Climate Letter #1266

A wonderful new tool for checking global temperature increases is now available.  I have not yet figured out the best way to use it, but the information is just fantastic.  A quick check of land and ocean grid blocks shows how great the differences are, even when comparisons are made side by side.  Give it a try and look for all kinds of things.

How global warming is causing the destabilization of mountain slopes.  We often read about specific events and their great devastation.  Here Bob Berwyn, writing for Inside Climate News, has put together a story that has complete perspective on what is going on and what it means for the future.  “For us it’s very important to know if climate change has an impact on rainfall, because that has the most influence on landslides and debris flows…..Climate change will increase the magnitude, not only the frequency, of these events.”

Some interesting new research about the unusual importance of the Southern Ocean in determining the global climate.  This ocean absorbs more than its fair share of the CO2 that humans emit but does not stay in the atmosphere, which is around half of what we emit.  The same ocean ends up with more than its share of the energy radiation generated by all of the extra greenhouse gases we have added to the atmosphere and which is then converted to heat that gets stored away by all of the oceans, some of it at depth and some at the surface.  As ocean surfaces grow warmer all over the globe they have a tendency to absorb less CO2, which allows more of what we emit to remain in the atmosphere.  Plus giving a big boost to rainfall extremes.
–On the other hand the Southern Ocean is also known for its ability to vent large amounts of CO2 into the atmosphere in certain situations when there is an extraordinary upwelling of deep cold water that is rich in CO2 that had been absorbed in an earlier era.  Some other recent research explained how that phenomenon helped to bring us off the bottom part of the last ice age, for example.

Tesla’s big battery for utility-scale power storage has passed every test so far.  Less than a year after being installed at a wind farm in Australia it is already making money for its owners.  Better yet, “Ten months on from its installation, the Tesla big battery has emphatically proven its worth – faster, quicker, more accurate, more reliable and more flexible than even the market operator thought possible.”  That should speed up the transition to renewables in the power sector all over the globe.  (But don’t overlook the next story.)

A new brand of zinc-air battery, costing about half as much to produce as lithium-ion, has been thoroughly tested for six years and is said to be ready for the next step of deployment (Yale e360, based on a report in the New York Times).  This looks like something serious that will be following right on the heels of Tesla.
–Here is the press release from the Chinese company that developed the technology and holds over 100 patents.  It is lengthy but worth reading.  The very last line—“By breaching the manufacturing barrier of $100 kWh, we can electrify the world anywhere everywhere.”  That might turn out to be true!  Keep an eye on it.
