Is Global Warming being caused by us?

I will be the first one to say that I don' know if "Global Warming" is being entirely caused by the human race or not. I believe that the earth goes through cycles and we may have entered a cycle where the average temp world wide is rising. Depending on where you live yes it may be hotter than normal but where I am it is cooler than usual for this time of year. So as I have asked my wife, if Global Warming is real why are we so are under the normal average temp for this time of year. And it's not just this week or even this month, it's been almost the entire summer with the exception of maybe a couple of weeks. Right now as I write this the temp is 63, the average high for today according to the weather is 79. So right now we are 16 degrees cooler than normal....doesn't sound like "Global Warming" to me.



I understand that you cannot just look at a day, a week, or even a month. You need to look at the BIG picture. I also understand that from one year to the next that there will be a difference in the temp. With that being said who can say (besides Al Gore) that Global Warming is occurring or not. There will be differences from year to year.



We have not been keeping a written record of the temps for only about the last 160 years. That may seem like a long time to you and me but for the Earth that is not very long at all. You may be able to find some records that go back further than 160 years ago but even if you were able to go back 2000 years it still would not prove or even disprove whether we are causing global warming. The earth is around 4.54 BILLION years old. So all you would be able to do is go back less the .00005 % of the time that the earth has existed. Not very long to be able to prove anything.
