well I really wish our CO2 in Chicago were as effective as in Oregon. Theirs is special and actually gives them warm. Ask socks.So, CO2 emissions cause a reduction in sun spots! Who knew?

Light the fires and kick the tires -- Winter is coming !!!
A former NASA consultant is not the consensus of NASA.
This is an unethical and lying OP.
Climatologist John Casey, a former space shuttle engineer and NASA consultant, thinks that last year’s winter, described by USA Today as “one of the snowiest, coldest, most miserable on record” is going to be a regular occurrence over the coming decades.
Record cold in half the country this weekend...............

You forgot to say it's "climate change". Always remember, "Global warming" when warmer..."Climate Change" when colder.
cult book, much less waste money on buying it?Why would anyone read yet another denier doomsday cult book, much less waste money on buying it?
If you think it's going to be so impressive, then you buy it, read it, and come back and argue the points.
Thank you for that Article, Mr. Flacaltenn, it definately pointed out the sensitivity to forcing of those glaciers. In fact, it warned of that in the Conclusion;Since I was adding to my AGW file --- I thought Mr. CrickHam would like another..
Solar modulation of Little Ice Age climate in the tropical Andes
Abstract
The underlying causes of late-Holocene climate variability in the tropics are incompletely understood. Here we report a 1,500-year reconstruction of climate history and glaciation in the Venezuelan Andes using lake sediments. Four glacial advances occurred between anno Domini (A.D.) 1250 and 1810, coincident with solar-activity minima. Temperature declines of −3.2 ± 1.4°C and precipitation increases of ≈20% are required to produce the observed glacial responses. These results highlight the sensitivity of high-altitude tropical regions to relatively small changes in radiative forcing, implying even greater probable responses to future anthropogenic forcing.
It's a real shame that a couple clowns SHOUTING like Mann and Hansen -- can drown out all the science that makes their statements look stupid... Like the LIA and MWP were just European things.. Hell -- many of the hockey sticks virtually ignored the tropics.

Conclusions
The data presented here suggest that solar activity has exerted a strong influence on century-scale tropical climate variability during the late Holocene, modulating both precipitation and temperature. Surface cooling is enhanced at high altitudes by feedbacks involving water vapor, ultimately depressing temperatures in the Venezuelan Andes by −3.2 ± 1.4°C during the LIA. It is likely that this mechanism also may serve to amplify the effects of warming trends, irrespective of their origin, which raises concern that global warming will adversely affect high-altitude tropical montane regions (41). Supporting this concern, 20th-century temperature increases have raised the ELAs of tropical glaciers, leading to accelerated ablation and disappearance in many cases (12, 42–44). Our data suggest considerable sensitivity of tropical climate to small changes in radiative forcing from solar irradiance variability. Conservative estimates of net anthropogenic greenhouse-gas radiative forcing for the next 50 yr surpass that of solar forcing in previous centuries (45), implying that profound climatic impacts can be predicted for tropical montane regions.
Intuitively, it would seem that cooler temperatures and lower absolute humidity would lead to less precipitation in the Venezuelan Andes during the LIA. However, this view may be reconciled with the paleoclimate data for increased precipitation at the study sites by recognizing that it is the transport of moisture to high elevations that most likely controls the precipitation amount, as has been clearly documented for the Bolivian/Peruvian Andes (38). During the LIA, a steeper latitudinal temperature gradient induced stronger easterly trade winds (20), which may have actually enhanced the transport of moisture to the Venezuelan Andes. Thus, greater moisture flux may have more than compensated for the reduced atmospheric water-vapor concentration.
Were below the prediction by 15..
And were dropping faster than they thought..
Mirror image of Sun spot cycle 3.. which, if the cycles continues to repeat itself, will be followed by very low cycles like 4 and 5 were...
The LIA was triggered by this last time and earths temp dropped 2 deg C in short order.. Guess where we are today.. On the edge of the cliff about to fall...Just like the last time..
And record warmth last year, the year before, and, very likely, this year. Now if we had our normal solar cycle, we could really be enjoying a warmer year, right?For anyone who needs a visual of what a "quiet sun" looks like without sun spots or indications of activity -----

Explain what a normal "solar cycle" is.And record warmth last year, the year before, and, very likely, this year. Now if we had our normal solar cycle, we could really be enjoying a warmer year, right?
Because they NEED more precipitation to BUILD a glacier during the cool periods.
