Global Warming? It's cold

Once again in Maryland it is very cold for this time of the year. I want advocates of Global Warming Theories to first of all acknowledge that it's cold! and then explain why we have had such cool temperatures in the midst of a man-made crisis.

I am humble enough not to pretend to know what is going on with an Earth that is so vast. But others are insistent that they do know. Scientists, politicians, and people of many varied professions all resent any questioning of man-made global warming.

Please explain why it has been so cold for so much of the time over the past two years.
If a heat wave returns, don't return with your theories unless you can explain the coolness.
