irradiance

• Indeed, a look at a graph of solar irradiance from the National Oceanic and Atmospheric Administration shows little solar activity during the Little Ice Age and significant activity during recent times. —  GREENIE WATCH
• A 12-year low in solar "irradiance": Careful measurements by several NASA spacecraft show that the sun's brightness has dropped by 0. 02\% at visible wavelengths and 6\% at extreme UV wavelengths since the solar minimum of 1996. —  WHAT REALLY HAPPENED
• We live in a more precarious world now that there is more solar irradiance, but it would be quite foolhardy to push our climate into runaway warming a billion years before its time, when the sun goes supernova. —  RealClimate
• Solar irradiance: The solar output remains low (Fig. 4, below), at the lowest level in the period since satellite measurements began in the late 1970s, and the time since the prior solar minimum is already 12 years, two years longer than the prior two cycles. —  Climate Progress
• In that case, the negative forcing, relative to the mean solar irradiance is equivalent to seven years of CO —  Climate Progress
