NO discussion of GLOWBULL warming should take place without examing the following graph of temperature measurements since

Even the most ignorant observer will notice that temperatures change through the years BUT it was warmer in the 1930's than anything we've seen recently.

BUT if you are foolish enough to look at the ADJUSTED TEMPERATURES, it becomes clear that the data is being corrected LOWER before AL GORE and HIGHER after AL GORE started his GLOWBULL WARMING scam.

SUMMARY: The ADJUSTED temperatures indicate a warming planet but the raw measured temperatures do NOT. I suspect the "scientists" are adjusting based on rising CO2 levels, not on anything measured relating to temperatures of the Earth.

As I see it, the figure you presented is, from 1890 to 1990, an example of anthropogenic global cooling - at least in the sense that the modification of the data was certainly man-made.
