Here's the logic: Scenario A: We spend a ton of money and resources on combating climate change. Energy and fuel become more expensive. There is economic crisis in some areas of the word. There is large scale refugee migration. Some small proxy wars break out. We manage to stem climate change and even slightly reverse it back to a natural level. We keep our modern technology. We keep most of the cultural status quo. Maybe a couple hundred million people lose their lives due to indirect consequences. The Earth still spins. Coastal cities aren't underwater. There is no global famine. Climate change skeptics will complain that combating climate change was a bad idea because they didn't see the worst of it. Scenario B: We decide to not try and combat climate change. We don't spend any money on it. We think "everything will work out". Everything goes on just like normal for a few decades. Climate change skeptics are saying "I told you so." The economy prospers. Technology improves. We continue our dependence on fossil fuels, continuously pumping carbon into the atmosphere. We continue dumping waste into the ocean. The permafrost continues to melt more and more every year. It's all so gradual that barely anyone notices. Coastal cliff faces in California start eroding and taking beach front property with them as the sea level rises. Farms at lower latitudes start having more and more of a difficult time producing good yields. There is less snow falling in the mountains meaning that come spring time there is less melt. This causes droughts in many parts of the world. This drought starts to impact farmers. The global food supply dwindles. We are noticing massive numbers of oceanic lifeforms start to die off. Fisheries are not able to keep up with the demand. There isn't enough feed for livestock. The global food supply falls even lower. The drought is getting worse over the years due to less snow melt. Smaller countries with sub-par infrastructure start seeing a massive exodus of their population. These refugees migrate to large developed nations causing cultural strife and putting a strain on their economy and food supply. This cultural and economic strain leads to warfare. This warfare leads to even larger migrations. Soon we have world war 3 in the midst of the greatest global famine and drought the world has ever seen. Billions of people die. Human civilization as we know it is destroyed. We regress culturally and technologically. This is just one set of possible scenarios. So, I ask you; Why not spend a little bit of money now and avoid what is essentially the apocalypse later? Let's say I'm wrong. Let's say scenario B could never happen and climate change isn't as bad as we think it is. Well, you have insurance on your house, don't you? Your car? Think of combating climate change like car insurance. Even if an accident is unlikely, it's still nice to know that you have it covered if it does happen.
