Climate-change sceptics sometimes argue that there is no cause for concern from global warming because in the past 2000 years the world has already gone through several natural cycles of warming and cooling from which it has always rebounded on its own.
However, new research has found that rather than being global events, these natural cycles were actually regional changes that never affected more than part of the globe at any one time.
Furthermore, these warming and cooling patterns didn’t occur anywhere close to simultaneously in the parts of the world they did affect.

An installation at the Brooklyn Botanic Garden ponders the sounds made by plants.
What does a plant sound like?
This is the sound of corn growing.
It’s also part of an art installation on display at the Brooklyn Botanic Garden in New York through October. This veggie-lullaby plays from large, yellow horns planted with corn seeds in a plot of soil. As the seedlings grow, their sounds will also be recorded.
“They’re communicating to each other,” says Adrienne Adar, the artist who designed this installation, “Sonic Succulents: Plant Sounds and Vibrations,” on display until Oct. 27. “We are not their audience.”
