Global warming theory?

I call it, "non-science" (nonsense).

Global warming is really a very big issue. I think by changing little bit habits from our daily routine we can save the environment. The main cause of global warming is harmful gases like carbon, methane, etc. So we should try to use these gases less. When I was a student I thought how can I help combat global warming? Then my brother suggested to me https://www.wales247.co.uk/how-can-students-help-combat-global-warming, where I can get a lot more information about global warming, and also the way which I can do to save over earth from global warming.

What we're seeing now fits no natural pattern. Claiming that warming/cooling is natural is a great argument if the data matched.

MAJ (Join to see) That we know of!

Jean, I don't see how scientist accurately collects the data and form their opinion has any political aspiration. I believe scientist is warning the law maker so they can make law governing excessive pollution which has alter the climate. Any REAL scientist would look at the data and accept it's conclusion. I took a course from Central Washington University in Oceanography and Climate. I can assure you the data is irrefutable about the changes in the Earth's climate.

Everybody is entitled to his/her own opinion about this. Even the scientists disagree.

WE WERE TOLD THAT ELIMINATING CFCs WOULD ELIMINATE THE HOLE IN THE OZONE and we needed to do that because cancers caused by increased radiation coming through the hole would be one of the leading causes of death worldwide by, IIRC, 2010. Specifically, they would be cancers that started out as skin cancer. Many countries have all be eliminated CFCs and the hole hasn't gone away. In face, now there seems to be one over the arctic. And deaths from cancer that started as skin cancer are not now a leading cause of death worldwide.
What it really boils down to is that the panic mongers that KNOW what they are talking about are pretty much full of shit.
They scream and holler and are proven wrong again and again and again.
If they would even say "with the current level of understanding we have, this appears to be what is happening" but no, they claim to have a complete and irrefutable understanding and knowledge and anyone that questions them is a freakin' idiot.
The fact that they themselves are wrong consistently while claiming to have a god-like mastery of the "science" kind of makes them look like the idiots to me.

MAJ (Join to see) we DO have increases. The hole has varied in size from 13.8 Kilometers to 29.6 Kilometers over the last 25 years, with not a lot of discernable pattern, other than that most smaller hole years are followed by a larger hole year and vice-versa. The one overlaying pattern is that it continues an overall rise in size over the period of years that we have been CFC free....By that, I mean as CFC free as we can be without banning volcanoes.

CFCs last for a long time in the atmosphere. Look at the data - the hole is half what it was in the 70s when we first saw the problem and the trend is reduction and stabilization.

MAJ (Join to see) Where is that data? I'm trying to keep an open mind, Sir, but NASA's data shows the hole to be approximately 22 times what it was in 1979 now, and just a few years ago (2006) it was nearly 27 times the size it was in 1979. While I am more than willing to consider other sources, I have to also consider that few other sources (or none) will have the extra-terrestrial view or access to technology that NASA does. It should be noted also that the "hole" isn't exactly a hole. It's more like a thin area. Ozone density is measured in DU (dobson units) and the baseline is 300 DU, for what the ozone "should" be. The DU measurement of the hole essentially follows (not exactly) the same pattern as the diameter of the hole....however, "Not Exactly" is a key factor. It did fall from 1979 to 1991, and then rise a bit, but some of the lowest points have been in the last few years (95.0 in 2011 compared to 101.0 the year before and 118.0 the year after). One additional point is that one of the top 4 things that destroys ozone is Nitrogen...yep, that Nitrogen. The gas that makes up 78.09% of our atmosphere.
As a side note, and by way of comparison CO2, the "culprit" du juor in the latest crisis, ideally makes up 0.039% of the atmosphere, which means that current levels of CO2 (0.03952%) at worst, are .00052% above ideal.
