A new milestone: Carbon dioxide levels surpass 400 parts per million globallyAnother month, another carbon dioxide record. This time the record extends beyond the rocky slopes of Mauna Loa, Hawaii, home to the most storied carbon dioxide record, and includes 39 other sites around the globe to paint a troubling picture of a greenhouse gas rise with no signs of slowing down.
This level is suppose to fall when plants in the northern hemisphere start to bloom and take it out of the air. However if something doesn't change one day the plants will just be taking it down to 400ppm that is if they are still there. We are slowly killing this planet and ultimately ourselves.
