[MCN] Heat: An outlook for ponderosa pine, circa 2007

[Lance Olsen]

"For widespread species such as lodgepole pine, a 
3C temperature increase would increase growth in 
the northern part of its range, decrease growth 
in the middle, and decimate southern forests 
(Rehfeldt et al., 2001)."

"What can be said with some assurance is that 
there is a unique and nearly ubiquitous compound, 
with the empirical formula 
H(2960)O(1480)C(1480)N(16)P(1.8)S, called living 
matter.  Its synthesis, on an oxidized and 
uncarboxylated earth, is the most intricate feat 
of chemical engineering ever performed - and the 
most delicate operation that people have ever 
tampered with."
