Effects of climate change
So, just what might happen if nobody does anything to change and the planet continues to heat up? Scientific projections include:
- Sea levels could eventually rise 70 metres (as the paleoclimatic record shows occurred in the Oligocene period 30 million years ago).
- Oceans will acidify and a warm layer on the water’s surface will destroy the base of the ocean’s food chain.
- Most of the tropical and much of the sub-tropical land area will turn to desert.
- Mass extinctions with loss of about 50% of all species.
“If you have got a population of nine billion by 2050 and you hit 4°C, 5°C or 6°C [higher temperatures], you might have half a billion people surviving.” Professor Kevin Anderson, director Tyndall Centre for Climate Change, UK.
