Global Warming

How do the Global Warming Alarmists explain these recent events?

1. 6-12 inches of snow predicted for Minnesota on April 25, 2008
2. the first recorded snowfall this past year in Bagdad, Iraq
3. China, Canada and England have experienced unusual cold and snow this winter
4. record snowfall in Anchorage, Alaska April 25, 2008

There are many more examples, but the Alarmists can start with this short list.
