Global Warming and Climate Change Global warming is predominantly a problem of too much carbon dioxide, chlorofluorocarbons and other industrial gases in the atmosphere.As human beings destroy forests, burn fossil fuels like coal, oil and natural gas, carbon accumulates and overloads our atmosphere; as a result glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is nearing extinction.
Climate change can also be caused by human activities, such as the burning of fossil fuels and the conversion of land for forestry and agriculture.
Since the beginning of the Industrial Revolution, these human influences on the climate system have increased substantially.
However, its long-term state and average temperature are regulated by the balance between incoming and outgoing energy, which determines the Earth's energy balance.
Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change.
The additional greenhouse gases in earth’s atmosphere have had a strong warming effect on earth’s climate.
Future emissions of greenhouse gases, particularly carbon dioxide, will determine how much more climate warming occurs.Carbon dioxide is the main cause of human-induced climate change. Other greenhouse gases, such as nitrous oxide, stay in the atmosphere for a long time. Small changes in the sun’s energy that reaches the earth can cause some climate change.But since the Industrial Revolution, adding greenhouse gases has been over 50 times more powerful than changes in the Sun's radiance.Human activity is the main cause of climate change.People burn fossil fuels and convert land from forests to agriculture.This natural internal climate variability is superimposed on the long-term forced climate change.The Earth's climate can be affected by natural factors that are external to the climate system, such as changes in volcanic activity, solar output, and the Earth's orbit around the Sun.Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events.The earth's climate is naturally variable on all time scales.The dominant product of fossil fuel combustion is carbon dioxide, a greenhouse gas.The overall effect of human activities since the Industrial Revolution has been a warming effect, driven primarily by emissions of carbon dioxide and enhanced by emissions of other greenhouse gases.
