As we noted, the LHC will not destroy the world and as George Musser wrote to me after we recorded the interview, «I said something to the effect that scientists had stocked [stoked] concerns about black holes by saying the LHC would create particles not seen since the big bang, but those particles have been seen since the big bang, namely in natural processes such as cosmic ray collisions; therefore if black holes posed a threat, the universe would already be a goner.&raqu

cosmic ray particles.

I bend over backwards to the skeptics
by including the
cosmic ray mechanism
as a central feature of my model.
I conjecture that three changes in the way in which the climate problem is presented
by the experts to the general public would make the conversation go better: acknowledge that climate constraints are unwelcome (thereby establishing empathy with general audiences,
as a doctor does when conveying bad news), present the science
as unfinished (thereby taking away the surprise factor that accompanies every new wrinkle — cf. the
cosmic ray stories of a couple of weeks ago), and admit that no solution is wonderful (something hard for much of our community, which loves some strategy and hates at least one of the others).

I would further characterize the climate system
as a massively complex, chaotic, non-linear, open, coupled system made up of 5 separate subsystems each with their own set of complexities, and all being affected
by externalities like the sun, polarity, gravity,
cosmic rays, and who knows how many unknown unknowns.
In reality there is a huge diversity of opinion within the skeptic side, like: it's cooling; it's warming (but not
as much
as GISSTemp says); whatever the temperature is doing, it's caused
by cosmic rays, or PDO, or sunspots, or recovery from the LIA...; CO2 is a greenhouse gas (but the feedbacks are negative); CO2 is not a greenhouse gas.....
Our analysis also suggests that there is not a solid relationship between
cosmic ray flux and low cloudiness
as proposed
by Marsh and Svensmark [2000].
CLOUD's genesis is in the mid-1990s, when space physicist Hendrik Svensmark hypothesized that
cosmic rays as mediated
by solar effects, play a very large role on the physics of climate, and could explain the warming and cooling trends.
«Because the primary source of ions in the global troposphere is galactic

Cosmic rays may or may not influence climate discernibly, but the effect, if any, has been shown to be small.
I have heard that global climate models have very rudimentary cloud models and do not include such effects of solar /
cosmic rays nor of the correlation with earth's Length of Day (
as impacted
by temperature and wind changes).
The Earth's temperature has warmed in the modern era
as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding
cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (
as illustrated here
by Ogurtsov et al., 2012 and detailed
by Avakyan, 2013, McLean, 2014, and others).
He theorizes that the Earth's temperature has warmed in the modern era

Dr. Fleming further proposes that the Earth may cool
as it slides into a Solar Grand Minimum in the coming few decades (~ 2030) due to a predicted decline in the solar magnetic field and concomitant cloud cover increases seeded
by cosmic ray intensification.
This confirms research
by Henrik Svensmark, Australia's David Evans and others, who correlated low solar activity (fewer sunspots) and increased cloud cover (
as modulated
by cosmic rays), with a cooling climate.

Later, the enhancement of atmospheric aerosol particle formation
by ions generated from
cosmic rays was proposed
as a physical mechanism explaining this correlation.
The sunspot number you show is very controversial, e.g. http://www.leif.org/research/Solar-Activity-Past-Present-and-Future.pdf and http://ssnworkshop.wikia.com/wiki/Home And the correlation is contradicted
by the Figure in the article of this thread: http://www.leif.org/research/HMF-Briffa.png The green curve is solar activity deduced from
cosmic ray proxies of the solar magnetic field
as carried out to the Earth
by the solar wind.
Perhaps not, but solar activity does not follow curve (c): http://www.leif.org/research/HMF-Briffa.png The green curve is solar activity deduced from
cosmic ray proxies of the solar magnetic field

Although it is generally believed that the increase in the mean global surface temperature since industrialization is caused
by the increase in green house gases in the atmosphere, some people cite solar activity, either directly or through its effect on
cosmic rays,
as an underestimated contributor to such global warming.
(There's also the possibility of a warming trend caused
by some other factor, such
as cosmic rays —
as with chance variation, unlikely but not impossible).
(Note: The computer model used considers climate variations caused
by cosmic ray flux, and other possibly major parameters,
as negligible, completely ignoring many recent scientific findings.).
Low cloud amounts vary
as cosmic rays are varied
by strength of the Sun's magnetic field.
I always believed that the oceans were an important element in localised weather conditions over the short term but feel that relatively sudden shifts in climate occur through external forcings such
as volcanic eruptions, meteor strike and the effects of changes in
cosmic rays and sun spot activity, which are, unfortunately, all chaotic
by nature and unpredictable.
