One of the more interesting scenarios is a sea level rise of 4 feet under similar emissions as now by 2100AD
begin quote from Google AI:
- City Analogues: Under high-emissions scenarios, individual cities will closely mirror the current climates of much hotter regions:
- Chicago, IL: Rises by 9.1°F, feeling like Montgomery, Alabama.
- New York, NY: Rises by 7.6°F, feeling like Columbia, South Carolina.
- Phoenix, AZ: Rises by 7.2°F, feeling like Al Mubarraz, Saudi Arabia.
- Los Angeles, CA: Rises by 5.8°F, feeling like Túxpam, Mexico.
- Mitchell, SD: Expected to warm the most in continental projections, up to 11.1°F.
Sea-Level Rise and Coastal Flooding
AI Overview
By 2100 AD, the U.S. climate is projected to be significantly warmer, drier in some regions, and subject to more extreme weather, with average summer high temperatures across major U.S. cities rising by roughly 7.9°F under high-emission scenarios.
Temperature Shifts
- Higher Summer Highs: Summer highs across 247 major U.S. cities are projected to increase an average of 7.9°F (4.4°C) by 2100 under high-emissions pathways, effectively shifting local summer climates 437 miles south.
- City Analogues: Under high-emissions scenarios, individual cities will closely mirror the current climates of much hotter regions:
- Chicago, IL: Rises by 9.1°F, feeling like Montgomery, Alabama.
- New York, NY: Rises by 7.6°F, feeling like Columbia, South Carolina.
- Phoenix, AZ: Rises by 7.2°F, feeling like Al Mubarraz, Saudi Arabia.
- Los Angeles, CA: Rises by 5.8°F, feeling like Túxpam, Mexico.
- Mitchell, SD: Expected to warm the most in continental projections, up to 11.1°F.

Extreme Weather and Natural Hazards
- Heatwaves: Dangerous hot days are projected to become 3 to 10 times more frequent (or up to dozens of times more common under severe pathways), straining power grids and escalating public health risks.
