On Thursday, July 7, 2016, I wrote a blog alert quoting Lawrence Soloman’s article in the Financial Post: “Hooray! There’s reason to celebrate that CO2 levels are rising.”
What’s to celebrate? Recent finding from NASA and the University of Otago, New Zealand provide us with the first global picture of the seasonal change in the patterns of vegetation – known as phenology, the timing of leaf emergence and how CO2 is altering the cycle. The planet is getting greener. Plants love CO2. But……….!
Earlier leaf emergence moving out of synch with the life cycles of birds, pollinators and mammals will have a significant impact on the ecosystem and could lead to higher extinction rates of species dependent on leaf cycle.
Are these early warning indicators of catastrophic ecosystem changes? NASA is sending up three missions to investigate the role of plants in the breathing earth’s carbon and water cycle.
Edward O. Wilson's book, Half Earth: Our PlanetsFight for Life, proposes an achievable plan to save our imperiled biosphere: Devote half the surface of the Earth to nature. It’s a good start.
