They tell us that levels of carbon dioxide (CO 2) in the atmosphere are higher than they have been at any time in the past 400,000 years. During ice ages, CO And now we’ve done the next 25 per cent in a little over 30 the Met Office projects that average CO2 concentrations will be some 2.29 ppm higher at the Mauna Loa Observatory in Hawaii than Right now we’re on track to create a climate unseen in 50 million years by mid-century. *This sentence was edited after posting to correct the 1958 ppm level. This article is reproduced with 2019-04-04 · The current CO2 concentration of 410 ppm is unprecedented over the past 3 million years. Changes in CO2 concentrations dramatically affected how long glaciers covered the Northern Hemisphere. If CO2 level is causative, based on historical Vostok ice core samples….we should have seen a MUCH larger spike in temperature already.

2020-9-3 · Let’s talk about CO2 levels now and what you should be shooting for in your grow room. CO2 is measured by parts per million (PPM). A normal outdoor reading of CO2 would be 300 to 400 PPM and indoors is approximately 500 to 800 PPM. The CO2 range for your grow tent or room should be somewhere around 800 to 1100 PPM.

During ice ages, CO 2 levels were around 200 parts per million (ppm), and during the warmer interglacial periods, they hovered around 280 ppm (see fluctuations in the graph). "It's halfway now between the pre-industrial level of CO2 in the atmosphere [280 parts per million] and a doubling of CO2 in the atmosphere. So that's quite profound," said Professor Andy Pitman CO2 levels are updated daily with data directly from NOAA's science lab on the slopes of Moana Loa volcano on the Big Island of Hawaii. Atmospheric carbon dioxide measurements have been collected here daily since 1959.
