Two years ago the big scientific news was that increasing CO2 levels were increasing plant productivity around the world. CO2 is the global food supply so this is good news indeed.
CFACT’s Larry Bell explained the science in this article:
CO2 ‘pollution’ is greening the planet
Global greening is the most important ecological trend on Earth today
CFACT, May 9, 2016
Now NASA has produced a spectacular short video based on this research together with other satellite images:
20 Years of Global Biosphere
NASA Scientific Visualization Studio, Nov 2017
It basically shows the greenness of the Earth every month for 20 years. Along the way we see the seasons, the ebb and flow of snow cover, and a lot more.
The fact that atmospheric CO2 is feeding the world, and feeding it more, needs to be taught. Along with the new NASA video, there are bunches of earlier videos that can be used to get this vital message out. Some examples follow.
1. NASA has this earlier video that makes the point explicitly:
Rising CO2 Levels Greening Earth
Released on April 25, 2016
Goddard Media Studios
2. Here is a semi-technical animation that explains the science:
Increasing carbon dioxide levels affect plant growth
G. Morwong et al, Oct 2015, 10 minutes
3. British journalist Matt Ridley really took up the cause in 2016. Here is his presentation, the invited annual lecture of the prestigious Global Warming Policy Foundation:
Matt Ridley: Global Warming Versus Global Greening
GWPF Annual Lecture, October 2016, 40 minutes
Greenhouse operators have long known that increased CO2 increases plant productivity. So much so that they spend money making it happen. Here are some videos about it:
Everest Fernandez, Just Growers, March 2016, 5 minutes
2. CO2 THE MAX SYSTEM TUTORIAL – SIMPLE CO2 GENERATOR FOR PLANTS
co2themax, May 2012, 5 minutes
There are also these two great classic videos, both worth watching today:
1. The Greening of Planet Earth (1992)
Posted by CO2 Science, 28 minutes
2. The Greening of Planet Earth Continues (1998)
Posted by CO2 Science, 29 minutes
Here are two major websites that have a lot of information on atmospheric CO2 and plant productivity:

It should be noted that there is a bit of a semantic confusion in some of these discussions. The increase in pliant productivity is sometimes incorrectly called a “fertilization” effect. In reality fertilizer is like vitamins. It provides trace elements that plants need a tiny bit of.
In contrast, CO2 is the actual food of plants. When you watch a plant grow you are watching CO2 (and water) building a body. When you watch a child grow, or play, you are watching that CO2 be reprocessed. Everything that we eat is primarily composed of processed CO2.
That the world’s food supply is increasing thanks to increasing CO2 is a science story that needs to be told, loudly and well, in today’s absurdly anti-CO2 policy environment.
