How to comment in 120 to 150 words on climate change acclerating rise in sea levels ? Please answer this question

Answer 1

As humans emit heat-trapping gases like carbon dioxide, the planet warms, and over time consequences become more apparent. Some of the consequences we are familiar with – for instance, rising temperatures, melting ice, and rising sea levels. Scientists certainly want to know how much the Earth has changed, but we also want to know how fast the changes will be in the future to know what the next generations will experience.

One of the classic projections into the future is for sea level rise. It is expected that by the year 2100, the ocean levels will rise a few feet by the end of the century. This matters a lot because globally, 150 million people live within three feet of current ocean levels. We have built our modern infrastructure based on current ocean levels. What happens to peoples’ homes and infrastructure when the waters rise?

But projecting ocean levels into the future is not simple; we need good data that extends back decades to understand how fast the climate is changing. The classic way to measure ocean levels is by using tide gauges. These are placed just offshore, around the globe to get a sense of how the ocean levels are changing. The problem with tide gauges is they only measure water levels at their location, and their locations are always near shore.
