2016 was the Hottest Year on Record

2016 was the hottest year on record and the third consecutive year of record temperatures, according to climate scientists.   Furthermore, the rate of temperature change seems to be accelerating.

Nearly all climate models conclude that the most likely cause of global warming is rising levels of atmospheric CO2 levels brought about by the burning of fossil fuels.  And yet, so far not much has been done about it.  The problem (and perhaps the reason that climate deniers continue to deny that global warming is even happening) is that curbing future increases in CO2 will not be easy or cheap as long as we continue to depend on fossil fuels for most of our energy needs.

And so Earth will probably continue to warm up.  Sigh.
