Canyonman00 what there saying there saying they cant make a point if its non cyclical or if its human causing the warming. But there is empirical evidence the earth is warming. But the question is if it is cyclical. meaning if we are entering a warming stage of earth. Or if its man made. You cant dispute the evidence that we are entering a warmer climate.
Quote from canyonman00:
The very study you offer states the following:
----------------------
The scarcity of precisely dated proxy evidence for temperatures before 1600, especially in the Southern Hemisphere, is the main reason there is less confidence in global reconstructions dating back further than that. Other factors that limit confidence include the short length of the instrumental record, which is used to calibrate and validate reconstructions, and the possibility that the relationship between proxy data and local surface temperatures may have varied over time. It also is difficult to estimate a mean global temperature using data from a limited number of sites.
----------------------
That means they have no proof beyond 1600 by there own admission. So empirical proof that the warmth is not beneficial to the actual planet does not exist huh?![]()
