Every US president since Lyndon Johnson has known about the catastrophic effects of greenhouse gases and done nothing but make things worse.

Now for a reasonable chance of decent survival there are only 9 years left to stop all emissions from the whole global industrial economy.

1. For a 67 per cent chance of not exceeding catastrophic 1.5C of global warming, 'total CO2 emissions must not exceed 230 billion tonnes. This is about five years of current emissions, or reaching net-zero emissions by 2030.'

This stark reality should provoke massive emergency action, but relatively few people are aware because the media remain silent.

Time to tell everyone.

3. But this is not just an abrupt climate change crisis, this is a biodiversity crisis, too.

The current utterly destructive global economy must rapidly be transformed into something else entirely.

4. The answer is to end the economic growth which is destroying the ecosystems that we depend on for our survive.

Scientists have demonstrated this is entirely possible.

5. The 'apocalyptic change' memo 'isn't remarkable for its dire warning. It's noteworthy because it is dated almost 50 years ago: September 17, 1969.'

We need new laws to end habitat destruction, and stop carbon emissions and all pollution in the 2020s.
