#241 Warming Oceans

The impacts of global warming on oceans are significant. One reason sea levels are uneven is that prevailing [1] drive ocean currents, distributing water in complex patterns. Water, like land, absorbs heat unevenly, which means [2] temperature also becomes uneven across regions. Sea levels of hotter waters rise more clearly because larger [3] is needed when water expands with heat. In addition, melting ice from icebergs helps to [4] sea levels even further, worsening the effects of climate change.
