If Newton's 3rd law applies,For every action, there is an equal and opposite reaction. then the imbalance will balance it self eventually, either human perish and then cool down or so much ash generated from the steel mills that blocks the sunlight and we go back into Ice Age 2.....whoopie...

From what I understand from National Geographic human creation is still very insignificant compare with volcanos (especially those under the sea), if Lake Toba blow up again like before, we will definately have Ice Age 2. The people will buy more Abterra & Straits Asia coal to keep warm.. hahah..no sun the wind dies, the solar panel inactive, left only nuclear, fision goes out of control, blast the earth & stirr up a lot of dust, we get another Ice Age...I say buy...to keep warm during Ice Age 2.

China wants to cut pollutions and is moving away from  such energy production as coal.

Steel production needs coke but  technological advancement may come out with other alternative to do it without or lesser coke.

Nuclear energy is the way to go, even Singapore  have already contemplating to go nuclear........ and almost every of our neighbours are also going  for nuclear energy........... :)

Coal's demand currently still there.........but its dwinding........and eventually.it would be like dinosaurs.( but not so soon)

But the writing is there............." Fission" technology where water is an ingredient to produce large amount of energy..... if successful will  eventually put coals usgaes in the museum where future generation look at it and ...... laugh  and wonders while  such things was used then...... its like when we look at  those days before electricity was invented.... how  those ppl then live..  We were amazed and puzzle  but that s the way it was then.  candles are really important.. for night view. Now we have led touch lights. Its technological advancement that  change the way We live. The value and demands of raw ingredient decrease  in time..........when advancing technology replaces them. For coal, the writting are on the wal already. :)
