Here is some proof that the answer to that question is surely "Not very well". I guess Algore wouldn't agree with me but I think that this one tells us a lot more about it all than either the government or media have.

Only a liberal could call a gas that is essential to life on earth "hazardous to humans" and get away with it.

I guess since the word got out about the CCX some air has been let out of the progressive climate balloon.

The only gas that is hazardous to humans is the gas that comes out of liberals every time they open their mouths, otherwise known as liberalism.

Hypercapnia - Wikipedia, the free encyclopedia

Quote:
Hypercapnia or hypercapnea (from the Greek hyper = "above" and kapnos = "smoke"), also known as hypercarbia, is a condition where there is too much carbon dioxide (CO2) in the blood.

Symptoms and signs of early hypercapnia include flushed skin, full pulse, tachypnea, dyspnoea, extrasystoles, muscle twitches, hand flaps, reduced neural activity, and possibly a raised blood pressure. According to other sources, symptoms of mild hypercapnia might include headache, confusion and lethargy. Hypercapnia can induce increased cardiac output, an elevation in arterial blood pressure, and a propensity toward arrhythmias.[5][6] In severe hypercapnia (generally PaCO2 greater than 10 kPa or 75 mmHg), symptomatology progresses to disorientation, panic, hyperventilation, convulsions, unconsciousness, and eventually death.[7][8]

There's great article on this by Spencer with graphs.

50 Years of CO2: Time for a Vision Test « Roy Spencer, Ph. D.


Note the graph is only showing 1% of the scale because you wouldn't be able to see increase otherwise.

Yes, according to Wikipedia: The U.S. National Institute for Occupational Safety and Health states that carbon dioxide concentrations exceeding 4% are immediately dangerous to life and health although physiological experiments show that such levels can be tolerated for some time.

While, like you say, it may take some time for the average level of CO2 in the atmosphere to reach the 4% or so,(currently it is about 0.04%) the burning of fossil fuels since the 1800s(industrialization) has increased the level of CO2 in the atmosphere by about 40% since that time. Along with the increase in the burning of fossil fuels, the average global temperature since 1900 has increased by about 1.2 degrees Fahrenheit. So while it may take a while for the carbon dioxide to reach a level where it immediately affects our health, fossil fuel emissions are speeding that time frame up. Unfortunately, one could say that we are already being affected by the rise in carbon dioxide levels through the climate changes we are experiencing.

The government and the media have not regurgitated global warming denialism talking points and I am not happy.
Sorry, had to fix that title to match the article.

I didn't say it will take "some time", I said 40,000 years. We couldn't even do it if we wanted because there isn't enough fossil fuel material on the planet to reach those levels.

Heck, conservatives don't believe anything to do with science.
After all, carbon dioxide is not mentioned in the bible.

We don't need no stinking trees.

It's the sun and not humans. Of course there is climate change and carbon dioxide in the air.

Anyway you all make them close down places like China and India first where they use no filters and pollute like it is ordained by god to do so.
