Climate change is expected to have the most severe impact on water supplies.

Example of cause and effect of climate change. Causes of Climate Change. The earth over its 45 billion. Some gases in the Earths atmosphere act a.

The earth makes one full orbit around the sun every year. Causes of climate change - human and natural factors A natural function of the Earths atmosphere is to keep in some of the heat that is lost from the Earth. Moreover another cause that affects climate changes is the earths orbital changes.

More details about the effects of global warming. The effects of climate change span the physical environment ecosystems and human societies. Its reasonable to assume that changes in the Suns energy output would cause the climate to change since the Sun is the fundamental source of energy that drives our climate system.

Climate change is defined as a change in global or regional climate patterns in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels Climate change has happened as a cycle throughout history with ice ages occurring and then warming. Carbon dioxide is the largest single contributor to human-induced climate change. Temperature rise is accelerated or tempered by climate feedbacks such as loss of sunlight-reflecting snow and ice cover increased water vapour a greenhouse gas itself and changes to land and ocean carbon sinks.

Both human-made and natural factors contribute to climate change. Although water vapour absorbs heat it does not accumulate in the atmosphere in the same way as other greenhouse gases. For example a decrease in solar activity coupled with an increase in volcanic activity is thought to have helped trigger the Little Ice Age between approximately 1650 and 1850 when Greenland cooled from.

Causes of climate change Greenhouse gases. Include burning fossil fuels cutting down forests and developing land for farms cities and roads. Climate change and health Health effects risks food and water security infectious diseases and populations at risk.
