<![CDATA[This Morning’s Asthma Free Walk In 400 PPM CO2]]>Tom and Becky took me for a lovely walk this morning along the Mississippi River
In 1988, CO2 was 350 PPM and the Mississippi River was almost dry. James Hansen warned Congress that the droughts would only get worse as CO2 increased.
This is what the Mississippi River looks like at 400 PPM CO2.
