I previously posted about the scariest global warming graph I've ever seen.  This was a graph from an MIT Study that shows there is a 50% chance the world will warm by 5ºC by 2100 under business-as-usual.  I might as well said that an asteroid is heading for earth!  Yet, we humans do not react to threats that are not visible, immediate, caused by an enemy, or that do not have historical precedent or simple, personal consequences -- even if it's the biggest threat mankind has ever faced!

To help put the threat in terms that people can relate to, I offer the following illustration:


This is a non-scientific illustration of possible global average temperature increases compared to crashing your car in a brick wall at various speeds.  And note that you have no air bags, no seat belts, and all your children and future grandchildren are in the back seat.

You can view a recent talk I gave on climate change at   The talk is 52 minutes long plus about 15 minutes of Q&A (sorry for the limited AV set up in the hall).  The MIT Study is discussed in Chapter 4 and the Car Crash is Chapter 5 (you can skip to chapters after the ad plays).  You can get more information and copies of the slides at my website,

I've come to the conclusion that climate change is the biggest psychology and marketing communications problem we have ever faced.  We must quickly get people (especially our elected leaders) to understand the clear and present danger that climate change poses.  Suggestions on how to achieve this will be appreciated!

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
