Scientists agree that the earth has warmed during the last century and that human activities are the cause. The past four years (2015–2018), in fact, are the warmest since meteorological records started about 1880. The primary cause, the greenhouse effect, is an imbalance between the Earth’s retaining solar energy and reflecting it. These factors include burning fossil fuels that emit carbon dioxide, methane and other greenhouse gases into the atmosphere. Deforestation, the use of aerosols, for example, chlorofluorocarbons (CFCs), intensify this. Ozone is still another factor. In contrast, long-term climate changes occur across thousands of years as a result of orbital position. Our responsibility: Work together to change climate change. Recall the Kenyan proverb: “The Earth . . . was not given to us by our parents. It was lent to us by our children.”
