I do believe in climate change, I just don't think that mankind is having any significant effect on it (I believe climate change is a natural occurrence, not man-made, as historical records of past ice-ages and warming cycles indicate). Unfortunately the man-made climate change theory has become a political issue where people are verbally attacked if they question climate change models.
One thing to remember is that CO2 is a very important component in the atmosphere, without it photosynthesis would not be able to convert CO2 to plant matter, and life as we know it would soon come to an end - https://en.wikipedia.org/wiki/Oxygen#Photosynthesis_and_respiration. In fact, in order to grow plants in greenhouses the concentration of CO2 is often increased 2 - 3 fold to increase the growth rate of plants - http://www.omafra.gov.on.ca/english/crops/facts/00-077.htm.
Although I believe that man-made climate change is a red herring, the end result should be a cleaner atmosphere which is certainly good for mankind.  |
Ugh, I'm not going to keep this going, so we have to agree to disagree here.
The type of natural climate change that you're discussing does happen, but it's my understanding that it happens over thousands of years, not mere decades unless there is an unusual occurrence (such as a meteor strike or perhaps some unnatural activity ??). Regardless, to deny that our activities do not affect the environment is merely wishful thinking IMHO. Over and above the ever-popular climate change, there's also polluted air, chemicals in our oceans and water supplies, etc. etc.
For that matter, where's all the lush greenery that should be proliferating due to all that excess CO2?

There are studies... everywhere. Research... everywhere. Many contradictory. Some honest. Some "sponsored"... you get the idea. The media fires them at the public all day every day until the average Joe doesn't know what's right or what's wrong, but it does give them the opportunity to cherry pick data to support whatever they want to believe. Then the internet becomes rife with 'debates' about it, and in the mean time yet another thread goes wildly off-topic...
