What do “carbon emissions” have to do with climate change, anyway?
Increase (or decrease) of carbon dioxide has little to do with average temperatures around the globe, and it does not correlate with either an increase or decrease in climate events, such as precipitation, or length or degree of winter conditions or tropical conditions that may prevail, or in average sea level, or much of anything else. The effect is far too diffuse and uncertain.
The big controlling factor of overall average earth temperature and its effects on the atmosphere is not, and cannot ever be, the rather minute amount of carbon dioxide in the atmosphere. it is water vapor, which has a HUGE moderating factor on atmospheric temperature throughout the course of a day, a year, a century, and millennia.
What makes up glaciers? Frozen water.
What makes up oceans? Liquid water.
How does the water get from the oceans to the glaciers?
Understand that cycle, and you have some inkling of WHY there shall never be either runaway cold or runaway heat temperature fluctuations over short periods of time.
It is all Reagan's fault. Seriously.
Back before Reagan, the environmental left focused all their attention on real pollution, i.e., substances that are poisonous to life and that are not naturally in the environment. The solution was more government control.
Then the Iron Curtain fell and it became obvious that the countries with the most government control - The Soviet Union and Eastern Europe - were all environmental cesspools. Meanwhile, as countries turned to capitalism and became more prosperous they also started cleaning up their pollution. Basic Maslow's hierarchy of needs. When you don't have to worry about feeding your children you start worrying about cleaning up your environment.
So the environmental left turned to carbon dioxide - a totally natural substance that is necessary for life on Earth. Why carbon dioxide? Because successful capitalistic countries produce more of it per capita than failed socialist countries. If you have a high GNP then you produce more electricity and naturally produce more carbon dioxide generating it.
The solution of course is still the same. More government control.
Nothing. But. A communist like Sanders will get to the point of revealing how he wants us stop breathing to help control CO2. I wonder if the dufuses that follow him even know they exhale CO2 and the subsequent correlation to their breathing and their cause?
