No. The Sun will not become a red giant star for another 5 billion years. If the Sun were causing global warming, all the planets would be experiencing it. And they aren't.
Light from the Sun in the visible spectrum comes in through our atmosphere, but when the Earth attempts to re-radiate the light into space in the form of infrared (heat) radiation, the greenhouse gases trap it in the atmosphere. Greenhouse gases, such as carbon monoxide and methane, are produced by the burning of fossil fuels.

The answers from eri, campbelp2002, and aa are all correct. Zanti's claim that the sun will become a red giant in minutes is wrong. It will take millions of years--just the opposite of what he said.
Global warming is caused by the excess production of greenhouse gases. All one has to do is look at a graph of temperatures to see that long term natural temperature cycles cannot possible cause such a dramatic spike such as we have seen in the last 100 years and especially in the last 40.
BTW, it has nothing to do with the ozone. That's a different issue entirely.

Nope. The Sun is in a pretty stable phase right now. It's causing maybe 5-10% of the observed warming, no more. The article you cite is talking about what the Sun will do many millions of years from now. More here:

NO.
The real cause of global warming is the use of black asphalt paving everywhere, and black asphalt roof shingles on most all homes.
If we used white colored concrete or white impregnated asphalt for roads, highways, driveways, and parking lots, the temperatures in settled areas would be reduced by about twenty degrees in the daytime. The same situation holds true for home air conditioning. Power costs to run air conditioning systems would be significantly cut if people would only use white shingles for roofs on homes, offices and businesses.

No! The Sun is not changing to any significant extent. The transition of the Sun from consuming hydrogen to make Helium to a different fuel is not expected to happen for Billions of years. We are talking about changes that have happened in tens of years. We have been measuring the output of energy from the Sun and there has been no significant change.

No, the sun is not becoming a red star, it has too much hydrogen for that, but it is getting warmer. Science has shown us the sun has a normal 100,000 year cycle where there is cooling and warming. The martial polar spots have visibly melted in our lifetime, indicting we are going through a warming phase.

No. It is not. That has always been there even before it was discovered. Global warming is cause by humans and our effect on the Ozone Layer.

No. When the sun turns into a red giant, it will expand in a matter of minutes. It is not a slow process taking millions of years.

no, it has nothing to do with global warming, global warming is caused by humans by releasing CO2 emmisions into the atmosphere
