HOW!!!!!!
It is funny they never mention that the average temperature is still below the 12th cenrury, when the European building boom occured. They fail to mention that the temperature has been dropping for the last nine years. How is having fewer babies going to make the sun warmer or cooler? Are these people really that stupid or do they think that I am? The temperature of the Earth is directly related to sunspot activity as proven by long term observations over several centeries as oppesed to their 'evidence' of a few years.
