More CO2 Please! Climate change is proven good for the environment

California’s giant redwood trees are growing faster than ever before.

2,000+ years old and counting, the giant redwood trees (Sequoiadendron giganteum) in California are having a great time—they are growing faster than ever before. A new study by UC Berkeley and Humboldt State University researchers finds them in a growth spurt that began about 100 years ago and began to accelerate in recent decades.


California’s redwood trees are among the oldest living organisms on earth. Some are over 3,000 years old and still going strong. So what’s the cause of their recent growth spurt?

Tree Food

Apart from a beneficial climate, trees grow when they have an adequate supply of three vital nutrients: (i) water, (ii) soil minerals and—you may be surprised to learn—(iii) carbon dioxide (CO2) in the atmosphere. Without plenty of each of these any tree will wilt or die. Continue reading
