What evidence from glaciers and sea-level measurements corroborates global warming?
What will be an ideal response?
Glacial-ice melting should cause glaciers to retreat when temperatures rise. The average length of 169 glaciers from around the world has been decreasing since about 1850, and so has global temperature. The most rapid decreases in glacier length were between about 1925 and 1950 and since 1980, which are also the time of greater warming.
Sea level should rise when temperature rises because (a) warming melts glaciers to add water to the oceans, and (b) water expands as it warms up. Sea level has been rising for more than a century, as has global temperature, and the rate of rise has increased since 1970, which is also a period of faster temperature rise.
