for energy production could increase atmospheric carbon dioxide levels<br />

This part is adequate. to the extent that the resulting enhanced "greenhouse effect" would<br />

CC: Or. D. V. Hansen waste disposal in polar ice should consider that global circulation<br />

models which assume increased CO-2 levels indicate that the largest<br />

warming trends would be in Polar regions. An increase in annual<br />

mean temperatures by 12°C or more well before the end <strong>of</strong> the next<br />

century is possible, according to these models. A climate change <strong>of</strong><br />

such a large magnitude would likely cause significant changes in the<br />

depth <strong>of</strong> Polar ice and snow, especially in the Northern Hemisphere.<br />
