Per Michael Mann the MWP did not exist so how could
increased radiation from the sun be responsible for it????

It's found out that natural UV
radiation from the
sun may
increase by about 25 % at the beach, as it is reflected by the water and yellow sand.
Given the revised timeline in this region, Willenbring and colleagues determined that the
increased precipitation resulted
from changes in the intensity of the
sun's
radiation on the Earth, which is based on the planet's tilt in orbit.
The ozone layer is crucial since it blocks out the harmful ultraviolet
radiation from the
sun known to
increase the risk of skin cancer and cataract damage, in addition to other harmful effects on plants and animals.
I ask because my limited understanding is that temperature is related to kinetic energy, but would not register an overall
increase in potential energy, in which case energy
from the
sun could be partitioned in heat energy emitted
from the planet and work used to
increase potential energy, possibly allowing an energy balance that does not require a
radiation balance, and also does not require a warming effect.
The
increasing greenhouse effect leads to a
radiation imbalance: we absorb more heat
from the
sun than we emit back into space.
The temperature around the world is now
increasing and TSI (Total Solar Irradiance) I think solar cycle can cause global warming because our temperature is
increasing by
radiation from the
sun which comes
from solar cycle too.
If the amount of energy received by the Earth
from the
Sun exceeds the amount the Earth radiates into space, then the only thing the Earth can do is
increase its temperature, which in turn will
increase the amount of
radiation into space.
Is it not also therefore true that the polar areas of least water vapor, where a greater temperature
increase from doubling of Co-2 would have the most effect, has the least W / sq - m percentage of both incoming S - W and outgoing L - W
radiation due to the incident angle of incoming
Sun light, the high reflectivity of the snow and ice, and the greatly reduced outgoing L - W
radiation due to this?

So we can blame the
sun for the Holocene period, but even though solar
radiation has
increased right along with the temperature in the 20th century, we are assuming that the warming is due to the minute
increase of atmospheric CO2
from humans?
When sunspots are on the limb of the
Sun — just rotating onto or off of the face — the plage are prominent
from our vantagepoint, creating a significant
increase in
radiation that far outweighs the dip of
radiation caused by the rest of the sunspot's transit.
Clouds are capable of both
increasing the residence time of some LWIR
radiation from the surface, and decreasing the residence time of SW insolation
from the
Sun.
With a small decrease in
radiation from the
Sun — or an
increase in ice cover — the system becomes unstable with runaway ice feedbacks.
When SW
radiation from the
Sun interacts with matter (the Earth, for example) it imparts energy to the receiving molecules which can
increase the thermal energy of the matter — it fills the «energy gap» required to reach the next energy level (warm).
«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared
radiation from the
sun, and approximately doubling the temperature rises predicted
from atmospheric CO2
increases.
The theory is that the Ozone Hole, by allowing more of the UV component of the
Sun's incoming
radiation to make it down to low altitude rather than being absorbed in the stratosphere is providing an incremental energy
increase to drive the strength of the SAM, and thus the degree to which Antarctica is isolated
from more global weather influences.
In this new study scientists
from Germany, Norway, France and the UK used four different computer models that mimic the earth's climate to see how they responded to
increased levels of carbon dioxide coupled with reduced
radiation from the
sun.
The recalculation of 0.0163 K / year gives the
increase of the power density due to the
increase of CO2 in the order of magnitude of 0.1 W / m ^ 2 per year as compared to the total available average power density of 550 W / m ^ 2 (which includes the mean value of the irradiation
from the
Sun and the back
radiation).
By applying what has been learned about solar
radiation changes
from the recent measurements
from space, we can infer that this gradual build - up in solar activity over several hundred years may have been accompanied by a parallel
increase in the
radiation received
from the
Sun.
The
increase of CO2 gives both the higher value of Tl due to the
increased absorption of the outgoing surface
radiation and the higher value of T after the
radiation from the
Sun is «switched off» at the evening.
As the transport of
radiation outward becomes less efficient, the temperature of the earth's surface must
increase to reach a power balance with the absorbed light
from the
sun.
The temperature
increase of the hotter surface, whilst happening only if the back
radiation is happening, still comes about because of the impinging heat
from the
sun.
The
increased clouding during periods of cosmic ray maxima and
sun spot minima may ensue
from decreased solar
radiation and lesser cloud dispersion.
