<human>:  What is the scientific evidence for global warming?
<bot>: The scientific evidence for global warming includes rising sea levels, melting glaciers, warming ocean temperatures, declining Arctic sea ice, and increasing atmospheric and oceanic temperatures. Additionally, more frequent and intense extreme weather events such as droughts, floods, and heatwaves have been observed due to global warming. The concentration of heat-trapping greenhouse gases in the atmosphere has been increasing since the Industrial Revolution, further contributing to global warming.
