Climate sensitivity in its most basic form is defined as the equilibrium change in global surface temperature that occurs in response to a climate forcing, or externally imposed perturbation of the planetary energy balance.

First, this improvement in planetary prospects will still leave the global temperature increase more than twice as high as the internationally agreed target of 1.5 ˚C.

In fact there is a gravitationally induced temperature gradient (aka lapse rate) in any planetary troposphere, and thermal energy absorbed from solar radiation in the upper troposphere can flow up that sloping thermal profile restoring thermodynamic equilibrium as it does so, and even entering the oceans.

As Coronal holes can persist for months and years and as the solar wind burst affect lasts for roughly week, a coronal hole has a significant effect on planetary temperature) which reflects all solar activity, and it is highly correlated to global temperature variations in the whole period for which we have datAs Coronal holes can persist for months and years and as the solar wind burst affect lasts for roughly week, a coronal hole has a significant effect on planetary temperature) which reflects all solar activity, and it is highly correlated to global temperature variations in the whole period for which we have datas the solar wind burst affect lasts for roughly week, a coronal hole has a significant effect on planetary temperature) which reflects all solar activity, and it is highly correlated to global temperature variations in the whole period for which we have data.

I have sought the best empirical evidence to show how changes in incoming solar radiation, accounted for by intrinsic solar magnetic modulation of the irradiance output as well as planetary modulation of the seasonal distribution of sunlight, affects the thermal properties of land and sea, including temperatures.

Adding greenhouse gases to the atmosphere will raise planetary temperatures just as surely as adding salt to water will raise the boiling point of the water.

In other words by imagining Earth as Blackbody [perfect absorber, emitter, and conductor of sunlight and heat] one create a uniform planetary temperature.

And to maintain or slightly increase planetary temperature is also very much a global good if — as Ruddiman and other scientists assert — the human production of greenhouse gases is helping to hold our planetary environment in its historic, benignly warm, interglacial mode.»

So why would you think that just because high solar activity corresponded with different planetary temperatures at different times, that was somehow an argument against solar activity as a driver fo climate?

So why would you think that just because high solar activity corresponded with different planetary temperatures at different times, that was somehow an argument against solar activity as a driver of climate?

And until such is explained (as I have) then anyone not understanding the relevant physics can not correctly understand observed temperatures in any planetary surface.

Average planetary temperatures increased by a «net» of 0.7 degrees C (1.3 F) between 1900 and 2000, as atmospheric carbon dioxide levels continued to rise — but not in a straight line: they rose 1900 - 1940, cooled 1940 - 1975 and warmed 1975 - 1995.
