Climate change is a real issue in the world and is something that should be taken very seriously. Our lives depend on nature and if we don’t take that seriously it can be an extreme danger to us.
Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years. Geological records show that there have been a number of large variations in Earth's climate. These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide. Changes in climate can affect food production, water availability, wildlife and human health. Weather conditions, such as storms, can damage infrastructure like roads, rail networks and buildings.
