Global warming? But it’s colder!

I have seen several videos of Paul Douglas who, not only speaks beautifully, but offers excellent and clear explanations about how the weather relates to climate and how climate is changing more quickly than ever before. I think I will post more of these as they become available. Enjoy.

How can we determine a link between local weather and climate change?

On a very cold day, one will probably hear someone commenting along the lines of, “So much for global warming.” On a very hot and humid day, you’ll hear few comments at all about global warming. In other words, weather than stands contrary to the notion of warming usually reinforces skepticism that the planet is getting warmer, whereas weather that stands supportive to the notion of warming reinforces what’s typical or normal. In other words, it’s easy to assume that claims about global warming are linked to the word ‘warming’ as presented by temperature in the weather we experience. Because we also experience weather that is colder than what we might be used to, we automatically tend to assume it justifies skepticism about these warming claims.

It doesn’t.

What links weather to climate is patterns.

If global warming is true, then we should see changes to these patterns… and we do. But how do we link these changing patterns to anthropogenic (human caused) global warming rather than natural changes?

This is the meat of climate science. What should we expect to see?

Well, the most convincing evidence to me would be if it could be clearly shown that the rate and frequency of changing weather patterns was accelerating when all other natural factors could be accounted for.

And this is exactly what we find. In fact, the projected rates of pattern changes to weather norms are actually too conservative; the conclusion revealed by nature seems to be that climate change due to anthropogenic global warming is happening faster than predicted and the frequency of hot AND cold, wet AND dry is also greater. To help explain how AGW causes more extreme local weather, Peter Sinclair offers this video:
