Has the temperature of the sun changed ?

It does not appear that the sun has changed its power level much, if at all, in the last several hundred million years, and theoretical studies indicate that this extends back considerably farther. The earth has gotten slightly farther from the sun than it was a billion years ago, due to tidal effects. but the change is too small to be significant. The sun is expected to continue at about the present power level for another five billion years or so, when, having run out of hydrogen fuel at its core, it turns into a red giant and eats the earth.

The temperature of the Sun hasn't changed. But the effect of the sun's rays on Earth has, due to the depletion of the ozone layer.

All of them are Wrong.. Coz the temperature jus varies day to day bcoz if fussion of hydrogen into helium.. its only that ozone is getting depleted and therefore we feel as the sun is becoming hotter... so itz not that sun is getting hotter but we a re feeling the heat coz.. of the ozone hole.. Hope this helps you

Well the sun hasn't gotten hotter, primarily because it's a supernova and in a couple of light years will die out. But our protective atmosphere is thinning and that causes the increase in temperature. As opposed to the temp we experienced like 10, 20, 30 years ago

The sun's output has always been variable. It's been running hot. Earth's human activity, and Bush and Clinton's failure to sign Kyoto, are not responsible for Martian warming. That's just another one of those inconvenient facts.
But let's ignore it. Can't get grant money with that tactic...

yes it's hotter now as the ozone is becoming bigger n bigger,the sun can penetrate directly towards the earth.

We haven't had the technology long enough to make the measurements to predict any differences. Any answer would be a guess.

No, the Sun is the same, but we feel it hotter...the reason, the ozone layer.
