Negli ultimi mesi si parla poco del progetto KUN-24AP , la portacontainer cinese alimentata da un reattore al torio . Eppure, dietro a quella sigla tecnica si intravede una mossa strategica capace di cambiare la logistica globale. Non è solo ingegneria navale: è una revisione delle regole fisiche che tengono insieme il commercio mondiale. 1. L’equazione che la Cina vuole risolvere Pechino possiede enormi riserve di torio, sottoprodotto dell’estrazione delle terre rare . Mentre in Occidente si discute ancora di uranio e rinnovabili intermittenti, nel deserto del Gobi — a Wuwei — i reattori a sali fusi sono già in fase sperimentale. Portare quella tecnologia in mare significa sciogliere uno dei nodi strutturali del trasporto globale: la dipendenza dal petrolio . Oggi ogni viaggio è ostaggio del prezzo del Brent e dei choke point geografici: Malacca , Suez , Hormuz . Sono le vulnerabilità che gli Stati Uniti controllano e che la Cina subisce. Una nave che non ha bisogno di r...
Contrary to the so-called “consensus,” the planet’s climate is not warming, saysDavid Archibald, an Australian scientist and visiting fellow at the The Institute of World Politics (IWP) in Washington, D.C.
“The temperature of the planet is the same as it was 30 years ago,” said Archibald. “The IPCC models have failed.”
While temperatures have increased less than one degree Celsius (yes, less than 1 degree) in the last 150 years, that rise is unremarkable compared to previous increases in earth’s history, said Archibald on Wednesday. That rise came about because “the Sun was more active in the second half of the 20th century than it had been in the previous 8,000 years.”
Even with the higher solar activity, that small amount of warming is nothing new.
Temperature spikes have occurred for hundreds of thousands of years and were slightly higher in the Roman Empire and Medieval periods, according to a Swedish study and data from ice cores in Vostok, Antarctica, said Archibald.
In fact, it has been warmer than today for MOST of the past 10,000 years, says Dr. Don Easterbrook, Professor of Geology at Western Washington University.
Created by Cuffy and Clow in 1997, and based on Greenland ice core records, this chart shows global temperatures for the past 15,000 years.
Sometimes severe cooling comes out of the blue
Now, solar activity suggests that global temperatures will fall 2 to 3 degrees Celsius by 2040, said Archibald. “And sometimes severe cooling comes out of the blue.”
That could wreak havoc on the world’s food supply by potentially reducing global grain production by 400 million tonnes—mirroring the skyrocketing crop costs and 200,000 European deaths sparked by the 1816 eruption of Mt. Tambora in Indonesia.

Archibald, who is credited as the first scientist to develop a method for using solar sunspot cycles to predict temperatures, also predicts that “sea level will start falling again.”Where will that moisture go? It will start accumulating on land as ice, just as I have been predicting.
