Its literally like in the movies no one cares until its too late. I follow/ been following this pretty close since i was a teen , always been a subject of interest of mine and the scary thing is that scientist/experts have been 100% right ever step of the way. Even more scarier is that things have been accelerating quicker than they predicted. Here in the next 5-10 years what we will start seeing is just mass famine in most of these underdeveloped countries, with thousands starving to death on a weekly basis due to lack of food/water.
In semi developed countries power structures/dynamics will start to shift because climate change will change what they can produce/provide for there people, but they will barely hold on.
In developed countries like here it will be a slow bleed combination of both that will play out over a 20-30 year period. I can tell you right now if your someone young living directly on either of the coast start to think about moving towards the middle of the country. I did years ago and climate change was at least a 25% influencer, not saying climate change wont affect here but between rising sea levels , hurricanes and over population. I wouldn't want to be in either of the coast when these yearly large disasters start hitting.
