More than 10,000 blogs around the world are writing something about climate change on October 15 to mark “Blog Action Day.”

If you’re concerned about global warming, you may already have made small changes to reduce your own “carbon footprint.” You can significantly lower your energy consumption (and save money) with simple steps like hanging your laundry to dry and turning the thermostat down a few degrees in cold weather.

I also encourage you to get involved with at least one non-profit organization that works to reduce global warming. Whether you become an active volunteer or send a small donation once a year, your support will make a difference.

Here are 15 Iowa non-profits that deserve broad-based support. Although not all of them mention climate change in their mission statements, they all promote activities, land uses and public policies that would reduce greenhouse gas emissions.

Center on Sustainable Communities

In this comment thread, please recommend other non-profit groups working to reduce climate change.

Food advice for the Iowa State Fair, which runs from August 13-23: The best deal on lemonade is at the honey producers’ booth in the ag building. The best ice cream is in the Bauder’s truck, not far from the ag building. Don’t miss popcorn with real butter.

If you’re looking for something useful to do in August, I’ve got lots of event details after the jump.

Please consider attending some town hall meetings with members of Congress. Don’t let right-wing astroturf mobs dominate all of this month’s town-hall meetings.

As always, post a comment or send an e-mail to desmoinesdem AT yahoo.com if you know of something I’ve left out. You can volunteer for Curt Hanson’s campaign in Iowa House district 90 any weekend this month. I noticed that Mariannette Miller-Meeks has been knocking on doors for the Republican candidate, Stephen Burgmeier.

Who else is looking forward to the Iowa State Fair, which runs from August 13-23?

Please submit a comment to preserve public input on CAFO permits by Thursday, August 6. The Sierra Club’s Iowa chapter has made it easy for people to send comments to the right DNR official as well as all the members of the Environmental Protection Commission.

UPDATE: Added some public events featuring Democratic members of Congress. Don’t let right-wing astroturf mobs dominate all of this month’s town-hall meetings.
