The scale on the right for temperature is a change of about 2 parts per 255 degrees Kelvin. The scale on the left is about 3 parts in 1361. It's not clear whether the much smaller variation in irradiance would be expected to cause the much larger change in temperature. Seems unlikely, since the power radiated by a black body varies as the 4th power of the temperature (Stefan-Boltzman law).
