The spotlight may have been on California this past summer, but groundwater reservoirs—often the back-up for surface water supplies during prolonged drought—are in decline across much of the southern United States. Meanwhile, people are using millions of gallons of water per day in regions dependent on groundwater aquifers

The Climate Prediction Center's outlook for December through February gives California a 2-in-3 chance of receiving normal precipitation or better. Cool, wet conditions are favored in some southern regions, while warm weather is favored to the west, including Alaska and Hawaii.

Warm oceans lead to record September warmth for Alaska maritime locations.

Alaska’s coastal waters are especially vulnerable to the drop in pH—acidification—that comes when excess carbon dioxide dissolves into the ocean from the atmosphere. These maps show relative risk levels for commerical and subsistence fisheries.
