Until we see larger trees growing again on Greenland, the climate has not yet returned to it's "normal" state before the Little Ice Age set in around 1300 AD.
It may be of interest to some that the IPCC Climate Change report in 2001 dismissed the Medieval Warm Period from 900 AD to 1300 AD and the Little Ice Age from 1300 AD to ~1915 AD as not existing leading to the infamous quote from Al Gore: “
Our civilization has never experienced any environmental shift remotely similar to this. Today's climate pattern has existed throughout the entire history of human civilization.”
Neither side of the climate change discussion has even close to clean hands but the climate change is driven by humans side has definitely gone a lot further in their abuse of the scientific method -- gee, you mean modifying the mean temperatures recorded world wide in the 1930s and 1940s isn't a valid technique? Dropping 75% of the temperature recording stations and retaining only those that showed temperature increases? And don't even get into the code used to generate the infamous "hockey stick" since the Climategate hack showed that no matter what the input data, the output did not change.
Also note that contrary to what appears to be the common belief, carbon dioxide is not the only greenhouse gas nor is it even the most effective one. Dihydrogen oxide (AKA water vapor) is number one on that list along with methane and some less common gases such as nitrous oxide, ozone, sulfur hexaflouride, chlorofluorocarbons and hydrofluorocarbons.
