In Austin, climate change is expected to cause hotter summers with more frequent heatwaves and fewer cold spells. Precipitation projections have high uncertainty, but the rainfall amount is expected to remain relatively unchanged. Austin is expected to experience more extremes, more variability in climate, and slight increase in windy days (fewer calm days). These projections are based on “high” and “business as usual” emission scenarios. A “high” emission scenario refers to model projections where emissions from human activities are expected to increase.
