Climate Letter #815

The North Pole today, viewed in the Climate Reanalyzer.  What I see is an average of 32F (0C) for today’s temperature, about the same as northern Iowa, and that is in spite of months of 24-hour darkness.  The anomaly reading on a different link that shows 36F has to be corrected because the reality is somewhere off the chart, as high as 45 or 50.  The globe as a whole, by the way, shows an anomaly today of just 0.42C, or less than 1F, which is a bit on the cool side (baseline 1979-2000).

Massive burning of wood pellets for heating purposes in Europe is strongly criticized.  This report digs deeply into  issues like policy loopholes and carbon accounting trickery that are involved.  The US is affected by growing deforestation because of the high export demand.  As expected, American forestry companies treat this matter in the same denialist way as do the fossil fuel companies.

Many California forests are failing to regrow after intense wildfires.  The loss of too many mature seed trees is a primary reason.  The warmer and drier climate causes some areas to be burned repeatedly.  In the end forests can easily be replaced by shrub and grass lands, with a net loss of carbon to the atmosphere.

How corporate America is moving toward renewable energy.  The top three buyers are Amazon, Microsoft and Google.  They currently prefer wind over solar because of the cost advantage, but that could soon be changing as solar costs are falling more rapidly.  Many large companies that would stand to gain by moving to renewables have not yet done so simply for reason of lack of internal experience and confidence, which is also likely to change.
