Good source of climate change data

Our current location in the Milankovitch cycle is 6,000 years into a cooling cycle that should last another 23,000 years. The models say that, anthropogenic forcing aside, the current interglacial period is going to last another 50,000 to 650,000 years.

Here’s an older peer reviewed source for the current cooling trend in the cycle.

Quote:Model predictions. Radiometric ages for six of the climatic events listed in Table 2 were used in tuning the model. Calculated ages for the six other events may therefore be considered as predictions to be checked against the results of independent research. In addition, the model contains a prediction for the course of future climate (Fig. 7). Specifically, we take the model output to indicate that orbital forcing will act over the next 23,000 years to continue the general cooling trend that began some 6000 years ago. This effect must be superimposed on variations that will occur at frequencies higher than one cycle per 19,000 years, and on anthropogenic effects such as a possible warming due to an increase in carbon dioxide levels. This conclusion is robust against substantial parametric adjustments (Figs. 4 and 5) and consistent with many (21, 59, 66) but not all (54, 67) earlier predictions.



Also a non peer reviewed explanation of Milankovitch cycles including a description of where in the cycle we are now available here.
