WARMEST OCTOBER RECORDED SINCE 1880
The global average for land temperatures in October were the warmest since records began in 1880, reports the
NCDC/NOAA website. The average for land was up 1.12 degrees Celsius on the 1961-1990 base average.
The global average for land plus ocean was the second warmest on record. For land in the southern hemisphere it was the second warmest, for land in the northern hemisphere it was the third hemisphere.
The stratosphere, which trends downward as the surface trends upward, recorded the 3rd coolest temperature.

GAIA ON THE ROCKS
Minerals have evolved too, reports ScienceDaily.
Two-thirds of the over 4000 minerals on Earth owe their existence, directly or indirectly, to living organisms--which of course owe their existence to them, and so on.

COATING A HUGE BOOST FOR SOLAR-CELLS
A new nano coating for silicon solar cells boosts their absorption of sunlight from a maximum of 67.4% to a massive 96.21%, thus giving near-perfect absorption, right across the entire spectrum of sunlight. Even better, they function at that high level no matter what angle the light is coming from. That means static panels will no longer be less efficient than the ones that track the sun. Details in ScienceDaily.
