<human>:  Explain the causes and effects of global warming.
<bot>: Causes of global warming: The primary cause of global warming is the increased emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide into the Earth's atmosphere. These gases act as a blanket around the Earth, trapping heat and leading to an increase in the Earth's average temperature. Human activities like burning fossil fuels, intensive farming, and large-scale deforestation play a major role in the release of greenhouse gases. 2 Effects of global warming: The effects of global warming can be seen in many different ways. It can cause extreme weather events like floods, severe storms, and droughts. Animals and plants, particularly in the Arctic and other sensitive ecosystems, are also impacted by global warming. Warmer temperatures can also lead to the spread of human diseases and outbreaks of pests. In addition, rising sea levels are a direct result of global warming, as the polar ice caps are melting due to increased temperatures.
