Just a couple of questions. Can you please provide a source from a scientific journal for the point I have bolded in the above quote. Its not a view i've seen published before and i'm interested to see where exactly its come from.
Volcanoes are very effective at changing the climate in a number of ways. They are very effective at dispersing fine dust over 15 kilometres into the atmosphere, which has the potential to cool it, along with releasing Sulphur Dioxide during an eruption, which causes atmospheric cooling. Look at the climate records which have been posted in this topic fairly early on in the discussion and notice the change after 1991 for the following 2 years. This has been attributed in part to the eruption of Mt Pinatubo in the Philippines.
Going even further back in time its believed the eruption of the Deccan Traps (an 8 million year long eruption between 68 to 60 million years ago) caused a significant change in the global climate leading to widespread species extinctions as the temperature cooled globally by over 2oC, a major change.
Global warming I can assure you is not media hype. Even if the world doesn't end soon, basically the way we are living life and conducting business now is unsustainable as many sources of fuel we use for energy and to power our economies are finite. If we act now and make changes to the way we live life it may just save us from having the entire globe coming to a shuddering halt and prevent pandemonium from breaking out.
You can ask all the questions you like,but you only get one answer,and that's about the part you Bolded.
Go back and read what I said there properly. |  | |

Yep, clearly stated, movie, and laughable, irrelevant, not unlike a lot of the hysteria.
GW is a fact, the dispute is about whether humanity affects it, it's that simple, and useless. It's going to happen, rather than argue about how or how much, we should be getting ready to deal with the effects. If we have and are contributing to it by what we do, then we're up the proverbial creek without a paddle, no-one can stop that.  |  | |

Tree huggers need to consider three questions.
1) If Earth is too warm, how much would you decrease the temperature?
2) How would you decide on a temperature?
3) Other than eliminating fossil fuels, how would you decrease the temperature?
1) Earth has a self-regulating temperature. Once sources of carbon dioxide pollution were eradicated, the temperature would fall back to pre-industrial levels because of natural carbon sinks like vegetation. If sufficient natural carbon sinks no longer exist, we could make our own, eg. oceanic algae or nanomachines.
2) The average temperature of Earth's atmosphere just before the industrial revolution would be appropriate. These are the temperatures to which most life on Earth is adapted. Keep in mind that the specific temperature is not fundamentally important, it is the rate at which the temperature changes which has a destabilising effect, causing extreme weather conditions and rendering certain habitats sterile and unable to sustain human populations.
3) See 1).

I had a link to another site,it had a thing called Home Planet Earth,I just wish I could find it again to post.
It's a 790 meg download so not for those with a short attention span,but does show how we've contributed,and it's only us Industialised Country's that have done it. | | | | Edited: November 12, 2009 @ 14:03 | |

surely you can not be right when you say it is only us industrialised countries that have done it? Industrialised countries yes have contributed the most, but developing countries also play a role. Solving this problem is going to take a worldwide effort and that is something which governments still disagree on. They are trying to protect their own interests first before the worlds. Its a shame really.

There is no dispute.
Since humanity began tapping into Earth's vast fossil fuel reserves and converting them into atmospheric carbon dioxide as a by-product of combustion, atmospheric carbon dioxide levels and global average temperature have climbed more rapidly than at any other time in geological history. This single most dramatic warming event in the history of Earth cannot coincide exactly with human industrialisation by chance. The observations are there, and we have the science to explain them; carbon dioxide traps heat in the atmosphere. There is no dispute anymore, except the minor grumblings of people who can't be bothered to change or have a monetary interest in prolonging the controversy.

You're preaching to the converted here Billyboy, I completely agree.
But my view is that we won't be able to stop the pollution, that's called "realpolitik", and we won't convince the skeptics either, so lets not bother trying, it's probably a good time just to be heading for the hills!
