Has climate change affected marine life richness? Here’s what the latest study says

The total number of species living in the marine world has halved in the last 40 years as climate change has increased the sea surface temperatures by nearly 0.2 degree Celsius, showed a recent study published in the Proceedings of the National Academy of Sciences.

Revealing a correlation between the decline of species and an increase in temperature, the study noted factors like overfishing have also caused a major impact.

The researchers also stated that there has been a slight fall in species richness at the equator.
