Summary: High-tide flooding—which has also been called nuisance or sunny-day flooding—causes short-term public inconveniences such as flooded streets and closed roads. Over longer periods, chronic flooding can strain city budgets and compromise infrastructure. As global sea level rises, so will the frequency and depth of high-tide flooding.

Summary: Inland flooding is a common result of landfalling coastal storms. Additionally, heavy precipitation events have increased across the nation, and these events can increase risks for inland flooding.

Summary: Abnormally high water levels pushed ahead of tropical storms or hurricanes can surge onto land. The pulse of seawater delivered onto the coast can result in extreme coastal and inland floods. Under some conditions, storm surge can cause even more damage than the storms that produce them.

Variability in snowpack across the mountain ranges of the U.S. West at the start of the warm season can translate into big differences in fire risk and summer water stress.

Jeanine Jones, Interstate Resources Manager for the California Department of Water Resources, talks about the state's ongoing drought conditions and planning for California's water future.

Summary: Climate change is harming physical, mental, spiritual, and community health through the increasing frequency and intensity of extreme events, higher incidences of infectious and vector-borne diseases, and declines in food and water security. These impacts worsen social inequities. Emissions reductions, effective adaptation measures, and climate-resilient health systems can protect human health and improve health equity.

Summary: Climate change—especially shifts in precipitation, air temperature, and soil moisture—is disrupting agricultural production and food systems, and is projected to reduce the availability and affordability of nutritious food. Impacts are distributed unevenly, with farmworkers, subsistence-based communities, and rural populations facing increasing risks. Opportunities that leverage agroecological approaches can limit emissions from agriculture and improve the resilience of rural communities.

Summary: Human well-being is dependent on natural and managed ecosystems, which provide crucial functions and resources for nearly everything we eat, make, and do. Clean water and air, soils and nutrients for food production, timber for construction, and other supplies and services we depend on all come from nature. But many ecosystems are increasingly facing climate risks and impacts that alter ecological processes and functions and affect species across all levels of the food web.

Summary: Climate impacts, including rising sea levels and shifting storm patterns, are transforming coastal landscapes and undermining the resilience of communities and ecosystems. Proactive community-led adaptation strategies, including nature-based solutions and planned relocation, can help communities adapt to both current and future increases in the severity of coastal hazards across the nation.
