Our current warming trend goes back about 200 years to what was known as "Little Ice Age" and it started before the invention of cars and planes. The world averaged temperatures a few degrees Celsius higher than today during a period 6,000 years ago during a period known as the "Holocene Maximum." Climate change is cyclical. We will see a time in our history when temperatures are both warmer and colder than they are today.
The harsh reality of these facts presented here is that so much economic development has taken place based upon the false sense that human CO2 is causing us to burn up. Tens of thousands of jobs have been created in this industry all over the world. Solar and wind power implements for instance take many years to break even if they ever do. Although the job creation is good, these industries will crumble when it is realized that human CO2 emissions are not the culprit of global warming as these technologies are not cost effective and heavily subsidized.
