¥Assume that the Earth is warming.
¥Warming leads to more melting of ice
¥Less ice reduces EarthÕs albedo
¥Earth absorbs more sunlight
¥Earth becomes warmer melting more ice
¥
¥Works in the other direction as well:
–Cooling makes more ice which reflects
sunlight which makes Earth
colder which makes more ice
