Key Climate Insights

The Northeast and Midwest regions have experienced the largest temperature increases over the past century, with warming of approximately 2°F since the early 1900s.
The Southwest has seen significant variability in precipitation patterns, with periods of prolonged drought.
Annual precipitation has increased across much of the Northeastern and Midwestern United States.
Western regions show a pattern of increasing temperatures and decreasing precipitation, contributing to drought conditions.
Northern regions of the US are warming faster than southern regions, consistent with global patterns of polar amplification.
Seasonal patterns are shifting, with earlier springs and longer growing seasons in many regions.
