Global warming is unequivocal
and primarily human-induced.
Climate changes are underway in the United States
and are projected to grow.
Widespread climate-related impacts are occurring now
and are expected to increase.
Climate change will stress water resources.
Crop and livestock production
will be increasingly challenged.
Coastal areas are at increasing risk
from sea-level rise and storm surge.
Threats to human health will increase.
Climate change will interact with
many social and environmental stresses.
