Take a Cool Guess—The Fun Quiz on Renewable Energy and Environmental Sustainability. Today’s Topic: Sea-Level Rise and Flooding

Question:  As a rule of thumb, how many additional people on Earth are subjected to flooding for each centimeter the ocean rises?

Answer: Can be found at Clean Energy Answers.

Relevance: As discussed here, the Greenland Ice Sheet is rapidly melting; from 1992 and 2018, 3.8 trillion tons of ice disappeared into the world’s oceans.  The findings published in a new study from NASA and the European Space Agency (ESA) forecast an approximate 3 to 5 inches (70 to 130 millimeters) of global sea level rise by 2100, which aligns with previous worst-case projections.

From the article:

Changes to the Greenland and Antarctic ice sheets are of considerable societal importance, as they directly impact global sea levels, which are a result of climate change. As glaciers and ice sheets melt, they add more water to the ocean. Increasing rates of global warming have accelerated Greenland’s ice mass loss from 25 billion tons per year in the 1990s to a current average of 234 billion tons per year. This means that Greenland’s ice is melting on average seven times faster today than it was at the beginning of the study period. The Greenland Ice Sheet holds enough water to raise the sea level by 24 feet (7.4 meters).
