   In the Arizona mountains the forests are falling apart. One reason has to do with drought that may or may not be the result of permanent climate change…the jury is still out in that regard, however a second problem involves the extended length of the summer season and the shortened length of the winter season…definitely climate change related. Bark beetles thrive in the extended summers and not near as many die off in the shorter winters. Between bark beetle infestations and drought what is now forest will most likely become grass and shrub land over time. The ‘forest’ animals will attempt to move higher into the mountains where the climate has maintained more ‘normal’ conditions, but there’s a limit to how high either the treeline or the animals can go. Basically the ‘trees’ can’t adapt fast enough to these rapidly changing conditions, so over the next decade or so it’s pretty much curtains for this particular ecosystem. Bummer, eh?

   There is a fear the world over as temperate woodland today may become tomorrows desert.

   Early warning systems are "clearly" needed to better monitor the ecosystems expected to undergo abrupt and potentially irreversible changes as the climate warms this century
