Two new papers make extraordinary claims about comets and life - and NASA goes into damage control

Napier et al. assert that life originated in comets, not on planets like Earth. Kennett et al. believe that a large comet impacted North America just 13,000 years ago, causing a mass extinction. For a critique, read on.

Comment: Seems the people at NASA still don't like cometary showers invading the inner solar system. Their "evidence" is the lack of evidence that would explain what their theories predict about comets, dismissing the compelling evidence "on the ground", albeit a lack of a crater, but that could be explained if the comet impacted the Laurentide ice sheet itself, despite their dismissals. It's as if the Inquisition demanded Galileo disprove the bible's contention that there are four corners of Earth before proposing the theory that the earth is, in fact, round. And what about this crater discussed here? And what about the Carolina Bays?
It is generally accepted today that the Tunguska event can only be attributed to a rare encounter with a "comet," or incoming body of such a nature that it left no stony or ferrous material, but simply vaporized and scorched the earth below in a rare display of high energy physics.

To explain the Bays, Kobres proposes a similar encounter, albeit of larger proportions and more accurately described as a "near miss." The "Kobres Event" proposes that a "comet," if you like, whipped past the Earth, exchanging enormous energy but not impacting directly to form a typical crater. It is demonstrable that such an encounter would show an intense flash of heat onto the ground below. This heat would have caused moister portions in the Pleistocene landscape to explode into steam, leaving the depressions in the ground that we know today as "Carolina Bays."

Record rainfall drenches Detroit

A day of record rainfall Monday in Metro Detroit caused havoc for motorists and residents who endured power outages and severe flooding and turned some streets into muddy swamps that left 100 homes in Dearborn inundated.

Through 7 p.m. Monday 1.62 inches was reported at Detroit Metro Airport, passing the one-day record of 1.5 inches set in 1904, said National Weather Service meteorologist Greg Mann.

Scientists ask: Where have all the dolphins gone?

Sightings by marine scientists of dolphins in the north Atlantic's Bay of Biscay have dropped off by 80 percent compared to the same period in 2006, a wildlife conservation group said Wednesday.

The alarming drop in numbers of the Bay's three most common species of dolphin -- the striped, bottlenose and common -- can be attributed to one or both of two causes, Clive Martin, senior wildlife officer for the Biscay Dolphin Research Programme, told AFP.

The city along with the rest of the tri-state region is feeling the chilly effect of a cold front sweeping through the region, accompanied by cool rain showers.

Tuesday's high temperature in Central Park was just 59 degrees. The normal high for Tuesday was 82 degrees. The normal low was 67.

California fire grows to be state's second largest

A California blaze burning since early July grew to be the second-largest state wildfire in modern history on Tuesday, officials said as firefighters partly blocked it by a firebreak.

Even as crews made gains in the Santa Barbara County backcountry, others battled a new blaze in canyon lands east of Los Angeles and another in mountains outside Palm Springs.
