The chart shows changes in sea level from 1995 to 2013. According to the chart, sea levels rose at an average annual rate of 3.2
MariettaO [177]

Answer:

Did the global surface temperature increase steadily from 1995 to 2013?

Did sea ice extent in polar regions reduce because of melting from 1995 to 2013?

Explanation:

Only two questions are directly related to global warnings increasing sea levels:

  • Did the global surface temperature increase steadily from 1995 to 2013? Increasing temperature of the Earth's surface is actually what warming means.
  • Did sea ice extent in polar regions reduce because of melting from 1995 to 2013? If the polar ice melts then the sea levels will rise.

The other three questions were about the negative effects of rising sea levels, but not what could cause them.
