Global Warming?

Question

Is global warming really an issue? I know most people believe that there is no debate on the subject, but is that truely the case? Is there enough sound, reliable science to support climate change that is human induced. Serious answers please. Support your thoughts with evidence when appropriate.

Is there anybody out there, individuals like myself, who feel that the "science" or rather predictions of global warming are flimsy at best.> The earth is waming. Ture. It's occuring naturallythough and the public's misconcpetions are way off. Am I alone in my ways of thinking. I would like to hear from follows 'skeptics' if there are any. What makes people believe in global warming, anyway?

Answer 1

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 2

There is a trend of temperature increase, this is measured reality. But the relation between temperature increase and greenhouse gasses is not well established. There is no science to support a hypothesis that greenhouse gasses are the primary cause of global warming. There is no validated data to support the prediction that future temperatures will increase drastically.

The fear of global warming comes from predictions that future temperatures will increase drastically. This prediction is bases upon computer models. The models have three problems:

1 - There is no long term temperature data from the past two millenia. Accurate global temperature is available only for the past 140 years or so. Temperatures before that, used for input into computer models, are estimates based upon geographic measurements. There are no methods to validat these estimates. In other words, there is no way to know if the temperatures put into models are correct.

2 - Global climate models use mathematical formulas to predict what future temperatures might be. This is where the real fear of global warming comes from. Users of the Global Climat Models predict that, in the future, very drastic global warming will occur. The trouble with this prediction is, that even if *RANDOM* data are input for past history (see the description in 1. above), then the models predict drastic future warming. More simply, the models predict drastic future warming because the equations force it to make that prediction.

3 - *NO ONE* has any data...at all...to determine what part of current warming is caused by either greenhouse gasses, or by natural fluctuation of the sun.

From the site below: "The majority of climatologists agree that important climate processes are imperfectly accounted for by the climate models."

Answer 3

How can you say that most people think there is no debate that it's not a problem??? Do you only watch 24 hour news networks for your facts??? Global warming is not natural, the greenhouse effect is natural. Yet, due to the incredible anthropogenic (that means human caused...) increase in carbon dioxide, the planet is warming beyond natural levels. Please do not answer people's questions on global warming if you're asking questions about it yourself... That clearly diplays that you have no idea what you are talking about... Do some research, you'll find that there is a global scientific consensus that global warming/climate change is REAL and a very incredible issue that must be dealth with as soon as possible.

Answer 4

Global warming is a myth, sorry to tell you that. When satellites measure the Earth's temperature, they get the same temperature. Remember, most people only observe a small area, and say that the whole world is warming up. Also, studies show that the world was significantly hotter 200 years ago!

While we may have an especially hot summer, someone else might be having an especially cold winter. So you have to measure the whole Earth's temperature.

Lastly, while some polar ice caps are melting, others are steadily growing! (They never mention that, do they? =)

I hope this helps!

Answer 5

YES! Global warming is serious issue! With all the use of fossil fuels, it is estimated that we have used enough to account for 13,000 years of plants. CO2 emissions and CFC emissions break down the ozone layer, letting more ultraviolet B light it. IT IS A SERIOUS ISSUE

Answer 6

I am usually annoyed by people who assume a link to wikipedia is the best answer for every question on Y! Ans. but here it is actually the case.

Wikipedia gives a good, skeptical and argumentative article on this topic. It provides many views and evidence for both sides.

Answer 7

evidence!?!? Okay, look at these chemtrails, which are used to reflect the suns solar rays!! Main ingredients, barium and aluminum!
