The trend left after averaging over the solar cycle is even smaller.

how can a Sun that has constant TSI (averaged over a solar cycle) during 1950 - 2000 play any role in the global warming that was at its strongest over that period

Certainly, but whether high or low, if the Sun is going to influence global warming then how can a Sun that has constant TSI (averaged over a solar cycle) during 1950 - 2000 play any role in the global warming that was at its strongest over that period?

Not exact matches

For example, 2005 is near solar minimum in the 11 year cycle, and radiance now is about 1 - 2 W / m ^ 2 less than a few years ago, which means Pluto and Mars are getting LESS solar radiance on the time scale of the atmosphere and polar cap changes, EVEN IF the radiance averaged over the whole cycle was higher.

The mean insolation at Earth orbit is about 1366 W / m ^ 2; the peak - to - peak variation over the 11 year solar cycle is about 3 W / m ^ 2; the authors discuss two running averages derived from different satellite data sets and analysis derived by Willson and Mordvinov (2003) and Frohlich and Lean (1998) respectively.

Narrowly scoped, the present situation is either strictly caused by solar variations (in which case I believe the «solar variation» crowd will inappropriately gain credibility over the next 10 to 20 years as we work through the next below average solar cycle or two), or strictly caused by CO2 concentrations (in which case I believe the «CO2 concentrations» crowd will inappropriately lose credibility as the non-linear relationship (sensitivity is based on doublings, not linear increases) between increased CO2 concentrations, and forecasts for below average solar cycles reduces the longer term upward trend in global temperatures).

The mean insolation at Earth orbit is about 1366 W / m ^ 2; the peak - to - peak variation over the 11 year solar cycle is about 3 W / m ^ 2; the authors discuss two running averages derived from different satellite data sets and analysis derived by Willson and Mordvinov (2003) and Frohlich and Lean (1998) respectively.

ferd berple says: April 12, 2011 at 1:52 pm Averaging temperature over 30 years to yield climate pretty much guarantees you are not going to find any 11 year solar cycles affecting the climate.

Averaging temperature over 30 years to yield climate pretty much guarantees you are not going to find any 11 year solar cycles affecting the climate.

The full amplitude of solar cycle forcing is about 0.25 W / m2 [64], [71], but the reduction of solar forcing due to the present weak solar cycle is about half that magnitude as we illustrate below, so the energy imbalance measured during solar minimum (0.58 W / m2) suggests an average imbalance over the solar cycle of about 0.7 W / m2.

IF the sun really has started a couple of slower than average solar cycles, and IF the current slight cooling trend continues or becomes even more pronounced over the next couple of decades, we can bury the CAGW scare, along with all the other doomsday scenarios and scares that preceded it.

Well, you start by averaging over at least one period of the cycle; eg to cancel out day / night you take 24 hours, for summer / winter 12 months and for the solar cycle 11 years.

Therefore, we assume that the existing proxies of the solar activity averaged over a two solar cycles period can also describe the activity of the quiet Sun.

The natural causes of climate variations that have time scales (century, decadal; e.g. Schwabe sunspot cycles, average solar output during the satellite measuring era,, ENSO / PDO / AMO and the rest of the alphabet soup of «oscillations», volcanism) either don't capture energy over multiple cycles — if I push a child on a swing, his average position doesn't move away from me — or are going in the wrong direction.
