I had linked what I thought was a YouTube recording of Greta Thunberg addressing the Austrian World Summit in this blog post. Well, apparently either someone substituted a different video for the talk or edited or cracked it so Ms Thunberg is replaced after about a minute and a half with some Austrian leader or businessman rambling on incoherently about something which occasionally has mention of climate.
Accordingly I replicated the address which Ms Thunberg posted on Twitter, put it in safekeeping, and now have replaced the broken YouTube presentation with the proper address.

Greta’s essentially correct.
To date there clearly has been inexcusably insufficient political courage and will to properly act upon the cause-and-effect of manmade global warming thus climate change. Without doubt, mass addiction to fossil fuel products helps keep the average consumer quiet about the planet’s greatest polluter, lest they feel like and/or be publicly deemed hypocritical. It must be convenient for the industry.
The industry and corporate-orientated governments can tell when a very large portion of the populace is too tired and worried about feeding/housing themselves or their family, and the virus-variant devastation still being left in COVID-19’s wake — all while on insufficient income — to criticize them for whatever environmental damage their policies cause/allow, particularly when not immediately observable. (In fact, until recently, I had not heard Greta’s name in the mainstream corporate news-media since COVID hit the world. That is not good.)
Also, as individual consumers, far too many of us still recklessly behave as though throwing non-biodegradable garbage down a dark chute, or pollutants flushed down toilet/sink drainage pipes or emitted out of elevated exhaust pipes or spewed from sky-high jet engines and very tall smoke stacks — even the largest toxic-contaminant spills in rarely visited wilderness — can somehow be safely absorbed into the air, water, and land (i.e. out of sight, out of mind); like we’re inconsequentially dispensing of that waste into a black-hole singularity, in which it’s compressed into nothing. …
Still, it’s great to have Greta back.
