Milankovitch cycles are long-term variations in Earth’s orbit and tilt that have a profound impact on our planet’s climate over tens of thousands to hundreds of thousands of years. These ...

One of the earliest examples that proposed a connection between climate-driven environmental change and hominin evolution was the "Savanna Hypothesis", which posited that the human lineage ...

One of the most important systems explaining these patterns is the Milankovitch cycles, a theory that connects variations in Earth’s orbit with long-term climate change.

The Milankovitch Cycles consider the wobble of Earth's axis and change in orbit shape in relation to climate change both past and present.

These cycles are quite separate from human-induced climate change, which is well documented, incontrovertible and is largely overriding Earth's natural climate cycles.

While the exchanges between Rolf Westgard and Professor John Abraham are interesting, they do not deal with the really long-term elements of climate change. I invite them, through the opinion page ...
