Now do you see any correlation between the industrial revolution and the increase of greenhouse gasses in the atmosphere?
Now, here's a graph of the average global increase of temperature over the last 2000 years
 Now considering the effects of greenhouse gasses on ozone, do you see any correlation between the two?
And before anyone says that a global temperature increase of 0.6 isn't important needs to read a book.  |
2000 years means nothing on the geological timescale of the earth It's ridiculously short sighted and there is a possibility that people and scientists could be deriving causating separate phenomena from incomplete evidence that are merely correlations.
For most of the holoscene, human civilization has developed during an interglacial period with periodic rises and dips in temperature that often mirror the same things we have seen in the past 2000 years.
The rise in industrial emissions and the resulting correlation of a change of a few degrees could simply be coinciding with a period of change in solar output or solar activity or other geological or meteorological phenomenon that is not as easily charted and graphed for the masses to consume.
Prior to the 20th century, the earth was in a little-ice age since the 16th century. Prior to that was the Medieval warming period in which temperatures could be interpreted to coincide with the warmer temperatures we have now.
If you want to post data causating emissions with climate change, please use a longer scale than 2000. About 60 million years is more appropriate as the Paleocene was the start of modern fauna which confer the greatest effect upon the carbon chemistry in our atmosphere.
If you do that, you'll find that there have been countless significant rises and falls in global temperature, often just as rapid, over thousands and millions of years without humans even existing on this planet to create carbon emissions.
Anyone that says that a global temperature increase of 0.6 is so totally transparent and 100% caused by man needs to read more than one book.
Look, I can post graphs too which show something remarkable with large emotional response! I will not however, claim that this is a definite proof with 100% scientific accuracy to predict our future.
