The Keeling Curve is a daily record of global atmospheric carbon dioxide (CO2) concentration maintained by Scripps Institution of Oceanography at UC San Diego.
The concentration of CO2 in the atmosphere increases every year, and the rate of increase is accelerating.
The rise in CO2 concentrations is not yet slowing down. The American agency said that atmospheric carbon dioxide peaked in May at an average of more than 420 parts per million, "pushing the atmosphere further into territory not seen for millions of years."
We need to make more progress replacing fossil fuel combustion with renewables.
Without change, we face consequences such as continued global warming, more severe weather, including droughts, heat waves and floods.
For global temperature rise is to be halted, the accumulation of CO2 in the air needs not just to end, but go into reverse. For the Keeling Curve, this would involve a complete change in direction – rising more slowly at first, but then stopping and declining.
Renewable energy plays a central role to limit global warming and that is how Low Carbon is making a key contribution we can in the fight against climate change.
