Global warming had become essentially a business in its own right. There are NGOs, there are organizations, there are whole divisions of universities… - Anthony Watts

I have to think that because NASA chose to co-author this paper [LaDochy et al., 2007] with researchers at California State University, that some of the statewide "global warming as man-made problem bias" crept into the thinking for the purpose of this paper, i.e. "we need another study to show that its getting hotter so action is justified".

Of course we all know that the human race has historically done better during warm periods. While we've seen a slight warming in the last century, we've also seen a worldwide improvement in the human condition. Warm – what's not to like?

The sun is still the number 1 factor in our energy balance. No matter how much people argue about CO2, they can't successfully explain the pre industrial revolution 900-1300AD Medieval Warming Period or the cold 1645-1715 AD Maunder Sunspot Minimum that coincided with European crop failure, famine and disease while linking it with our modern day issues with CO2 to climate change. Yet sunspots and solar cycles can and do explain both.
