i think it is genuine, they said its 1st time the whole of uk's been under snow for 50odd years, but im still REALLY scared of global warming
+ did anyone hear the bbc propaganda machine in full flow tday, saying how scotland was almost as cold as the south pole last nite, so what, the southern hemisphere is in the middle of summer at the moment, so if it is that cold then thats brilliant because it means the ice wont be melting, the comparisons they should be making is with the north pole which as scotland obviously lies in the northern hemisphere, but im sure it would have made their agenda look pathetic
I dont get hows that propaganda really man, surely its just an interesting fact that we're as cold as the south pole. The summer season in the lasting only 2 months anyway i think, December and January right.
In regards to Global warming, the InterGovenal Panel on Climate Change 2007 concluded that there is a 90% chance of the change in climate originating from human causation. In 2009 the Global Change reform conclude that it was ' unequivocal.' In regards to the increase of temperature directly associated to human activity, this is taken from a longitudinal study spanning 50 years. The 2004 Aritic Imapact Assessment conclude results mirroring the previous.

All advise countries to start to lower emissions to help prevent the rise in globel temperature.
It hasnt warmed since 1998 is a usual criticism used, however as explained in much better terms than i ever could this is a misleading statement
Imagine you’re trying to detect warming or cooling where you live in the Northern Hemisphere. You leave your thermometer outside in the shade and you run out at 3pm to read it. Then you run out every hour afterwards until you go to bed at midnight. Unbelievably the temperature is going down! Global warming must be over!
Obviously this is because you’re going from day to night; a natural cycle that doesn’t contain useful information about underlying warming or cooling. Fortunately, there are two simple ways to get around this.
Only compare like-with-like, eg compare midday one day with midday the next.
Use a ‘running mean like a 24 hour average.
I’m going to concentrate on 2) because it accounts for the changing amplitude of the cycle (eg a day with clear skies will have a warmer day/cooler night than a day with cloudy skies, comparing midday with midday wouldn’t work as well).
So you keep measuring the temperature day after day, starting in July and by December you’re really confused. It looks like you’re cooling. Global warming must be wrong again!
Obviously not; you’re in the Northern Hemisphere so you’re going into winter. Another pesky natural cycle has ruined your trend. So repeat 2), average over 12 months and you can compare years.
It’s ridiculous to compare night with day, or summer with winter; so why do some people compare an El Nino year with a La Nina year? Or a strong El Nino with a weak El Nino (this is like comparing midday with clouds to midday without clouds). You can’t extract any useful information about trends from this data!
Once you count for the El Nino and solar cycles then you can see that something with a period longer than 10 years (and from that graph, longer than 60 years) is warming us. The rest of this site shows a lot of the evidence as to why scientists believe this effect is greenhouse gases, rather than anything else.
This is a summerized version of the argument, however it sums up the main points i think, please refer to graphs here.

The most quoted study for those who do not believe in Global warming is Usokin 2005, however again this study is mis-interpretated, again i turn to sources much more qualified to discuss this i am
However, a crucial finding of the study was the correlation between solar activity and temperature ended around 1975. At that point, temperatures rose while solar activity stayed level. This led them to conclude "during these last 30 years the solar total irradiance, solar UV irradiance and cosmic ray flux has not shown any significant secular trend, so that at least this most recent warming episode must have another source."
In other words, the study most quoted by skeptics actually concluded the sun can't be causing global warming. The evidence that establishes the sun's close correlation with the Earth's temperature in the past also establishes its blamelessness for global warming today.
Furthermore is the argument that Climate Change occurred before we as humans had the capicity to change the climate so to speak however
Natural climate change in the past proves that climate is sensitive to an energy imbalance. If the planet accumulates heat, global temperatures will go up. Currently, CO2 is imposing an energy imbalance due to the enhanced greenhouse effect. Past climate change actually provides evidence for our climate's sensitivity to CO2.
Results to this end has been proven by various experiments from satillites and surface measurements. Please see source for this.

Finally the petition project produced 31,000 scientists who challenge human causation of Global warming, That humans are causing global warming is the position of the Academies of Science from 19 countries plus many scientific organisations that study climate science. More specifically, 97% of climate scientists actively publishing climate papers endorse the consensus position.
In addition the number of scientists who reply yes to the causation of Global Warming being human increases as the level of expertise in the field of climate science increases. Doran 2009 posed the question Do you think human activity is a significant contributing factor in changing mean global temperatures? 90% of participants had PHD's, 7 % Masters, 82% answered yes. Of those scientists who were non climatologists 77% yes, but those scientists who were Climatologists and were actively publishing 97.5% answered yes.
I will have to apologise as science is my field really, my qualifications are either poltical or theology based. But the last point is my real reason for believing in the human cause of global warming, those who know much better informed and able to grasp the concept of science infintatly better than i could ever acheive have a consenus that it is the truth, i being a believer in Evolution, would have to believe this as it is in fact a higher consenus than that which relates to evolution in many respects.
