Carbon Dioxide Levels Reach All-Time High – Not Good

The concentration carbon dioxide continues to rise – not good news for the planet.  Carbon dioxide is the most abundant greenhouse gas – it traps heat.  More carbon dioxide in the air means more heat for the planet. See @SteveBowenWx tweet below.


CO2 concentration at the Mauna Loa Observatory reached a daily record of 421.21 Parts Per Million (PPM) on April 3. This is the first time in the recent measured record that PPM has topped 420 PPM. This map shows peak PPM values per year dating to the 1970s. Notice a trend?
