Global warming can't slow growth of redwoods or sequoias, new study shows - San Jose Mercury News
"We're not seeing any evidence of declining growth rates," said Steve Sillett, a forestry professor at Humboldt State and nationally known redwoods expert. "In fact, a lot of the sites are exhibiting increasing rates of growth over the last 100 years."
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...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.
