Talking about anecdotal temperature data, which isn't climate, isn't helping the climate change movement.
To me, it's like saying that the temperature is below freezing today, so global warming isn't true.
On the other hand, we don't need any more evidence. There is plenty of evidence already. This won't persuade anybody, but maybe it will motivate somebody.
Why is a warmer Earth bad? I'd rather this new climate than the climate of the Little Ice Age. Humans tend to do better in warmer climates.
