Joshua Kelly, Meteorology Correspondent Redorbit.com If you recall back in the year 2000 we were being filled with this information of “global warming” occurring at record setting levels. However, did you also know that in 2009 there were reports of the glaciers in Montana gaining ground and expanding snow cover? So how is it possible that we are going into global warming and then magically just as of recently we now are being told that it´s “climate change.”...

Researchers at the California Institute of Technology (Caltech) suggest that the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of methane and ethane lakes over the northern and southern polar regions of the planet's largest moon, Titan. On Earth, similar "astronomical forcing" of climate drives ice-age cycles. A paper describing the theory appears in the November 29th advance online edition of Nature Geoscience. As revealed by Synthetic...

Scientists are now making an alarming claim that the earth is on the brink of entering another Ice Age that could last the next 100,000 years. They believe a 12,000-year warming period is currently winding down. They say ice cores, ocean sediment cores, the geologic record, and studies of ancient plant and animal populations all demonstrate a regular cyclic pattern of Ice Age patterns, separated by intervening warm interglacials, each lasting about 12,000 years. Experts point out that most...

New technologies are enabling scientists to determine precisely the extent and causes of Earth's short-term wobbling. Like a spinning top, Earth wobbles as it rotates on its axis. In fact, it displays many different wobbling motions, ranging in period from a few minutes to billions of years. Some of these are well studied, like the Chandler wobble of 433 days and the annual wobble, which together can tilt Earth's axis up to 10 meters [30 feet] from its nominal center. Earth's irregular,...

Tilt is a 100,000-year planetary pacemaker Woods Hole -- Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds that these glacial cycles are paced by variations in the tilt of Earth's axis, and that glaciations end when Earth's tilt is large. With more than 30 explanations proposed for these glacial cycles, researchers at the Woods Hole...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
