What are the reasons that some people believe that Global Warming is not real?

Answer 1

Read the fictional book "State of Fear" by Michael Crichton for many interesting facts (ironically).

For most who doubt it, it's a mix of cynicism and lack of definitive proof. The majority of what you hear from scientists "proving" global warning are anecdotal facts. Talking about Katrina and the melting of a glacier or two. The one possible convincing fact I've seen is the correlation between CO2 in the atmosphere and global average temperature. One of the reasons to doubt it is a legitimate threat is that the temperature is only 1 or 2F more than 100 years ago, when the means of measuring temperature were not as accurate as they are now. Many temperature measurement tracking is done in urban areas, where urban sprawl can have a major impact on the heat dome around a city.

I think most of the hype is generated for political reasons. Scientists that say more research needs to be done to determine how bad it is will get more funding then the ones that say research needs to be performed if it really exists. Politicians can blame current administrations. Countries can blame each other. Smaller countries can gain while bigger countries lose in efforts to reduce emissions.

In the day of the blame game, Global Warming is a great hot button.

I may sound like someone that completely dismisses it, but actually, I believe it is happening, just not as much as what scientists will have you believe.

Answer 2

There seems to be some evidence that the earth is warming up again, although there will be big variations on this from year to year the long term average certainly has been up.

Understanding that the earth has been warming since the last 'mini ice age' during the middle ages and the facts may not be so shocking.

Of more interest is how much human activity is impacting this process. Are our choices causing this warming or not? The planet and life will continue to survive regardless of what happens - humans as a species may or maynot.

Keep in the mind that the earth's temperature is totally dynamic and we have been keeping detailed records for only the tinest fraction of 1% of the earth's history. What we do know is that there have been many periods (often lasting millions of year) when the earth was much hotter, and also much colder than it is now.

The system is far to complex for us to fully understand. All you can say it the weather is constantly changing over time, and will continue to do so.

Answer 3

It may be that as recently as 20-25 years ago, climatologists were warning of signs of global cooling that could even be a precursor to another Ice Age. The last major one was only 15,000 years ago, and there is still a lot about the global cyclical patterns that is unknown. The geological and fossil records both show evidence of periods of both warming and cooling but with periods of differing frequency. Is one cycle dependent upon another? How much temperature variation notes the difference between a "minor" and a "major" event? No argument that mankind has an impact, but is it greater than the earth's own natural rhythms? In many cases, the jury is still out.

Answer 4

climate replace isn't something new - the earth variations climate for thoroughly organic causes. some warming does no longer practice the greenhouse idea. the concept seems speculative in significant options. The outcome of CO2 is quite small - climatologists predict lots of the warming will come from effective feedbacks - there is a few warfare of words on what the effective feedbacks will be. the international warming predictions do not look a sturdy more effective healthful with authentic international information. The globe is warming at about an identical fee now that it change into 80 years in the past even in spite of the undeniable fact that CO2 ranges have replaced appreciably in that aspect.

Answer 5

I'll tell you why I have doubts. We know that over the last few thousand years similar temperature changes have happened. We know this from ice core samples, archaeological data, sediment samples and several other sources. None of these events coincided with meteor strikes or volcanic activity. Sometimes natural events occur that cause quick changes on the Earth.

The second reason is that I have several knowledgeable friends and most of them believe the changes are not caused by human activity. They work for the national weather service and have advanced degrees in meteorology.

I do support most of the things that gloom and doomers think would slow down, stop or reduce climate change. Solar and wind power is great. Dependence on foreign oil is bad. Oil and coal are dirty and unpleasant. Going green is good for the economy and the country as a whole.

Answer 6

CO2, the magic molecule. It allows the sun's solar radiation to pass through to the earth's surface, but it does not allow that same radiation to reflect back into outer space.

Global warming is like the deficit- you can worry about it or not worry about it. It doesn't really make any difference to anything.

Answer 7

Possibly inconsistent weather patterns.

Answer 8

1 reason is that the earth has been through cooling periods,and also heating periods.Its not abnormal really.

Answer 9

Because its -20 here.

Answer 10

Ignorance and denial.
