Global resource rates of supply of nearly everything to each nation-state are being fought over more often as the global demand exceeds the rates that our finite earth can provide. Trade between nation-states becomes unable to rectify imbalances in national resources and production. Continued growth of any large nation-state is direct threat to the resource supply of all others, when global supply cannot be increased fast enough for all. The result now is a trade war between USA and China, as each tries to hurt the growth of the other. As growth is the global economic religion, the restriction of growth of other nations now becomes a goal, in order to continue one's own national-growth.
Australia has taken the side of the USA, and has been doing the USA's bidding, in its rejection of Huawei for 5G rollout. Australian government & society has also been both rejecting and denying the increase in Chinese influence in our trade, immigration and political finance. Australian Coal exports have become a target as part of that war. Coal shipments have experienced go-slow's and now an outright block. Meanwhile GlenCore has announced it will not increase its total production of coal, while we all know that all fossil fuel burning needs to be declining now for a safe climate.
It looks like inter-nation carbon consumption rivalry will do more to decrease total global emissions than any notions of being a good global citizen on the climate emergency, as the quest for growth still takes priority over everything. If the USA and China were serious about fossil fuel consumption reduction, they could plan to reduce their dependency faster than global supply supply limits are going to run out, but no, we have a competition to see who can grow to burn the most in the fastest possible way. Only real supply limits indicate that both cannot succeed in individual growth aims. Each will restrict the other.
Coal is only part of the energy mix, of which 90% is still fossil fuels. Gas and Oil Shipments remain unaffected. Australia is now the official no. 1 global exporter of LNG.
Foreign investments in Australian LNG production are doing well. Gas is an energy substitute for coal, but using gas instead of coal provides little or no long term global heating benefit. Both Qatar and USA will increasing LNG production, to rival Australian exports. Global energy consumption is still increasing, 2% in 2017. In absolute terms, that increase is adding a lot more greenhouse gas emissions, due to the absolute large size of our global economy. Until this global energy economy starts decreasing fast, and soon, all bets of surviving near-future climate catastrophe are off. This requires a large decline in global energy trade.
