The document discusses climate change and its causes and impacts. It begins by defining weather and climate, then states that the planet is getting warmer due to the greenhouse effect trapping heat. It suggests this warming is being caused by human activities that release greenhouse gases like carbon dioxide and methane through processes like burning fossil fuels and cement production. This climate change is impacting various organisms, like causing sea turtle populations to become skewed in gender and reducing suitable habitat for polar bears. The document also notes ways climate change can influence weather patterns and events like hurricanes or the Winter Olympics through changes in temperature and precipitation levels.
