This tilted axis is why Earth has seasons, and it creates the planet's three major climactic zones: the polar regions in the Arctic and Antarctic, the middle temperate zones, and the tropical regions.

Given the large causalities and economic losses, it's been frustrating that predicting these events with global computer models is more difficult outside the Earth's tropical zone than within it.

The eventual tropical dead zone impacted the distributions of both marine and terrestrial organisms throughout Earth. Some organisms, including sharks, horseshoe crabs, and temnospondyls ...

This 'tropical dead zone' drastically impacted the distributions of both marine and terrestrial organisms. Co-author Dr Suresh Singh said: "We collected data on 100 temnospondyls that lived ...
