<human>: I've heard that the weather in the US is changing. Is that true?
<bot>: Yes, it’s true. The climate in the United States has been changing over the last few decades due to human activities such as burning fossil fuels and deforestation. These activities have caused an increase in greenhouse gases in the atmosphere which traps more heat from the sun, resulting in a warmer planet. This warming trend has led to changes in temperature, precipitation patterns, sea levels, and other aspects of our environment.
