Has the laser at Magurele, Romania reached a tenth of the Sun's power?
It's possible they are actually talking about the rate of energy given off by the Sun that reaches the Earth. However, they are not talking about the amount of energy released, but rather the rate of ...

Does the sound of the Sun oscillate around 528 Hz?
No, it seems that the 528hz claim is either completely made up, or at best based off of recordings artificially adjusted to be heard by humans. The Sun simply doesn't oscillate that quickly or that ...

Is half of the climate change in the past 110 years due to natural variation in the Sun's output?
Probably not.
Sunspots may be correlated with climate change. For example, the famous Maunder Minimum is correlated with the Little Ice Age. Causality is a bit trickier since the mechanism isn't ...

Has non-TSI solar output increased over the past century in ways the IPCC climate models ignore?
A partial answer, based on the 2011 paper, Quantifying the role of solar radiative forcing over the 20th century, by Shaviv and Shlomi Ziskin:
Well, it turns out Shaviv and Ziskin do not make clear ...

Will Earth drift outside of the Goldilocks zone in the next half-billion years?
Ignoring debates about what constitutes the "Goldilocks zone", the issue of the Earth-Sun (AU) distance change is not terribly settled either.
Howard appears to be using data from a somewhat ...

Is half of the climate change in the past 110 years due to natural variation in the Sun's output?
The Sun activity changes every 11 years or so. That's called solar cycle, and one of its manifestations are sunspots. Sunspots irradiate more energy so the more spots the more energy the Sun produces.
