Global warming may be helping redwoods and sequoias grow, new study shows
Yet another tax funded study has come out proving what I learned in 7th grade science, plants love CO2, in this case it’s the redwood trees of California.
Redwood forests near the California-Oregon border have seen the largest surge in wood production, with growth rates since the 1970s up to 45 percent faster now than at any time in the past 200 years.
The discovery has generated guarded optimism among conservationists.
“Redwoods are an incredibly hopeful story in the midst of seemingly catastrophic environmental change around us,” said Emily Burns, science director for Save the Redwoods League, a San Francisco nonprofit that is sponsoring the research. “They are growing vigorously.”
Water remains a concern, however. A study published three years ago found that the amount of fog in redwood areas along California’s coast has fallen 33 percent over the past century. Scientists were concerned about that, but so far the lack of fog may have allowed more sunlight to reach the trees, said Todd Dawson, a lead scientist on the team and director of the Center for Stable Isotope Biogeochemistry at UC Berkeley.
The problem is these geniuses aren’t sure why the trees are doing better.
It may be that the trees prefer warmer temperatures, or that they are benefiting from more sunlight, a longer growing season or even decades of fire suppression. Or they might even be responding well to higher levels of carbon dioxide in the atmosphere.
Nobody knows yet.
Any farmer or greenhouse owner or anyone who paid attention in 7th grade science knows that CO2 is what makes plants grow, it’s called photosynthesis. In fact greenhouse operators a lot of times will put CO2 Generators in the their greenhouses to promote plant growth.
For only “pennies a day,” any greenhouse owner can produce CO2 to help increase plant yields in their greenhouses. That’s the message on CO2 generators sold by greenhouse supply companies across the United States and Canada. “1,500 ppm [of carbon dioxide] can be achieved… these generators automatically provide the carbon dioxide needed to meet maximum growing potential for only pennies a day,” the ad says.
Maybe these researchers should watch this video comparing 2 plants in 2 different co2 environments.
