DEP’s first scientific report on climate change summarizes the current state of knowledge regarding the effects of climate change on New Jersey’s environment to inform state and local decision-makers as they seek to understand and respond to the impacts of climate change. This report identifies and presents the best available science and existing data regarding the current and anticipated environmental effects of climate change globally, nationally, and regionally.
New Jersey produced a comprehensive report on the impacts of climate change on human health and communities by adding a human health addendum to its 2020 New Jersey Scientific Report on Climate Change. Understanding how these new environmental challenges will directly and indirectly affect New Jersey residents is essential to establishing strategies that can effectively and equitably protect and improve health outcomes throughout our State.
The Urban Heat Island (UHI) Effect is a known phenomenon where urbanized areas (such as cities) are disproportionally hotter compared to rural areas. Causes for the UHI effect include lack of vegetation and water bodies, an abundance of hard and dry surfaces that can absorb and retain sunlight such as buildings and sidewalks, and heat generated through human activities (such as driving vehicles, using equipment or tools). In addition, humid and densely populated areas often experience the greatest difference in temperatures between urban and non-urban places. To identify these UHI areas throughout New Jersey, NJDEP used Landsat 8 and 9 satellite imagery provided by the United States Geological Survey (USGS), and developed a web application to visualize land surface temperature (LST) values for New Jersey from the summer of 2022. This web app allows users to view the surface temperature values within specific areas of interest (address, municipality, county) at a resolution of approximately 1002 ft, and land surface temperature within and surrounding New Jersey’s designated overburdened communities OBCs.
The NJDEP has released two studies by the Northeast Regional Climate Center, a National Oceanic and Atmospheric Administration (NOAA) partner, confirming increases in precipitation across New Jersey over the last 20 years, and projecting further increases in precipitation intensity through the end of this century due to climate change.
The studies, links below, are fill in 20 years of climate data gaps and provide rainfall projections through mid and late century. These studies are authored by Dr. Arthur DeGaetano, director of the Northeast Regional Climate Center and professor of Earth and Atmospheric Sciences at Cornell University, and are peer-reviewed by DEP’s Science Advisory Board.
To visual how New Jersey will be impacted by the increases in frequency and intensity of extreme precipitation events that are expected throughout the century, check out the New Jersey Extreme Precipitation Projection Tool. The tool allows users to zoom in to local areas and view a depiction of the likely precipitation depth that would occur with various storm scenarios. Users can view a range of rainfall depths, and select options for frequencies, emission scenarios, and time periods. The tool also allows users to compare this projection with the values currently published in the NOAA Atlas 14 reference report.

Indicators are observations or calculations used to track specific conditions and trends. Climate Indicators help us understand how our environmental conditions are changing so we can plan for climate impacts.
New Jersey’s climate is changing. During the last century, New Jersey has experienced rising temperatures, increased rainfall, more frequent extreme weather events and rising sea levels. These changes are the result of increasing greenhouse gas emissions in the atmosphere due to human activities such as the burning of fossil fuels (coal, oil, and natural gas), agriculture, and land clearing. The indicators discussed below are those specific to New Jersey; and are not representative of all potential indicators of climate change.

World climate scientists agree, the earth’s climate is changing due to human influences. The science linking human activities to climate change is analogous to the science linking smoking to lung and cardiovascular diseases. Over 97% of climate scientists understand that humans are causing climate change. Below is a sampling of US and International scientific experts confirming this consensus, and the need for action to mitigate and adapt to the coming impacts. This is not an exhaustive list, and those with an interest for more information are encouraged to visit the sites provided.
“The scientific evidence is clear: Global Climate Change caused by human activities is occurring now, and it is a growing threat to society.” AAAS Board Statement on Climate Change (2006)
“Global climate change will not reverse itself without serious, sustained leadership from every nation in the world community. Its impacts on human health, world hunger, international conflicts, and macroeconomics will steadily grow unless meaningful action is taken to lessen its profound effects. The United States is a major contributor to worldwide carbon dioxide emissions and today’s announcement is a significant blow to efforts to stem the tide of climate change.” AAG Statement on U.S. Withdrawal from the Paris Agreement (2017)
“Human-induced climate change requires urgent action. Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes”. Human-Induced Climate Change Requires Urgent Action (2013)
“It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide.” Climate Change: An Information Statement of the American Meteorological Society (2012)
“The scientific understanding of climate change is now sufficiently clear to justify taking steps to reduce the amount of greenhouse gases in the atmosphere.” Understanding and Responding to Climate Change (2005)
“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen. IPCC Fifth Assessment Report, Summary for Policymakers (2014)
The U.S. Global Change Research Program is comprised of 14 federal agencies working together to conduct research on global change and the impact posed on society “[t]o build a knowledge base that informs human responses to climate and global change through coordinated and integrated Federal programs of research, education, communication, and decision support.” Global Change Vision, Mission, & Strategic Plan
“The global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases. Human ‘fingerprints’ also have been identified in many other aspects of the climate system, including changes in ocean heat content, precipitation, atmospheric moisture, and Arctic sea ice.” Global Climate Change Impacts in the United States (2009)
Climate Change Impacts in the United States (2014)
“Climate change is one of a number of global changes affecting society, the environment, and the economy; others include population growth, land use change, air and water pollution, and rising consumption of resources by growing and wealthier global population”
“Because environmental, cultural, and socioeconomic systems are tightly coupled, climate change impacts can either be amplified or reduced by cultural and socioeconomic decisions.”
“While some climate changes will occur slowly, and relatively gradually, others could be rapid and dramatic, leading to unexpected breaking point in natural and social systems.”
“In the Northeast, communities are affected by heat waves, more extreme precipitation events, and coastal flooding due to sea level rise and storm surge.”
“Coastal Lifelines, such as water supply infrastructure and evacuation routes are increasingly vulnerable to higher sea levels and storm surges, inland flooding and other climate-related changes.”
“The oceans are currently absorbing about a quarter of human-caused carbon dioxide emissions to the atmosphere and over 90% of the heat associated with global warming, leading to ocean acidification and the alteration of marine ecosystem.”

Climate Change Global Food Security and the U.S. Food System (2015)
“The Potential of climate change to affect global food security is important for food producers and consumers in the United States.”
“Climate change risks extend beyond agricultural production to other elements of global food systems that are critical for food security including the processing, storage, transportation, and consumption of food.”
The Impacts of Climate Change on Human Health in the United States (2016)
“Climate change is a significant threat to the health of the American people. Rising greenhouse has concentrations result in increases in temperature, changes in precipitation, increases in the frequency and intensity of some extreme weather events, and rising sea levels. These climate change impacts endanger our health by affecting our food and water sources, the air we breathe, the weather we experience, and our interactions with the built and natural environments. As climate continues to change, the risks to human health continue to grow.”
“Conceptual diagram illustrating the exposure pathways by which climate change affects human health. Here, the center boxes list some selected examples of the kinds of changes in climate drivers, exposure, and health outcomes explored in this report. Exposure pathways exist within the context of other factors that positively or negatively influence health outcomes (gray side boxes). Some of the key factors that influence vulnerability for individuals are shown in the right box, and include social determinants of health and behavioral choices. Some key factors that influence vulnerability at larger scales, such as natural and built environments, governance and management, and institutions, are shown in the left box. All of these influencing factors can affect an individual’s or a community’s vulnerability through changes in exposure, sensitivity, and adaptive capacity and may also be affected by climate change.”
“The diagram shows specific examples of how climate change can affect human health, now and in the future. These effects could occur at local, regional, or national scales. The examples listed in the first column are those described in each underlying chapter’s exposure pathway diagram. Moving from left to right along one health impact row, the three middle columns show how climate drivers affect an individual’s or a community’s exposure to a health threat and the resulting change in health outcome. The overall climate impact is summarized in the final gray column. For a more comprehensive look at how climate change affects health, and to see the environmental, institutional, social, and behavioral factors that play an interactive role in determining health outcomes, see the exposure pathway diagrams in chapters 2-8 in the full report.”
“Vector-borne diseases are illnesses that are transmitted by vectors, which include mosquitoes, ticks, and fleas. These vectors can carry infective pathogens such as viruses, bacteria, and protozoa, which can be transferred from one host to another. The seasonality, distribution are influenced significantly by climate factors, primarily high and low temperature extremes and precipitation patterns. Climate change is likely to have both short and long-term effects on vector borne disease transmission and infection patterns.”
“Maps show the reported cases of Lyme disease in 2001 and 2014 for the areas of the country where Lyme disease is most common (the Northeast and Upper Midwest). Both the distribution and the numbers of cases have increased (see Ch. 5: Vector Borne Diseases). (Figure source: adapted from CDC 2015)”
