Humans have tipped the Earth off its axis - Dr Karl Kruszelnicki

Dr Karl Kruszelnicki - he
discusses the changes we
are making to the Earth.

We are only a little way into the 21st century, and the signs of global warming are clear. Even so, the latest finding really surprised me. By burning huge quantities of fossil fuels, we humans have actually tipped the Earth off its axis by a tiny amount.

Each year since 2005, our global warming activities have shifted the spin axis from its previous path (by centimetres).

We humans now shift as much dirt as all the rivers on Earth added together. It comes to about 20 billion tonnes a year – mostly coal, followed by iron ore. This is a huge amount – but by using carbon dioxide, we moved an amount of water 30 times greater. We melted ice on land to water, which then relocated all over the entire planet.
