Unconcerned

Tips from Six Americas study:

·         Emphasize local impacts (even more so than with cautious and concerned)

·         Emphasize strong scientific agreement that global warming is happening, Is human caused, and harmful to people

·         Stewardship ethic (many religious)

My recommended case study: Turtle or clownfish

Hatfield visitors (3) Say:

• 2 of 3 would use the exhibit, learn about an animal, and make a story
• Case study: 1 turtle, 1 clown fish
• Both would share but only 1 if it had audio or video
• Both wanted photos, charts, text, clip art, scientific data and expert testimony, and local effects
• 1 wanted carbon footprint calculator
• 1 said it's a topic of interest to many people, just not him personally

Myth Busters: does CO2 really warm air?

Case study: Salmon (Ocean warming, sea level rise)

Salmon

Climate change affects salmon throughout its life stages. Historically, warm periods in the coastal ocean have coincided with relatively low abundances of salmon, while cooler ocean periods have coincided with relatively high salmon numbers.
Salmon productivity in the Pacific Northwest is clearly sensitive to climate-related changes in stream, estuary, and ocean conditions. In the past century, most Pacific Northwest salmon populations have fared best in periods having high precipitation, deep mountain snowpack, cool air and water temperatures, cool coastal ocean temperatures, and abundant north-to-south "upwelling" winds in spring and summer.
Rising stream temperatures will likely reduce the quality and extent of freshwater salmon habitat. The duration of periods that cause thermal stress and migration barriers to salmon is projected to at least double and perhaps quadruple by the 2080s for most analyzed streams and lakes. The greatest increases in thermal stress (including diseases and parasites which thrive in warmer waters) would occur in the Interior Columbia River Basin and the Lake Washington Ship Canal. The combined effects of warming stream temperatures and altered stream flows will very likely reduce the reproductive success of many salmon populations in Washington watersheds, but impacts will vary according to different life-history types and watershed-types. As more winter precipitation falls as rain rather than snow, higher winter stream flows scour streambeds, damaging spawning nests and washing away incubating eggs for Pacific Northwest salmon. Earlier peak stream flows flush young salmon from rivers to estuaries before they are physically mature enough for transition, increasing a variety of stressors including the risk of being eaten by predators.

Studies suggest that one third of the current habitat for either the endangered or threatened Northwest salmon species will no longer be suitable for them by the end of this century as key temperature thresholds are exceeded.
