From the sssf. Another instance of scientists speaking out. Even if you have heard parts of this before, it is worth a second read as nothing can be made clearer.
>>Early reports are predicting that a doubling of CO2 may in fact produce between 2.8 and 5.8°C of warming. Incredibly, at least eight of the latest models produced by leading research centres in the United States, the United Kingdom, Canada and France are showing climate sensitivity of 5°C or warmer.
To restrict warming to 2°C above pre-industrial levels, the world needs to triple its current emission reduction pledges. If that’s not bad enough, to restrict global warming to 1.5°C, global ambition needs to increase fivefold.
Examining the Earth’s climatic past tells us that even between 1.5 and 2°C of warming sees the world reconfigure in ways that people don’t yet appreciate. All bets are off between 3 and 4°C, where we are currently headed. Parts of Australia will become uninhabitable, as other areas of our country become increasingly ravaged by extreme weather events.
There is a very rational reason why Australian schoolkids are now taking to the streets – the immensity of what is at stake is truly staggering.<<
