Sorry, Tim, I have to disagree.
Battery electric cars are a transient and useful step, but they are not the long term solution.
Which is what I was saying, so no disagreement there
Hydrogen is the only non carbon based liquid energy store that will allow travel as we know it to continue. It can power fuel cells, jet turbines and, internal combustion engines. Batteries are expensive and polluting to make, heavy and have re-cycling issues.
Global warming, and its consequences, is not going to be slowed by focussing on reducing CO2 output from automotive transport in developed and developing countries.
No disagreement there either
IF Ms Thunberg and her friends at Extinction Rebellion are right, radical change is needed, NOW.
Don't forget the 97% of the world's climate scientists, and an enormous body of data that supports the models. Greta Thunberg simply wants us to follow the science, not the politics.
Immediately stopping the mining of coal and fossil fuels and its burning to make electricity, steel, chemicals and so forth, coupled with the banning of all forms of air and sea travel that use fossil fuels will do it.
The resultant social chaos, economic collapse and global pandemics will return our CO2 levels to pre-industrial revolution levels.
I'm glad I'll be dead before that happens.
This must be where we disagree. I don't believe we need to go back to pre-industrial primitivism, I believe we need to focus technological development on alternatives. But whatever happens we are indeed going to see a big change in our lifestyles over the next 20 years.
