You need to separate the Climate Change issue from the Man-made Global Warming issue. There is evidence that we were going through climate change, but their is nothing but speculation related to Man-made Global warming claims.
Ask yourself why the sea levels are not rising when the ice caps are supposedly melting rapidly. The only recorded rising sea levels have been proven to be sinking land masses, i.e., Venice, Italy and some South Pacific islands.
Consider the fact the the sun has been putting out more radiation than we have ever recorded before.

Fluctuating solar activity explains whey there have been two period in the last 3000 years that were much warmer than today, The Roman Warming (200 BC to 600 AD) and the Medieval Warming (900 AD to 1300 AD). There was also a span of 500 years that was much colder than today called the Little Ice Age (1300 to 1850). We have been recovering from that since then. There is plenty of information on the web about all three of these climate change cycles, but you will rarely hear it mentioned in the mainstream press.
Consider that other planets in the solar system are also heating up. I wonder how we can be blamed for that. There is plenty of information, but it is being suppressed by the mainstream media.

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
Consider that there are hundreds of computer models predicting global warming trends, but no two models match, which tells me that the models are all flawed. If the models were not flawed, dozens or perhaps all of the models would match.
Consider that more than 700 international scientists have rejected and challenged the claims made by Al Gore and the United Nations. They even filed a report with the US Senate that you probably never heard about in the news.

What this comes down to is a huge environmentalist conspiracy to use taxpayer money to fund their cause. Billions of dollars are being poured into research that was not funded in the past. Follow the money and everything makes more sense.
The simple answer is that climate change is cyclical and cannot be prevented. The lie, due to lack of factual evidence, is the Man-made Global Warming claim.
