While there is a broad consensus among scientists that global warming and resultant climate change are real, it is not accurate to say there is total unanimity. The expectation that sea levels will rise significantly is a well-documented consequence of global warming due to the melting of ice caps and thermal expansion of seawater. The average global surface temperature has increased, but not by as much as five degrees Celsius since the late 1800s; the actual increase is closer to 1 degree Celsius. Global warming is primarily caused by human activities, especially the emission of greenhouse gases like carbon dioxide, rather than volcanic action.
