Telling the truth

Telling the truth means being ready to accept when you have been led astray, got things wrong and so have to modify your views. Five years since the launch of Extinction Rebellion, this world we live in is changing so dangerously fast that it demands we revisit our assumptions and learn some painful lessons. 


It is now clear that 2023 is very likely to average more than 1.5 °C above a 1850-1900 baseline. Whilst emissions are still rising world wide. It is only through commitment to the truth that we might help humanity and wider life around as we enter a disturbing new era.


We got something wrong. We were misled. So, we misled you too. Aerosol matters decisively to our global climate.

Side lined

There are other factors deserving of more serious attention such as forest cloud seeding and ocean health. Many factors were side lined by scientists who were narrowly focusing on CO2.

In addition, IPCC processes did not find an adequate way to address issues of extreme risk where data was deemed insufficient or where there was higher uncertainty *, such as aerosols, methane release from permafrost, and feedbacks from wildfires or droughts rendering sinks incapable of sustaining their role in the system.

This misled other scientists, academics and activists including us. Some of us have attempted over the years to responsibly communicate the extreme and cascading risks, and the severe consequences of not taking emergency action.


Despite founding the movement on the precautionary principle we found ourselves being ground down.

For years we were moderated, and moodsplained by experts from narrow disciplines who demanded we change our press releases, our lectures, and play down the reality and potential speed of catastrophic consequences.

As we pass into the horrors of a 1.5 °C plus world, at least 10 years earlier than the worst official expectations, we realise we should have made a firmer stand.

As we observe some top climatologists claiming we need to wait decades before accepting that the planet is 1.5 °C warmer, we also realise that silence about our disagreements is no longer an option for us, or the climate movement. Understanding how this repression happened is important.


We would welcome any career climatologists, academics and journalists who undermined our communications in public to make amends, especially as they have influenced attitudes amongst those who judge us.

But more importantly, for the sake of life on Earth we must tackle this emergency with our eyes wide open to everything that we need to do from this point forward.
