CO2 is Making the Planet Greener

CO2 is making the planet greener.

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%).

Betcha that made the nightly news headlines for weeks right … right?

Sea Ice Extent (Global Antarctic and Arctic) – Day 46 – 2017

Oscillations.

The following graph is just for day 46 back to 1979. The interesting thing is how the oscillation from high to low is increasing in amplitude.
