CAUSE
One question. One truth.
“Why is sea level rising?”
Sea level is rising primarily due to thermal expansion of ocean water caused by global warming, which increases ocean temperatures and causes water to expand, combined with accelerated melting of land-based ice sheets and glaciers adding more water to the oceans.
