Nowhere does the data point to the warming all being natural Krumple. It isn't 'assumed'. It is calculated based on science. If you don't like the science then show how it is wrong.
Show us that CO2 isn't a green house gas.
Show us the sun gives off more energy then our scientific instruments show.
Show us a reason why the CO2 concentrations have gone up and man isn't the cause of that increase.
While your theory is interesting Krumple it doesn't explain known facts.
Fact 1 - CO2 in the atmosphere is increasing
Fact 2 - CO2 increases in an air mixture cause it absorb more IR.
Those 2 facts are simple and have been shown repeatedly. You can't just ignore those facts because you don't want the warming to be caused by humans.
Did you even read what I wrote?
I never said it was the sun.
I never said it was not CO2.
Why are you strawmaning something I never said?
I don't need to show anything. Yet you ignore the one aspect I did state. There is data that shows the earth was averagely warmer in the past then it is now. Not only that but there have been times when the earths climate changed drastically in short periods of time. There is no explanation to why this data exists, there are theories but nothing definitive. Yet people assume that humans are the definitive cause behind today's warming trends. I say that is jumping to conclusions.
Yes COs does contribute to climate change. I won't and have not denied that. But the amount of CO2 that humans have put into the atmosphere is no where near the amounts that volcanoes do. Sure volcanoes don't put out massive amounts yearly but they do over decades or centuries that make up for it annually.
Here is another thing. I remember during the 80s there was a **** load of talk about "acid rain". There were articles and shows and news reports about "how bad it is going to be". They would talk about the rain burning paint off cars and that people would have to wear special clothing to go outside. This was an attempt to cause fear in people so the government could impose restrictions, in other words they were trying to create a new tax.
They imposed restrictions on companies raising their overhead because they now were forced to pay environmental tax to the government to prevent "acid rain". It is all bs. It was so successful for them making revenue that they wanted to create a new tax and this global warming caused by humans is the new trend to create a new tax.
It hurts companies, who get forced to pay, and they can't afford this new tax so they turn around and charge their customers more or lower the quality of their product, or they get rid of jobs by cutting back employee numbers so they can afford to stay in business. This hurts the economy by over regulating corporations. The government knows this so they don't want to impose it on businesses so they will make the people feel guilty instead and get the revenue from them instead of through corporations.
