Climate change has affected forests globally

Monga Bay - Already facing an onslaught of threats from logging and conversion for agriculture, forests worldwide are increasingly impacted by the effects of climate change, including drought, heightened fire risk, and disease, putting the ecological services they afford in jeopardy, warns a new paper published in the journal Nature Climate Change.

The study reviews dozens of scientific papers dealing with the ecological impacts of climate change. They find widespread cases of forest die-off from drought and elevated temperatures, which can increase the incidence of fire and pest infestations like pine beetles. These effects have the potential to trigger transitions to other ecosystems, including scrubland and savanna. But the impacts vary from forest to forest and the authors say more research is needed to fully understand the effects of climate change on forest ecosystems.

I grew up in Minnesota, and later worked in Texas for a few years.

The contrast between the trees in those places was mind-numbing. In Minnesota, with lots of water and real winters that froze the pests, trees were strong, healthy, and long-lived.

In Texas, there's not a lot of water, the pests can operate year-around, and the trees are weak and short-lived.

I can only imagine how terrible it will be if we don't get our act together Real Soon.

Sheez...grow cannabis. Imagine the use of this wonderful plant - material for clothing, rope, paper, medicinal purposes. Need to go on to name ALL the GOOD uses and how much it would save us in more ways than one.
