Arctic ice melting faster than predicted!

No, not really.

 

Osama and nuclear catastrophe are the headlines now...

 

And once again, by compromising their best guesses, to make sure not to leave the doubters any avenue for criticism, they have underestimated the extent of the issue.

 

When the other planets' temperature trends begin to steadily and statistically significantly diverge from our trend, I'll worry about it.

 

Somebody just needs to go to that silly ol' ice and explain to it that Climate Change is a hoax. That will stop it from melting.

 

Hey I thought I saw that inconvient movie was predicting 20 rise in sea levels. There were lots of scary fake estimates. If you are refering to IPCC underestimating, I take most of their predictions with a huge grain of salt. I still think church's estimate of 0.5 meter or less is the likely scenario.. Remember these news reports are statistical. One will say omg its rising really fast, then the next says its not rising at all. Let's wait until we get a 0.1 meter rise before we think that the 0.59 prediction was way underestimated.

 

hoax? Liberal media propaganda!

 

Denialists prefer a strident tone. I suggest we send them all to the artic so that they can scream in unison at the ice: STOP MELTING! They can return as soon as they get results.

 

Are people not aware of global warming? I thought the argument was whether this is normal temperature change or a man made issue. Hmmmmmm.

 

actually more then few insist "there is no global warming". many of them also insist that there is no evolution and Darwin must be dug out and burned at stake.

 

maybe you should; read about Permian extinction.

When the oceanic currents stopped ocean bottom warmed up above 18C (Methane clathrate melting point) and caused massive Methane belch on a planetary scale. Since methane is ~90 times more potent green gas then CO2, it resulted in another warming/die out, with ~96% of all sea life and 70% terrestrial life extinct.

For comparison Cretaceous–Tertiary event which killed dinosaurs killed only ~40%.

 

Methane is ~20x the green house gas. the Permian extinction was likely triggered by bolide impact.

 

actually it depends if you go by volume or weight, and other factors.

With respect to Permian–Triassic extinction event there is still disagreement but it was a 3-stage chain event, which started with impact in Australia. Impact caused the Siberian Traps eruption, biggest in the history of the planet.

Eruption caused global warming. It took ~100-200,000 years but it heated up planet by 5C, melted ice caps and stopped oceanic currents. ~10% of terrestrial life died out in process.

Methane belch was a last straw, result of warming caused by eruption.When it happened, temps jumped another 5C and majority of life died out in 8-12,000 years.

 

Time to put you sardonic humor cap on.

 

actually there weren't any intent to be humorous.

It was not by any means a sarcastic or sardonic remark; there are some things we humans should do while we have time.

 

^^ I meant Tony's post.

 

the question becomes what can you do, besides driving Prius?

The other factor is whatever critical impact may be, it will not happen for millennia.

Sort term changes are inconveniences at worse, and there are some positive effects of warming up and ice melting.. for example prime beach property on Georgian Bay, North-West passage, etc.
