Answer:
1. The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.
2.There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans and air flows in the atmosphere
3.The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.
4.The main sources of greenhouse gases due to human activity are: burning fossil fuels leading to higher carbon dioxide concentrations. farming and forestry — including land use change via agriculture and livestock. cement manufacture.
5. - Reduce, Reuse, Recycle
- Use Less Heat and Air Conditioning
-Use Less Hot Water
