No it actually doesn't. It doesn't take into account the effect of CO2 on human health. We are already seeing Metabolic Syndrome arising from our bodies trying to compensate for the atmospheric levels we have now.

We hit stuffy room at 600 ppm and will have no fresh air to go to. Our bodies won't be able to accommodate that on a continuous basis. We need to return to fresh air for our bodies to relieve the blood acidosis that occurs. Unfortunately our bodies are having difficulty with that at current atmospheric levels.

OSHA allows 5000 ppm concentrations of CO2 in the work place. There are essentially zero effects of the human body below 1000 ppm. So if you think you are going to suffocate any time soon due to CO2 exposure, you need to examine the science more thoroughly.

In summary, OSHA, NIOSH, and ACGIH occupational exposure standards are 0.5% CO2 (5,000 ppm) averaged over a 40 hour week, 0.3% (30,000 ppm) average for a short-term (15 minute) exposure [we discuss and define "short term exposure limits" STEL below], and 4% (40,000 ppm) as the maximum instantaneous limit considered immediately dangerous to life and health

Can we not hash this out again. We've been over this territory any number of times already. Or at least take it over to the CO2 thread where it is at least marginally on topic. Thanks.

More Fire and Anthrax for the Arctic: Study Finds 21 to 25 Percent of Northern Permafrost Will Thaw at Just 1.5 C of Warming

https://robertscribbler.com/2017/07/25/ ... f-warming/

n the far north, the land is rippling, trembling, subsiding, and blowing up as greenhouse gasses are released from thawing frozen soil. Meanwhile, old diseases are being released from thawing carcasses and presenting a health hazard to locals. Strange processes that are likely to accelerate soon as global warming approaches 1.5 degrees Celsius and between 21 and 25.5 percent of all the vast region of Northern Permafrost thaws out...

warming estimates made from the historical record alone are “potentially biased low"

Committed Warming Inferred from Observations

... The study analyzed past emissions of greenhouse gases and the burning of fossil fuels to show that even if humans suddenly stopped burning fossil fuels now, Earth will continue to heat up about two more degrees by 2100. It also concluded that if emissions continue for 15 more years, which is more likely than a sudden stop, Earth's global temperature could rise as much as 3 degrees.
"Even if we would stop burning fossil fuels today, then the Earth would continue to warm slowly," ... "It is this committed warming that we estimate."

Cases a (black) and b (red) are the equilibria with and without aerosol cooling, whereas case c (purple) includes the effect of removing short-lived climate forcers. Cases d (blue) and e (orange) are scaled with the transient climate response representative of warming within this century. Case d is otherwise equivalent to case c. In case e, it is assumed that carbon uptake on the centennial timescale cancels the remnant warming due to imbalance with past forcing. Displayed numbers are the median and 5th–95th percentiles of the respective distribution. Also shown in grey is the instrumental temperature record12 for 1850–2016, and black horizontal lines indicate the reference periods used to estimate TCR and ECS (Fig. 1). The dashed horizontal lines indicate 1.5 and 2.0 K. All temperatures are relative to the 1850–1899 mean, which is here taken to be the pre-industrial reference temperature (Methods).

... Compared with pre-industrial levels, we find a committed warming of 1.5 K (0.9–3.6, 5th–95th percentile) at equilibrium, and of 1.3 K (0.9–2.3) within this century.
http://www.cnn.com/2017/07/31/health/cl ... index.html

...If we surpass that mark, it has been estimated by scientists that life on our planet will change as we know it. Rising seas, mass extinctions, super droughts, increased wildfires, intense hurricanes, decreased crops and fresh water and the melting of the Arctic are expected.

The impact on human health would be profound. Rising temperatures and shifts in weather would lead to reduced air quality, food and water contamination, more infections carried by mosquitoes and ticks and stress on mental health, according to a recent report from the Medical Society Consortium on Climate and Health.

"This interesting paper confirms the conclusion about where the world is headed unless there is a major increase in the ambition of climate and energy policies," Hare said.


Earth Likely To Warm More Than 2 Degrees This Century

Warming of the planet by 2 degrees Celsius is often seen as a "tipping point" that people should try to avoid by limiting greenhouse gas emissions.But the Earth is very likely to exceed that change, according to new University of Washington research.
A study using statistical tools shows only a 5 percent chance that Earth will warm 2 degrees or less by the end of this century. It shows a mere 1 percent chance that warming could be at or below 1.5 degrees, the target set by the 2016 Paris Agreement.

"Our analysis shows that the goal of 2 degrees is very much a best-case scenario," said lead author Adrian Raftery, a UW professor of statistics and sociology. "It is achievable, but only with major, sustained effort on all fronts over the next 80 years."
"Our analysis is compatible with previous estimates, but it finds that the most optimistic projections are unlikely to happen," ... "We're closer to the margin than we think."

The new, statistically-based projections, published July 31 in Nature Climate Change, show a 90 percent chance that temperatures will increase this century by 2.0 to 4.9 C.

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late.
