Climate change is unavoidable (because nature)... but so is human ingenuity. We're constantly discovering new facts and approaches, and this is the major factor doomsayers never bring up in these discussions.
For the first part: not nature, because every carbon emissions today won't have any significant effect until 2040.
For the second part: Yeah, the 2010 drought in Russia was handled so well, millions starved and we're still paying for the political instability it brought in 2011.
And the temperature differential between the troposphere (that warms up) and the stratosphere (that cools down faster than the troposphere warms btw) are becoming more predictible, so when we will have even stronger meteorological events, we might be able to warn the population and to prevent planes to go through them, nice.
And when wet-bulb temperature will be to high, we will be able to grow high-yield plants and harvest them at nigh, while sleeping underground during the day, seems ingenius enough.
Yeah, we will survive, i don't think anybody doubted that. Will the civilization stay the way it is? It won't be the bronze age collapse, but consider this: over 300 year, the Anatolia region lost between 10 and 25% of its precipitations and it almost destroyed 3 empires. Do you think we're that much politically stable?
There's an abundance of new facts, approaches and ideas. And the vast majority of scientists and activists advocate those facts, approaches and ideas. They have been doing exactly that for the past 60 years.
Your human ingenuity counts for nothing if the only ideas that humanity is willing to accept are those which can be marketed to consumers (electric cars, solar panels) rather then those which are boring, maybe even painful to some, but absolutely necessary to sustain life on Earth (sustainable development goals per the U.N. [1])
