The shifting climate truth or lie.

Currently more and more, increases the number of scientists who declare for current data, climate change as we understand it, may be just the own climate cycles. Studies carried out by researchers focus in many cases in the last, to find the current keys, which is given for calling the Paleoclimatology, which is very clear that there are so many factors involved in the process of the climate, which is not possible to determine the consequences and causes. On the other hand, CO2 is known that it has an effect on the temperature of the atmosphere, increasing this, when it increases CO2, these data are very proven, and that according to the last IPCC report, environment places it at 3 degrees Celsius, although there are authoritative voices in the matter that warn that in the past 17 years, they say that instead of 3 degrees CelsiusWe would be talking about 2 degrees, even an independent researcher as Nic Lewis, says that the value most likely be 1.6 degrees Celsius, having to rectify IPCC. Anyway there is no firm agreement on this topic, and not all researchers have the same opinion on climate change.
