Reasons to Be Cheerful?

I suppose that we ought to be happy that most new coal-fired power stations, planned since the Paris Accord, are now unlikely to go ahead (https://www.theguardian.com/environment/2021/sep/14/most-plans-for-new-coal-plants-scrapped-since-paris-agreement). Coal is, by far, the dirtiest of the available fuels. It is consequently encouraging that there will not be a major increase generating stations powered by this material. Having said that, some countries (e.g. China and India) do appear to be planning new coal-fired plants. We also need to see many of the existing coal-fired power stations rapidly decommissioned. The same could be said for oil and gas-fuelled plants. We hear a constant refrain about the danger (to jobs, the economy etc) of moving away from coal, oil and gas, too quickly. Escaping from fuels with high emissions consequently seems to be a very slow process. I am not as 'relaxed' as most politicians and industrial bosses. We may not have all the time in the world!
