“Carbon Dioxide Levels Just Hit Their Highest Point In 800,000 Years”

The concentration of carbon dioxide, the greenhouse gas that drives climate change, hit 402 parts per million this week — the highest level recorded in at least 800,000 years.

The recordings came from the National Oceanic and Atmospheric Association’s Mauna Loa Observatory in Hawaii, which marked another ominous milestone last May when the 400 ppm threshold was crossed for the first time in recorded history.

It’s not just the level that counts, its the rate of change. This is what was said about the rate of change:

Carbon dioxide (CO2) levels spike every spring but this year the threshold was crossed in March, two months earlier than last year. In fact, it’s happening “at faster rates virtually every decade,” according to James Butler, Director of NOAA’s Global Monitoring Division, a trend that “is consistent with rising fossil fuel emissions.”
