Arctic Scientists See Faster Melting, Higher Floodwaters for Philadelphia Area

Jan 29th

Philadelphia, PA (Vocus) October 21, 2009 -–

Two of the world’s leading experts on the ice melting in the Arctic came to town today to tell what they’ve seen, and to demonstrate the implications for the Philadelphia/Camden region. They released the most detailed maps and video animations yet of exactly what could go under water this century in this area.

According to the scientists, the old estimates for rising seas due to global warming were overly optimistic. Fresh data from the poles now indicates between three and four feet or more of rise by the year 2100 or sooner, which will More >

Tampa, FL (Vocus) October 23, 2009

Tampa-St. Petersburg, FL (Vocus) October 22, 2009 — One of the world’s leading experts on the ice melting in the Arctic came to the Tampa Bay area today to tell what he’s seen, and to demonstrate the implications for the region. He brought with him the most detailed maps and video animations yet of exactly what could go underwater this century in this area.

According to Dr. Gordon Hamilton, a research professor at The University of Maine, the old estimates for rising seas due to global warming were overly optimistic. Fresh data from the poles More >

Question by Ianava: Where does Energy disappear to when a solid contracts when melting? I have a question here that tells me the change in internal energy (U) is positive, Heat supplied (Q) and work done on mass (W) are all positive in the melting of a solid that contracts while melting under constant pressure. I am asked to explain why but i do not know why.

I thought that since Q is positive, it is used to weaken the intermolecular bonds (molecular Kinetic energy does not change as temp is constant while melting). Since intermolecular forces are weaken, particles More >
