Historically Responsible (But Maybe Not In a Responsible Mood)?

Naturally, people have asked which nations have the greatest responsibilities for our current climate emergency? Carbon dioxide is a potent (but not the only) 'greenhouse gas', responsible for global heating. The gas persists in the atmosphere for many years. Carbon Brief, have attempted to identify the culprits, by totalling carbon dioxide emissions of all countries since 1850. 1850 is roughly the start of the UK's Industrial Revolution, when burning fossil fuels 'took off'. The carbon dioxide emissions from all sources were totalled, namely burning fossil fuels, deforestation, land-use change and cement production (https://www.theguardian.com/environment/2021/oct/05/historical-climate-emissions-big-polluting-nations). The top 10 (roll of drums!) were the US; China; Russia; Brazil; Indonesia; Germany; India; the UK; Japan and Canada. Contributions to emissions varied widely. For example, the US and China generated 85% of their emissions by burning fossil fuels and circa 15% from deforestation. These percentages were largely reversed in Brazil and Indonesia. Deforestation essentially took these last 2 countries into the Top Ten. Interestingly, deforestation has also rocketed Australia up the charts into 13th slot. That country removed 50% of its trees over the last 200 years. Worryingly, of the Top Ten polluters, only Canada; Germany, the UK and the US have made ambitious sounding new pledges to cut their 'greenhouse gas' emissions, before the COP26 meeting in Glasgow. A pledge is, of course, not the same as achieving any self-imposed target. A pledge, however, is better than nothing or only agreeing to make fairly meaningless changes to emissions. A number of national 'so-called plans' have been deemed by experts to be totally 'inadequate' or 'vague'. The world has already used 85% of its carbon dioxide budget, to limit global heating to 1.5 degrees Centigrade above pre-Industrial levels (about 1850). The 'snail-like' speed in the world's response to climate change, is clearly evident in estimates that 67% of the carbon dioxide, produced by burning fossil fuels, has belched into the atmosphere since 1980. Forty percent of emissions have occurred since 2000! Reducing emissions now would have a big effect. It is obvious that curbing climate change is in everyone's best interest. Truly global action is needed, especially from all Top Ten of the big polluters. Countries failing to 'do their bit', will make it impossible for the rest. Humans get very resentful, when they are making sacrifices, whilst others carry on regardless.
