How Climate Change Affects Life on Earth

"Climate" is the average of the weather conditions at a given point on the Earth. Typically, climate is expressed in terms of expected temperature, precipitation, and wind conditions based on historical observations. Earth's climate is always changing and we used to call it climate change. Climate change is a significant change in climate, air temperature, rainfall ranging from tens of years to millions of years. Climate change refers to changes in temperature and long-term weather patterns. The world is now about 1.1C warmer than it was in the 19th Century and the amount of CO2 in the atmosphere has risen by 50%.
