When Gore flies somewhere to deliver his message his trip will hopefully reduce
carbon emissions by a great deal compared with the emissions he contributed by
flying. Compare that to a business exec that is flying somewhere and the outcome is
making some widget that will use even more carbon emissions.

There are separate questions/facts to consider.
1. Has CO2 increased to unprecedented levels?
CO2 absorbs and holds IR extremely well. As CO2 levels increase, temperature
increases. As CO2 levels decrease, temperature decreases.
CO2 levels have never been higher in 650,000 years than they are now.

2. What is causing the increased CO2 levels?
Natural cycles, volcanoes etc, but no other natural cycle in 650K years has been this
high. What is different in this cycle is humans burning fossil fuels.

Consider the cycle of ozone depletion. The "hole" was huge and getting bigger every
year. Humans banned CFCs and the hole has stopped expanding and appears to be
closing.

Carefully examine the bias of people (spokespeople, scientists, etc) who deny the
human factor and there will be some link to carbon emissions for money.
