What is Global Warming ?













Global warming is when the Earth heats up. It happens when greenhouse gases like carbon dioxide, water vapor, nitrous oxide, and methane trap heat and light from the Sun in the Earth’s atmosphere, which increases the temperature.











The average temperature in the atmosphere mass increased by 0.74 - 0.18 degrees Celsius during the last century. According to the study prepared by the Intergovernmental Panel on Climate Change, and notes that the increase in the average global temperature has been due to the increase in greenhouse gas concentrations. This has led to high temperatures unprecedented on Earth.
The other phenomena responsible for global warming is solar eruptions and these changes include an increase in temperature which will cause climate change and extreme weather conditions such as sea level rise, the change in the quantity of above-average rainfall, and the melting of ice caps in the polar regions, glaciers, storms and hurricanes. Global warming will increase the spread of diseases as there will be droughts and floods, coral bleaching and forest fires and soon.
