A few things here.
1. The climate change "debate" is interesting because it ultimately pits Left wing against right wing ideology. Which is why I am a bit surprised to see Slava on the "right" side of the debate, being a Liberal supporter, you must be more centrist than I understood

. We saw a similar campaign of doubt being played in the 80s and 90s after communism collapsed with the tobacco industry witch hunts. The left v right needed a new battleground, and its gone back to "big v small" government, health/science/energy policy has proven to be a ripe arena.
There is no doubt that the greenhouse effect is real, or that we have been contributing to it, or that it is incredible risky and downright foolish to even be treading the line. There is so much we don't understand. What happens when we get back into a natural warming cycle and the Earth's natural ability to buffer the changes has been compromised by our impacts? At what point does the effect run away and Earth becomes like Venus? Why the hell do we even want to try to find out?
2. To debate our ability to control temperature is a moot point and a red herring. Adapting to a changing planet is something our race will always need to be aware of, and DO, if we hope to survive. Energy policy should be being debated right now, because the energy return on energy invested is dropping precipitously, and when that happens, a society faces a great deal of collapsing pressures. These pressures will be felt in OUR lifetime. We have to provide cheaper, cleaner, safer, more abundant energy to billions more people around the world and INDEPENDENT of the climate debate, this cannot be done with hydrocarbon or renewables.
3. The Oil ETF discussion was interesting a few days ago. For those retail investors who fancied themselves clever for being involved in them are being
reminded today why you shouldn't go up against institutional investors in a rigged game. I am beginning to suspect more and more that the massive drop out in oil price is a market struggling to convert from being demand driven to supply driven, amplified by market manipulations, super rapid derivative training... or as they say in the link "oil is the new subprime".
