Are Carbon Dioxide emissions threatening to change our Global Climate?
If you have not seen Journey to Planet Earth on PBS, it is a must. In it Lester Brown and many other prominent world scientist discuss the "tippiing point" in our worlds current atmosphere whereby the carbon dioxide levels will cause a radical change in global climates. Our earth did not sustain life until several large changes in carbon dioxide levels (caused by volcanic action) produced a mixture that would hold in heat. The plants help maintain that balance. Now, with our energy consumption causing rising carbon dioxide levels, while we decimate parts of the rain forest, is causing a huge imbalance. We litteraly could see drought and familne the likes of which has never been seen and can't possibly be managed.
The experts argue that we are already at that tipping point. World leaders, including President Obama here in the US, are discussing this. However they are calling for large reductions in Carbon Dioxide emissions within 20 years!!
Should we find a way, as citizens of this planet, to make them act more quickly?
