Drought Damage Will Cause Widespread Forest Death by 2050.

It is well known that climate change is causing all sorts of extreme weather, and may lead to events such as 35-year-or-longer “megadroughts” that will be the worst we’ve seen in 1,000 years. Now researchers are giving us another glimpse into the future, saying that drought damage will likely cause widespread forest death by the 2050s as a result of climate change.

A team lead by the Carnegie Institution describes in the journal Nature Geoscience how tree mortality can radically transform ecosystems, affect biodiversity, harm local economies, and pose fire risks, and even further increase global warming.

“A forest die-off over a large area like the Amazon Basin, could have a major impact on Earth’s system as a whole,” researcher Joseph Berry explained in a statement.

On one hand, rising concentrations of carbon dioxide (CO2) can benefit trees and help them use water more efficiently. On the other hand, rising temperatures and resulting droughts from climate change can cause many forest trees to die off. The latter is what occurred during the 2000-2003 drought in the American southwest, which triggered a widespread die-off of about 17 percent of aspen forests around the region – including most of Colorado, as well as parts of the western United States and Canada.

They used this newfound information to predict drought-induced forest mortality in the future. What they realized was that if greenhouse gas emissions continue to rise, the threshold for widespread drought-induced vascular damage would eventually be crossed.

This, in turn, will lead to widespread tree deaths on average across climate model projections in the 2050s.

“Finding the thresholds in plant physiology after which climate stress causes tree mortality will allow us to resolve uncertainty over the fate of forest ecosystems in a changing climate,” said lead author William Anderegg. “But most importantly, a lot rides on human decisions to slow climate change. The clock is ticking on the future of these forests.”

Unfortunately, with the world’s 2 degrees climate goal being “utterly inadequate,” according to a recent report, the likelihood that we will save the world’s forests in the future seems bleak.

  1. After droughts, always rains / after rains always come droughts, that’s nature. Dams attract more and regular clouds from the sea onto the land.

    Brazil has sufficient amount of rain, I wish Australia gets half as much. Occasional droughts and floods is nature’s / gods way: of culling the weak and making space for the more resilient and more adaptable => nature’s ”natural selection process” – always was and always will be. When too many animals -> with occasional drought, nature is always doing what’s appropriate. In other words: -”nature is against 20 million in Sao Paolo. To correct you again: don’t blame the natural processes, blame the pope for not allowing contraception Please read my post, to see: Australia CAN increase the rainfall and many other countries – if it wasn’t for the phony green’s sick ideology!
