The Urban heat island effect is not related to GW. See Real Climate:

Remember that the areas that are warming the most, as predicted by GW theory, are the poles. Temperatures up 3 to 5 degrees.

My brother lives in Anchorage, AK where the summer temperatures are much higher than even 20 years ago. And you can watch the snow pack dissapear from the Chugach Mountains.

Just to clarify further here, Global "Warming" does not mean it is getting hotter in your neighborhood.

The Global "Warming" phraseology is an unfortunate one that stuck before people realized it may send "wrong messages".

The increased trapping of solar energies by CO2 and other GHG's leads to Climate Change. Part of that Climate Change is the melting of the ice caps. Part of that Climate Change is the shift of annual rain patterns.

When rain fails to come to the MidWestern states, we have a dust bowl.

Yes it does make us pause and re-think the wisdom of the crowds regarding the biofuel strategy.
