Congratulations. ‘Murica, congratulations world!

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.

So many of us have done our part…but some have done quite a bit more than others.

Now let’s go have a nice glass of tap water…oops, sorry West Virginia.
