James O’Brien, an emeritus professor at Florida State University who studies climate
variability and the oceans, said that global climate change is very important for the
country and that Americans need to make sure they have the right answers for policy
decisions. But he said he worries that scientists and policymakers are rushing to make
changes based on bad science.
“Global climate change is occurring in many places in the world,” O’Brien said. “But
everything that’s attributed to global warming, almost none of it is global warming.”
He took issue with the AP article’s assertion that melting Arctic ice will cause global
sea levels to rise.
“When the Arctic Ocean ice melts, it never raises sea level because floating ice is
floating ice, because it’s displacing water,” O’Brien said. “When the ice melts, sea level
actually goes down. I call it a fourth grade science experiment. Take a glass, put some
ice in it. Put water in it. Mark level where water is. Let it [melt]. After the ice melts,
the sea level didn’t go up in your glass of water. It’s called the Archimedes Principle.”
