Man-made Global Warming: Facts & Evidence?

Here's a good one:

No offense Dana, but where is the proof that the #1 green house gas is not the driving factor? So far no scientist has come out and explained the effects of water vapor on climate change especially since water vapor makes up a grand total of 95% of all green house gases and only 1% of the 95% is man made. Also from my understanding all the charts and statistics show that CO2, methane, and other green house gases lag behind temperature change not drive it. Can the man made crowd come up with any proof that doesn't ignore past climate history, doesn't use computer models that dumb down the Earth into one variable or few variables causing climate change? Finally, how does the fact that man's total contribution to green house gases is at most 3% driving the climate change off of a cliff? For the person bringing up peer reviewed articles again, all that means is that people agree with your work, not that it is accurate or good science. There is a big difference and the scientific community has gone away from doing real research into doing research that brings in the most money. I have family that are into scientific research.

For accurate information and reasoned judgments by qualified experts on this question see the "Deniers" series published over the past 2 years and available in book form or over the internet (free) from the National Post newspaper, Canada.

"Global Warming," is actually just a warming trend in the continuous cycle of the earth. The earth has gone through about eight major ice ages throughout its history and we are on the downtrend of the latest one which is why the earth is naturally getting hotter. Human beings contribute less than .06 percent of the total greenhouse gases that are entering the environment and we are not having any kind of a significant effect on the overall temperature of the earth.

From the link

"Despite increasing amounts of CO2 gas in the atmosphere, mean global surface temperatures have not shown any increase over the past 18 years."

Which is an out and out lie.

2014 is not over and a time frame ending in 2014. 1997 to 2014 includes up to December 31, 2014.

If you want to quibble about the exact timeline, the person making a claim about no warming in any given time frame means no warming since a given time, he/she should state an exact start date for the lack of warming, or expect people to analyze data up to the end of the year before he/she makes the claim. So a stand by my 1995-2013 timeframe to check his claim.

Other problems with the claim is that even with your adjustments to my graph is that not all all datasets show a lack of warming since 1997.5

Another problem with your "corrections is that the time from July 1997 to July 2014 is 17 years, not 18 years. I am not going to waste my time discussing a more exact time from July 1997 to September 2014 or from July 1, 1997 to October 18, 2014.

Another problem with requiring such precision with dates to make a claim of no warming is that the issue is actually a case of signal to noise, or in other words, weather, rather than an actual lack of warming.

The recent warming trend, commonly referred to as global warming, perfectly coincides with the Modern Maximum (the greatest solar activity level seen in over a thousand years).

You might check out Bill Gray.

"William M. "Bill" Gray is a pioneer in the science of forecasting hurricanes. In 1952 he received a B.S. degree in geography from George Washington University, and in 1959 a M.S. in meteorology from the University of Chicago, where he went on to earn a Ph.D. in geophysical sciences in 1964.

Gray pioneered the concept of "seasonal" hurricane forecasting—predicting months in advance the severity of the coming hurricane season.

Gray is Emeritus Professor of Atmospheric Science at Colorado State University (CSU), and head of the Tropical Meteorology Project at CSU's Department of Atmospheric Sciences. Gray is noted for his forecasts of Atlantic hurricane season activity.

Gray served as a weather forecaster for the United States Air Force, and as a research assistant in the University of Chicago Department of Meteorology. He joined Colorado State University in 1961. He has been advisor of over 70 Ph.D. and M.S. students. His team has been issuing seasonal hurricane forecasts since 1984.

He is a controversial figure in the global warming debate, as he does not subscribe to anthropogenic causes for global warming.

Gray is skeptical of current theories of human-induced global warming, which he says is supported by scientists afraid of losing grant funding and promoted by government leaders and environmentalists seeking world government. He believes that humans are not responsible for the warming of the earth and has stated that "We're brainwashing our children." He asked, "How can we trust climate forecasts 50 and 100 years into the future (that can’t be verified in our lifetime) when they are not able to make shorter seasonal or yearly forecasts that could be verified?"

Gray said those who had linked global warming to the increased number of hurricanes in recent years were in error. He cites statistics showing that there were 101 hurricanes from 1900 to 1949, in a period of cooler global temperature, compared to 83 from 1957 to 2006 when the earth warmed.

"They've been brainwashing us for 20 years, starting with the nuclear winter and now with the global warming. This scare will also run its course. In 15–20 years, we'll look back and see what a hoax this was."

Real, mostly caused by us. The proof is far too massive for here, it's in the links below.

This is science and what counts is the data, not people's intuition.

"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

Vice Admiral Richard H. Truly, USN (Ret.)

Former NASA Administrator, Shuttle Astronaut

Here are two summaries of the mountain of peer reviewed data that convinced Admiral Truly and the vast majority of the scientific community, short and long.

There's a lot less controversy about this is the real world than there is on Yahoo answers:

http://www.worldpublicopinion.org/pipa/articles/ho...

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

http://en.wikipedia.org/wiki/Scientific_opinion_on...

http://www.sciencemag.org/cgi/content/full/306/570...

EVERY major scientific organization has issued an official statement that this is real, and mostly caused by us. The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.

The "solar activity" correlation discussed above falls apart completely about 1980.

"climate science from climate scientists"

I'll have to disagree with the last answer. While it is true that there have been several ice-ages, according to various scientist that have been on NBC, Discovery Channel, Science Channel, etc, we are suppose to be heading back towards an ice age at this point, and all the evidence shows we are much hotter than we should be. If you look at when this trend has been hapening, it's been since the industrial revolution.

While many people believe it's a natural occurence, they all seem to be on yahoo answers, but none of them seem to offer any concrete evidence. Of course these are probably the same people that think if you like the environment, you must be in love with Al Gore.

Try to look through available videos, if you can find one that counters global warming, I really would love to see it.

True, I haven't read alot about global warming but I'm a sucker for documentaries and I believe the movie The 11th Hour is a good one.

I wrote a wiki article on the subject linked below. It contains links to my sources.
