A few years ago, prior to Australia’s ‘Black Summer’, I began capturing extreme events as I became aware of them escalating to a frequency of becoming annual events - some type of disaster of unprecedented scale occurring somewhere where such an event was previously unheard of. 🧵

It's about time global northern governments faced up to this oncoming problem.
Presently they are putting up more barriers to immigrants as right wing ideology prevails.
They must realize that ignoring the issue will cause a total catastrophe for all.

Hey Murdoch fake-news media! The study you report on here
1. Predicts nothing but is about the past.
2. Is not about Gulf Stream but #AMOC.
3. An AMOC collapse wouldn’t cause an Ice Age.
Incompetence or intent to confuse?
The study by Ren et al shows AMOC has weakened: www.nature.com/articles/s43...

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead.

The fact that the Netherlands (18 million inhabitants, ~at 52°N) has more solar installed than all of Africa (1,561 million inhabitants, entirely in the sunbelt) is a gross failure of humanity.

Today is the 60th(!) anniversary of the first public report on the dangers of fossil fuel pollution.
What happened? A whole lot of fossil fuel bullsh*t and corruption in service of a whole lot of nothing.
All while pollution and warming escalated far beyond what scientist predicted in 1965.

This Whole Thing Really Snuck Up On Us
Looking back, and ahead, on the anniversary of a White House warning.
