Earthshine Draft Report – Albedo

Now here is a far more interesting trend than Mauna Loa or any other carbon dioxide atmospheric content! It seems some scientists have detected a reduction in the net sunlight reaching Earth. Instead of adjusting the greenhouse multiplier for carbon dioxide in his model, maybe Al Gore should adjust albedo. There is real data behind it! But what for; Al Gore can sell the model no matter how far it deviates from reality. Maybe the greater the error, the better it sells anyway. (Spell albedo, Al; and you can look).

Palle et al: Earthshine Trends 1999-2007
In this paper, we have demonstrated that the agreement between earthshine and CERES reflectances have shown a dramatic improvement after CERES data were re-calibrated and earthshine data were re-analyzed. In the common period, earthshine, CERES along with ISCCP-FD data show a trendless albedo. However, preceding CERES, earthshine and ISCCP-FD reflectances show a significant increase before flattening and holding the increase. This implies a reduction in the net sunlight reaching Earth.

Update, also from the report: “However, a long-term, global albedo database does not exist.” I guess such a database would not be helpful in selling carbon credits. It could however be helpful in understanding Earth’s climate; another good reason not to have one.

What could be the mechanism for such a change? Read The Chilling Stars by Svensmark and Calder for thorough elucidation.

  1. Great report, we’re must do something to save our world now.
    Thanks for share.

  2. […] albedo of Earth is up by what I consider is a large factor, reported in Earthshine Draft Report – Albedo. It certainly looks like we are in store for continued cooling, particular with the turn-over in […]

  3. It appears immediately that this is a political website rather than an objective science website by your insistence on talking more about Al Gore than the science he advertises. Strike one. Then you insinuate that Gore can’t spell albedo and link to a study about difficulties at evaluating the top of atmosphere radiation budget; this, despite the fact that Gore’s pet project DSCOVR would have addressed many of these issues if it weren’t for interference (start here if you like: You imply that Gore would be against such studies. Strike two. Finally, you show a figure that suggests (looking at the figure), reflectance from clouds (preventing light from reaching Earth) has increased since the 1998 El Nino. Such a response is contrary to Lindzen’s negative feedback “Iris” and, if repeatable, would mean that changes to clouds are unlikely to slow anthropogenic global warming. Strike three. You’re out. Come back when you grow up.

    • Gore is not interested in addressing any issues. There can be no debate, according to Al Gore.

      Low clouds are like the snow and ice cover of Antarctica which has been steadily increasing.

      Imagine the dark blue of the ocean replaced with shiney, brilliant white low clouds. Instead of the oceans absorbing the energy from the sun, it is reflected, almost all of it, back into space.

      That is what happened during the Little Ice Age(s), and that is what is about to happen again.

      Your hero Gore wants you to freeze to death.

  4. The increase in albedo since 1999 means that 2 W/m2 less radiation is hitting the surface of 2 W/m2. The decrease in albedo between 1984 and 1998 shown in other ISCCP cloud cover data imply 3.4 W/m2 extra of shortwave energy.

    The pattern of global cloud cover doesn’t match the model of high and low cloud respective warming and cooling. i.e the planet should still be getting warmer. A more refined model using tropical cloud cover is a better fit to obsefved ocean and atmosphere temps .
