The world is losing the war against climate change

However, we already lost it - in a very real sense - because we failed to convince enough humans that it's important, that they ought to demand tougher legislation, policies, treaties, mandates, cleaner air, better waste management, more energy efficiency, instant order of nuclear and renewable plants to phase out CO2 producing energy sources as soon as possible, etc.

We should be building 20km long hydro T-s, electrifying more and more railways, capturing as much emission as we can (chemical plants, big freighter ships, etc.)

Instead we are building walls on borders, blabbering about secession, killing/jailing/maiming/kidnapping/torturing each other in an organized fashion all around the planet.

We're simply late to efficiently manage a lot of things.

But humanity is very likely to survive, so in that sense as long as someone can ask that question we don't have to use past tense.

The vast majority of people who believe climate change will have large negative consequences make no major changes to their lifestyles. As someone who rides bike for transportation largely to save money and stay in shape (I think climate change is a lost cause), the environmental crowd seems to think I am doing something saint-like. But it really isn't anywhere near as difficult as they believe. They rarely adopt cycling to work, and at least part of the reason why seems to me that their environmentalism is not entirely sincere. This is speculation, but I think most people stop at signalling that climate change is bad. They rarely take effective action.

ELI5: if the temperature of a wet thermometer(which would normally be colder due to evaporation) in a given place goes over around 31C this area becomes uninhabitable for almost all mammals.

Burning all the known fossil fuels would be enough to make it so for some places on earth, but the big unknown is what about the other sources of GHG's like thawing permafrost or clathrates lying under the sea?

As such - when wildfires start (regardless of origin of the fire), they tend to spread more rapidly and more intensely.
