Take a Cool Guess—The Fun Quiz on Renewable Energy and Environmental Sustainability. Today’s Topic: Sea-Level Rise
Question: According to the National Academy of Sciences, which end of the antarctic (east or west), previously thought to be fairly stable, is now reported to be losing ice mass. This represents almost 40% of the total loss on the continent (which has caused 13.8 millimeters of sea level rise over the past 40 years).
Answer: Can be found at Clean Energy Answers.
Relevance: This side of the continent has 10 times more ice than the other half, and was long thought to be insulated from climate change because it rests on land, largely protected from warming ocean waters. A 2018 Nature paper estimated the region was actually gaining ice. If confirmed, these new results could dramatically reshape projections of sea level rise for the next century.
Craig,
Sea levels and Coastline changes caused by earth movements, erosion etc, are a very complex field of study, and only fractionally understood.
Sea levels have always been in a constant state of flux which is why attempting to claim any definite effects are attributable to any single reason is absurd.
Are sea levels rising ?
Yes, cry the GW/CC advocates and activists, that’s obvious since melting ice etc, will obviously increase the volume of the world’s oceans causing a loss of land area.
But where is the evidence? If the “bad science” is removed, (that is when a theory is conceived and then evidence is sought to confirm the theory, ignoring any contrary explanations) no evidence exists of any significant rise in sea levels due to polar melt.
Many low lying islands which should be underwater by now if the prediction of GW/CC advocate were accurate, have actually increased in land area and height !
The reasons for this phenomenon are largely little understood, while theories abound about the behavior of underwater volcanic activity and seabed compaction.
That’s the problem with ascribing simplistic predictions to complex issues.
Meanwhile, the coast of beachfront real estate keeps increasing !
