Global Warming

An Inconvenient Truth………..Convenient Misdirection

And Profitable

During Last 150 Years, Temperature Tracks CO2 …. On this scale, CO2 appears to lead Temperature ... There must be some relationship!!

CO2 Data from Ice Cores

CO2 Data from direct measurement(Maunlua, Hawaii)

A Similar Relationship exists over 450,000 years. It seams reasonable to conclude that CO2 build-up causes Global Warming!!

Peak 400 years ago ….

• Higher and steeper than last 150 years!!

• Clearly unrelated to CO2 levels which were constant.

Temperature Precedes CO2

BUT …….. Expand the “150 Year” chart to cover 1000 years Now the relationship is no longer clear……Temperature does not track CO2!!

Zero in the “450,000 Year” chart to 150,000 yearsNote that Temperature often Precedes CO2. Unlikely that CO2 is causing Temp Increase

Temperature Precedes CO2

Normal Temperature Variation over last 10,000 years. Average Temperature is highly variable. Highs and Lows are normal.

Present Upward Trend is NOT an Unusual nor Unexpected Event !!!

CO2 has minimal impact on “Global Warming” Effect.

Water Vapor has major impact.

• Considered by many to be a mitigator. (I.e. increase humidity increases cloud cover and reduces greenhouse effect

CO2 has relatively small impact

Many other factors are in play!!

Global WarmingThe Facts are………..

– It is clear that humans are responsible for an increase in CO2 levels. BUT there is no clear or demonstrable “cause and effect” link between CO2 level and global temperature.

– Global temperatures will fluctuate with or without us. Always have, always will.

– Any “Human” effect will be additive to an already established temperature increase. There is no clear evidence as to the magnitude of that increase, but it is definitely small.

– Environmental causes are big business…..with very large profits. Nobody pays for studies or donates to organizations that report the facts without some angle that the “sky is falling”. The real truth is boring!!
