Global Cooling and a Climate Denialist Who Forgot Who Once Solved the Acid Rain Problem

The following is from an email to a friend who denies global warming as having a man made cause. He dropped of a 1975 Newsweek article on Global Cooling:

Read the article. Interesting. Thanks. Looked it up some and found this on Wikipedia, that great source of information for Rand Paul speeches: 

 Global cooling was a conjecture during the 1970s of imminent cooling of the Earth‘s surface and atmosphere culminating in a period of extensive glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the full scope of the scientific climate literature, i.e., a larger and faster-growing body of literature projecting future warming due to greenhouse gas emissions. The current scientific opinion on climate change is that the Earth has not durably cooled, but undergoneglobal warming throughout the 20th century.[1]

 Also, found the graph of global warming and cooling cycles for the past 425,000 years covering 5 glacial periods. The data stops at 1990 on this chart:

And between 1990 and the present the rate of temperature rise has exceeded the highest peeks from the past 425,000 years to about +4 degrees celcius. You will also notice that we really should be entering into a global cooling period based on the pattern you see above. Here is the current trend:

So to say the temps have been rising since the last ice age is as true as it is irrelavant. We should be heading into the next ice age, not shooting up to tempretures that haven’t been seen for a million years.

I also reminded my friend that Acid Rain was once a much bigger problem. Everyone accepted back then that it was a man made problem caused by sulfer released from coal and oil fired electric plants. A sequestration plan and cap and trade system was passed, which was a Republican plan opposed by many Democrats. But it worked and acid rain is not the critical problem it was back then. So here we are facing an even bigger man made problem and the opposition is from the party that solved acid rain with a cap and trade method that worked. go figure.
