Title: SF6 gas in atmosphere is increasing Post by Laugh till you cry on Sep 14th, 2019 at 9:21am
Greed kills.
SF6, Sulphur hexafluoride, "is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate". "It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years." SF6 " is 23,500 times more warming than carbon dioxide (CO2)." Bad news is the norm for the planet. https://www.bbc.com/news/science-environment-49567197 Quote:

So 23,000 times CO2 as a GHG
Future concentration increasing by 75% 9x1.75 = 15.75 parts per trillion So has an equivalent CO2 GHG rate at 15.75x23,000 = 362,250 parts per trillion. Convert trillion to million = 0.3625 parts per million as opposed to 4 parts per million for CO2. Not worrying at all. ;) Laugh till you cry wrote on Sep 14th, 2019 at 9:21am:
Oh noes. |

In China someone is using CFCs so these are increasing in the atmosphere again. Not powerful GHGs but they only very slowly oxidise into a nonGHG.

Lee's not good with maths. Out by a factor of 100x for CO2 which is currently 410-415 PPM. |

So it's even less than a problem they thought. ;D ;D ;D ;D |

But lee is a bigger problem demonstrating the failure of the WA education system. |

Nope. The education system worked fine for my calculations. The memory failed on the 400ppm. |

Senile dementia has that effect. Don't walk into a corner. You might be unable to find your way out. |

“we've seen almost a doubling of the atmospheric concentration in the last two decades."”
Exponential growth. |

That is always possible from such a low base. ;) |

Any base.
