Everyone knows temps have risen since 1880.
Exactly how bad has it gotten?
Life is good. A warmer planet is good.
What is your ideal temperature and CO2 Level?
It's not just a little warming. If you knew anything about it at all you would know that. But it's clear that you are extremely ignorant and deluded about it. A steady diet of Fox News and Breibart only will do that to a person.
This is what will happen. How much and how bad depends on what we do now.:
Species extinctions from rapidly changing conditions. Manmade and natural sytems are adapted to certain conditons. When they change those systems suffer. This means agricultural and ecosystems.
Sea level rise, flooding of coastal areas drownings, reduction of coastal marshes which are important to sea life.
Equatorial and other areas becoming so hot that humans die from the heat.
Flash flooding from heavier precip events leading to death and destruction.
Stronger storms hurricanes leading to destruction and death.
Drought leading to wars death and destruction.
Extended frigid polar outbreaks that remain in place resulting in death and destruction.
Warming and acidification of the oceans resulting in coral reef death and reduction of the oceans productivity causing hunger and death.
In a nutshell.....death and destruction.
