According to a report from MSNBC, last May, the amount of carbon dioxide in Earth’s atmosphere surpassed the highest levels in human history. Emission measurements reached 400 parts per million, and some are angry that this amount of pollution continues to be pumped into the atmosphere. As of last month, industrial civilization has claimed another achievement: a record-breaking concentration of 400 ppm for three months in a row.
Data from the National Oceanic and Atmospheric Administration say that April, May, and June have all reached CO2 concentrations in excess of 400 ppm. This makes the past three months the first period of such a duration where human activity has contributed to such high levels of carbon dioxide.
The announcement comes in the midst of a full-on push by the White House for climate change mitigation. In early June, the Environmental Protection Agency revealed a draft regulation which would aim to cut power plant emissions by 30% before the end of 2030. The Obama administration is also working to expand protected ocean area, among other policy initiatives to slow down the pace of climate change.
