it seems to be assumed by the experts that any natural climate change occurs at a constant rate and therefore any change in the rate of change must be due to other factors. Given that long term natural climate change is a function of our orbital cycles, just as the rate of change in our daylight hours is greatest at the equinox and slowest at the solstice, so it will be with other cyclic changes. Just to get things into perspective, at the solstice the hours of daylight change about 1 minute over 7 days, however at the equinox the rate of change is about 25 times that, or 25 minutes over 7 days.
