Fifty-five million years ago the North Pole was an ice-free zone with tropical temperatures, according to research. A sediment core excavated from 400m (1,300ft) below the seabed of the Arctic Ocean has enabled scientists to delve far back into the region’s past.

Why are tropical rainforests?

Tropical rainforests occur in regions of the tropics where temperatures are always high and where rainfall exceeds about 1,800 to 2,500 mm (about 70 to 100 inches) annually and occurs fairly evenly throughout the year.

What are the main features of temperate rainforest?

characteristics. Temperate rainforests filled with evergreen and laurel trees are lower and less dense than other kinds of rainforests because the climate is more equable, with a moderate temperature range and well-distributed annual rainfall.

Was the Artic ever green?

Summary: Recent analysis of ancient DNA gathered from lake beds in the Arctic may not only be a glimpse of the past but a snapshot of our potential future. Imagine not a white, but a green Arctic, with woody shrubs as far north as the Canadian coast of the Arctic Ocean.

Did the Arctic used to have trees?

“Go back 100 million years ago and Antarctica was covered in lush rainforests similar to those that exist in New Zealand today,” said Dr Vanessa Bowman who works with Francis at the University of Leeds. “We commonly find whole fossilised logs that must have come from really big trees.”

Is the Amazon a tropical rainforest?

Not only does the Amazon encompass the single largest remaining tropical rainforest in the world, it also houses at least 10% of the world’s known biodiversity, including endemic and endangered flora and fauna, and its river accounts for 15-16% of the world’s total river discharge into the oceans.
