Contra Pope Francis, CO2 and Warming Make Earth Greener

According to the doctrine of papal infallibility, the Pope is never wrong on matters of faith and morals. That is where Pope Francis would be wise to focus his attention, rather than wandering off into politically driven climate pseudoscience, where he is anything but infallible:

Francis urged governments on Friday to make good on their commitments to curb global warming, warning that climate change, continued unsustainable development and rampant consumption threatens to turn the Earth into a vast pile of “rubble, deserts and refuse.”

Meanwhile, from the peer-reviewed journal Nature Climate Change:

Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982–2009. We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (LCC) (4%). CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau.

Warm weather and plenty of CO2 make for a greener planet with more food for everyone — as a schoolchild could have told you prior to the global warming hoax.
