    Many, varied.
  1. A really broad yet bite sized view: Do Variations in the Solar Cycle Affect Our Climate System? Note: take the link with a grain of salt: "extensive series of climate model experiments " not all observations. Koma: Yes, and there is some debate around to what degree (pun intended!) NASA's take on a flurry of events a few years back. And some NOAA findings, Ultraviolet or UV wavelengths (120 – 400 nm), the solar irradiance variability is larger over the course of the solar cycle, with changes up to 15%, but many of these shorter wavelengths are blocked entirely by the atmosphere so those never hit the ground... The rest is outside of the sun... but hey, earth's climate is a complex ball of fluid energy too theartist: Perhaps water vapor and clouds moderate temperature swings more than they're currently given credit, and the oceans are slower to give back their heat than expected? (and I have enjoyed your recent visualizations, thanks!) The atmosphere guy: Most air coming down from the top of the hadley cells is cold and dry regardless of solar max vs min, yes? So it isn't so much moving air north that cools, it's air moving heat up that does?
  2. Hi, is the radio flux presented on your solar-activity page the absolute number or is it the adjusted one?
  3. To add a little to the replies of John and Emilio, there are some that would argue that increased volcanic activity contributed or caused the cooling witnessed during the maunder minimum, eg Miller et al. 2012. Some go further. Some think that during solar minimums or transitioning from or into them, the atmosphere shrinks or expands, causing atmospheric currents to change as a result, and the result of that is a brake or push on the planet's spin leading to increased stresses on the surface of the planet causing increased tectonic activity and thus increased volcanism. Others argue that the solar minimum affects the earth's magnetic field, or core movements, and thus causes increased volcanism... there are probably other arguments out there...
  4. Theartist: No need for the ad hominem, please. Respectfully, to some, it reduces the value of your comment. On the bright side, it's why I picked this sunny day here in Maryland to bite on your comment If you look at ir absorption bands of co2, ch4, and h2o and relative atmospheric composition in a convective atmosphere (h2o!), milankovich cycles (obliquity!), co2 ppms and temperature data from antarctica and greenland over 100ks years (which leads which? what are the ppms of co2 in greenland cores?), other energetic events during solar maximum (solar flares, CMEs), the difference in percentage of UV contributing to TSI between solar max and min, solar activity over the last 11k years (1900s!), I think you'll have a bigger picture. Tony Sweany: For some, my guess is well after fingers freeze to the keyboards of some in the northern hemisphere who are banging out articles about global warming. For others, if the next solar maximum is less than the prior one which was the lowest in more than 125 years based only on the number of sunspots, and the earth starts to cool or warm less quickly based on UAH, RSS, or future satellite data while co2 increases, to me and others, that will be the nail in the coffin of the Theory. But even if the Theory is right, a warmer world, on net, is a wetter one and crops do better with more co2. Paleo records show life flourishes during warmer periods... after all, we're in an ice age right now!
