Global Warming?
Trees to the Rescue!
By Brian Thomas, M.S. *
Americans are all too familiar with
environmental activists' gloomy projections of global crises, including the
assertion that mankind's gaseous carbon dioxide emissions will inevitably send
the planet into an irreversible greenhouse sweat box.
In contrast, ICR articles have noted how
belief in evolution largely underpins the common view of a fragile planet.
Some of those same articles introduced the
idea that God-designed systems maintain healthy levels of atmospheric gases
required for life.
So how should the news that the world's
forests are greening because of increased carbon dioxide be interpreted?
Forest scientists have been watching a
pleasant trend, even amidst unpleasant environmentalist diatribes—the world's
forests are expanding, even in arid regions.
A recent collaboration of scientists analyzed
carbon dioxide data taken from decades-old monitoring stations.
They
found that forests "have become
dramatically more efficient in how they use water," according to
Harvard news.
And the key to that efficiency was an uptick
in atmospheric carbon dioxide. Plants simply find it easier to extract carbon
dioxide from air that has more of it—which they then use for more efficient
photosynthesis.
Though
he was quick to say that the biosphere's future might still collapse, Trevor
Keenan, lead author of the paper published in Nature, told Harvard news,
"This could be considered a beneficial effect of increased atmospheric
carbon dioxide."
Keenan
also said, "What's surprising is we
didn't expect the effect to be this big. A large proportion of the ecosystems
in the world are limited by water—they don't have enough water during the year
to reach their maximum potential growth. If they become more efficient at using
water, they should be able to take more carbon out of the atmosphere due to
higher growth rates."
So, in effect, the world's forests are helping
sequester excess carbon dioxide, all without any human intervention.
And it appears that the warming trend itself
proceeded primarily without human intervention, too.
A decrease in the rate of warming within the
last fifteen years has surprised many climate scientists.
Although still in the minority, a growing
number of them link weather trends to solar activity.
The failure of climate models to anticipate
this decrease in the rate of warming may have resulted from a failure to link
solar activity with warming.
Trees have been indispensable throughout
history for the ways they have directly benefited human and animal life.
This news of a greening planet brings yet
another reason to thank God for trees.
Forests help balance levels of atmospheric
gases integral to living things.
