Why would anyone believe in manmade global warming?

[reno]

24 of the 50 US States had their highest ever recorded temperature in the 1930s

 

Global temperatures declined from 1945 through 1979, yet his was a period of rapid industrial expansion and increasing CO2 production throughout the world. If CO2 and temperatures are linked, why did temperatures fall?

 

 

Global temperatures have declined in five of the last seven decades even though CO2 levels increased throughout this same period.

 

earths temperatures are not constant. There were 23 periods of cooling and warming in the past 500 years with the average cycle being 27 years long. There were two cooling and warming periods in the past 100 years alone. 1880-1915 was a period of cooling 1915-1945 was a period of warming 1945-1977 was a period of cooling 1977-1998 was a period of warming 1998-the present, it has been cooling, all related to changes in solar activity and the Pacific El Nino and La Nina cycles

 

of the 186 billion tons of CO2 that enters into the atmosphere yearly only 3.2% is from human activity, the rest is from the oceans, volcanoes, and decaying plant matter.

 

CO2 concentrations in the atmosphere have been as much as 25 times what they are today. Current CO2 concentrations are among the lowest in the past billion years

 

Antarctica's represents 90% of the world's ice and 70% of its fresh water. Antarctica's sea ice volume was the largest ever recorded in 2008.

 

The volume of Antarctic ice in 2008 was averaging one million square kilometers more than normal. Summer ice melt was 40% below the average.

 

Solar winds are at 50 year low according to NASA, who says that the sun's output is at the lowest level ever recorded by modern instruments (announced on 9/23/2008)

 

Solar Cycle 23 which will soon be ending will be the longest solar cycle since 1796 and solar cycle 24, which is now beginning, will most likely be very weak. This is a strong indicator that the earth will be cooling and this period will last at least 30 years or more. (this is based on 250 years of observing the relationship between solar output and temperatures.)

 

Solar activity is the lowest level of the space age. There are 400 years of solar records. Whenever the sun is less active there is global cooling. There is no deviation.

 

There were three ice ages with more CO2 than today. CO2 does not have much impact on global temperatures, does not cause global warming or global cooling.

People are stupid. Why do you think our government is so screwed up? 99 % of America = retards.

I'm pretty sure Global Warming isn't just temperatures rising, but, ok.

Did they finally start teaching about global warming in your 5th grade class? That's pretty cool, since it's obvious you can't form your own opinion about it and have to rely on your teacher's.

[OSUBucksfan09]

Tru you kind of sound like you have absolutely no way to refute the evidence so you are resorting to insult him, pretty sad since his evidence completely owns global warming.

Yeah, that's pretty much what I was thinking. And when is personal opinion greater than fact?

[OldChili]

First of all, let's look at the credentials of the author of that site you linked to.

 

While not a scientists I do have a degree in History (also a minor in Political Science) from a prestigious University. Perhaps this has facilitated my ability to research the topic and also my understanding of how important it is to our society. If someone wants to know I am an automobile dealer (Pohanka Automotive Group located in Maryland and Virginia)

Sweet, he doesn't even name the "prestigious university" and he's a car dealer. Oh, so reliable.

 

And anybody can go to any random site and look up facts. I can do it too.

 

Myth: There is a huge debate among scientists about whether global warming is a real problem.

 

False. If you look at the scientific journals, you will not find anything of the sort. The consensus of almost all climate scientists is that global warming is already happening, that human actions are causing it, and that it will cause major problems for our planet. Of the hundreds of climate scientists in the world, there are only a handful who are still doubters. When the TV news gives both “sides” equal time, it is seriously misleading the public about the current state of climate science. The earth’s climate is enormously complex, so there are still plenty of research questions to keep the scientists occupied for a long time. Still, the overwhelming consensus is that we are causing a serious problem for the near and distant future. The “debate” about global warming exists only on the TV news and the op-ed pages of the newspapers.

 

Fact: There is a greenhouse effect that warms the earth, and we should be very glad about it.

 

There are several trace gases in our atmosphere, present in only minute amounts, that trap heat. The most important ones of concern here are carbon dioxide and methane. Like the glass panes of a greenhouse, they let sunlight in to warm the earth but keep some of the heat from escaping back into space. If they were not there, the average temperature of the earth would be well below freezing, and none of us would be living on it.

 

These greenhouse gases have natural sources that produce them, and natural “sinks” that remove them from the air. These natural processes have kept the greenhouse gases stable for the past 10,000 years—since the end of the last ice age. The problem now is that we are producing these gases much faster than the sinks can remove them. Our carbon dioxide comes mostly from burning fossil fuels in power plants, cars, trucks and factories, and so on, and from burning tropical forests. Methane comes from agriculture, landfills, leaking natural gas lines, and coal mines.

 

 

Myth: Solving global warming will devastate our economy.

 

Nonsense, utter nonsense. The “studies” that produce that conclusion only get those results by starting with the assumption that it will be enormously expensive because there are no substitutes for fossil fuels and there is no way to become more efficient. As Amory and Hunter Lovins say, that is an assumption masquerading as a fact, and it is “flatly contradicted by experience.” Like the old saying about computers: “garbage in, garbage out.”

First, did you read the site I linked? If you did, then you would know that the "salesman author" only cited information that came from various websites, and he gives you multiple links for the sources. Sites including nasa.org, ICECAP.us, and noaa. You can also research each of the topics that is listed, and find more claims that back it up. Its facts and numbers, not an opinion piece. The site you linked me is all listed by one author, and does not backup his claims besides his own words.

 

Here is a quote your site listed, "During the 20th century, the global average temperature of air at the surface increased by over 1o F., and much of that was due to our greenhouse gases." His reasoning is "much of that was due to our greenhouse gases"? Wow great supporting evidence, it all makes sense now

Uh, picking out one sentence out of a fairly long article out of context does not mean anything. Maybe you should have listed what he wrote before that sentence, which explained why greenhouse gases play a large role.

Care to disapprove?

No, could you post a fact about global warming that you didn't find in the top 3 results when you googled, "global warming facts"

Full quote " The earth is getting warmer—both the air at the surface of the earth and the earth’s surface itself—and it is warming much faster than any natural variation.

 

During the 20th century, the global average temperature of air at the surface increased by over 1o F., and much of that was due to our greenhouse gases. Now, this looks like a very small number, but it really is not. It is a global average and in that context it is very large. There is “only” a 9o F. difference between the middle of an ice age—with glaciers covering the northern United States—and our climate today."

 

So guy is saying earth is getting warmer, true it was for a period of time, and that there was a 9*f difference between the ice age temperatures and today? Thats pretty cool.

 

The quote you asked me to "disprove"

 

"There are several trace gases in our atmosphere, present in only minute amounts, that trap heat. The most important ones of concern here are carbon dioxide and methane. Like the glass panes of a greenhouse, they let sunlight in to warm the earth but keep some of the heat from escaping back into space.

Methane comes from agriculture, landfills, leaking natural gas lines, and coal mines."

 

True, there is several traces of gases in our atmosphere, nothing to dispute there. Greenhouse gasses does keep the earth warm, and traps some of the heat energy inside the planet, nothing to dispute there. If it was not for greenhouse gases, there would be no life on earth, I agree. Yes the earth does have natural ways to produce greenhouse gasses, agree. We are producing more co2 and greenhouse gases each year, with the population increases and more factories being built, I agree.

 

Lets look closely at his quote again

 

"Our carbon dioxide comes mostly from burning fossil fuels in power plants, cars, trucks and factories, and so on, and from burning tropical forests. Methane comes from agriculture, landfills, leaking natural gas lines, and coal mines."

 

I agree, OUR Co2 does mostly come from what was listed, HOWEVER, out of all the 186 billion tons of co2 released in the atmosphere yearly, only 3.2% is from actual human activity, the rest is from the oceans, volcanoes, and decaying plant matter. Majority of earths greenhouse gases is watervapor.

First of all, I believe your percentage is wrong. Humans, according to USGS, emit 27 billion tons of CO2 per year (estimated 130 times the amount volcanoes emit.) According to Wikipedia it's more around 28,431,741 tons. Either way, that's about 14.5%. While that may seem like a small number, compare that to the past and that's a pretty significant number.
