Warming Earth
Do you hear unusual weather reports on the news lately? Unexpected weather events seem to happen more often than before. There is a lot of news about heatwaves, floods, droughts, and typhoons around the world. Reporters say they are because of climate change. But what is climate change?
Climate change refers to the long-term changes in Earth’s temperature and weather patterns. Throughout history, Earth has had both warming and cooling periods. And it is going through a global warming period now.
What is climate change?
Today’s global warming is happening too fast. And sadly, it is mainly caused by human activities. For example, the cars we drive and machines we use release greenhouse gases into the air. These greenhouse gases trap heat and speed up global warming. As temperatures go up, glaciers melt and sea levels rise. This puts coastal cities in danger of flooding.
Climate change is a serious problem for all areas of life. It affects ecosystems, agriculture, wildlife, and so much more. So, we must all work together to reduce greenhouse gases and fight global warming. Check Reading Fluency
