What are some arguments that global warming is not caused by humans?

Answer 1

There is ample evidence of global warming and cooling in the remote past, long before people started burning fossil fuel. But that dodges the question of whether or not we are exacerbating the most recent natural warming trend.

Answer 2

The evidence is fairly simple. Historically a cycle of warming and cooling of about 600 to 650 years was recorded from the second century BC. Cooling was recorded as pushing the Romans South from Europe - The Danube froze allowing hostile tribes to attack Roman outposts about 100AD. Crop data preserved from 1100 to 1200 AD indicated subtropical climate in parts of Great Britain. The Little Ice Age is recorded as beginning with terrible famine in Europe to 1500AD. The Little Ice Age ends about 1850AD: 1826 is the coldest year on record in Europe. Warming has been recorded ever since 1850.
Recently Solar Scientists have published observations that indicate a Solar Cycle that confirms the historical observations.
This is not to say that man can not have an influence. Pollution effects Global dimming and that should have a significant cooling effect. The increase in greenhouse gasses could be expected to have a some effect on warming. However we must realise that even without our intervention Global Warming would have occurred, perhaps at a slower rate.
It is not clear that the maximum temperature will be influenced one way or another. The arguments against man's influence should only be used to caution against optimism. Reducing Carbon Dioxide may have little effect at a great cost to humanity, particularly the poor. On the upside it is clear that Nature is adapted to these periodic fluctuations.

Answer 3

It isn't so much an argument as a simple fact that the global temperatures go through cyclic changes no matter what the panic mongers want you to believe. And no matter what the panic mongers want you to believe, there is nothing that demonstrates global climate change is caused by alleged greenhouse gases generated by man. All the evidence points to it being a natural occurance.

Answer 4

The main thing is they blamed it in green house gas knowing that most people would not know better. When they tied in CO2 because they thought that u were burning too much fuel. Mother nature has recycled our air for millions of years. Well it is really the plants through a process of photosynthesis. The plants have don a great job and there has been no increase in CO2.With the CO2 the rest of the green house are so small it is near impossible that they affect anything.

Answer 5

My name is Rafael Lomena. I write from Alicante (Spain). I am independent investigator on the Accelerated Global Heating and want to share with all something that can turn out from interest to fight this phenomenon.
I believe that the main cause of the Accelerated Global Heating is in the great and increasing forest fires that are whipping to the planet in the last years.

Answer 6

The interesting question is why everyone is so focused on CO2, which is less than .2% of the earth's atmosphere. The other greenhouse gas, which gets no attention at all is water vapor, which has a concentration 70 times higher in the atmosphere.

But you can't attract much money or notoriety by proposing to someone that you want to study water vapor, and it is hard to find someone to blame for its concentration level.

Answer 7

I don't have the link, but in any search engine, search for "climate change". On the later pages of the search results you will start seeing studies that show that the Earth goes through hot and cold phases naturally.
