Rivers in Northeastern have 20 fewer days of ice cover
No more ice harvesting industry on the Hudson
Warmer Weather, especially Winters

In past three years, region experienced five 100 year flood events
Intense precipitation events doubled in 30 years
Changing salt front in Hudson may impact public drinking water
Flooding likely to encourage shoreline hardening as humans respond to climate change
Intense Rains
Rising Waters More Frequent Flooding

Rising Waters
Scenarios
Y = Character of preparations
X= Amount of preparation
Less use of natural systems
LotsLittle
More use of natural systems
Stagflation rules Give Rivers Room
Procrastination Blues
Nature Be Dammed

Consumer credit issues and federal budget deficit. Rising oil and corn prices
High unemployment: NYC fares poorly
Green tech is bright spot in regional economy
Little state/federal monies for engineered solutions
Tax breaks and land use regulation used as “carrots and sticks”
Development moves to higher ground (north in Hudson Valley)
Rising Waters
Stagflation Rules
![Page 18: “ Everyone talks about the weather, but nobody does anything about it.” Mark Twain Rising Waters](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649e685503460f94b63e6f/html5/thumbnails/18.jpg)
Local climate will become more warm, wet, and wild.
Increases in extreme weather
Sea-level rise is serious long-term threat, but not likely to exceed a foot between now and 2030.
Capacity to adapt will depend on local land-use planning, new regulations of the flood plain, land protection, and smart infrastructure investments.

Improve community preparedness for extreme weather and local climate-change threats.
Prepare communities for climate change by incorporating impacts into land-use decisions
Guide future development out of flood-prone areas
Improve resilience of shorelines, natural systems, and critical infrastructure to impacts of extreme weather
Establish climate-change-adaptation funding
Apply cost-effective green technologies and use natural systems to reduce vulnerability of people and properties to flooding and heat waves
Conserve healthy forest, wetland, and river ecosystems as well as agricultural resources because they are vital to successful adaptation to climate change.

tributaries; Review regulatory incentives and viable strategic pathways What are the resources at risk? Wetlands, etc,
Overall goal: Slow down the waters; connect the floodplains
