We give you: The Beer of the Future (that we hope doesn’t exist). Without aggressive climate action now, the impacts will be felt even in the beer aisle. Let's work together to make sure none of us have to drink beer like this. https://bit.ly/2XU7KbR

"The paper’s authors reviewed more than 250 published articles that have used satellite data, modeling, and field observations, to understand the causes and consequences of global greening. Among the key results, the authors noted that on a global scale greening can be attributed to the increase of carbon dioxide in the atmosphere. Rising levels of carbon dioxide increase the rate of photosynthesis and growth in plants."
metmike: Why isn't this paper, based on 250........let me repeat that number 250 published articles using the best technology known to science............getting much news coverage?
Because they don't want you to know this.
From the projections: According to climate models, the future looks even greener. The second map shows what the green-up might look like in the future based on the Coupled Model Intercomparison Project (CMIP5) climate model, under a scenario in which increases in greenhouse gases lead to almost 5° Celsius (9° Fahrenheit) of warming by the end of the 21st century. Specifically, it shows the predicted change in the growing season’s “leaf area index” from 2081-2100 relative to 1981-2000. The chart below the map shows the predicted changes by latitude. Notice that high latitudes in the Northern Hemisphere are still expected to change the most.
metmike: There is almost no chance we will see that amount of warming.

Fossil fuels are the only true, green energy!
The authentic science(photosynthesis) shows it with EVERY SINGLE objective measure.
Even deserts are greening up a bit from it.

Satellite data shows the per cent amount that foliage cover has changed around the world from 1982 to 2010.
Increased levels of carbon dioxide (CO2) have helped boost green foliage across the world's arid regions over the past 30 years through a process called CO2 fertilisation, according to CSIRO research.
In findings based on satellite observations, CSIRO, in collaboration with the Australian National University (ANU), found that this CO2 fertilisation correlated with an 11 per cent increase in foliage cover from 1982-2010 across parts of the arid areas studied in Australia, North America, the Middle East and Africa, according to CSIRO research scientist, Dr Randall Donohue.
Crop yields with climate change/increasing CO2........soybeans:
Yields have doubled in the last 40 years:

There obviously are other contributing factors with genetics and farming technology but the +CO2 and weather have been a big plus.
With Corn, it's a different picture because of the introduction of nitrogen fertilizer causing corn yields to triple real fast and nothing to do with CO2 or weather during that initial tripling. However, recent decades have featured a steady increase, along with a steady increase in CO2 and beneficial weather.

A brief history of U.S. #corn yield growth since the 1860s Notable growth in yields was seen after the adoption of modern fertilizers in the 1940s, which made drought years esp. in the 1980s stand out more than before (compare with 1930s Dust Bowl for example).
Here is irrefutable evidence using empirical data to show that the increase in CO2 is causing a huge increase in crop yields/world food production.
We can separate the CO2 effect out from other factors effecting crops and plants with many thousands of studies that hold everything else constant, except CO2.
Observing and documenting the results of experiments with elevated CO2 levels, tell us what increasing CO2 does to many hundreds of plants.
Here's how to access the empirical evidence/data from the site that has more of it than any other. Please go to this link:
http://www.co2science.org/data/data.php
Go to plant growth data base:
http://www.co2science.org/data/plant_growth/plantgrowth.php
Go to plant dry weight(biomass):
http://www.co2science.org/data/plant_growth/dry/dry_subject.php
Pick the name of a plant, any plant and go to it based on its starting letter. Let's pick soybeans. Go to the letter S,http://www.co2science.org/data/plant_growth/dry/dry_subject_s.php
Then scroll down and hit soybeans. This is what you get:

Statistics
| 300 ppm | 600 ppm | 900 ppm | |
| Number of Results | 238 | 25 | 3 |
| Arithmetic Mean | 48.3% | 71.2% | 61% |
| Standard Error | 2.4% | 7.9 | 11.3% |
This tells us that there were 238 studies with the CO2 elevated by 300 ppm. The mean increase in plant biomass was 48.3% from all those studies.
The individual studies are listed below that.
USA Soybean yields in the real world since 1988 have almost doubled while CO2 increased by 85 ppm, so we have strong corroborating evidence.
I added to the title(Death by Greening) to make it more appropriate for the real world observations and honest/authentic projections in light of the fake climate crisis cries(deafening warnings) this week of "we're killing the planet" and "last chance to save the planet"

mm,
I just took some time to look at and understand these studies and NO DOUBT!

Thanks John.
There really is no doubt.
We live in a world with many millions of times more information available to us at our fingertips compared to a century ago.
At the same time, humans have not evolved to where we can turn off our innate, cognitive bias.......which compels us to interpret all information based on what we think that we know.
If we are taught that there is a climate crisis........all new information is interpreted based on that assumption.
This applies in so many other realms too. People go to their favorite politically biased sites to hear the news the way that they like to hear it and they are TAUGHT what to think. Then, when they leave those sites, their brains interpret the million times greater amount of information from all other sources with cognitively biased assumptions that tell them what to allow in and what to reject. It can be 95% against what they think that they know and they will use the OTHER 5% to reinforce what they think that they know and reject every thing else.
Seriously, it's what accurately defines human behavior today in this advanced society.
The optimal level of atmospheric CO2 for many crops is around 900 ppm.
This is more than double the current level:
Optimal CO2 for life more than double current level: See the proof with thousands of studies. Showing Scientific American.....and mainstream science sold to us........ to be wrong about plants and the affects from Climate Change. December 2020
