Human: In the movie ‘Glaciers’, why did the ice melt? Assistant: 
The ice melted because of global warming. The Earth’s temperature has been rising over the past century, and it is expected to continue to rise in the coming decades. This warming trend is due to human activities such as the burning of fossil fuels, deforestation, and other activities that release greenhouse gases into the atmosphere. As a result, the ice caps are melting, and the sea level is rising.
