Every corrupt and hierarchically organized, technological species must face the seemingly insurmountable, thermal hurdle. And probably fail to deal with it. Some species must fail abysmally and offer only a basic existence of unbelievably wealthy, sociopathic, commercial warlords. Competing against each other to own ever larger armies of downtrodden peasants and countless more commuting, mindless, worker slaves. All are moving, like zombies, through a smog-ridden, parched and desolate landscape without any foreseeable hope of change. All are working for their own master's toxic and mass produced, ephemeral trinkets, bangles and beads.. The workers even think they compete with each other over which Earth destroying, commuter vehicle makes them seem more important in their own eyes. Or which of this month's, latest mobile communicators ensures they are fully remote controlled and safely contained 24x365 by their distant masters. This is Earth's _present_ condition. It can only get very much worse. Revolution would be utterly meaningless. Russia and Iran tried that and just look at the living hell with which they were so generously rewarded. |

Peak oil is real. There was never any scientific consensus that the Earth was cooling. There was never any scientific consensus that the LHC would create a black hole. There _is_ overwhelming scientific consensus (within the limits of noise, 100%... probably larger than for any other scientific idea, even GR) that humans are warming the Earth and that the consequences are going to be very serious for us. You flat-earthers just make yourselves look silly pretending otherwise. |

The model also shows that DOUBLING the CO2 concentration to 800 ppm has a minimal effect on outgoing heat: T_offset = 0, T_ground = 299.7 K, CO2 = 800 pp,, Upward heat flux = 295.2 W/m² To get the UHF back to 298.5 W/m², increase T_offset to 0.75 K. So doubling the CO2 level increases the ground temperature by 2 K. That doesn't look like a "tipping point." |

"Every other factor" cannot ignore the basic equations of atmospheric reflection, absorption and re-emission. MODTRAN is a well-characterized model used by the US Air Force: https://web.archive.org/web/20080428...et.asp?id=7915 "MODTRAN has been extensively verified and validated against FASCODE line- by-line calculations and measurement data. In a comparison of radiance codes for climate modeling (ICRCCM), MODTRAN was compared with three independent interferometer measurements of up-looking radiance and the overall agreement was excellent." The USAF has been using MODTRAN for a quarter of a century and find it to be quite accurate. Others use it, too. It's strange that someone who doesn't understand it doubts it but accepts other models that he also doesn't understand :-) |
