Aww too bad, on the other hand you could just try and disprove what I just typed instead of making a remark like that which doesn't contribute to the discussion at all.Vilham wrote:

Me too. If his grasp of climatology is a good as his grasp of global economics then this is going to be a tiresome and pointless discussion.....Vilham wrote:

Major volcanic eruptions in Siberia led to the heating of the earth just enough to allow frozen methane pockets in once frozen bogs and under the ocean to be releases in to the atmosphere in a staggering amount. This led a detrimental increase in global temperatures and caused the death of 95% of life on Earth. Global warming at it's finest. The path we may or may not be heading too.dayarath wrote:
The earth is heating up but that doesn't say the global warming arguments (aka; it's our fault) are real, we've only been studying this planet's weather patterns for a very short time, 250 million years ago the earth was about 60 degrees hotter on average, and there were no cars or humans involved back then so how did that happen?
We aren't sure wether it's us or another of the earth it's cycles in temperature, all we know that it's getting hotter for a majority of unknown reasons. Everyone tries to disprove eachother, one side saying it's not and the other side it's all human faults, but it's too early to judge and we don't have sufficient information to say for sure.
So, yes I agree that the earth is getting slightly warmer but saying it's obviously our fault is bull, whilst we don't have enough to prove that.

I'm being sceptic, I don't know wether it's us or something else being the main source of contribution, I know that we do play a role I never said we didn't, but I don't think it's of that much significance if you look to certain aspects of this thing, one of them being increased solar activity and at it's peak in the past 8000 years, which can be seen here ;Vilham wrote:

Please direct me to the posts you've written in past threads that somehow should enlighten me it's all humans, because you're too much of an ass typing it here and it takes a while to find anything in a 68 page posting history.Vilham wrote:

You do realise that volcanic eruptions have a positive overall effect on climate change, slowing the rate of global warming. It's to do with ash clouds blocking out sunlight.dayarath wrote:

Volcano activity has become more the past time and no, volcanoes don't only emitt CO2 but alot more gasses which seem to be harmfull for our planet, such as water vapor , and sulfur dioxide.
http://www.geology.sdsu.edu/how_volcano … fects.htmlVolcanic eruptions can enhance global warming by adding CO2 to the atmosphere. However, a far greater amount of CO2 is contributed to the atmosphere by human activities each year than by volcanic eruptions. T.M.Gerlach (1991, American Geophysical Union) notes that human-made CO2 are dwarfed the estamated global release of CO2 from volcanoes by at least 150 times. The small amount of global warming caused by eruption-generated greenhouse gases is offset by the far greater amount of global cooling caused by eruption-generated particles in the stratosphere (the haze effect). Greenhouse warming of the earth has been particularly evident since 1980. Without the cooling influence of such eruptions as El Chichon (1982) and Mt. Pinatubo (1991), described below, greenhouse warming would have been more pronounced.

thats the thread.
Ill leave bert to destroy any points you make. Hes good at that.
With the ashes I don't know, the sun beams don't hit the ground but neither do they leave the atmosphere if the ashes are underneath that.Bertster7 wrote:

No, you don't know, clearly. But the scientists who have demonstrated that climate shifts triggered by various eruptions fit with observed climate models do know. The haze effect is quite an important factor in modelling global warming, a much greater factor than solar variation certainly - at least according to the IPCC models (which are the most definitive available).dayarath wrote:

Well the general idea of that thread is to say that humans enhance the effect already being caused by other factors which is not what I tried to disprove, I was going over the bull that it's only humans making this earth worse.Bertster7 wrote:

That other global warming thread gets interesting around page 12....

Isnt that the easy way out though? Why not just work to lower CO2 emissions anyway?dayarath wrote:

Of course it's not only caused by sources of anthropogenic origin. There is plenty of evidence that shows global warming and cooling to be cyclic. There is also plenty of evidence showing the rate of changes throughout history (vostock ice core samples and such like).dayarath wrote:

We can ofc still reduce the effect but I don't think we'll be able to stop it fully to make the global warming effect become less, we'd have to shut down about 90% of our industry to make that happen.
btw read edit above regarding the quote
