{7} Our Global Heat and Moisture Distribution Engine, visualized


Before I climb back into the mud pit, I want to share this installment of "Appreciating our Global Heat and Moisture Distribution Engine.  This time I feature four short videos produced by NASA Goddard that do a wonderful job of visualizing various facets of our planet's geophysical reality.  Using state of the art computer graphics based on actual satellite observations they visualize how these varied components seamlessly integrate with each other to create the wonderful planet that we were born into and the climate system we depend on for everything.

The first one is "Dynamic Earth" a 4.5 minute tour starting with our sun and finishing in our oceans, fascinating presentation, (as are all of these YouTube videos).  Then, "The Ocean: A Driving Force for Weather and Climate" is a 6 minutes long grand tour of the oceans.  Following that, the 3 minute "Aquarius: One Year Observing the Salty Seas - Ocean Salinity & Climate" presents the culmination of Aquarius Satellites first full year of data collection.  Finishing with an excellent 6 minute review of "Earth's Water Cycle."  

These visualizations are packed with satellite data and do a wonderfully job rendered our planet as a whole, set against the frigid void of space.  This place we call home is special, nothing else like it in the universe, it's worth getting to know and love and protect.

A study in miscommunication - increasing Antarctic ice extent (is no) mystery!


While culling through YouTube videos for a project, I came across a NASA Goddard video that presented a text book example of a well meaning, but overly cautious scientist whose's awkward wording and omissions leads to more confusion than clarity.  It also highlighted one of my pet peeves - the lack of a coherent and memorable narrative to serve as a skeleton upon which to drape the many varied bits and pieces of information being presented.  
(Well look at what I just discovered!  Seems that fraudster and PR spinmeister Lord 1000Folly, Monckton's YouTube clone (who's been flooding YouTube with maliciously fabricated misrepresentations of climate science), also discovered this example of NASA's communication failings and does he have a field-day mocking scientists based on manipulating this very video's gross omissions: "NASA - The Mystery of Antarctic Cooling" (1/26/16) no I'm not linking to it.   2/17/16,1:45 PM)

A unifying concept, such as "Plate Tectonics" which created a real mental visualizing tool onto which the disparate bits and pieces of geologic knowledge fit seamlessly and became a comprehendible whole.  Perhaps a concept along the lines of our "Global Heat and Moisture Distribution Engine" subtitled "It's The Atmospheric Insulation Silly."  

In any event, this quote at 0:55 set me off. - Speaker: "The increase that we're seeing in the Antarctic ice extent is a little bit of a mystery…" 

Poor phrasing indeed.  Particularly since he never brought it back to explaining how scientists have been uncovering the various geophysical phenomena that have driven the increasing sea ice and solved the one time mystery.

Not confronting that meme and explaining why sea ice has been increasing, they reinforce what an unschooled person might assume and what the contrarian PR machine keeps feeding people.  Why, I wonder?  After all, it is a pretty clear and straightforward story.

I follow the short video in question by highlighting the pieces of information I'm familiar with; information that offers a coherent physical explanation for why all that extra sea ice has been forming, and why it's part and parcel of global warming's cascading consequences.  Items that were unjustifiably omitted from the video but that could have been included.  For supporting evidence I link to various splendid short videos and some articles that provide further details to this aspect of our climate engine.
