Let's examine this.
theguardian.com/environment/20…
Yet Boris Johnson admits "“There is no chance of us getting an agreement next week to limit climate change to 1.5 degrees."

One of the main criticisms of all these Net Zero by 2050 plans is none contained plans to reduce emissions now.
independent.co.uk/news/uk/politi…
However, to keep below the Paris 1.5C target, there needs to be drastic reductions to emissions before 2030.
theguardian.com/science/2021/a…
There is a massive disconnect between what politicians are saying and what they are promising to do. They keep mentioning 1.5C, but none have any credible plans to keep below 1.5C. In fact their policy is likely to lead to 2.7C of warming.
sciencenews.org/article/climat…
We have very little time to keep warming below 1.5C of warming. On the current carbon budget for reaching this, on current emissions we have less than 7 years left of that budget. Yet UN calculations estimate emissions will rise by 16% by 2030.

The problem is not the vagueness of the plan, but it's incoherence. 🧵below.

"And he agreed a pledge for all the biggest economies to achieve net zero emissions was “vague”, after the G20 failed to set a target date of 2050."
independent.co.uk/climate-change…
There are actually 3 clear and separate components, necessary to address the climate crisis, and achieving Net Zero in the immediate future is only one of them. Focusing on only 1 component is leading to serious incoherence as very few people are looking at the whole big picture.
Even if these plans to reach actual Net Zero by 2050 were realistic and likely to achieve this goal, and all the evidence says the proposals are a long way of reaching actual net zero, a massive elephant in the room is being ignored.

1) I want to create a mini-thread here, to go through this revealing insight into Boris Johnson's thinking on the climate crisis. I think this very important, because we rarely get this type of insight. 🧵
independent.co.uk/climate-change…
2) The first think that stands out, is his warning of possible civilization collapse. Not least of all because I've been consistently saying this myself and actually using the collapse of the Roman Civilization in Britain as an example.
3) First I want to deal with what I consider the most important revelation.

"Admitting his own “road to Damascus” conversion - after a journalism career in which he scoffed at climate change - Mr Johnson said the key moment had only come after he became prime minister."

Further to my point about this, and it is really crucial for understanding the climate and ecological emergency we are in, and the failure of our system to change direction, is what Kuhn says about paradigm shifts and the structure of scientific revolutions.🧵
Thomas Kuhn says science textbooks give the false impression that science is a slow accumulation of knowledge and so the new big picture science portrays, the new paradigm is consistent with past understandings of science. Kuhn says this is not the case.
Kuhn says each time there is a major paradigm shift, that the new paradigm is often incommensurate with previous scientific views of the world. That it creates an entirely different view of the world we live in.

Nothing better illustrates the fallacious government thinking over the climate and ecological crisis. How not only Boris Johnson, but other world leaders, treat it like a PR crisis, and not the actual crisis it is.
theguardian.com/uk-news/2021/o…
Only yesterday the latest UN report warned us that on current government plans around the world, we are on course for 2.7C of warming, nearly twice the below 1.5C of warming target of the Paris agreement.
theguardian.com/environment/20…
It is very difficult to know what is going on here, other than our political and business leaders seem to be detached from reality and appear to believe that this crisis can be addressed with propaganda and spin.

Let me briefly explain the fallacious thinking and misinterpretation of what I said. I have never said we shouldn't have or use ideas. Only that seeing ideas as the ultimate reference is wrong.
What the map-territory relationship teaches us, is that even the very best ideas are partly mistaken and never the same as reality. So like maps, ideas are at best a guide to the world, we should always take with a pinch of salt.
en.wikipedia.org/wiki/Map%E2%80…
As any walker or hiker knows, maps are absolutely valuable for navigation. However, any experienced walker also knows you must never totally rely on the map. A map cannot tell you where there is a waterlogged piece of boggy ground where you will sink up to your waist.

I am well aware that some might consider this as a bit extreme. However, I'm not saying it works exactly like this, but we need some way of understanding how despite all the time and evidence, our so called leaders still refuse to do the right thing.
The latest UN report lays bare the incredible vacuity and dishonesty of the Net Zero by 2050 policy, which is actually putting us on course for 2.7C of warming, nearly double the Paris 1.5C target.
theguardian.com/environment/20…
There is nothing wrong with aspiring to Net Zero in the next 30 years - with 2 big provisos.

1) This has to be actual Net Zero, not fraudulent not net zero.

2) We need rapid and drastic reductions in GHG emissions within the next 10 years to stay on course for the Paris target.
