miles within the Alaska Panhandle. The Tlingit and Haida membership is among the largest, most isolated, and most geographically dispersed of Native or Tribal populations nationwide. The region encompasses a 525-mile strip of coastline and interior waterways, bordered by Canada on the north, south, and east, with the Gulf of Alaska on the west.
The Central Council recognizes that wild salmon, berries, clams, herring, halibut, yellow cedar and other species important for subsistence, cash and culture are at risk. In response, they have released a 53-page climate change adaptation plan. The document is a roadmap for prioritizing, monitoring, and responding to threats stemming from warming air and ocean temperatures, caused by increasing levels of greenhouse gases trapped in the atmosphere.
The Beloved Community is a vision for our future where all people share equally in the wealth and bounty of the earth, where we protect its abundance, diversity, and beauty for future generations. In this vision of liberation, racism, exploitation, and domination are replaced by democracy, cooperation, interdependence, and love. To get there, we pursue transformative, systems-change solutions. What do we mean by this? The root causes of the problems our communities face—like climate change, racism, and economic inequality—are all deeply connected. Since the problems are connected, so are the solutions. The purpose of this toolkit is to put us on the path toward achieving this vision. Through the context of building equity and resilience into climate adaptation planning, we introduce strategies to transform our communities and, by extension, society. Our ultimate goal is to create lasting and systemic change. At the same time, we recognize the urgency of the issues our communities face and the need to take action now. That is why we pursue change at every scale—from policy changes to community-based projects—to institute the transformative change we need to uphold our vision of the beloved community.

The authors of the guide also developed and included two attractive, user-friendly handouts that can be easily customized and reproduced for community outreach.
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.
The Montana Climate Assessment (MCA) synthesizes, evaluates, and shares credible and relevant scientific information about climate change in Montana with the citizens of the state. The motivation for the MCA arose from citizens and organizations in Montana who have expressed interest in receiving timely and pertinent information about climate change, including information about historical variability, past trends, and projections of future impacts as they relate to topics of economic concern. This first assessment reports on climate trends and their consequences for three of Montana’s vital sectors: water, forests, and agriculture.

Click on each state to see key messages, figures, and and a summary of climate impacts in your state.
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 report synthesizes available science on the observed and projected impacts of climate change in the Great Lakes Basin and documents the climate change assessment methods applied in the region. It was initiated in support of commitments under Annex 9-Climate Change Impacts of the Great Lakes Water Quality Agreement to take into account the climate change impacts on the chemical, physical, and biological integrity of the waters of the Great Lakes and communicate and coordinate binationally regarding ongoing developments of domestic science. The report draws upon the range of research conducted by various levels of government, academia, and other organizations and the growing body of knowledge in areas of ecological research and climate change and provides researchers, managers, and decision makers with a time-stamped, thorough, and methodical examination of that climate change science.
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.
