Summary: The impacts of rapid warming in the Arctic include earlier spring snowmelt, reduced sea ice, widespread glacier retreat, warmer permafrost, and drier landscapes.

Summary: Rising temperatures are changing processes that control the buildup and melt of snowpack, the growth or decline of glaciers, and the timing and quantity of streamflow in the Arctic.

This map show the locations of Hawai'i and U. S.-Affiliated Pacific Islands, and highlights U. S. Exclusive Economic Zones and Marine National Monuments (MNM). Map by Laura Brewington, 2016. Used with ...

Summary: Climate change—especially sea level rise, altered rainfall patterns, and rising ocean and air temperatures—impairs access to clean water and healthy food, undermines human health, threatens cultural resources and the built environment, exacerbates inequities, and disrupts economic activity and diverse ecosystems in Hawaiʻi and the US-Affiliated Pacific Islands. Adaptation efforts that build upon community strengths and center local and Indigenous Knowledge systems improve resilience.

Summary: The impacts of reduced sea ice include severe coastal erosion, isolation for rural villages, and reduced habitat for wildlife.

Summary: Loss of sea ice, thawing permafrost, and other climate-driven changes in Alaska are transforming ecosystems, disrupting cultural practices, harming fisheries and other livelihoods, exacerbating health disparities, and placing infrastructure at risk. Rapid climate changes also threaten national security. Adaptation efforts are underway across the state, but their effectiveness will depend on substantial investment and capacity building in the communities most at risk.

Summary: This secure GIS-based interactive mapping application incorporates information from many sources into a single visual environment for enhanced situational awareness, assessment, and management of resources for planning and response to natural, man-made, or pandemic events.

Summary: These assessments provide a consistent, baseline assessment of climate change impacts to water supply and demand across the West, and complement the Basin Studies and Landscape Conservation Cooperatives within the WaterSMART Initiative.

Summary: Access maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including Alaska, Hawai'i, and Puerto Rico.

The ozone hole didn't cause global warming, but climate and the ozone hole are related in other ways.
