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.

In addition to other environmental impacts, these activities change the land surface and emit various substances to the atmosphere.

These in turn can influence both the amount of incoming energy and the amount of outgoing energy and can have both warming and cooling effects on the climate.

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.

Global warming can only be stopped by reducing global emissions of carbon dioxide from human fossil fuel combustion and industrial processes to zero, but even with zero emissions, the global temperature will remain essentially constant at its new warmer level.

Emissions of other substances that warm the climate must also be substantially reduced. Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators.Different factors operate on different time scales, and not all of those factors that have been responsible for changes in earth's climate in the distant past are relevant to contemporary climate change.Factors that cause climate change can be divided into two categories ­- those related to natural processes and those related to human activity.In addition to natural causes of climate change, changes internal to the climate system, such as variations.In ocean currents or atmospheric circulation, can also influence the climate for short periods of time.Of these, the two factors relevant on timescales of contemporary climate change are changes in volcanic activity and changes in solar radiation.In terms of the Earth's energy balance, these factors primarily influence the amount of incoming energy.Such climate change could have far-reaching and/or unpredictable environmental, social, and economic consequences.Carbon dioxide is the main cause of human-induced climate change.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.
