There has been scientific debate for more than ten years if the changes humans have been making to the planet actually comprise a new name-worthy geologic time period. A new study indicates that is indeed so.
From ThinkProgress.org contributor Alejandro Davila Fragoso on 1/7/16:
Waters and other authors of the study — which gathered data from multiple other studies — said the amount of data available identifies various so-called signatures that can be found worldwide in a similar time and scale. This makes the case for the Anthropocene and its proposed starting date compelling, some authors said.
“It’s the things like the novel materials we’ve seen in the last 60 years,” said Waters, a principal geologist at the British Geological Survey. “It’s the way that the atmospheric geochemistry, the CO2 and the methane (have) changed dramatically in the last 60 years. It’s the general contamination from nitrates and phosphates, heavy metals, all the things that we looked at seem to show a very dramatic change in the mid 20th century.”
