There has been no warming for over 16 years and this is not disputed. The Arctic ice melts to some extent every summer, now it's frozen over, so it's not melting at this time. Ever heard of Prudhoe Bay? You don't have to have melting to drill for oil. Watch Ice Road Truckers. That's ocean they are driving on for much of the time.
Severe weather alerts in 2012 were way below average.
