  • Second world war dead washed up by Pacific Ocean's rise - caused by global warming

    South China Morning Post ^ | June 8, 2014 6:27 GMT | Agence France-Presse
    Skeletons of second world war soldiers are being washed from their graves by the rising Pacific Ocean as global warming leads to inundation of islands that saw some of the fiercest fighting of the conflict. On the day Europe commemorated the 70th anniversary of the storming of Normandy beaches in the D-Day landings, a minister from the Marshall Islands, a remote archipelago between Hawaii and the Philippines, told how the remains of 26, probably Japanese soldiers, had been recovered so far on the isle of Santo. "There are coffins and dead people being washed away from graves; it's that serious,"...

    Cavitation by John D. Morris, Ph.D. "One glance at Grand Canyon evokes wonder at the extensive erosion that occurred—but the canyon is only the final whisper of a grand-scale event. The massive erosion episode leveled off and gouged out the Colorado Plateau, covering much of Arizona, Utah, New Mexico, and Colorado. The present-day Colorado River hardly seems capable. Something of a much larger scale accomplished this!...." more...
  • The American Left and the Erosion of Public Discourse

    American Thinker ^ | 3/8/12 | Steve McCann
    Much has been made of the precipitous decline in the level of discourse in the United States. Many attribute this to the coarsening of the language and the ever-widening gulf between the various factions in the political spectrum. However, these factors are a symptom of a current underlying and foundational dilemma: the inability of not only the general public, but nearly all of the so-called societal leaders and opinion-makers to generate an original thought, as well as a stubborn refusal to use reason and logic when confronted with irrefutable facts and arguments. These traits can be explained, insofar as the...

So here are several images from another of those amazing state parks in America, this one called the Valley of Fire State Park in Nevada, which is within driving distance of Las Vegas (and you can apparently drive through part of it). The reason for this particular posting is that one of the many arches in the park fell down very recently. Erosion happens.

    For today's Halloween GPoW, I challenged myself. I have frequently posted pictures of volcanoes, waterfalls, caves, arches and bridges, canyons, and mountains; I've occasionally veered off that path with landslides, remote-sensing views, and a couple of crystals and minerals. So my challenge was to come up with something DIFFERENT; unusual, photo-worthy, and significant geologically. And also something a bit relevant to Halloween. See if you think I succeeded. All of these are in the United States.

    Far too few among the Christian community are willing to remain steadfast in their beliefs, in the face of the enormous pressures of liberal social change. Fortunately, Bruce N. Shortt exemplifies the meaning of such worthy resolve. Last year Shortt, along with T.C. Pinckney, made waves at the 2004 Southern Baptist Convention (SBC) by stating the obvious. America’s educational system has, over the past several decades, completely degenerated from any pretense of promoting academics. Instead, it is primarily focused on a program of indoctrinating students towards countercultural social transformation. Relentlessly working to eradicate any references to God or traditional morality,...

    NEW ORLEANS - New measurements of Hurricane Ivan's erosion of beaches, dunes and barrier islands along the Gulf of Mexico underscore how vulnerable the American shoreline is to such storms, a U.S. Geological Survey (news - web sites) oceanographer says.

    Despite extending the unprecedented 30-hour talkathon on the Senate floor by more than nine hours, Republicans failed to force a vote on President Bush's three judicial nominees deemed too conservative for the American mainstream by Democrats. Republicans launched the round-the-clock debate Wednesday night to counter Democratic filibusters on the nominations of Texas judge Priscilla Owen and California judges Carolyn Kuhl and Janice Rogers Brown. At the outset, Democrats warned the Republican tactic wouldn't work.
