Sleeping giant?

The quotation is portrayed at the very end of the 1970 film Tora! Tora! Tora! as:

I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.

The quotation is also featured in the 2001 film Pearl Harbor.

Although the quotation may well have encapsulated many of his real feelings about the attack, there is no printed evidence to prove Yamamoto made this statement or wrote it down.

2. Aside from getting a better handle on how methane might affect our future, scientists are also considering how we could prevent its release. One innovative approach is a scientific reserve in northeast Siberia known as Pleistocene Park, created by Sergey Zimov, director of the Northeast Science Station in Cherskii, Russia. In a bid to keep the permafrost frozen, Zimov is working to reintroduce animals that resemble Pleistocene megafauna and to restore the ancient steppe-grassland ecosystem. Steppe vegetation reflects more sunlight than the now-dominant forests and wetlands, reducing summer heat. In addition, animals trample down the snow when they forage, and the resulting denser snowpack provides greater insulation, allowing the ground below it to freeze much deeper in the wintertime, explains Zimov. "All we need to do to turn the current low-productivity ecosystems into high-productivity steppe is to bring in high enough densities of animals and then let them transform the ecosystem themselves," he says. The north Siberian plains contain some 500 billion tonnes of carbon stored as permafrost, so if they were to melt, says Zimov, "all this carbon would quickly be transformed to greenhouse gases." So far, Zimov and his colleagues have introduced horses, reindeer and moose, and they are hoping to bring in musk oxen, mountain goats and bison in the near future.
