WebPhysical causes of climate change. Physical causes of global warming and cooling include:. Volcanic eruptions - large amounts of volcanic dust in the atmosphere shield the Earth from the sun, lowering the global temperature. For example, the eruption of Mount Pinatubo in 1991 caused a dip in global temperatures WebCooling Curves Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.
