There is now compelling evidence to show that humanity’s impact on the Earth’s atmosphere, oceans and wildlife has pushed the world into a new geological epoch, according to a group of scientists.
The question of whether humans’ combined environmental impact has tipped the planet into an “anthropocene” – ending the current holocene which began around 12,000 years ago – will be put to the geological body that formally approves such time divisions later this year.
The new study provides one of the strongest cases yet that from the amount of concrete mankind uses in building to the amount of plastic rubbish dumped in the oceans, Earth has entered a new geological epoch.
“We could be looking here at a stepchange from one world to another that justifies being called an epoch,” said Dr Colin Waters, principal geologist at the British Geological Survey and an author on the study published in Science on Thursday.
“What this paper does is to say the changes are as big as those that happened at the end of the last ice age . This is a big deal.”
