Sentences with phrase «less sun irradiance»
While we might HOPE FOR THE BEST — that there will be a cooling trend (less sun irradiance, etc) to exactly counteract our AGW trend (even so there is the negative effects of CO2, even without the warming — ocean acidification, crop loss to weed, etc)-- we should then be trying to AVERT THE WORST with even more drastic GHG cuts.

According to the skeptics, the solar irradiance isn't very important, it is the strength of the sun's magnetic field (that allows or stops cosmic rays from coming in which then causes more or less clouds, which increases or decreases the Earth's albedo, which then causes warming or cooling of the Earth's surface).
To elaborate on the above, when the sun enters a prolonged solar minimum condition an overall reduction takes place in solar spectral irradiance, namely in UV light (wavelengths less then 400 nm).
The study posits that one of the reasons for less than perfect fit of sunspot and irradiance data with temperature is that the Sun actually works on a 21 year cycle when the sunspot cycle is combined with the cyclical wobble of the Suns motion through space.
