I saw at one time a leaflet that asked people to come together in stopping climate change. It seems that many are not aware that the climate changes all the time and that the change is not stoppable. Climate changes, however, differ in their timing and magnitude and are a result of many factors, such as the distance between the sun and the equator, which contributes to the heat budget of the Earth, and the difference in the temperature of the equator from that of the cooler poles due to deviations in Earth's orbit, or variations in solar radiation.
