Problems with a global flood.
And:
A flood geologist recants.
An excerpt:
"Sedgwick's rejection of a hypothesis which was contradicted by the empirical evidence, despite his religious beliefs, is the act of the true scientist, and stands in stark contrast to the example provided by modern young-earth creationists. The modern YEC is in posession of the same data that Sedgwick was -- as well as over 150 more years of research -- but is unwilling to make the same concession Sedgwick did, even in the face of more overwhelming evidence.
Instead, the modern YEC takes a unique perspective. Instead of treating the deluge as a hypothesis in need of test against the evidence, and subject to being discarded if found to be contradicted by the evidence (as Sedgwick did), modern YECs declare the deluge, its scope, and effects to be definite, indisputable FACT, not subject to any discussion. Instead of modifying their view of events based on the empirical evidence, they insist that the basic facts of their history are absolutely true, and that the evidence must be interpreted in this light. This, in turn, leads to a vicious cycle in their science-so-called, as they tack ad hoc modifications onto ad hoc modifications."
