Speaking of New Orleans, here is the NOAA prediction for the most likely path for Hurricane Gustav (actually, it is Tropical Storm Gustav right now, but it should strengthen and become a hurricane again soon).
It is unlikely that Gustav will be a category 4 or 5 hurricane like Katrina, but it could still do a lot of damage wherever it hits. This map is called a 5-day cone, with the stippled area from south Texas to the Florida panhandle indicating the possible landfall area, and the black dashed line being the most probable path.

Heavy monsoon flooding in India has claimed close to 1000 lives, and millions more have been displaced. The most dramatic event has been the abrupt change of course of the Kosi River in northern India. The Kosi River flows from the Himalaya Mountains into the Indian state of Bihar. The flood-swollen river has broken through its banks and re-occupied a channel it had abandoned over 200 years ago, resulting in a 60 km shift in its course.
NASA’s Earth Observatory site has two images. The top image shows the new course of the river on August 24th following the channel shift; the bottom image shows the river a few weeks before.
ReliefWeb has a good article on this disaster: Kosi devastates Bihar; 2 million homeless. The first two paragraphs read:
This is India’s Katrina, only the challenges could be bigger. Like the Mississippi breached the levee to drown an unsuspecting New Orleans in the US, the mighty Kosi river in north Bihar has broken its embankment to pick up a channel it had abandoned over 200 years ago, drowning towns, numerous villages and rendering over a million homeless. Many are reported to have died.
Officials here say it’s a catastrophe unlike annual floods. The brimming river has breached its embankment near the Bhimnagar barrage, close to the Nepal border, and is rushing down as a miles-wide stream to the Ganga, over almost 100km south. Unlike floods, this is not calm water but an angry torrent, making relief work very difficult.
In some ways, the situation on the Kosi Plain is similar to the Mississippi River delta in Louisiana. As sediments pile up around the mouth of the Mississippi, it naturally changes its course every few hundred years. The Mississippi is overdue for a channel change, which makes New Orleans increasingly vulnerable to flooding. Likewise, the Kosi River naturally changes its channel, but on a more frequent basis. The map below shows how the Kosi has changed its course numerous times since 1730.
As the Kosi exits the Himalayas, it creates a broad alluvial fan, well over 100 km across. Since the 1730s, the river has migrated from the east (#1 on the map) to the west (#2), and now seems to have taken an abrupt move back to the east.
As Indian officials respond to this crisis, they will need to take geological reality into account, just like planners in Louisiana need to take into account the fact that the Mississippi River would rather take a shorter path to the sea. We humans like things to stay constant. We like sea level to stay the same. We like climate to stay the same. We like rivers to behave and not change course. But the fact of the matter is that all of these things change. At times we can be the masters over nature, but at other times nature will be the master over us. We need the wisdom to know when to conform nature (such as the course of rivers) to our wishes, and when to adapt to the forces of nature that are still greater than us.

Once again, news reports are showing that using human embryonic stem cells for research is not only immoral, but perhaps scientifically unnecessary. An article in the science journal Nature reports that ordinary pancreas cells in adult mice have been transformed into cells that produce insulin. Here are the first few paragraphs from an article on Yahoo news:
Talk about an extreme makeover: Scientists have transformed one type of cell into another in living mice, a big step toward the goal of growing replacement tissues to treat a variety of diseases.
The cell identity switch turned ordinary pancreas cells into the rarer type that churns out insulin, essential for preventing diabetes. But its implications go beyond diabetes to a host of possibilities, scientists said.
It’s the second advance in about a year that suggests that someday doctors might be able to use a patient’s own cells to treat disease or injury without turning to stem cells taken from embryos.
The advantages of using a patient’s own cells, rather than cells from an embryo, are numerous. Not only do we avoid the ethical problems of destroying a human embryo, the genetic match is perfect. We can be thankful for this type of research.

Back in the 1980s, a key book providing both Biblical and geological evidence for an old age for the Earth was Christianity and the Age of the Earth by Davis Young, professor of Geology at Calvin College. It is still a useful book, but it is about to be superseded by The Bible, Rocks, and Time: Geological Evidence for the Age of the Earth, authored by Davis Young, who is now an emeritus professor, and Ralph Stearley, who is also a professor of Geology at Calvin.
The original book, Christianity and the Age of the Earth, played an important role in my education as a Christian geologist. I switched my major to geology my junior year of college because I was fascinated with the Earth and its history. At the same time, I attended a church where young-Earth creationism was the norm; anything else was considered to be a cave-in to godless evolutionism. Through Young’s book (and also through Evolution: Nature and Scripture in Conflict? by Pattle Pun) I came to see that one could make a strong argument from the Scriptures for allowing an old age for the Earth. This saved me, perhaps, from a crisis of faith that others have gone through when they see that the arguments of young-Earth creationism don’t work.
This new book has four sections:
The Bible, Rocks, and Time will be available from Amazon for $19.80 the beginning of October. It is also listed at Barnes and Noble and Christianbook.com. I’ve pre-ordered my copy, and look forward to every page.
[Update 9/10/08: The book is available now from Amazon]

Albert Mohler writes about “Nature-Deficit Disorder” on his blog: Aliens in Creation — A Generation of Nature Know-Nothings. Here are a few quotes:
BBC Wildlife Magazine reports this month that only half of a sample of nine to eleven year old children in Britain could identify a daddy long-legs. A mere 62% rightly identified a frog. Less than half could recognize a tree as an oak.
The findings prompted Sir David Attenborough, the famous British naturalist, to lament the alienation of children from nature. “The wild world is becoming so remote to children that they miss out,” he explained. It turns out that many children gain whatever minimal knowledge of nature they acquire through watching television — not by first-hand observation.
Attenborough went on to argue that this alienation of children from nature could lead to ecological disaster, since these children would grow to adulthood without developing a sense to wonder and appreciation for the natural world.
The BBC Wildlife Magazine study also revealed that playing outside was the least valued pastime for the nine to eleven year olds. Twice as many children preferred time with the computer.
Author Richard Louv has described this phenomenon as “nature-deficit disorder.” In his book, Last Child in the Woods, Louv told of a young boy in San Diego who explained that he preferred to play inside, rather than outdoors, because the electrical outlets are found indoors. Life temporarily apart from electrical devices was, to this boy, an unattractive (or unknown) thought.
God reveals His glory in creation. How can we read the Psalms with insight if we never look and see that the heavens really are telling the glory of God? Something precious is lost when children — or adults — are alienated from the created world. This choice for alienation is a choice to cut ourselves off from what God has given us to enjoy and to appreciate.
Lots of good stuff here. I praise God for Christian leaders like Mohler who point us back to the value of nature as God has made it.
