400 ppm

Too Much Carbon

Mauna Loa observatory carbon dioxide readings over time
 ~ Atmospheric carbon is now higher than it has been in 3 million years.
The last time CO2 reached the symbolic milestone of 400 parts per million in the atmosphere - in the Pliocene era - temperatures rose by between 3 and 4 degrees and sea levels were between five and 40 metres higher than today.
Climate change is a slow-motion calamity, but also an economic opportunity for those who seek profit. Might be a good time to start businesses building seawalls, boats, or snorkels.
