No it's not. The little ice-age is a well documented period of time of below average temperatures at the end/after the medival ages https://en.wikipedia.org/wiki/Little_Ice_Age https://en.wikipedia.org/wiki/Little_Ice_Age There's still a lot of speculation going on, what caused it, because the explanation for the "Big" ice ages (the periodic tilting of the Earth's axis reaching a position that gives to a colder climate) doesn't fit. So there are a lot of possible explanations. From archeological evidence we know that in the timeframe before the little ice-age begain large parts of the North American population fell victim to disease and/or famine, so one proposed model is, that the regrowth of forrests on (fertile) ground left unmanaged by the decreasing population sucked out a lot of CO2 from the atmosphere.
