over cloud changes.

There are some various proposed mechanisms to explain this that involve the surface energy balance (e.g., less coupling between the ground temperature and lower air temperature

cloud changes.

cloud over, I rushed him to the vet, they checked the eye and prescribed ointment, it took care of the cloudiness, but did nothing for the bulging or the enlarged pupil, last weekend I noticed redness or blood in his eye, within a day that cleared, then came back with a vengeance, blood took
over the whole eye, rushed him again to vet, they said they couldn't give him a proper examination due to his eye being completely filled with blood, there was no charge, but said it was definitely not trauma and he is too young to be cancer, but there are exceptions to everything, no prescriptions or ointments, said they would do very little and in most cases these symptoms clear on their own, they said to wait and watch, any
change, for better or worse to bring him back, if there is discharge and seems to be healing then they can do a proper exam, if there is more bulging then they'll have to stick a needle in the eye to drain it.

In addition, since the global surface temperature records are a measure that responds to albedo
changes (volcanic aerosols,
cloud cover, land use, snow and ice cover) solar output, and differences in partition of various forcings into the oceans / atmosphere / land / cryosphere, teasing out just the effect of CO2 + water vapor
over the short term is difficult to impossible.
However, lest the previous sentence is taken out of context, we should point out that there is clear evidence that total

I do not doubt the high probability of of anthropogenic factors in current climate
change, but I think the

While on the subject: Could I ask your take on Erlykin et al. 2011, in particular their finding that any effect of cosmic radiation is limited to 1 % of
cloud cover, and their estimate that any temperature increase due to such a mechanism
over the past 50 years of barely
changing CR is limited to 0.002 °C?
«Somewhat counter-intuitively, a land — sea surface warming ratio greater than unity during transient climate
change is actually not mainly a result of the differing thermal inertias of land and ocean, but primarily originates in the differing properties of the surface and boundary layer (henceforth BL)
over land and ocean (Manabe et al. 1991; Sutton et al. 2007; Joshi et al. 2008 (henceforth JGW08), Dong et al. 2009) as well as differing
cloud feedbacks (Fasullo 2010; Andrews et al. 2010).»
Thus it appears that, provided further satellite
cloud data confirms the cosmic ray flux low
cloud seeding hypothesis, and no other factors were involved
over the past 150 years (e.g., variability of other
cloud layers) then there is a potential for solar activity induced
changes in cloudiness and irradiance to account for a significant part of the global warming experienced during the 20th century, with the possible exception of the last two decades.
Also, the brief period I spent scanning abstracts [no time this week to read papers] indicates a difference of opinion suggesting whether there is a correlation between
clouds and CRF (including a no by Balling and Cerveny Theoretical and Applied Climatology 75:3 - 4 pp. 225 - 231 — which may be a good indicator as there was a skeptic flurry last year
over connecting CRF to climate as another try at natural causes being responsible for recent climate
change).
To the contrary, they are at pains to point out that «difficulties in measuring

over the oceans (− 4.2 W m − 2).

-- These storms should penetrate higher as climate warms according to the models, a positive feedback, and satellite data looking at
