Remember Ronald Reagan and the “killer trees”?
I’m going to resurrect that story shortly, but to get something up immediately, I have links to and excerpts from two stories.
First, UK Guardian
Global warming: blame the forests
· Research identifies plants as source of methane
· Climate scientists shocked by new findings
Thursday January 12, 2006
They have long been thought of as the antidote to harmful greenhouse gases, sufferers of, rather than contributors to, the effects of global warming. But in a startling discovery, scientists have realised that plants are part of the problem.
According to a study published today, living plants may emit almost a third of the methane entering the Earth’s atmosphere.
The result has come as a shock to climate scientists. “This is a genuinely remarkable result,” said Richard Betts of the climate change monitoring organisation the Hadley Centre. “It adds an important new piece of understanding of how plants interact with the climate.”
Since the first source was the shaky UK Guardian, there needs to be a second (AFP via ABC):
Scientists question trees’ role in global warming
Under the United Nations’ Kyoto Protocol on global warming, the forest is a saint, as trees suck in carbon dioxide (CO2) as part of the natural process of respiration.
By such thinking, if Kyoto signatories plant lots of forests, they create wonderful sponges that absorb the dangerous climate-altering gas.
But what if trees, in addition to taking in CO2, also emit a greenhouse gas of their own?
That scenario is sketched in a new study by European scientists, which if confirmed, would be one of the biggest upheavals in climate science for years.
It would also inflict a serious blow to Kyoto, one of whose key pillars is the faith in “sinks”, as forests are called in the treaty’s jargon.
Until now, the mainstream belief is that atmospheric methane chiefly comes from bugs: from bacteria working in wet, oxygen-less conditions, such as swamps and rice paddies.
But in a study published in the journal Nature, a team led by Frank Keppler of the Max Planck Institute in Germany has found living plants, dried leaves and grass emit methane in the presence of air.
Nor is this gas just a piffling amount.
Bring on the bulldozers (just kidding, people).

UPDATE: Shoot. All I can find are extreme leftist sites that distort the story, which is this — During a 1980 campaign speech or interview, Reagan made the (now more clear than ever) valid point that trees and plants emit gases that can be seen as harmful to the environment. On a flight after that, during the landing approach, aides started joking that the pilot should watch out for the “killer trees.”
UPDATE 2: S.O.B. Alliance member Weapons of Mass Discussion comments: “So, now we know the truth: salad causes global warming. I knew it along…”
UPDATE 3: Tim Worstall: “Quick! Quick! Cut down the rainforests to save the planet! Get rid of the Amazon and plant soya!”
