The further back you go, the larger the range that that data covers. For example, if we go back 24 hours, we can find the minute by minute temperature, precipitation, pressure, dew point, etc etc. If we go back 100 years, we may find daily high/low temperatures, and precipitation. Go back 10,000 years and you have the deduced average rainfall/temp for a 1,000 year period. Go back 740k years, and you have an ice core sample that spans a 75k year period. We have NO idea if within that 75k year timeframe, there were 50 100-year spans that were identical to the past 100 years, or if there were 0. Or 75!

The point is that we just don't have the data.
