Leonardo DiCaprio’s “Before The Flood”

It should perhaps be called “During The Flood” because anthropogenic change is already starting to flood parts of our planet. And giving anyone the sense that climate disaster is out there in the future somewhere instead of right here, right now is probably a bad idea. But credit to Leo for fighting the good fight and pushing on climate issues with persistence and sincerity.

I haven’t seen this new doc yet, but the full version popped up on YouTube, courtesy of National Geographic. So here it is:

The Relentless Rise Of CO2 Concentrations

Despite the global economic stagnation, in 2012 the amount of carbon dioxide in the atmosphere increased by 2.67 part per million, the second highest jump since levels were first measured in 1959:

 The new data, collected in Mauna Loa, Hawaii, suggests that levels of heat-trapping CO2 are now just under 395 parts per million (ppm) and could hit 400 ppm within two years, according to the National Oceanic and Atmospheric Administration (NOAA). The one-year increase was second only to 1998, when CO2 concentrations jumped by 2.84 parts per million; pre-industrial atmospheric concentrations of CO2 were 280 ppm.

Just one more data point which says 1) we are almost certainly in for a global temperature increase that exceeds the 3.6 degrees F (2 degrees C) threshold that scientists consider dangerous; and 2) we could see 4.5 degrees F increases within decades.

I’d say that calls for a paradigm shift in human thinking and behavior. Who’s in?
