Egyptology News: Evidence for the Ten Plagues of Egypt at time of Ramesses II

I read a great article giving natural explanations for the 10 plagues leading to Israel's Exodus out of Egypt.

The Telegraph (Richard Gray)

Researchers believe they have found evidence of real natural disasters on which the ten plagues of Egypt, which led to Moses freeing the Israelites from slavery in the Book of Exodus in the Bible, were based.

But rather than explaining them as the wrathful act of a vengeful God, the scientists claim the plagues can be attributed to a chain of natural phenomena triggered by changes in the climate and environmental disasters that happened hundreds of miles away.

They have compiled compelling evidence that offers new explanations for the Biblical plagues, which will be outlined in a new series to be broadcast on the National Geographical Channel on Easter Sunday.

Archaeologists now widely believe the plagues occurred at an ancient city of Pi-Rameses on the Nile Delta, which was the capital of Egypt during the reign of Pharaoh Rameses the Second, who ruled between 1279BC and 1213BC.

The city appears to have been abandoned around 3,000 years ago and scientists claim the plagues could offer an explanation.

Climatologists studying the ancient climate at the time have discovered a dramatic shift in the climate in the area occurred towards the end of Rameses the Second's reign.

I don't have a problem with natural explanations for the plagues, but I don't think the explanation fits the evidence given in Exodus for two reasons; It does not explain why Goshen, where the Israelites,  did not experience the same plagues as the rest of Egypt. And two how do they account for the speed and near simultaneity of these events? The bottom line is Israelites did not free themselves, but God did it for them.
