Are sunlight and heat from the Sun equivalent?

Steven Hutchinson  asked the Naked Scientists:
   
Hello,

I am a researcher of Cognitive Psychology at the University of Maine in the US but today I have a physics question. I understand that when we are seeing the sun we are actually seeing the light from the sun about 8 or so minutes previously because the distance from earth is so great.

Are the sunlight and heat from the sun equivalent? In other words, if the sun were to suddenly expire, would we have no notice of an effect for around 8 minutes, or would a freezing effect be much quicker?

Thank you,

Steve

What do you think?
