Independent, 10 November 2015 (phrase in bold omitted):
It is quite extraordinary how the BBC is choosing to spin the latest news on climate change (“Halfway to climate disaster”, 10 November). The BBC’s science correspondent informed viewers that we are half way to 2 degrees of warming, the temperature level that is widely regarded as “safe” .
No reputable scientist thinks 2 degrees C is safe. Warming of 1.5 will flood low-lying areas. Two degrees is the point at which climate change becomes irreversible.
The carbon budget to keep temperature increases below 2 degrees C will be exhausted by 2040 at current emission rates. After that climate change will fuel its own progress through positive feed-back systems, notably methane releases from permafrost and the Arctic sea-bed, so the process becomes irreversible and mankind will lose control of the process.
