claim: “The IPCC reports also don’t fully account for the albedo effect ( less ice means less reflected and more absorbed sunlight, hence more warming ); more cloud cover ( which traps heat ); or the dieback of forests and other flora ( which extract carbon from the atmosphere ).
evidence: This has been a concern since arctic ice and snow has been melting at higher rates due to higher temperatures, creating regions in the arctic that are notably darker ( being water or ground which is darker color ) and reflects less heat back into space.
