Page A6 of today's "climate change is really happening" Globe and Mail edition (Saturday Jan 27/07) contains a graph, sourced to "Globe and Mail research", depicting the temperature change cycle of the last 400,000 years. I have no idea how it was sourced. Maybe the cave men were writing on walls somewhere.
In any event, it demonstrates a cycle of roughly 120,000 years where temperatures rise, peak, and then fall. The graph ends at "today", with temperatures at a peak. The previous peaks were at roughly 375,000 yrs ago, 240,000 yrs ago, 130,000yrs ago. Each trough (cooler) point on the graph is at roughly the same value and of roughly the same duration.
Each of those peak temperature points are higher than the peak temperatures the graph shows us at today.
There were no cars or factories until 100ish years ago. So what the hell caused the cyclical temperature variations that are more extreme than what we're seeing today? And why do we suddenly think we're to blame?
And it had better be more convincing than this jibberish:
"Paris is forecast to be unseasonably warm next Friday. The current long-term prediction is 8 degrees, significantly above the historic high for early February of closer to 5." Oh boy, a possible record-setting high or low temperature! I've never lived through a record high (or low) temperature on one given day myself...
Don't respond to this post unless/until you have seen the graph. Unfortunately it does not seem to be available online.
