Detailed explanation-1: -Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few.
Detailed explanation-2: -Which of the following is a potential impact of global warming on thermohaline circulation: The increased temperature of water masses would cause these currents to flow faster given the higher kinetic energy of the water molecules.
Detailed explanation-3: -Global warming could potentially cause a thermohaline circulation shutdown and subsequent regional cooling, but because Earth will continue to warm as a result of greenhouse gas emissions, it would not produce another Ice Age.
Detailed explanation-4: -Thermohaline circulation plays an important role in supplying heat to the polar regions. Therefore, it influences the rate of sea ice formation near the poles, which in turn affects other aspects of the climate system (such as the albedo, and thus solar heating, at high latitudes).
