“I read somewhere that the sun’s getting hotter every year,”
said Tom genially. “It seems that pretty soon the earth’s going to fall into
the sun — or wait a minute — it’s just the opposite — the sun’s getting colder
every year.”

It's fairly obvious that the sun is moving away from us at a rapid speed, while simultaneously growing in size. Global warming occurs when its growth increases faster than its sped away from us, or sometimes when the speed remains constant but it has a bit of a "growth spurt".
ReplyDeleteSam - I agree, and soon we should be able to see right through an increasingly attenuated sun.
ReplyDeleteI suspect for most of us the question is purely academic.
ReplyDeleteDemetrius - yes, life is generally too short for these things to matter.
