The recent History Channel Show about the Little Ice Age said that it was the cause rather than the effect of the Black Death.

They must be revising history to jive with Al Gore's Gore-Bull Warming.
The Black Death began in 1347-1348 and came in a few waves, each time less deadly.
The "Little Ice-Age" began about 1645.

A lot of trees grew back over those couple of hundred years.

Wikipedia's article on dating of the Little Ice Age:

'For this reason, any of several dates ranging over 400 years may indicate the beginning of the Little Ice Age:

1250 for when Atlantic pack ice began to grow
1300 for when warm summers stopped being dependable in Northern Europe
1315 for the rains and Great Famine of 1315-1317
1550 for theorized beginning of worldwide glacial expansion
1650 for the first climatic minimum
In contrast to its uncertain beginning, there is a consensus that the Little Ice Age ended in the mid-19th century.'
