Carbon Dioxide - Earth's saviour. Mother Nature relies on Habit!

Juxtaposition between Observations and
the inaccurate CMIP-5 models/
Juxtaposition: That's the name of the Game; and each generation will play the same.

That's a misquote from Bobby Darin's song "Multiplication," which goes on to say:

Hear me talkin’ to ya: Mother Nature is a clever girl, She reli-es on habit! 

And what is one of Mother Nature's Habits?
Why, hear me talkin' to ya: CO2 is good for you
And good for global greening too." 

A few recently recent releases confirm this:

  1. Study: Too Little Carbon Dioxide Will Destroy Earth;
  2. Carbon Dioxide Is Causing 'Global Greening.' 

 1: Too Little Carbon Dioxide Will Destroy Earth (link)

Do you want to save the planet? Fire up the SUV this holiday weekend and go for a pleasure ride; burn some more coal in your barbecue grill; crank up the house’s AC; and, generally, aspire to a Paul Bunyan-size carbon footprint. Because according to astrobiologist Jack O’Malley-James speaking at the National Astronomy meeting at the University of St. Andrews in Scotland, life on Earth will suffer a carbon-dioxide-related extinction. But contrary to popular-culture belief, the problem will be too little of the naturally occurring gas 
The author of the opinion piece in NewsAmerica   goes on to say that "CO2 needs to hire a PR team, misunderstood and maligned as it is by global-warming proponents."
CO2 actually increases plant yields, accelerates "re-greening" and improves reforestation of the planet.  
The more you really examine the scientific truth about carbon dioxide rather than the politically-charged "hate speech" against Mother Nature being spewed by people like Al Gore, the more you realize CO2 is a crucial nutrient for the Earth's environment and ecosystem. In fact, the vast majority of all the CO2 released into the atmosphere is produced by Mother Nature via animals in the ocean.
Whatever the effect of CO2 on climate, many experts also point out that the computer forecasting models predicting a steadily warming planet are belied by actual temperature records. (See UAH graph above.) [bold added]

2: Carbon Dioxide Is Causing 'Global Greening.' (link - Forbes)

Have Australians heard about this?  

A team of scientists led by environmental physicist Randall Donohue, a research scientist at the Commonwealth Scientific and Industrial Research Organization in Australia, analysed satellite data from 1982 through 2010.
The scientists documented a carbon dioxide “fertilization effect” that has caused a gradual greening of the Earth, and particularly the Earth’s arid regions, since 1982. The satellite data showed rising carbon dioxide levels caused a remarkable 11 percent increase in foliage in arid regions since 1982, versus what would be the case if atmospheric carbon dioxide levels had remained at 1982 levels. 
Carbon dioxide acts as aerial fertilizer and also helps plants thrive under arid conditions. Although global precipitation has increased during the past century as the Earth has warmed, elevated carbon dioxide levels are assisting plant life in warm, dry regions independent of – and in addition to – increases in global precipitation. 
“The effect of higher carbon dioxide levels on plant function is an important process that needs greater consideration,” said Donohue. “Even if nothing else in the climate changes as global CO2 levels rise, we will still see significant environmental changes because of the CO2 fertilization effect.”  (bold added.)

AGU Release No. 13-24 
WASHINGTON, DC—Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide “fertilization effect” has, indeed, caused a gradual greening from 1982 to 2010. 
Focusing on the southwestern corner of North America, Australia’s outback, the Middle East, and some parts of Africa, Randall Donohue of the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Canberra, Australia and his colleagues developed and applied a mathematical model to predict the extent of the carbon-dioxide (CO2) fertilization effect. They then tested this prediction by studying satellite imagery and teasing out the influence of carbon dioxide on greening from other factors such as precipitation, air temperature, the amount of light, and land-use changes. 
The team’s model predicted that foliage would increase by some 5 to 10 percent given the 14 percent increase in atmospheric CO2 concentration during the study period. The satellite data agreed, showing an 11 percent increase in foliage after adjusting the data for precipitation, yielding “strong support for our hypothesis,” the team reports.
