Common sense says that what should be in the air is what naturally occurs there. This is the same sense that tells us that the only we should bring in to our lungs is just the air we breathe. I’m sure burning fuels is not good for the air but going back to the time of burning logs for heat wasn’t good as well. Furthermore making such bold statements about our “role” in this world appears a bit hubris especially when we consider the time frame that we are basing this on.
Yes, the climate is changing and I’m sure we are having some impact on it but we can’t ignore the thousands of other aspects that occurring in our atmosphere that have such impact on it such as Volcano eruptions, cloud cover, meteorites etc. Scientist must analysis all those factors and look at other facts that are much more difficult to account for like past centuries where record keeping was less accurate as it is today. Furthermore, biases to fit in with what others are saying, receiving governmental grants to say what your supposed to say and being completely shunned by those in powerful circuits must also be assessed as well. Debate has been shunned as our top leaders deny there is room for any discussion and that’s not healthy for those who might disagree and for those who could see a different solution. We also can’t ignore the financial, power and political gains that others are achieving by creating a climate hysteria.
To conclude the only logical answer one can observe in this current debate is “I don’t know whether we humans are having an extreme detrimental effect on the environment”. Yet I’ll do my best to make an impact for the positive and maybe I’ll plant an extra tree or two for that is one time that will lower my CO2 and they looks good as well.
