Yes, 12,000 years ago the Earth was still within the last glacial period - the poles were large and the Great Barrier Reef was on dry land. Then the warming began. Over the following 4-5 thousand years the temperature increased, the poles largely melted and the sea rose. The warming peaked around 8,000 years ago (Holocene Maximum). Temperatures have trended down since then. Currently the temperature is still rising from the last mini-ice age (Maunder minimum 1645–1715). However, based on the sunspot count, it looks like we are about to plunge into another mini-ice age (Maunder minimum). So, we can expect this cold period to be colder than the last one as temperatures trend down into the next glacial period (ice-age).

Aren't you alarmed that all these graphs show natural fluctuations in the climate taking place over periods of thousands of years, and yet scientists are telling us they are now observing measurable changes in the climate happening within the span of one human lifetime? That is way way too fast for most species of life to adapt.
