Well, frozen iceball. But unfortunately the Sun isn't warm enough. Without the effect of so-called greenhouse gases reflecting back outgoing radiation, we'd be about 30c colder.
An inconvenient truth?

Ok... and so does that disprove my point?
I am not talking about Al Gore... im talking about Martin Durkin. If you have nothing to say about that, then fine. By don’t try and deflect it onto another argument.
I know what i believe... and like i said before, we can all keep throwing around statistic, web links, quotes from scientist etc... but very few people actually truly understand the environment or climate change. We all smugly using/quoting second hand knowledge, as if it was our own. I am honest enough to admit that my belief in climate change and the damage, i believe, we are doing to our planet is a leap of faith.
I will now politely withdraw from this thread because it is a discussion i have been involved in many times and, to be honest, i find it tiresome and stressful.

oh, and I suppose Al Gore had all the answers too?
Guess not.

Your right, it is hard to determine exaclty what is going on. I respect you for your belief. All I do have to work on is others whom I put my faith in like Alex Jones. If only I was a scientist lol

As for Al Gore being wrong... there were only 9 statements he made in his entire film that are truly under question, and even then they're quite minor and exhibited a poor choice in words/examples that could have been easily demonstrated another way.
Those, by no means, invalidate any of his points. He actually had the VAST majority of his facts straight, and the current anthropogenic warming is already having devastating environmental, agricultural, social, and economic consequences:

A British judge did rule that there were 9 inaccuracies in his scary movie. If you wanted to really pick at it, you could find much more though. 35 Inconvenient Truths. But then again, that's according to one of those 'right wing, oil funded, kooks and liers' associations
But seriously, if Al Gore wasn't profiting so much now, I'd almost think that he was trying to include many flaws in his movie.
How do you know that AGW is having devastating effects? Because the climate has always changed, and will continue to do so, whether we emit CO2 or not. But it seems every disaster now must be due to AGW, ignoring that these events have always occurred in the past.
Take for instance, the alarmists claims of islands being inundated, due to AGW. When are they going to realise that many of these islands, such as the Carteret Islands, are sinking, which has nothing to do with climate change. It is common knowledge that atolls are formed due to ancient islands slowly sinking. This is a well known fact, yet alarmists still try to blame it on AGW, even though there has been no detectable acceleration in sea level rise. There is also the fact that many islanders have used dynamite, and blown away sections of the reef, leaving them more exposed to wave and tidal action.
Also, the often used poster for AGW (at least since the polar bear has been shown to be doing fine) is glacier melts. What many don't realise is that glaciers are poor indicators for present climate. Some glaciers have long and complex reaction times to things such as temperature, precipitation, wind and ocean currents. Sometimes up to hundreds of years, especially for larger ones. Although many are receding, some are also growing. But this is certainly not proof of AGW.
So although Al may have got some of it right, his Hollywood drama was always intended to pull on your emotions and feelings, regardless of the science. At least it helped kick start his carbon trading business.
But it's only oil companies that are corrupt, right?

Yes actually, you're correct- you picked a terrible source for "35" inaccuracies in An Inconvenient Truth.
In 2005, the people of the Carteret atoll in Papua New Guinea announced their imminent evacuation. See this article for more details. According to this Greenpeace blog, the evacuation is due to begin in 2008.
Historically, global warming events at the end of ice ages have not been triggered by rises in atmospheric CO2 concentrations. However, as explained in Climate myths: Ice cores show CO2 increases lag behind temperature rises, disproving the link to global warming, this does not disprove that CO2 warms the atmosphere and that rising CO2 emissions have cause warming since the 20th century.
Cullen's team came to the conclusion that "rather than changes in 20th century climate being responsible for their demise, glaciers on Kilimanjaro appear to be remnants of a past climate that was once able to sustain them".

It's simple math really- there are certain gases which contribute to a greenhouse effect on our planet; we have emitted an immense amount of them that has lingered in the atmosphere over the past century; this has created a rapid/upwards warming trend in global averages temperatures.
no matter what this WILL have effects on various ecosystems; glaciers/ice caps are diminishing in volume; desertification, drought, flooding, and sea levels are increasing; causing such an abrupt change in already-weakened global ecosystems is a DANGEROUS thing. Must I really spell it out for you?

I don't know where you're getting "every disaster now must be due to AGW"
As for these events "always" occurring in the past... the reality is the rate/severity of global weather patterns is abnormal when compared to the past, so it IS different..
Formation of Atolls
An atoll is thought to begin as living corals colonize and build a fringing reef on the flanks of a seamount or volcano. Over time, as the volcano cools and becomes denser, its gradually sinks below the sea surface. The corals, whose symbiotic algae require light to grow, continue to build the reef upward towards the sea surface, maintaining the top of the reef in the photic zone. The reef gradually becomes separated from the subsiding island by a lagoon, thus forming a barrier reef. Eventually the cold volcano sinks so far that it disappears beneath the surface, leaving behind the characteristic ring-shaped reef surrounding a central lagoon
source
A computer analysis of tide-gage records in the northeast Pacific indicates that the active volcanic islands of eastern Hawaii are subsiding at a rate considerably faster than the eustatic rise of sea level. The rate of absolute subsidence increases progressively toward the center of current activity on the Island of Hawaii. Honolulu, Oahu, appears to be stable; Kahului, Maui, is subsiding at 1.7 mm per year; and Hilo, Hawaii, is subsiding at 4.8 mm per year.
