the question is to what extent are mans actions contributing to it? i believe in global warming, it would happen if there weren't any people here ( it might just take longer ) other planets in our solar system are also warming up ... we've got to learn to adapt to the changing climate, and we're not.
on the subject of global warming ( and the media )
| Quote: | Max Boykoff and J. Timmons Roberts of Oxford's Environmental Change Institute in a 2007 UNDP report:
“One could summarize ... that the media has at times kept the issue of climate change alive, but has also limited the extent to which real change in the organization of society [has] been called for. To put it plainly, the press has been quite reformist in its portrayal of the needed action on climate change, when the scientific projections suggest the issue may call for truly revolutionary changes. The difficult position of the media in capitalist society is that commercial news outlets require huge amounts of advertising to pay their salaries and other expenses, and the greatest advertisers are for automobiles, real estate, airlines, fast food, and home furnishings. To create demand for real mitigation of climate change emissions would require the media to repeatedly and insistently call for truly revolutionary changes in society, precisely away from consumption of the products of their advertisers.” |

I totally agree luke. Climate changes have happened before us and have happened during our lifetimes. We adapted and lived through an ice-age and more. We have obviously contributed to the current changes in climate (speeding it up) but it would have happened without us as well. Like you said, we have to learn to adapt. You think it would be something we would figure out as species we have done it more than once. |

| I wonder how long polar bears took to develop? That should be a fair indicator of how regular this happens. |

Actually glaciers are much better at telling this. That is why they study them so closely. They are our most sensitive indicators to climate change.
As for the polar bear, I found this:
"The bear family, ursidae, is believed to have split off from other carnivorans about 38 million years ago. The ursinae subfamily originated approximately 4.2 million years ago. According to both fossil and DNA evidence, the polar bear diverged from the brown bear, Ursus arctos, roughly 200 thousand years ago. The oldest known polar bear fossil is less than 100 thousand years old. Fossils show that between 10 and 20 thousand years ago, the polar bear's molar teeth changed significantly from those of the brown bear. Polar bears are thought to have diverged from a population of brown bears that became isolated during a period of glaciation in the Pleistocene.[12]"
So they came about during the last ice age. In the history of the earth, like a lot of larger mammals (including us) they haven't been around that long. |

| the last ice age ended about 10000 years ago though - not 200000 |

Of course Global Warming is just a scam dreamt up by politicians to tax us more - the North Pole melting is just perfectly normal...

Actually, the global temperature figures nows shows climate COOLING, which is why the never-wrong governments now talk of "climate change" (not climate warming), thus continuing the tax scam. Hard to get people to pay for taxes against "heating" when the world around them is cooling.

logically that makes no sense - so I did a bit of searching myself and found this link which suggests a massive volcanic eruption undersea in the area. But this doesn't explain why things have been getting worse over years.

The Pleistocene is the last ice age and lasted from 1.8 million to 10,000 years BP. So they would have evolved during that time frame. |

Yeah, I didn't really think that through properly, my point was meant to be about how you said that humans had dealt with such eventualities before and that doesn't seem to be the case. |

But we have. We lived during an ice age. The Clovis Hunters (which Clovis, New Mexico is named after) lived about 11,500 years ago and survived not only the ice age but also the climate changes that happened during that time. So our species was around during the time of major climate changes to the earth. |

but none of those changes were as intense as this current one, that's the important difference. I wish I could remember where I left the clip from a documentary that shows how this works.
I'll find it again and post it tomorrow with any luck... |

i think you've all got it wrong. the increase in temperature is due to the decrease in the number of .... pirates!
