“Cities that currently experience heat waves are expected to be further challenged by an increased number, intensity and duration of heat waves during the course of the century, with potential for adverse health impacts..”

Slide from California Air Resources Board presentation January 22, 2007
AB 32—California Global Warming Solutions Act (2006)
• Economy-wide GHG emission reduction to 1990 levels by 2020 (about a 30%)
• California Air Resources Board—lead agency. California EPA and Climate Action Team will oversee multi-agency coordination.
• Legislature may also play role through budget process or through legislation to require certain regulations

Communicating With the Media
• Write a letter-to-the-editor (respond to stories out today)
• Monitor local news for climate contrarians and respond with letter-to-the-editor
• Make a call today to your newspaper’s environmental reporter and offer to help with background information or make a statement.
•Meet with an editorial board of your local paper
Remember your audience
Before talking to a reporter, develop some main messages and talking points
Keep it simple
Frame it in human terms
Tips for Interviews
Materials & Resources on UCS Website:
• IPCC Process Backgrounder, IPCC Flyer
• UCS brochure on key findings of WGI. WGII brochure available for download in a week
• UCS ppt presentation on key findings of WGI. WGII ppt slides available for download in about a week.
• SSI members will get an email notifying you when the WGII materials are available

WATER
•Many rivers that derive water at their source from melting glaciers or snow will have earlier peak runoff in Spring and an overall increase in run-off, at least in the short term.**
•The temporary increase in water flows will not always be welcome. For example, glacier melt in the Himalayas will increase flooding and rock avalanche risks, while flash flood risks will increase in inland areas in Europe.***
Temperatures are Relative to Today•Global average temperature increase in these slides is expressed as temperature rise above today.
•Add 0.8 degrees Celsius to convert these to temperature rise above pre-industrial (about 1750) levels.
•The numbers and figures in the summary for policymakers uses temperature rise above 1990 levels which is 0.6 degrees Celsius above pre-industrial levels.
Thank you!
