hey how you all doing? Can anyone tell me 2 scenarios that could possibly lead to no overall change in GMST in this way. (1) The fraction of Earth's surface covered with ice and snow decreases while the albedo of the surface (which isn't covered by ice and snow) decreases. (2) The atmospheric CO2 concentration decreases while the solar constant increases. (3) The volcanic aerosol content in the atmosphere increases while the atmospheric H2O concentration decreases. (4)The volcanic aerosol content in the atmosphere decreases while the atmospheric CO2 concentration increases. (5)The albedo of the surface (which isn't covered by ice and snow) decreases while the fraction of Earth's surface covered with ice and snow increases.

hey guys, would just like to say hi. Im new here so please bear with me.The only way to start my thread is to be honest, so here goes. I have recently started a couse in biology. I now know that i jumped in the deep end and im drowning slowly. The frst course is science (book 1 global warming). And i have'nt got clue, having NO scientific knowledge whatsoever. Yes, i would be lying if i said i did'nt want answers, so i need serious help with understanding with the veiw to finding the answers, does that make sense? many thanx carl.
