No Laughing Matter

Not funny!      (Public Domain)

Greenhouse gases consist mainly of carbon dioxide, but also significantly of nitrous oxide (aka "laughing gas") and methane (aka "bovine gas").  They are collectively at a record high, despite the 2015 Paris agreement.

Carbon dioxide is a byproduct of the industrial revolution.  Nitrous oxide and methane are byproducts of unsustainable agricultural practices.

Atmospheric levels of carbon dioxide and methane have approximately doubled since

pre-industrial times, and levels of nitrous oxide have risen by 23 percent.  The World

Meteorological Organization reports that there is “no sign of a slowdown, let alone a decline" in these trends.
