Agree with prolag, I don't deny climate change but I disagree with all the lemmings who are spoonfed this idea that climate change is caused by human activity. You're being manipulated, and fleeced by "carbon taxes", as if a tax ever solved anything. The earth's climate is a dynamic system undergoing constant shifts which =change. It is plausible that we are contributing in some way with our polluting, but as a matter of fact the earth has been going through a warming phase since the "little ice age" which occurred from about the year 1400 to 1800.
