Man Made Global Warming

When it comes to man made global warming I am a skeptic.  In fact,when it comes to all claims by scientists I am a skeptic.  Why?  Because scientists are, most of the time, wrong.  For example, in the 1950s pediatricians and psychologists were saying kissing and holding babies was bad for them.  No one agrees with that now, but just 60 years ago it was a scientific "fact".  Many scientists today say life appeared spontaneously from non-living matter. They are completely convinced that this idea is true. However, no one has been able to produce life from non-living matter. Why is this important?  Because it shows that scientists are willing to ignore the rules of their profession in order to assert a conclusion they hope is true. And when it comes to weather, scientists are unable to predict the amount of cloud cover next week, or the number and severity of hurricanes.  Their predictions for the 2013 Atlantic hurricane season were laughably wrong.  So, when they predict droughts, and extinctions, and rising sea levels I am pretty skeptical.  Not totally skeptical, just 60% or so.  But when they go on to say people are responsible for global warming I am 99.99% sure they are just making stuff up.
