A catastrophic climate event is upon us. Here is why you’ve heard so little about it | George Monbiot

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
The part about the economist which "modelled" the impact of climate change and came up with hilariously optimist results that aren't anywhere close to those from the Scientists from hard-sciences is just so typical.
Economists lying with models (i.e. basically using Mathematics as a layer of complexity hidding purposeful lies, so as to deceive those with little familiary with the Scientific Method or modelling) is THE main tool that has been used to push Neoliberal politics for 5 decades and created the shit we're living in.
I worked in Finance and am intimatelly familiar with how you can make Mathematical Models to produce whatever the fuck effect you want: mainly by the formulas you chose for your model and by chosing what types of inputs it takes you can make a "machine" which will produce a specific fable from genuine real-life data.
Mind you, the Scientists and other people with Science Training won't be deceived, but that doesn't matter because those "models" and their "results" (generally produced in Think Tanks funded by the very people whose interests are, by an amazing coincidence, served by politicians acting as if the model is genuinelly representative) aren't meant to convince domain experts, they're meant as technocratic "arguments" for articles and opinion pieces in the Press to sway public opinion (or at the very least spread doubt on the consensus of the actual domain experts) and as a cover for the bought up politicians to chose the policies benefitting the interests of those who are or promise to be "good friends" to them.
