I trust what I see with my own eyes. Satellite views of the North Pole and the obviously shrinking ice sheet. Polar bears drifting around on ice cakes miles from land.
An ice floe the size of Rhode Island that broke off from Antarctica.
In my own yard, Cardinals, the state bird of north Carolina, never seen in Maine until recently. Possums, unheard of in Maine! Buzzards, another southern bird. The last 10 years are the hottest on record according to NOAA, National Oceanic atmospheric administration, not some chicken little scare monger.
