Human-induced global warming using today's technology can be thought of as a geologically
temporary phenomenon. Why is this? What will be an ideal response?

Question 2

How does the principle of isostatic rebound apply to Hudson Bay? What will be an ideal response?

Answer to Question 1

Today's technology is based upon the use of fossil fuels, a nonrenewable resource. Once it is gone, the
human component of global warming will also be gone. Ultimately, in the absence of this influence,
the Earth will return to its natural climatic pattern

Answer to Question 2

Hudson Bay was the center of the North American ice sheet during past glacial episodes. This was the
area where ice was thickest and hence heaviest. The weight of that ice depressed the lithosphere
beneath it to below sea level. The evidence for this is the existence of Hudson Bay itself, which lies
well within the interior of the continent. Melting of the ice was sudden, in the sense that it happened
faster than the underlying lithosphere could elastically adjust. This adjustment, or rebound, is still
happening via uplift at the rate of about a meter per century. Portions of Hudson Bay have uplifted by
over 250 meters.
