why do some people not believe in global warming?

Question

if u look at earths graphs of co2 levels and temp levels, they follow eachother. i hear some people say co2 is not a greenhouse gas. but if that is true, then why does venus have hotter weather than mercury, then though mercury is a lot closer. i dont see their reasons why dont think it exist. why?

PS!! dont be dumb and say "global warming ahhh its dumb! it never happened!" you are just being stupid and illogical. that was not the question. if u feel u must put that, i question your intelligence. give me REASONS why u dont believe it. not some rant.

what curly said was a perfect example of what i dont want.. good job there curly. no where in my question does it ask about your school background..lol now your part one. ok yes, good. but u went down hill. let me ask agian. please tell me what r your reasons to believing that global warming doesnt exist. being smart is school does not disprove global warming.

) its a political issue. There is a TON of money and power at stake. With those kinds of stakes true science goes out the window.

Answer 1

From one of those "old people", In the late 70's, I worked outside in eastern Kansas and we had a couple of very cold winters. We had blizzards, several heavy snow storms and many days of temperatures below zero. According to the newspapers it was the coldest years in Kansas history. The national newspapers had headlines such as "No End In Sight For Global Cooling" and predictions of an impending "Ice Age". Now since the CO2 had been increasing from the industrial age for several decades, shouldn't it have been getting warmer? Oh, we also had used up all of our natural resources and we were in an "oil crisis" as well.
The media thrives on global crisis and scientists receive a lot of federal funding when people are afraid of natural events that they study and report on. Wait a few years, things will cool back down and we will have a new crisis.

Watch "The Great Global Warming Swindle" (73 min.) on Google video and see for yourself what those top tier scientists have to say. The scientists credentials are shown in the documentary.

Truthwillnotbesilenced - please read the 5th paragraph and what follows.

Some are just people who believe everything is a conspiracy.

Others are conservatives who just believe that anything said by liberals, environmentalists, or, worst, Al Gore, must be wrong. Some will change as rock solid conservatives are starting to understand global warming:

"Former House Speaker Newt Gingrich challenged fellow conservatives Tuesday to stop resisting scientific evidence of global warming"

If you accept global warming, you accept that things must change. Humans are notorious for denying reality rather than accept change.

I hope truthwillnotbesilenced is reading this:

"Besides, in terms of the hundred thousand year cycles, the temps rose first, then the CO2 levels went up."

You're right. In previous warmings natural causes caused warming, and hundreds of years later CO2 spiked as it was released from warming oceans. This time CO2 and warming are going up together. It's one of the proofs you want that this warming is not natural.

"Also Venus' atmosphere is 98% CO2 and stronger greenhouse gases. Ours is a hundredth of a percent. And Venus while obviously uninhabitable is about 14 times as hot. So, about a hundred thousand times more greenhouse gases gets you 14 times as hot - - there are clearly diminishing returns pretty early on - - that would seem to mean that you can't infer that an increase of 1/11,000th of the atmosphere is going to be material"

It's not an inference, it's an engineering calculation. The system is "non-linear" (because of the physics) and the initial increment of CO2 is much more effective in creating warming . I'm not trying to be insulting, but this is a good example of a case where you have to believe scientists are ignorant about Venus or stupid to not have figured this out.

The science on global warming is rock solid. Which is why the vast majority of scientists believe it's real and mostly caused by us.

Answer 3

The graphs that follow each other. What they show is co2 lagging temperature. ie. temperature raises co2 raises, temperatures fall co2 falls. This is not in dispute. All sides accept this fact.

Co2 is a greenhouse gas, but a minor one. Water vapour is the major greenhouse gas accounting for 95%. The human portion of co2 in the atmosphere is 1/3 or 1%.

A study released by Solinka et all in 2005 shows that solar activity is actually unprecedented for the last 11,000 years. So the question is it the sun or co2 that is causing the current warming. More and more scientists and the body of empirical evidence show the sun as the cause of the current warming.

In the site bellow look at the correlation between sun spots and temperatures and co2 and temperatures. http://www.geocraft.com/WVFossils/Reference_Docs/The_Geologic_Record_and_Climate_Change.pdf

The more sun spots there are, the more solar flares the sun emits. Solar flares cause huge increases of irradiance in every wavelength in the spectrum. Some of the material ejected from solar flares is super heated gas from below the sun's surface. Much of this gas is deflected by the Earth's atmosphere. Satellites measuring energy from the sun do not detect this portion of heat from the sun because it is not radiative energy.

The earth is also being constantly bombarded with cosmic rays. When these cosmic rays hit the earth's atmosphere they interact with the water vapour in the atmosphere and form clouds. These clouds deflect the heat of the sun cooling the earth. (The effect was also recreated in the laboratory by Henrik Svensmark, who is Director of the Sun-Climate Center within the Danish National Space Center in Copenhagen.) Solar flares, which are like solar wind blow these cosmic rays away from the earth resulting in less cosmic rays hitting the earth, less clouds forming and more of the sun's energy hitting the earth warming it up.

Answer 4

Bebop they follow each other in periods of 100s of 1000s of years - in terms of multi-century trends they do not.

It's been warmer than it is today for other multi-century periods since the last Ice Age, we don't know the full reason why, but we do know that CO2 levels were lower.

That doesn't disprove AGW.

It does mean you can't just infer it from the present correlation.

And it's your burden of proof to show that the activities you want to limit cause the harm in question, not mine to justify doing what I want to do.

Besides, in terms of the hundred thousand year cycles, the temps rose first, then the CO2 levels went up.

Also Venus' atmosphere is 98% CO2 and stronger greenhouse gases. Ours is a hundredth of a percent. And Venus while obviously uninhabitable is about 14 times as hot. So, about a hundred thousand times more greenhouse gases gets you 14 times as hot - - there are clearly diminishing returns pretty early on - - that would seem to mean that you can't infer that an increase of 1/11,000th of the atmosphere is going to be material - it might be but you can't infer that, and that inference is what you've got.

Answer 5

Your first sentence is a lie. When you look at a graph of human produced carbon dioxide and a graph of the temps they are not correlated, dumbass. When there was this thing called the Great Depression, human produced carbon dioxide fell dramatically. You think the earth started cooling down or warming up slower? It didn't. So you have been fed lies are are to stupid to question it. Why is mars warming at the same pace we are? Humans only produce about 3% of emited carbon dioxide. Why can't you think for yourself instead of beleiving whole-heartedly in abstract theories? Are you a sheep? The world may be warming but who is causing it? is the question and that question is by no means answered. So your beleiving what they tell you to believe. You are a sheep.

Answer 6

their minds are too small. They believe that if the weather in their little piece of the world is just fine, then the rest of the world is just having a little storm, or two. The trouble with Global Warming is not that it may or may not be caused by humans. The real problem with Global Warming is that it may be too late to do anything major to mitigate it. There might already be way too many people on the Earth, and the only way to really make an impact would be to either reduce our numbers by one third, or reduce our standard of living by one third, or more. Or both. Too scary for most Americans to contemplate...

Answer 7

96% percent of greenhouse gases don't come from human beings, they come from the earth itself.

This isn't the hottest the earth has ever been, it's the hottest on record. (accurate records didn't start until 1860)

Climate patterns change naturally, and the earth as a whole is still on something of an upswing from the last cold spell which occured around the 16th century.

It takes hundreds of years for the earth's atmoshperic composition to change, so if we stopped producing greenhouse gases we would see about a four percent change in about 3 to 4 hundred years.

keep in mind that the amount of greenhouse gases released in a massive volcanic eruption is hundreds of times greater than anything human beings have ever been capable of releasing.

Personally it seems to me that global warming might have some credence, but the far bigger issue is that we are gonna run out of oil long before we melt our ice caps.

I think the whole thing is a political scare tactic.

It's the democratic way to scare you into voting for them, just like so many republicans use terrorism to scare you into voting for them.

It's all rediculous, and there really isnt anything you can do about it.

Answer 8

in the beginning, international Warming isn't international warming. i've got self belief in international warming...that the earth is in a warming type. it relatively is user-friendly. (in spite of the incontrovertible fact that the severity of the warming is being oversold via activists.) however the earth warming would not start to coach all of world Warming alarmists' claims. in accordance to organic technological expertise the earth is often the two warming or cooling. in accordance to organic technological expertise (on which international Warming supposedly bases its authority) Europe replaced into coated in Ice interior the semi-modern previous. This ice melted long until now any of the meant reasons of world Warming existed. How? Mars is likewise experiencing planatary warming. How? guy isn't there polluting something. as far as greenhouse gases bypass...the mere coexistence of phenomena would not point out causality. And suitable to a theory in international Warming is a static view of the earth's environment. The organic international isn't static. i'm open to theory in international Warming, however the data isn't there. Why?

Answer 9

I don't think it's so much that they don't believe, I think they just don't care because they think someone will take care of it. or they just don't believe because it's too much for them to handle. They probably think if they leave it alone that it will right itself. cuz really if you think about it, there is proof and there is no way to argue the fact that we are going though it. So it's not that they don't believe (as much as they insist on it) it’s that it’s easier for them to say they don’t.

I know this isn’t part of the question but I feel it is, just a bit.
The reason why we are going though global warming is because human kind (yes us) have been taking advantage and being lazy. Think about it… people use to ride horses and walk to their destination but now we have cars because we don’t want to deal with horse **** and hay. We have washing-machines when we as humans washed cloths by hand… we have been very lazy and in turn created theology without consideration on how it would affect the planet. And again we are being lazy by not correcting our mistakes because that would mean we would have to reinvent everything (which to me seems very interesting and fun and a way to improve.. you never know we may be in eco-friendly flying cars if they try hard enough.)

Answer 10

1) its a political issue. There is a TON of money and power at stake. With those kinds of stakes true science goes out the window.

2) you cant have it both ways. You can either ask a genuine question hoping for a real answer, or you can insult answerers and call them stupid. You cant ask, then call me stupid, then expect a genuine answer.

3) question my intelligence, Im mensa qualified, at the top of my class and about to graduate college with a bachelors of science in engineering. I tested out at a second year college level when I was in 8th grade. If you can question my inteligence, then I can question yours. What makes you anything more than a mouthpiece for political propaganda?
