Even for you, Ray, that is a very shallow statement.
Hint: "What make us 'human?' Can that survive 800
ppm CO2 easily?

I see your point--nobody wants to go outside only wearing a moonsuit.
But I was simply saying that humans can survive 800 ppm C02. It is
uncomfortable but survivable. Kind of like breathing fumes in a
crowded freeway.

As for toxicity, here is what OSHA says: "OSHA has indicated that the
lowest oxygen concentration for shift-long exposure is 19.5%,
corresponding to a carbon dioxide concentration well above 60 000 ppm
(6%). Carbon dioxide concentration, not oxygen concentration, is
limiting in such circumstances."

Not that I am advocating we go to the limit, but from 381 to 60k is a
ways to still go.

The earth would likely cook long before it ever got to those
concentrations (60K), so what is your point?

I think his point is that we don't have to worry too much about the air
becoming unbreathable from the amount of CO2 we are adding to the
atmosphere.

Umm, of course, the SO2, particulates, and cancer-causing agents in the
filth belched into the atmosphere will kill you long before the CO2
concentrations ever got high enough to choke you. But even if that were
not the case, the earth would still likely cook before CO2 concentrations
ever got high enough to smother anyone.

LOL El Guapo!

You are correct--that's what I meant. At least you can read, which is
better than the rest of the people here.

No, it's just those multiple global warming induced category 5 hurricanes,
year after year after year, plus the droughts and floods and wildfires and
all those other pesky little agricultural problems.

Then the nuclear proliferation and oil blackmailing and water wars.

Plus the whole overpopulation thing. Loss of habitat.

Global mass extinction. Minor little problems all.

Did I miss anything?

Yeah... human sacrifice, dogs and cats, living together... mass hysteria!

That would be funny except that there is an unmarried couple here who
are desperately trying to keep the home they've made together for 15
years-- one local board of aldermen has 'got religion' and are issuing
eviction notices for couples living in sin based on some law from the
1950s.

What makes it "official," Thomas? Do you have a URL?

I wasn't aware that to be an "official" something, that the something had
to have a URL.

The problem is that Ray is human and can survive 800 ppm of CO2 easily.
He bases his assumption that the social infrastructure that keeps him alive
will still be there to support him.

Ya, we saw a lot of that during the Bush's Katrina Fiasco.

Vastly more is expected.

I would have thought the phrase "BBC News has learned" would qualify
more as an oxymoron than as anything else.

You are thinking of AmeriKKKan newsmedia Fred. The rest of the world has
higher standards for it's mainstream broadcast media.

You will note that the BBC's report is exactly correct, while the
AmeriKKKan mainstream broadcast news media hasn't bothered reporting
anything, and the U.S. mainstream print media is busy trying to hush up news
of YET ANOTHER CASE OF MAD COW DISEASE FOUND IN THE UNITED SNAKES OF
AMERICA.

Most of us don't live on top of active volcanoes (which emit CO2, by
the way).

What's the measure look like where people live?

Pretty much the same. The atmosphere is well mixed, and no matter where
you look - and there are now something on the order of 100 monitoring
stations at varous latitudes around the earth, the average concentration of
CO2 is measured to be essentially the same.

Stupid... Stupid... McCall...

And now at 3 ppm, soon to be 5 ppm, it's more than just a few ppm/y.

The trend does appear to be quit linear over the last 30 years - although
not earlier. Like you, I expect this to change for the worse in the not so
distant future, but I think that without evidence to the contrary, a linear
projection is best.

That puts doubling in 150 years or so.

The problem is that Ray is human and can survive 800 ppm of CO2 easily.
He bases his assumption that the social infrastructure that keeps him
alive
will still be there to support him.

He also assumes that the environment in which we all live could sustain
such levels. I don't think there is any precedent for that assumption.
