No one denies climate change. Sensible people just deny that it is caused by humans and that a 1 degree change in temperature will doom mankind or even have an impact. We do believe that reducing carbon emissions at the expense of having electricity and cars available on demand WILL certainly harm mankind.
At both poles typically the average annual temperature is -49 F. Worst case scenario by the models is a global increase in about 7 degrees.
At -42 F not much melting going to happen.
