You fail to really understand Zymu.
The Earth goes through cycles. Warm, cold, warm, cold. We have been warming since the end of the last ice age. During that short period humans have flourished, greatly multiplied, and spread across the planet. We invented some cool stuff too!
Warming will happen with or without us given the normal cycles. Some things can accelerate that, or even reverse that. Emissions from massive volcanic eruptions, hitting the earth with a big meteor and raising massive dust clouds, etc. World wide burning of fossil fuels. Some of those are natural, some are not.
The only thing up for debate is how MUCH humans contribute, not that the fact the the Earth is warming - and will continue to. We can’t stop it.
Maybe we can slow it by removing the portions that humans contribute? Maybe?
Regardless, it WILL happen just like it has been happening since the last ice age ended. Then what?
-Changes to weather patterns. While overall warming is the average trend, changes to ocean currents, rainfall, etc can create weather extremes. Super cold spots and super warm spots. Intense rain, intense storms, etc. We have seen that. IMPACT - critical infrastructure, military, ports, transportation, and populations need to build and plan based on resilience to extreme weather. Some people will have to move.
-
Rise of sea levels. IMPACT - again, ports, military, major cities, housing centers, transportation (locations of airports, trains etc), need to adjust - or plan ahead. Don’t waste money on building something in an area that will be flooded in 30 years.
-
Impact on growing conditions. Crops in some places will fail. Others will become fantastic farming areas. This is quite critical - food drives economies, stability, and population movement.
-
Secondary to that - water. As climate patterns change access to water will remain critical - and places that depend on it now won’t have it. Again, this will result in strife and population movement. Just like it has for thousands of years.
The issue is not that the Earth is warming. YES it is and has been for thousands of years. The part humans need to care about is - how fast, how can we adapt our critical infrastructure and resources, and is there anything we can do to slow it down and buy time to make those changes.
No, the Earth is not going anywhere. How happy humans are on it though is an open question. Dinosaurs had a good run too, until they didn’t.
