We need to reform our monetary system. Credit generates money, which is supposed to represent actual created wealth. In order to obtain credit, social agents have to convince banks and nation-states that they will create actual wealth in the future. Thus, money is created in advance of wealth and is attached to an expectation of growth.
The financial system has always been broken and it's incapable of dealing with the climate crisis. These researchers know how swiftly we must take action for a civilization to exist at all in the next few decades. Global economy has only one possible future apart from annihilation, which is to stop emitting greenhouse gases and to start capturing carbon. That project and all it entails should be the promise that generates new money, since any wealth will be rooted in that endeavour. Money is the soul of an economy, and ours is based on colonialism, slavery, exploitation, expropriation and wealth concentration, that's why the world worships the US Dollar.
You have a point. India and Pakistan are out of the Security Council because they are underdeveloped and are busy having their nuclear missiles aimed at each other. North Korea has at most only a couple of ICBMs and is unable to destroy our entire civilization, even though it can create a lot of destruction with those. That is the most troublesome of nations for the UN, because they don't give a fuck about rules and are slowly increasing their bellic power, thus all the fuss about them improving their nuclear program with the help of Russia. Geopolitics is fun.
