If the icecaps in the polar regions melt due to the direct effect of UV Rays, then after they become liquid water and rise the level of the oceans.After that when the UV rays make a direct impact on the water, evaporation should take place and this should result in the decrease in the ocean level ?

Your statements incorrect and/or simplistic.

But one can safely say that if the ocean levels rise as many expect ... what happens in the following decades and centuries will be of little interest to a large percentage of this planets inhabitants.

During times of high sunspot frequency the Earth warms, like now. During times of low sunspot freqency the Earth cools, like the Little Ice age and the Maunder Minimum. During times of Official "normal weather" colonial Jamestown froze to death and Europe starved.

The Earth is a moist happy paradise when warmed. The Carboniferous Period sas 60 million years of Eden. Now Eden is returning and idiots are whining.

Uncle Al,

I hope you are correct, but your view that this is entirely a natural phenomenon is now at odds with the majority of the scientific community, many of whom I would presume are more knowledgeable than you on this issue.

Hey Bozo - Mars is also warming. We've got instrumentality on the surface measuring it. Who is belching CO2 or farting methane on Mars?

Al,

Do you have any data that points to there being a correlation between Mars and Earth's global warming phenomenon once the large difference in axis tilt between the two planets has been taken into consideration?

Uncle Al wrote:
"Now Eden is returning and idiots are whining."

Absolutely correct Al. Eden is returning. Seems to me, using your euphamism. That the last inhabitants of Eden were willing to risk eternal damnation to get out of there.

If your idea of Eden is most of the earth's population displaced from their cities, jobs, resources, and homes ... bring it on.

If your idea of Eden is tropical diseases such as malaria spreading world-wide ... bring it on.

If your idea of Eden is increased frequency of devastating cat 5 hurricanes ... bring it on.

If your idea of Eden is starvation, pestillence, famine, and war ... bring it on.

You are truly made in the image of the Judeo-Christian god.

The problem with your Eden, Al, is that it wasn't a very pleasant place for raising children or building a society. Or haven't you noticed that humans didn't flourish until it was over. You might want to check the climate that corresponded with the rise of human civilization about 10,000 years ago.

Al,

Are you convinced that we have not contributed (maybe significantly) to global warming? Surely things like mass deforestation cannot go unrewarded.

Maybe it was happening anyway, and maybe we are screwed anyway, but our little contribution may be the straw that breaks the donkey's back.

Whatever the case, it surely doesn't make sense for us to be complacent about it.

Blacknad.

Would it be cheaper to move some cities and people than for us all to expend energy on trying to stop what might be an unstoppable event. I think our ability to respond to change is more important than our ability to stop change. I say that because we are not in control of natural events on earth like earthquakes or a thousand other possibilities. It's more important to expand and increase our power than to built walls and stagnate. It's better to wait until the wolf comes to the door than live in permanent fear of the event.

Scientists from Bern University have fou... 650,000 years.

The most interesting thing about the news story to me was not just the level of CO2 but rather the fact that the rise in concentration has been at an unprecented, read NOT NATURAL, rate.

What I find fascinating, given my age, is that my generation (which I believe includes Uncle Al and Rose) has been totally irresponsible squandering the planets air, water, resources, and finances.

And not one of you that are younger have the intellectual horsepower to recognize that we are going to dump this mess in your laps. What does it take to get you folks to pull your sorry bottoms out from behind the TV and away from the keyboard and to look after your own vested self-interest?

Get a copy of Neil Postman's "Amusing Ourselves to Death" and read it.

Yes, the rate of increase is indeed alarming. I think it is too late to prevent a catastrophic warming of the Earth. Countries like China and India are going to increase their CO2 output by a large amount. The only way a disaster could be prevented is if a dictator who cared about the environment ruled the entire world.


What will probably happen is that the temperature rise will cause the Arctic ice to melt (some studies predict that this will happen in 50 yuears from now). Then you get additional heating because the Arctic ice reflects a lot of solar energy back into space. Methane hydrates will start to melt leading to even more warming. Temperatures could then rise by 10 to 20 degrees C or more, turning most of the Earth into a desert wasteland, just like what happened at the time of the Permian mass extinction.

DA Morgan - pull your sorry bottoms out from behind the TV

Get a copy of Neil Postman's "Amusing Ourselves to Death" and read it.


REP: Funny you should say that, but it was precisely that book, alongside Roger Water's Album - 'Amusing Ourselves to Death' that helped influence me to get rid of TV in my house. Glad I did - I am richer for it.

Now, if I could just drag myself away from this keyboard to go out and plant some trees....


Dan, I am younger and I do know what legacy has been left to me and my children. The problem being that this present generation is even more sold on Hedonistic Ignorance than the last. We are the first proper consumer generation and we will not give it up.

In the UK every year, we produce more photography graduates than there are photography jobs in Europe. No one wants to study proper subjects and our science & engineering will soon be in crisis due to the fact that everyone at Uni is studying Golf Course Management or eagerly applying themselves to gaining degrees in Kylie Minogue.


From The (UK) Guardian 2002 - 'Maths is as unpopular as ever. A-level students are dropping it, and teacher numbers are plunging, with serious implications for industry and education.'


If it all goes belly-up, it will be because we were all too busy furiously masturbating to porn.

A couple of British palentologists have thrown the latest spanners in the works of the global warming theory.

They've found the fossised tusks of a couple of hippos and a few other tropical species in Britan.

So the present global warmings may just be a hot spike between ice ages. There have been four rrecent ice ages so number five could be coming up in ten thousand years or so.

Iv'e heard this whining about maths before now and I'll tell you the real cause.
It's because a bunch of whining maths teachers are total intelltual snobs flunking promising kids left right and centre.
Its because the structure of maths courses is totally geared, from the earliest days, to produce a very few elite mathemeticians who DO maths. Not catered to the other 99% of engineers, mechanics, builders and such to don't actually do maths but who USE maths do do engineering.
Next time one of these maths teachers goes on the whine nail him with one simple question. Do you want BETTER mathematicians or do you want MORE mathemeticians. You don't get both.

BTW. I got halfway through a diploma in photograply before bien offered a job and I worked for 20 years as an industrial photograper.

Hippo skeletons were found in Britain about 200 years ago. This is well known.

The climate scientist know about this possibility but most of them reject this possibility. The reason you had animals like lions, hippos etc. in Britain is not because temperatures were tropical. Elephants, lions, etc. in London Zoo are not dying from cold temperatures. What happened was that these animals could migrate to Britain from mainland Europe and Africa during warmer periods.

Europe today is so heavily populated that there is hardly any wildlife left. Even in Africa animals have a difficult time. Elephants need a lot of space. In South Africa wilfdlife protectors want to cull a few thousand elephants, because there are too many of them in too small an area. If nothing is done they will destroy the vegetation in that area and cause problems for other animals.

Mathematics is a language. Most modern mathematicians have become editors and teach their students editing instead of how to to use this wonderful language creatively. What happenned to the spirit of Archimedes?

And the source of your comment Johnny Boy? On what basis do you know what modern mathematicians do or do not do? How many university's math classes have you attended in the last decade?

My guess: Your comment is unsubstantiated rubbish.

Yup. good question M D Morgan. I have studied physics for many years and found that the mathematics taught by most departments of mathematics has become more and more irrelevant. It might even be spilling over intto physics: string theory?

What's wrong Johnny Boy? Can't say how many different college's and university's math classes you've attended? One? Maybe two? Or have you been thrown out of so many schools that you can actually provide a statistical sample.

Oh that's right ... statistics is a math class and you didn't take it did you. You still think there is no difference between standard deviant and standard deviation.

Thanks for the wholly uneducated commentary. We so rarely see that on the internet.
