Personally, I hold the same view of climate change that I've had as long as I've been aware of it.
Humanity isn't yet advanced enough socially and in collective maturity to take the necessary actions to stop climate change.
We're still part animal, part sentient, and we don't know where that line lies, much less control which side we're on all the time.
All we can do is understand what the impact of climate change will be and plan to survive if we can find a way to do so.
Within the next century we are definitely going to have:
* Massive numbers of displaced people due to rising seas, excessive heat, lack of water, lack of food. The bulk of these people will die.
* Existing countries that do not or can not take steps necessary to safeguard their population sufficiently to maintain their economy, military strength, and the logistics that support it are going to undergo major changes, possibly including dissolution or massive shrinking of borders.
* The wealthy of the world will not lack anything, be it food, water, housing, cooling, military protection, etc. The weakening of governments across the world will allow these people more power and freedom than ever before. We may enter a new age of kings by other titles.
The world at the end of the next century is going to be vastly different from the present world. Humanity will survive, but that's setting the bar low. Many humans will die, many ideals will die, and we may not learn anything from all of it. In other words, humanity will be the same as it's been through all of recorded history.
