When measurements of carbon dioxide were first taken in 1958, it measured 315 ppm.
To give a perspective on this, the standard amount of sanitizer in a bar sink is 200 ppm.
The warming effect is similar to that predicted from an elevation of the atmospheric CO2 concentration to 720 ppm.

Princeton University climate scientist Michael Oppenheimer said the momentum in carbon dioxide emissions has the world heading toward and passing 450 ppm.
On the opposite end of the spectrum, the Red Devils spent a massive twenty-seven weeks at or above a 2.0 4-match running average PPM and nine weeks and counting at a 3.0 PPM.
The rate of this rise has been accelerating, from 0.7 ppm per year in the late 1950s to 2.1 ppm per year over the last decade.
When we started monitoring it at Mauna Loa in 1957, CO2 was growing at about 0.75 ppm annually.
Prudential already owns U.S. subsidiaries Jackson National Life and PPM America .
Despite a lingering economic downturn in much of Europe and North America, CO2 levels climbed to 394.97 parts per million (PPM) last week, marking an increase of nearly 1.6 ppm compared to last year and the highest level on record.
Before we started torching carbon stored in forests and then carbon stored underground as coal and oil, the carbon dioxide concentration of our atmosphere was about 280 parts per million (ppm).

More specifically, RCP2.6 means CO2 peaks out at 490 ppm and then declines.
At that point he began a slow erosion in performance that culminated in a -0.227 PPM by his sacking after match 27 (-8.6 points over 38 matches, or a nearly 16 point swing).

We are, as of today, at 388 ppm and rising at about 2 ppm per year.
The Dora the Explorer Backpack contained an estimated 16, 200 ppm of DEHP.

Concentrations of CO2 in the atmosphere currently stand at 385 parts per million (ppm) and are rising at a rate of two ppm per year.
The Dora Backpack also contained an estimated 69, 300 ppm of DnOP.

Back then, it took 7, 000 years for carbon dioxide to reach 80 ppm, Tans said.
Last year, regional monitors briefly hit 400 ppm in the Arctic.
City also only hit the 3.0 PPM threshold twice this year, while last year they were able to put together and maintain four-match win streaks nearly four times as frequently.
Using a technique called secondary ion mass spectrometry, the team determined that the mantle from which the meteorites derived contained between 70 and 300 parts per million (ppm) of water.

Twice this season City fell at or below the 1.0 4-match running average PPM barrier, something they never did last year.
Earth's mantle, for comparison, holds roughly 50 to 300 ppm water, researchers said.

Spurs fans may now be dreading another collapse like last season (first graph below) as Tottenham has dropped below a 1.0 4-match running average PPM for only the second time this season (second graph below).
On a 4-match running PPM basis Chelsea have now earned an average of 2.0 or more points per match for the last four matches, and now have the highest 4-match PPM after Arsenal had led the three teams for the last month of play.

According to Roberto, the wastewater starts with about 35, 000 parts per million (ppm) of gunk and junk.
The highly toxic H2S (hydrogen sulfide) and CO2 (carbon dioxide) are removed along with excess water to get the gas below 7 ppm (parts per million).
