In its annual report on the concentration of the gases, the UN-dependent body indicated that the global average concentration of carbon dioxide (CO2), the main gas causing the greenhouse effect reached 407.8 parts per million in 2018 .056% more than in 2017. This implies a concentration equivalent to 147% of that registered at pre-industrial levels (of 1750), and an annual increase above the average of the last 10 years, according to the observations of the Global Atmosphere Surveillance Network, which has stations in the Arctic, mountainous areas and tropical islands. WMO Secretary-General Petteri Taalas recalled at the press conference presenting the report that CO2 can remain centuries in the atmosphere, and even more in the oceans so that its concentrations are one of the most serious problems. He said that the last time such high concentrations of CO2 occurred was between three and five million years ago, and then the temperature was two to three degrees warmer and the sea level between 10 and 20 meters higher than the current one. https://www.newsroompanama.com/environment/environment-greenhouse-gases-hit-record-high Quote Link to comment Share on other sites More sharing options...

Is there reliable, factual data which reinforces that statement ? Quote Link to comment Share on other sites More sharing options...
Ge Vida Posted November 26, 2019 Share Posted November 26, 2019 I'm not going to debate what someone considers a "reliable source" is, but if you want something that's supposed to be scientific, go to NASA and read the page at https://ozonewatch.gsfc.nasa.gov/. 1 Quote Link to comment Share on other sites More sharing options...

But this sounds scary, so CO2 must make up 20% of the atmosphere now, and skyrocketing! Naw, it's less than that. In fact, it's still less than 0.04%. Not 4%, not 4/10ths of 1%. Less than 4/100ths of 1%. So, even though the level is 147% higher than it was in 1750, it is a very tiny increase in a very tiny number. I'm not trying to start a climate debate here. All I am suggesting is that a lot of information lacks any perspective for the casual reader. 2 Quote Link to comment Share on other sites More sharing options...
Hil Posted November 27, 2019 Share Posted November 27, 2019 MAYBE, they took the samples in the mountains of Tennessee and compared them to L.A. lololololololol Quote Link to comment Share on other sites More sharing options...
