Droughts followed by famines will become the order of the day in most of the world, wars will be fought for access to water, refugee crises the likes of which haven't been seen since for maybe 2000 years, greatly increasing the risk of nuclear holocaust (which is already at an all-time high, with the USA unilaterally withdrawing from its treaty with Russia, and exploring low-yield nuclear weapons), the rise of surveillance states now becoming possible to a degree that was barely even dreamed of before our time, a (mild) global pandemic showing how brittle our systems are and how much our leaders are willing to put economic benefit ahead of human life, the new rise of fascism in the US and Europe - we are well on the way to the worse centuries in recent human history.
Make no mistake: there is absolutely no doubt that climate change, on its current unchecked path, will end human civilization as we know it. That is not to say that there won't be a human civilization in 100 years, but there is no way for the current system to resist flooding of some of the world's largest cities and other densely populated areas, probably physically displacing more than 500 Million people, heat waves that will kill a healthy adult in the shade in much of the warmer regions, extreme weather events becoming increasingly common and more severe, and all of the consequences of these items - drought, famine, wars over land and drinking water, massacres to contain the migration of the hundreds of millions of people that will be displaced.
And of course, essentially every dollar of GDP growth that we currently make is only increasing the problems above, and will continue to do so on the current path.
The only way to avert the catastrophe is to drastically change our civilization today - to stop burning any fossil fuel or methane gas today, literally (yesterday would have been better), and take on all of the major economic overhaul that entails. Every day we continue to burn fossil fuels, to raise livestock in industrial numbers, to burn down forests etc is increasing the magnitude of the catastrophes to come (it is too late to completely avoid catastrophe, we can only hope to make them milder).
