-===== In a Nutshell ===== +
- +
-The industrial revolution blossomed on easily-accessed fuels – fossil fuels. Those fuels are all carbon-based. They all produce lots of easily-accessed energy when burned to produce carbon dioxide (CO2). +
- +
-Humans didn't know it to begin with but a carefully-controlled amount of CO2 is necessary to maintain a climate ​that is friendly to life as we know it. The earth, sometimes called "​Mother Earth",​ and sometimes called "​Gaea"​ developed a cooperation between different parts of it's environment to keep CO2 at a level that kept the climate in control for thousands of years. +
- +
-{{:​images:​co2_reflects_infraret.jpg?​nolink&​600|co2_reflects_infraret.jpg}} +

-CO2 (and some other gases) act as a blanket. Sunlight energy enters our atmosphere and bounces off of whatever surface it runs into. The reflected energy is mostly infra-red energy as opposed to the visible light that came in. The CO2 keeps the infra-red energy inside the atmosphere. Increased CO2 keeps more energy in. More energy becomes heat and the temperature goes up. +
- +
-The earth radiates energy as a "black body", and the key information to know about that is more heat is radiated if the body is a higher temperature. So if we have more CO2 in the atmosphere, the earth gets enough hotter that the black-body radiation grows just large enough to balance the incoming energy. +
- +
-The burning of Carbon-based fuels did good things that allowed human civilization to grow as never before. Since doing so was dependent on the availability of abundant energy, and readily-available energy was carbon based fossil fuels, our use of them grew on an exponential curve correlated to our population growth. +
- +
-Thus, our disturbance of the atmosphere'​s CO2 balance went from being a slow disturbance to an ever-growing one. One that has nearly reached limits beyond which life forms such as ours and our food sources may no longer be so well supported on Earth. +
- +
-That's the beginning, but there are more layers. Remember, there was a feedback system that kept things in amazing control for about 800,000 years. This gave humans the "​Garden of Eden" planet that allowed the transition from hunter-gatherer behavior to farming, and cooperative society with lasting communities and aliances. +
- +
-But, our use of those fuels disturbed that premise with secondary consequences:​ +
- +
-  - If temperature changes, it changes how the air carries water. +
-  - If the water in the air changes, that changes almost everything about the weather, because it moves air streams, and it changes where and when rain occurs. +
-  - If atmospheric CO2 changes, so does the Ocean'​s CO2. See [[:​ocean_acidification|Ocean Acidification]]. +
-  - Both the ocean and the ground store huge quantities of methane, which can produce worse effects than CO2. +
-  - Huge changes in the earth'​s ability to support billions of people can come from the resulting:​ +
