What I did:

I came across an interesting article on the rise of sea levels due to climate change.

What I learnt:

1. Scientists first realised that sea levels were on the rise during the early 20th Century
2. Tide gauges are instruments along coastlines that measure sea level. Reliable tide gauge data existed for about 100 years, and during that time, the sea level was rising. Now, tide gauge data is considered unreliable.
3. Thermal expansion through warmer ocean waters was the largest contributor to global sea level rise over the past century.
4. There might be a total of 2m of sea level rise by 2100

Summary:

This article is about the causes of the rise in sea level and how it can be prevented.
