lush warm periods


Senior Member
Hello everyone,

From the book Thank You for Being Late by Thomas Friedman.

For most of the Earth’s 4.6-billion-year history, its climate was not very hospitable to human beings, as it oscillated between “punishing ice ages and lush warm periods” that “locked humanity into seminomadic lifestyles,” explained Johan Rockström, director of the Stockholm Resilience Centre, one of the world’s leading Earth scientists, and one of my teachers on all things climate.

Does lush imply that there were many green plants and grass in those warm periods?

Thank you.

    Yes, although lush applies to plants generally, not just green plants.

    Instead of many green plants and grass I would say lots of (green) plants and grass, i.e. you cannot say many grass.

    Lush, as an adjective, is very positive = succulent, growing in abundance and luxuriantly. This gives the idea of a moist atmosphere and/or plenty of rain/water that has greatly benefited the grass and other plants.
