As emissions of heat-trapping bases accumulate in our atmosphere, Earth's polar regions are warming more quickly than at lower latitudes. The rapid environmental changes that result from this warming can have a significant impact on the physical and mental health of rural Alaskans: unpredictable weather and changes in the seasons have made harvesting food more difficult, hazardous, and stressful. The risk of physical injury has also increased, as poor ice, extreme weather, and coastal erosion bring new travel hazards. Increasingly difficult harvest conditions for fish, shellfish, berries, caribou, and sea mammals have also increased concerns about food security. Additionally, declines in snow pack, the threat of drought, changes in lake and river conditions, and damage and disruptions to community water systems have prompted concerns of water security. The climate-related challenge faced by Alaska’s tribal health system is to recognize new health stressors and community vulnerabilities, and then find healthy adaptation strategies in an increasingly uncertain future.

In 2012, water managers in Fredericktown, Missouri, saw their city's main source of water dwindle. They used the EPA’s Climate Ready Water Utilities program to consider options and develop plans to protect their water source.

Following a victory at the Battle of Trenton on December 26, General Washington and his army moved north to Princeton, New Jersey on January 3, 1777, where they surprised the British forces. This resource provides a background on the battle and how it changed the course of the American Revolution.

The Americans crossed the Delaware River on December 25, 1776 and attack Trenton the following day. Over a ten-hour period, 2,400 soldiers, 18 cannon and 100 horses crossed the frigid waters on ferries from Pennsylvania to New Jersey.
