Which statement best explains why methane is both potent and short-lived? Low reactivity and low emissions No chemical reactivity Strong radiative forcing but rapid atmospheric removal High reactivity but weak radiative forcing 2. Snow cover influences climate primarily through ___________ Wind circulation Atmospheric pressure Rainfall processes Albedo effect 3. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Amplifies warming through reduced albedo and increased heat absorption Reduces CO₂ emissions Stabilizes ocean currents Increases precipitation 4.
