You guys dont get global warming..

As the ozone layer gets destroyed by us idiots heat energy from the sun ges further into the Earth.

At night radioational cooling occurs more rapidly(colder nights hotter days)

It can be 100 degrees in the afternoon
at night it can be -100

Bloody cold as owt over here. I can't wait till I go back home down South for Christmas.

Well it does not take much to get your own idea of global warming. Here are two lists of temperature anomalies, load them into Matlab or Octave and plot them out.

When doing it though be careful as you should probably exclude all data prior to 1960, as the accuracy of temperature readings from the time before satellites was not that great.

The real problem is that this does not tell you much. We have a small time sample, and out understanding of global climate is immature at best making just applying a linear trend to this may not be the best method. You will see a lot of models posted by climate researchers out there but they are hard to trust as what sort of regularization was done in their models is never mentioned. The combination of those things makes predictions on global warming I think pointless. On the other hand the basic point that CO2, CH4, and water vapor block the transmission of long period light back to space does help to support the idea that there is something going on with the a rise in global temperature.

eughh, okay I have to begin by saying the Ozone has nothing to do at all with global warming, ozone absorbs ultra violet light, heat is caused by near infrared light

The depletion of ozone by cfc's (which we have stopped producing by the way and descarded objects with cfcs are carefully cleaned and contained at least in the US) has nothing to do with the recent warming trends

and radioational cooling, uhh that's not a word or phrase I've ever heard of

When I was a child living in the South France moving away to Belgium I know that it was the first time that i saw snow but the last ten years I don't see many snow anymore (but a lot lot lot of rain X_X).

Empirically, the fact that the planet is getting warmer is pretty hard to deny at this point. Scientific evidence of that is almost indisputable. Most of the debate is over whether this is mankind's fault or not.

If you doubt that the planet is warming, just follow the money. Canada, Russia, the US and Denmark are all scrambling to claim their share of the northwest passage and potential arctic resources, while the ski industry in Europe is in a panic because the Alps seem to be warming twice as fast as the rest of the planet.

The biggest concern with global warming isn't the incremental temperature increase or even the increased frequency of extreme weather. The biggest threat is that certain systems which we take for granted may be seriously disrupted. Reduced snowfall in mountainous regions means reduced fresh water in most river systems, jeopardizing the water supply of millions of people. Melting ice caps could threaten the Atlantic Conveyor, which would plunge western Europe into a Siberian climate.

These are worst-case scenarios, it's true. But these catastrophes far outstrip the threat of rogue states gaining access to nuclear weapons, which have been used to justify military campaigns costing many billions of dollars. Surely we could afford to spend a few billion to try to head off this disaster, or at least slow it down while we get a better understanding.

The blog has moved, but if you want a nice, referenced, complete digest on the science behind anthropogenic (man-made) global warming, this guide is comprehensive and easy to understand:
