Evening GW and all! Im new on hrer but have been reading this subject/thread on and off for 3 or so years! I tend to hop around on different threads but do find this subject very interesting. Im a novice so if my questions/suggestions seem so 1990s pls be understanding! Myself i tend to think that the sun is the main player from what ive read/learnt but thats not to say that manmade warming is not present. RE ice retension/expansion, i know it seems coy to say so but i dont think records go back long enough to be pro/con, and i feel its time we do need to get closer to understanding the prblems/solutions!
