| Parrot, I don't think you got my point about graphs? You can use any time span you wnat to make a point. If you include a span of a decade you may show a temperature rise that would not average as dramtically as if you showed a span of 50 years?
Your response included temps from the 1970s which were in a decidedly cooler era(the middle of the century). What comes out is that such stuff is relative to what the depicter wants us to see. Example the dramatic "hockey stick" graph which excluded a period of warming a thousand years back. Including that period would have made the graph less dramatic.
The climate records which we have indicate that there have been periods(some short, some long) of climate change over the eons. CO2 was not an influencer for warming and followed rather than preceded global temperature changes. The vast oceans of the earth emit and absorb CO2 as they are warmed by the fluctuating solar heat.CO2 is about 1% of the earths atmospheric content and humans contribute some fraction of that? Its a puzzle that we haven't solved.
Thus we play the fools with the time, and the spirits of the wise sit in the clouds and mock us. |
