The melting of Greenland and Antarctica is changing the Earth's rotation

30. Without GPS, how would you notice a 1.6km difference in where the pole is?

On a 40,000km circumference of the Earth, that's 0.00004 of the circumference - or 0.0144 degrees. Do you really think that difference in the height of the Sun above the horizon would make a noticeable difference to us? That being 1.6km closer, or further away, from a pole, is something that would be noticeable over 10,000 years, compared to the climate changes we're undergoing because of temperature or rainfall?

The British comma butterfly has moved 137 miles northward in the past two decades, while geometrid moths on Mount Kinabalu in Borneo have shifted uphill by 59 metres in 42 years. The quiver tree of southern Africa is increasing as it moves towards the south pole, but dying of heat and water stress in its shrinking northern range. Dartford warblers have been steadily moving northwards in the UK while declining on the southern edge of their range in Spain.

In the seas, rising numbers of warm-water crustaceans have been found around Norway's polar islands, while the snow crab has extended its range northwards by up to 311 miles. The IPCC report warns that many species will be unable to move fast enough to track suitable climates, with plants, amphibians and small mammals in flat landscapes or that remain close to their breeding site particularly vulnerable.
