Human Caused Climate Change:
Climate change is natural changes of earth's temperature over time. This rise in temperature is caused by the greenhouse gases: carbon dioxide, methane, water vapor, and ozone. These gases work together to trap heat in the atmosphere to keep earth from freezing. However, human caused climate is the dramatic rise in earth's temperature caused by burning fossil fuels. Fossil fuels are fossilized plants and microorganisms from thousands of years ago. These plants and microorganisms have massive amounts of carbon. When fossil fuels are burnt for energy and industries, they release the carbon built up inside them. This caused a massive and unnecessary buildup of carbon and other greenhouse gases in the atmosphere. This is caused a drastic rise in Earth's temperature. The Earth can't get higher then 2 degrees celsius, or the events will be catastrophic.

Why we need to prevent it:
Climate change is currently causing many natural disasters like hurricanes, tornadoes, flooding, and heat waves due to weather anomalies that is caused by climate change. Climate change is also causing ocean acidification, which is caused by the increased carbon supply in the ocean, as well sea level rise. This is making it hard for marine life to thrive. Arctic animals are also being impacted because the ice they live is rapidly melting. If the Earth gets above two degrees celsius Earth's sea level lines/coasts will experience massive sea level rise, risking coastal cities to be completely submerged.
