There have been vast periods of time in Earth's history when the polar ice caps did not exist at all! The planet was much warmer than it is today. Life flourished.
For several instances, the last being about 12,000 years ago, severe and sudden global cooling caused the icecaps to reform and glaciers extend all the way down the Indiana and Ohio in the US, covering half of Europe. The planet was much colder than it is today. Life flourished.
Today's climate drift, if real (our database is pitifully short as human records date only back to the middle to late 19th century in metropolitan areas, later in others), is well within the normal parameters of Earth's temperature range and no cause for alarm. For every catastrophic effect receiving gleeful publicity and hand wringing, there will be one, perhaps more, beneficial effects which have no highly motivated press agents right now.
"Global warming," "climate change," whatever you want to call it is a political, not a scientific issue. Science is merely curious. That is good. Politicians will never let a crisis, real or imagined, go to waste in pursuit of their agendas.
It is entirely possible to assemble a library of books agreeing with your preconceived attitude toward the goodness of mankind, the dark possibilites for the future and the inherent evil of non-socialist thought. However, assembling such a library is no substitute for valid evaluation.
I could easily assemble a library of books seeking to prove NASA never reached the moon.
