Maybe it’s because I live in Canada but it’s really hard to get excited about a 4 degree warming trend over the next 100 years. First of all, humans like warmer temperatures so it’s hard to see how a warmer climate would cause us too many problems.
Studies have clearly shown that cold weather is much more dangerous to humans than warm weather. Also, the Earth has been warmer than it is today at various times in the past 250,000 years and during those warmer periods humans did far better than during any ice age.
That’s why the solution to climate change can be summed up in one word:
Yes, humans are the masters of adaptation to the environment. We can live anywhere on the planet and in any weather. Here in Canada the climate changes every year. In the summer it’s regularly 30 degrees Celcius and in the winter it can easily drop to -20. That’s a 50 degree change in 6 months! And what do we do? We adapt. You think we can’t adapt to an extra 4 degrees over the next 100 years. You’re an idiot.
