New Rutgers-led assessments show the Garden State is warming, water levels are climbing faster than the global average, and everyday storms are becoming more dangerous
New Jersey is on the front lines of climate change. The latest Rutgers-based assessments show that the risks are growing faster here than in many other parts of the world. Along the coast, sea levels are rising at more than twice the global rate. This increase raises the odds of damaging floods even on sunny days. Inland, hotter temperatures and heavier downpours are already reshaping daily life, from summer heat waves to storm-driven power outages.
Seas Rising Faster Than the Global Average
A recent report led by the New Jersey Climate Change Resource Center at Rutgers finds that sea-level rise along the state’s coast is not just continuing—it is accelerating. Tide-gauge records from Atlantic City show that water levels have climbed about 1.5 feet since 1912, roughly triple the global average over the same period. That change reflects a “double whammy” for New Jersey: global ocean expansion and melting ice are raising seas worldwide, while the state’s own coastline is slowly sinking.
Looking ahead, the projections are sobering. Under current global emissions trends, the Rutgers-led assessment concludes that New Jersey is likely to see between 2.2 and 3.8 feet of sea-level rise by 2100, with the possibility of roughly 4.5 feet if ice sheets in Greenland and Antarctica melt more rapidly. Those numbers are not just abstract statistics—they translate into more routine tidal flooding, larger storm surges, and greater erosion for coastal communities from Cape May to Sandy Hook.
Flooding Is Becoming a Regular Event
The impacts of higher seas are already visible. In Atlantic City, for example, the number of days with high-tide flooding has increased from fewer than one per year in the mid-20th century to dozens of days in recent years. What used to be considered “once in a while” nuisance flooding is now a recurring problem that closes roads, damages property, and strains local infrastructure.
These changes have direct consequences for planning and investment. Higher water levels mean that storms like Hurricane Sandy, which devastated parts of the Jersey Shore in 2012, can produce more severe coastal damage in the future, even if their intensity stays the same. Local officials now need to consider sea-level rise when designing everything from stormwater systems and evacuation routes to building codes and marsh restoration projects.
A Hotter, Wetter New Jersey
Sea-level rise is only one part of the story. Rutgers climate assessments also show that New Jersey is becoming warmer and wetter overall, with sharp implications for extreme weather. Average temperatures in the state have already increased, and by 2100 annual temperatures are projected to be several degrees Fahrenheit above late 20th-century norms, depending on future greenhouse gas emissions.
Warmer air can hold more moisture, which contributes to heavier downpours. New Jersey has already seen an increase in the frequency of intense rainfall events that overwhelm drainage systems, flood basements, and wash out roads. The same trends are expected to make hurricanes and tropical storms capable of bringing more extreme rainfall, even as they move inland and weaken
Everyday Weather, Escalating Risks
For residents, these shifts show up in both headline-making disasters and subtler, cumulative stresses. More frequent heat waves increase the risk of heat-related illness, especially for vulnerable populations such as older adults, outdoor workers, and people without access to air conditioning. Heavier rains and coastal flooding can disrupt transportation, damage homes and small businesses, and strain critical systems like water treatment and the electric grid.
A Rutgers summary on climate impacts in New Jersey emphasizes that these hazards do not occur in isolation. When a major storm strikes during already high tides, or when extreme heat coincides with poor air quality, the combined effects can ripple through communities and amplify existing inequalities. In many cases, the neighborhoods most exposed to flooding or heat are also those with fewer resources to prepare and recover.
Planning for a Changing Coast and Climate
Because future risks depend heavily on decisions made today, Rutgers scientists and partners across the state are working to translate this climate science into practical guidance. Sea-level rise reports from the New Jersey Science and Technical Advisory Panel provide localized projections that help towns, engineers, and state agencies plan new infrastructure with future water levels in mind. Similarly, statewide climate assessments lay out expectations for heat, rainfall, and storms to support adaptation planning in sectors ranging from public health to transportation.
At the same time, the research highlights that cutting global greenhouse gas emissions can still meaningfully alter New Jersey’s long-term trajectory. Lower-emissions pathways would limit both the magnitude of sea-level rise and the severity of future warming, reducing the burden on communities that are already on the front lines. As the science becomes clearer, the challenge now lies in turning projections into action—before today’s “extreme” events become tomorrow’s normal.
