    How arrogant of you, as if you're smarter than everyone else because they don't believe global warming is a big issue.

    I suppose you're talking about the very long term trend where there's been a 3X increase since 1750. Things have stabilized relatively in recent decades though, as your graph shows. What I want to see is how even a 3-fold increase affects the atmosphere, and that doesn't mean it's likely to happen again anytime soon. A back of the envelope calculation is CH4 increased from 0.6 to 1.8 ppm, while CO2 increased from 280 to 380 ppm. CH4 is 25X more potent than CO2, so the CH4 increase is 30 ppm if it were "converted" to CO2. So the 3-fold CH4 increase accounts for ~25% of AGW so far, significant but not catastrophic, since AGW is probably about 1 °C so far. Basically, very extreme releases, well more than anything we've seen, will be needed to really cause some climate change.

    Your chart is in nanomol/mol, the CH4 is ~1000 so it's in micromol/mol. The change in CH4 is on the order of about 10-100 nanomol/mol.

    Note that the amounts are in nanomol/mol, there's not much CH4 to begin with, and it's only increased slightly relative to the total amount of CH4.

    It must be different everywhere. Wisconsin had a major focus on forecasting the weather along with the science. Synoptic meteorology, mesoscale meteorology, and radar and satellite took me from a novice to actually knowing what I'm doing. Other classes added bits and pieces to the forecasting puzzle too.

    NWS in Fairbanks is calling this the deepest storm in 35 years. They're saying it could wipe out Kivalina on the Bering Sea coast. Only 400 people but they need to get the heck out of there.

    Wow!!!

    Perhaps JoMo's lull was the time inbetween 'microvortices' on the outer edge of the tornado, since it sounds like he only got clipped thankfully. The convenience store lull seemed like the time inbetween the outer edge of the tornado (where there are many vigorous microvortices) and the main vortice in the center. This is all speculation though.

    There is a such thing as too much CAPE, it can lead to rapid upscale development so discrete supercells won't last long.

    Pilots do not fly over supercells, the updraft easily goes into the lower stratopshere.

    A friend of a friend FB status from the univ of alabama: "Oh my god...there are no words. my heart just broke....everything is gone."

    Eoline, AL about to get a direct hit from a 110 kt couplet with a debris ball.
  13. turtlehurricane
    Less than 20 minutes until this tears through downtown Birmingham.
  14. turtlehurricane
    Might be a small tornado forming on the RFL, going through downtown...

    Just prior to hail from the cell attenuating the signal, it was detecting a 200+ kt couplet at 1200 ft.

    The supercell approaching Tuscaloosa, AL is getting its act back together.
  18. turtlehurricane
    This one might be heading for Chattanooga.
  19. turtlehurricane
    Debris ball just got alot more intense with a 180 kt couplet NE of Pisgah, AL.
  20. turtlehurricane
    200+ kt couplet just north of Moore's bridge, AL?!?!
  21. turtlehurricane
    Fairview AL is about to get hit with a vigorous couplet.
  22. turtlehurricane
    Definite debris ball over Smithville, AL, 140 kt couplet. Wow...
  23. turtlehurricane
    Might be seeing the first signs of debris on radar from the 120 kt couplet that just went through Bigbee, MS. Heading directly for Smithville.
  24. turtlehurricane
    Phil Campbell, AL, just took a direct hit from a 160 kt couplet.
  25. turtlehurricane
    A medical center has been hit in Cullman. Anyone save the tower video? I'm dying to see it.
