what are some reasons that global warming is natural and not caused by humans?

Question

im doin a chemistry project. and the topic is "global warming is a natural phenomenon not caused by the activities of humans". what are some reasons for that topic and facts. how do i prove this in my project?

Answer 1

Dear Mr. Cheney,

Isn't there a friend you can take hunting or something? You can't make this issue go away.

Answer 2

Yeah, the Ice Age was in no way caused by humans. Also, the regular chemical weathering of rocks releases trapped gases into the atmosphere, such as CO2. When a rock is formed (or sediments deposited and "cemented" together), gases and chemicals in the matter that gets included in that rock are trapped. The deposition and weathering of these rocks greatly affects the amount of the "greenhouse gases" that are present in one of two reserviors (ground vs. atmosphere). The processes of weathering have been around since the earth formed, definitely no way humans could have had anything to do with it. Hope this helps, if you have any questions, I have some really good textbooks I can consult for you.

Answer 3

One of the easiest ways is to find the science that show temperature hikes before rises in CO2 levels, which is a fact. With that being said, then CO2 is a byproduct of global warming not a major cause and that can be seen in temperature hikes and falls through the centuries.

Also, seeming that CO2 is NOT the major greenhouse gas, you could focus on water vapor, and any changes in water vapor levels in relation to global warming.

Finally, look into recent science on climate change occuring on other planets and that the sun is the reason that climate change is happening on those planets as well as Earth.

Answer 4

If you look at temperature reconstruction from ice core data in both antarctica and greenland (see the attached link,) you'll see that the temperature has been constantly rising and falling over the observed period. In fact, if you look at the charts for the last 10,000 years you can see that the antartic temperature were warmer than present as recently at 400 years ago, and that there were many temperature rises that were warmer than present over that period. In addition, the antarctic temperature data shows warming rates that are much faster than the current warming rate. You can see a warming rate of 2.2*C in a century around 400 years ago - compare that with the 0.6*C rise that the earth saw over the last century.

If you look at the greenland temperature data, you will also see many warming and cooling swings over the last 10,000 years. Most interesting about the greenland data, however, is that it shows that the greenland temperature has been warmer than present for MOST of the last 10,000 years.

All of the warming and cooling trends indicated by the ice core data occured without any man made influence, and yet caused warmer temperatures and faster warming rates than we are presently seeing. These were natural (not man made) events. It stands to reason that the relatively minor warming that we have seen over the last century is then also a natural event.

Answer 5

It shouldn't be that hard. All the credible scientific evidence supports the fact that it's a natural cycle.

look up the "global warming swindle" on youtube

Will provide some real science on the problem for a change.

Beyond that all you need to do is point out the Earth's history of climate shifts.

Answer 6

One reason is that the sun's output has gone up by .2% in the last 40 years and Mars and Pluto are also heating up. Read all about it in a 2003 article that everyone chooses to ignore.

Answer 7

worldwide warming ahould be a organic technique. yet because of the eco-friendly homestead result or the carbon footprint left at the back of from human beings, the worldwide warming technique is happing swifter than this is going to. Som to respond to your question, it rather is a organic technique and human beings can strengthen the effects of world warming.

Answer 8

not to say we have no part in it, but the earth has always gone through changes on it's own. Ice ages, hot ages, before humans even existed. the earth is going to change regardless of us, we are just helping speed it along.

Answer 9

You'll have a hard time proving it, since scientists with PhDs and all the money in the world haven't been able to prove that. The vast majority of the evidence and of scientists point towards global warming, as we see it today, being a man-made phenomenon.

Answer 10

many scientist say that its a phase that the earth is expierienced just like the way earth once had an ice age. humans couldnt have caused the ice age.

Answer 11

Because the Sun can go up to 11.
