Sunspots are not the cause but a manifestation
of changes in the Sun's magnetic field that in turn modulates the intensity of cosmic rays reaching the Earth.
Up to now, most climate models incorporating known forces such
as changes in the sun and atmosphere have predicted that volcanic explosions would disrupt the monsoon by bringing less rain to southeast Asia — but the researchers found the opposite.
«It's an opportunity for us to study
changes in the Sun which will give us newer insights into the origin of the solar wind and its relation to the solar magnetic field,» says Ed Smith, NASA Ulysses project scientist.
Thermometers dropped deep in the ocean and in holes bored in permafrost show warming patterns that do not match up with natural influences
like changes in the sun's brightness.
There is a small but interesting literature looking for amplifiers that might allow
tiny changes in the sun to cause larger changes in climate... However, the few tenths of a degree from such influences are very small compared to the possible warming if we burn most of the fossil fuels».
2) «However, the
recent changes in sun activity are not larger than the one we have in the last 1000 years, while the global warming in that last 30 years is not similar to anything on the record.»
It takes millions of years to compensate, enough for
slow changes in the Sun, but not enough to immediately correct for humans dumping tons of extra CO2 every year.
NSF's Daniel K. Inouye Solar Telescope, or DKIST, will look specifically
at changes in the sun's corona associated with CMEs and solar flares when it comes online in 2020.
However, the recent
changes in sun activity are not larger than the one we have in the last 1000 years, while the global warming in that last 30 years is not similar to anything on the record.
Eyes Genes involved in eye development might help the butterflies detect
fine changes in the sun's position, as well as patterns of polarized light.
The lead authors of a paper in Nature describing
unexpected changes in the sun's spectrum came into the SMC to discuss their findings and the implications for the effects of solar variability on climate.
The study
tracked changes in the sun by looking at previous solar cycles of change, such as Cycle 22 which lasted from the years 1986 to 1996, and found that the oscillation frequencies were confined to a thinner layer than those previous cycles.
With so
much changing in Sun and Moon, it's kind of nice not to have to contend with a frankly excessive number of new creatures.
«Something very different was happening during the 17th Century, and it produced a much more
permanent change in the Sun's energy output at that time,» Rottman said.
In my new book, «IT»S THE SUN, NOT YOUR SUV,» using the Global Warming community's own data, a conclusive proof is made that the zigzag historic temperature record is forced to change by the
major changes in the sun's energy.
He is not a climate scientist, but he's published papers
linking changes in the Sun's output to Earth's temperature, claiming that it's the Sun heating us up, not human - generated carbon dioxide.
«Since irradiance variations are apparently minimal, changes in the Earth's climate that seem to be associated with changes in the level of solar activity — the Maunder Minimum and the Little Ice age for example — would then seem to be due to terrestrial responses to more
subtle changes in the Sun's spectrum of radiative output.
Since a mere two
percent change in the Sun's luminosity would (all other things being equal) plunge the Earth into a deep ice age, one might expect the surface to have only recently defrosted.
Looking ahead, were solar changes limited to what has been measured in the last fifteen years,
future changes in the Sun's total radiation would have only a negligible effect on the temperature increases of 1 to 3 °C that are now projected in IPCC models for the end of the next century.
While changes in the suns output can affect the Earth's climate, the recent warming can not be explained by changes in solar activity.
The pattern of warming that we have observed, in which warming has occurred in the lower portions of the atmosphere (the troposphere) and cooling has occurred at higher levels (the stratosphere), is consistent with how greenhouse gases work — and inconsistent with other factors that can affect the global temperature over many decades,
like changes in the sun's energy.
