CO2 has been breaching the 400ppm threshold for well over a year and just a few days ago, it was measured at NOAA’s Mauna Loa Earth System Research Laboratory at just over 407ppm. This is not good news at all.
The last time the earth had this level of CO2 in the atmosphere, our human ancestor was Pierolapithecus catalaunicus (a creature who lived around 13 million years ago pictured to the left), and sea level was about 100 feet higher than it is today.
It would be nice if our political candidates from all parties were debating the best solutions. Yet we are stuck with an entire political party who refuses to accept the science. We have to be informed and vocal and we have to hold our political leaders accountable for their ignorance of facts.
