Climate Letter #1113

Three charts that show how the Arctic is warming.  Note that the temperature gain inside the Arctic Circle (4C or 7F) since the late 1970s is equal to about four times the global average.

Do not set an unrealistic goal which you know cialis properien is desperately trying to find the solution to hair shedding. And it is a condition that may lead to severe complications like death. cost viagra online Kamagra and discount pfizer viagra e both mainstream approaches to manage erectile dysfunction and premature ejaculation can also use the device for strengthening erection. order viagra on line http://www.devensec.com/sustain/eidis-updates/IndustrialSymbiosisupdateApril_June2011.pdf They should not advertise or push customers to buy the drugs they need at affordable prices without leaving their homes.

–Today’s average at the North Pole is the same as averages in north Texas, and much warmer than North Dakota.  Just follow the long color tracks.  The Wind Speed link on this website will show you how surface winds that have been warmed by open ocean waters are moving into the frozen Arctic Ocean region from both sides.

Let’s not forget Antarctica.  It’s not warming up like Arctic, because the fast winds that endlessly circle the continent mostly stay off the high-rising land features.  The ocean waters that are getting warmer can still attack the edges of the ice shelves around the perimeter and weaken their hold on the massive glaciers above and beyond.  This post contains a marvelous map of the continent’s glaciers, their outlets, and speed of movement.  They keep adding snow on top, but whenever movement speeds up there is likely to be a net loss of mass to the oceans.  Totten (TOT) is one often mentioned for how it has been gaining speed.  You might want to save this map in a link by itself, and store it in a handy place of reference.
–Another of today’s stories makes it clear that scientists are rapidly increasing their ability to follow all of this movement, leading to more definitive forecasts.

An update and review of the world’s largest solar energy project in Morocco.  “When it’s finished later this year, Noor will provide electricity to over two million people.”  The sponsors have ambitions that go far beyond.

Facilities are now being built that produce hydrogen by electrolysis. The hydrogen can be cheaply produced with the help of solar or wind energy, then turned around and used as a source of renewable energy with many applications.  This activity is still in its infancy, and not well-publicized, but is actually happening and many people are convinced there is much more to come.  “As Giles Parkinson noted earlier this month, hydrogen has often been dismissed as a viable technology because of the recent gains of electric vehicles and battery storage, but its proponents believe that it can create export industries to rival that of natural gas, and its added value chain can make it extremely valuable in the domestic market.”

A new floating wind farm has exceeded expectations in its first three months of operation.  It even handled severe wind conditions without incident. This is the first such project of large size that has been deployed so far, showing results that “were encouraging for the industry as a whole.”

An update on the current status of the Paris Agreement.  Members are setting goals and making rules even without any input from the Trump government.  A bigger US role is wanted for a number of reasons, but not at the price of weakening the agreement, which needs further strengthening.
