ORIGINAL: KYsissy 30-40 years ago the settled science was the coming Ice age. The problem is that climate change is no longer a scientific issue, it has become a political issue. Is the climate changing? Of course it is! Always has. Always will. If it never changed Chicago would be under a mile of ice. The are eons of temperature fluctuations, some are very dramatic swings. You can look at any set of data and pick a portion that supports your position. Out of the millions of years worth of data, we have only captured this infintesimal, teeny, tiny, slice of it. And much of that data is suspect. Many "official" temperatures are recorded in urban heat islands. And this is why people like you need to take a class on climate. 1) Proxies, we have many examples of indirect evidence pointing to the conditions of past climate, so by combining proxy data worldwide, we have a good example of what climate was like in the past. 2) Temperature fluctuations and cycles do happen in climate all the time, except for the fact that the three main climatic cycles that drive climate change on this planet happen over too large of a time scale for current climate change to be attributed to them. 3) Fluctuations in climate are usually in response to something. Changes in insolation, aerosols in the atmosphere, a dying off of vegetation which results in a change in albedo, increased weathering on newly exposed rock, changes in atmospheric chemistry by biological means, etc. There is always a cause and effect when it comes to climate. When you spew a heat trapping gas into the atmosphere in the millions of tons that we do yearly, you're going to see a gradual increase in global temperatures over time. Cause, please meet effect. This is not political, this is fact, if you want to understand the facts then please ask and I'll give you some info to tide you over.
