Let me explain to you why this assertion is just stupid... global warming proponents who are scientists do not say that global warming will result in warmer temperatures for the whole period... as a matter of fact they are saying that once the ocean currents are interrupted by the lack of polar ice that we will actually enter another ice age... this is the biggest concern... warming itself is not a threat... changing the ocean currents is.
