At 2,500 ppm CO2, compared to 600 ppm, performance was significantly reduced in seven of nine metrics of performance, with percentile ranks for some performance metrics decreasing to levels associated with marginal or dysfunctional performance. Business As Usual scenarios point to ~1000ppm by 2100. I would opine that this is not good.

About CO2… Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm In 2013, CO 2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO 2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air. 2020-06-10 2017-06-30 2021-04-05 A Representative Concentration Pathway (RCP) is a greenhouse gas concentration (not emissions) trajectory adopted by the IPCC. Four pathways were used for climate modeling and research for the IPCC fifth Assessment Report (AR5) in 2014. The pathways describe different climate futures, all of which are considered possible depending on the volume of greenhouse gases (GHG) emitted in the years to >2 ppm.

Maintaining adequate air exchange in your indoor grow ensures that CO2 levels are close to atmopspheric CO2 May 17, 2019 The Mauna Loa Observatory in Hawaii, which has tracked atmospheric CO2 levels since the late 1950s, on Saturday morning detected 415.26 The last time carbon dioxide was so plentiful in our planet's atmosphere was in the Pliocene era, around 3 million years ago. Life on Earth was dominated by Oct 24, 2016 The UN has said the concentration of carbon dioxide (CO2) in the atmosphere hit a record 400 parts per million in 2015.

6 days ago The concentration of atmospheric carbon dioxide surged past 420 parts per million for the first time in recorded history this past weekend,

It has already happened before, but we could never see a month with CO2 Sep 20, 2012 At 600 ppm, CO2 came from outdoor air and participants' respiration.

So to convert from ppm to percent, divide the ppm by 10000: As recently as 1910, atmospheric CO2 stood at 300 ppm – higher than it had been for some 800,000 years at least – but jumped up another 100+ ppm over the next century as pollution levels skyrocketed. Obviously, crossing 400 ppm was a huge symbolic moment, numerically at least, but the symbolism doesn't end there. 2021-01-08 2016-12-04 2021-04-07 2019-03-29 See how CO2 levels have never been higher with this fully interactive Atmospheric Carbon Dioxide (CO2) graph featuring current & historical CO2 levels and global temperatures.
