Obama believes that troubled black teenagers should carry guns, apparently so that they don’t hurt their hands beating senior citizens and neighborhood watch people.
I just ask people to consider if Trayvon Martin was of age and armed, could he have stood his ground on that sidewalk?

’71 Valley Quake a Brush With Catastrophe
SAN FERNANDO — It was not only the biggest quake in San Fernando Valley history at the time, but it was the first strong one in the Valley since 1893.
The San Fernando quake, in fact, could have been a catastrophe instead of just a costly disaster. That conclusion arises from its most striking episode: the near-collapse of the lower dam at the Van Norman reservoir.
The 1,100-foot dam held 3.6 billion gallons of water on the morning of Feb. 9, 1971, but it was only half full; the water level was 36 feet below the lip.
The top 30 feet of the edifice crumbled, leaving the water only six feet from the top and fresh chunks of earth falling off with each aftershock.
A year to the day before the quake, the dam held 6.5 billion gallons of water, and its level was eight to 10 feet higher than the level to which the top of the dam slumped in the quake. Engineers recognized that had such a vast quantity of water spilled over the top, the entire dam would have quickly been washed away.
Later, a UCLA study estimated that collapse of the dam would have brought flooding that could have killed between 71,600 and 123,400 people.

The last two days have seen increases in Arctic sea ice area.
Natural fires occurred approximately every 5-15 years in sequoia groves. Sequoias thrive in a forest with frequent fire which opens the canopy for this sun-loving tree and clears the ground so there tiny seeds can germinate and grow.
Giant Sequoias Yield Longest Fire History From Tree Rings
California’s western Sierra Nevada had more frequent fires between 800 and 1300 than at any time in the past 3,000 years, according to a new study based upon tree-ring research.
The report, Multi-Millennial Fire History of the Giant Forest, Sequoia National Park, California, USA, was published in the electronic journal Fire Ecology in February.
A 3,000-year record from 52 sequoia trees show that California’s western Sierra Nevada was droughty and often fiery from 800 to 1300, according to the study led Thomas Swetnam, Director of the University of Arizona Laboratory of Tree Ring Research.
Scientists can crossdate multiple samples (no live trees were sampled) by matching characteristic patterns of signature rings, usually years in which the trees grew little. For example, 1580 was an exceptionally dry year that is reflected as a very small ring in most giant sequoias. Once dated the actual calendar years in which fire scars were formed can be determined and a history of fire reconstructed.
The scientists found the years from 800 to 1300, known as the Medieval Warm Period, had the most frequent fires in the 3,000 years studied.
“While its intuitive that climate patterns influence fire regimes, this study’s data provides some of the first looks at how past fire regimes responded in a sequoia grove. Periods of droughts saw more frequent, though smaller fires, as a rule. Wetter periods saw less frequent fire. However, this also gave fuels a chance to accumulate and this led to larger fires.”
Mikey Mann has erased the MWP, and Fox News thinks that the current fire is going to kill trees which have survived hundreds of fires over the last 3,000 years.
A massive wildfire racing through the Yosemite wilderness — fueled by high winds — is threatening San Francisco’s fresh water and power supply as well as California’s iconic giant sequoias.
What we can conclude from the tree ring data, is that human stupidity has never been higher at any time during the last 3,000 years. Forests need regular fires. Can these morons please stop whining every time one occurs?
