To those global warming / climate change deniers:
I bought the hybrid Prius to do my small part to provide more time for my progeny to invent fusion power to overcome the catastrophe that global warming / climate change will be.
Many, on the other hand, are descendant from a long line of morons that include the isolationists prior to World War II, people who see Jesus in the asshole of a dog, the investors in Bernie Madoff and owners of 6000 pound gas guzzling SUV?s.

Which is more likely?
A majority of scientists have collaborated and concocted this huge plot to defraud the world community by falsifying data and photos.

Oil, Natural Gas and Coal companies, who have enormous financial resources to influence media, politicians and scientists, are spewing false information to primarily preserve their own jobs and stock options.

Why do we believe someone with such a clear conflict of interest and then vote and behave just as they want us to?

If you dare, read this paper written by someone who has no axe to grind. http://jou…2.0.CO%3B2

Do not rely on Uncle Goober who remembers that it was cold last week.

If you have children and grandchildren, join the party just in case you?re wrong.

to srschwartz1:

Your Prius might have a (prematurely) sticky thermostat. It’s not expensive to replace.
On a car driven every day I change it every 4-5 years.

Have you checked your tire pressure lately?

As regards the global warming issue, the earth is estimated 4.5 billion years old. We’ve only been able to determine everage temperatures gong back about 400,000 years. And the attached is the curve.'

My 2009 Prius and 2011 Prius does the same thing in winter here in central Illinois. I go from 50 mpg in summer to 35-40 in winter.
