These gases such as carbon dioxide and methane warm and alter the global climate which causes environmental changes to occur that can harm peoples health and well-being. C limate change may cause weather patterns to be less predictable. Global Regions WHO Regional websites Africa Americas.
Climate change involves longer-term trends such as shifts toward warmer wetter or drier conditions. Climate Change Climate Change is the defining issue of our time and we are at a defining moment. Climate change involves significant changes in average conditionssuch as temperature precipitation wind patterns and other aspects of climatethat occur over years decades centuries or longer.
Climate change is generally defined as a significant variation of average weather conditionssay conditions becoming warmer wetter or drierover several decades or more. Our planets climate is also affected by volcanic activity and changes in how much energy from the sun hits the earth. However the average rate of increase since 1981 018C 032F has been more than twice that rate.
Learn how we protect them. Protecting the Redwood Forests of the Santa Cruz Mountains. The rapid climate change we are now seeing is caused by humans using oil gas and coal for their homes factories and transport.

While we know that global climate has changed since before recorded human history many pinpoint the source. Climate change is a shift in those average conditions.
One way that we know that the current warming is caused by human activity is because we are currently in a cycle that should be cooling the planet.
