climate change and wilderness

Excerpt

Of particular importance to wilderness values and their stewardship are changes to water, fire and biodiversity conservation.

  • Water. Climate change in western mountains is projected to decrease snow pack, increase winter flooding, and reduce summer stream flow, making it likely that critically important water supplies will decrease (13). Given this, the water that falls in wilderness headwaters will be increasingly important for surface and underground water recharge to municipal water systems, making protection of wilderness water quantity and quality particularly important.
  • Fire. Although climate change effects on precipitation will be variable and are uncertain, warmer temperatures, reflected in longer growing seasons, drier soils and drier fuels have already been implicated in an increase in the frequency, intensity and size of wildfires (14). If the risk of catastrophic fire increases, it will be more important than ever to move beyond exclusive reliance on traditional fire suppression to fire management policies that better balance the short and long term risks associated with fire.
  • Biodiversity conservation. Between 20% and 30% of plant and animal species are likely to be at an increased risk of extinction if increases in global average temperatures exceed 2.7 to 4.5° F (15). Species distributions will shift and this, along with climate-induced changes to the physical environment, will result in protected area ecosystems that differ substantially from those of the past. Modeling suggests that more than 40% of the protected areas in Canada will experience a change in biome type (16).

“What we’re understanding is that the human body is actually very sensitive to heat, and that suggests pretty much everybody’s at risk,” said Camilo Mora, the paper’s lead author. “It’s not just the elderly. It’s not just the poor. It’s everybody.”

“The attitude is: If it’s killing someone else, I’ll deal with it tomorrow,” he said. “This is coming at our doors right now.”

=============================
“We are living on the surface of this planet … and with its climate and atmosphere. It has always been the task of mankind to find the right answer to the problem 
these conditions set us, and even today we cannot think that we have found a sufficient answer.” 

Alfred Adler (1870-1937)

“One can quibble with some assumptions or tweak Smil’s calculations, but the bottom line will not change, only the time it may take humanity to reach a crisis point.”
