By the looks of it the polar bears aren't going to survive this round of change. Nothing to feel guilty about. It is what it is.

I guess, if you keep reading enough you can find any answer on the Internet...
Q: How much pollution does a volcano produce? I’ve heard that a volcanoes spew out as much pollution as all the cars that have ever been put on Earth
combined but how much pollution does a volcano produce when it erupts?
Asked by Darwin Teague
Hear this Question on our Podcast
- Darwin Teague - 15th Jun 08
A: What you've heard is true.
Beside particulate (ash and other particles), volcanoes can release enormous quantities of gases, including the following pollutants:
H2O water vapor
CO2 carbon dioxide
SO2 sulfur dioxide
H2S hydrogen sulfide
CO carbon monoxide
HCl hydrogen chloride
HF hydrogen flouride
Even non-explosive basaltic volcanoes (Hawaii, Iceland) can release damaging quantities of pollutants in the form of "vogâ", or volcanic smog. The
Hawaii volcano observatory has recently issued warnings for sulfur dioxide emissions and restricted access to areas around Kilauea. The 1783
Icelandic basalt eruption resulted in emission of over 100 tons of SO2 in less than 8 months- killing humans, livestock and damaging crops in both
Iceland and Europe. Gas emissions during the eruption of the Siberian traps may have caused the great Permian extinction 250 million years ago.
Volcanic SO2 emissions can range up to 10 million tonnes per day.

If there were only some way that we could come up to eliminate the co2 after it's there. Surely some there is a brilliant chemist out there somewhere
to invent something we can shoot into space that will speed up co2 consumption to safer levels?
We have always gotten ourselves out of situations and we must do so again. Sound naive?
The current approach is going nowhere. Those who don't want to deal with the mess say what mess? Even the new administrations policies if adhered
would not be enough.
It's not just about the bears and Bangladesh and the South Seas. The temperature of sea currents are changing causing the change of previous plankton
blooms. Will they remain for the whales. Will there be sufficieent for the great salmon runs. Will the forage fish get less numerous? Birds fly
greater distances to feed their young. Life or death. A time of great anxiety for many.

funny thing, i was talking to the FEAD guy at san nic about the crappy fishing and he said it's been about 7-8 years since he has seen ANY baitfish.
he used to see baitballs all the time getting pushed into the shoreline by predator fish...

Really hijacking now...
Have you ever wondered why the fishing in Asuncion is usually so much better then neighboring Abreojos or Tortuga? It's obvious from google earth.
It's the first place that gets cooking once the upwhelling starts. Nutrients to surface baitfish to nutrients and the big boys show up. The
continental shelf is the narrowest at asundion. It's the epicenter. Don't understand the tuna though.

dk: you cited naked scientist website, so i assume you find them credible.
here is an interesting Q&A from naked scientist website:
=========================
Is global warming all made by humans?
I have been learning about environmental science in school (I just graduated), and have been confronted with an alternate view of global warming. My
textbook tells me that global warming is entirely anthropogenic, but I have heard from some sources that the earth has cycles in which it heats and
cools. These sources suggest that we are simply going through another one of these warm periods, and that the large amounts of carbon dioxide,
methane, etc. are not significantly affecting the environment. How do you respond to this proposition? How have other scientists responded to this?
Jeremy Conrad (via email)
[We put this question to Jonathan Shanklin, who discovered the hole in the ozone layer and was our guest on the Atmospheric Analysis show]
The Earth does go through regular cycles of warm and cold, and we are currently in one of the warm periods. The cycles are clearly shown in Antarctic
ice cores, which show several cycles over the last 750,000 years, each one lasting around 120,000 years. Carbon dioxide levels and methane levels are
high during the warm periods and low during the cold periods. The main driver behind these changes are variations in the Earth's orbit, and these
would suggest that we should now be heading towards a very slow cooling.
We have however changed our atmosphere so fundamentally that carbon dioxide levels are much higher than at any time in the last 750,000 years. This
much higher level of carbon dioxide (30%) is what is giving rise to the anthropogenic global warming. We are probably committed to at least a 5
degree rise in average global temperature. This will have dramatic effects on ice cover and sea level. The need to cut carbon dioxide levels so
urgently is to prevent things getting even worse. The problem is actually even greater than this, as in the developed world we are consumming the
resources of over three planets. This is not sustainable as we only have one planet!

another Q&A from David K-approved naked scientist!!!!!
Could volcanoe ash relate to global warming?
I've heard that the eruption of Krakatoa causes massive cooling in the atmosphere and these effects are diminishing. Could this be a contributing
factor to global warming? Simon via Email
The particles that go into the atmosphere from volcanoes do cause cooling but it only tends to last for a couple of years before the particles all
drop out again back to the background level. You'd have to have really big volcanoes going off all the time into the upper atmosphere to really have
an effect like that.

perfect! total ambiguity.... hey, summer is coming so don't expect snow in july! so what if it was the warmest march in 150 years? that isn't long
enough to matter in the scheme of things...

I think what he is saying is that the main driver--in the past---has been orbital change. The current spike in temp is more puzzling since its out of
sync with that model.

The discussion around "Al Gore's Math Problem" seems to provide acceptable numbers, and they say that our atmosphere is only about nine times larger
in volume than our oceans. No one who has been out of the sight of land for weeks can fail to get a sense of the mass, yet man has *done a job* on
most everything that is good to eat that once lived in abundance there. Why is it so hard for some folks to accept that there is an excellent
possibility, at least, that some climate change is also man-made.
That life on this planet evolved an animal with such a brain that it can, and will, dissect the finest nuances of the causes if its demise while
failing utterly to organize socially in a way that might have made human life here sustainable is the closest understanding I've gained of cosmic
irony.
There's a great discussion between the biologist Richard Dawkins and Neil deGrasse Tyson the astrophysicist in part about the probabilities of life
throughout the cosmos and the probability that that life might look like us.
http://www.youtube.com/watch?v=QuR3AmOi50A
It is a fascinating discussion. Dawkins is a little too serious for Tyson but they are true brainiacs. Skip in 20 minutes.

Hey in "my little world" it is the fine art of comma-splicing.
Check out the video I edited-in above.
