No, more CO₂ won't help us grow more food
The world looks very different when you understand statistics. Go to https://brilliant.org/simonclark/ to get started for free!
Contrary to what you might think, more carbon dioxide in the atmosphere is actually bad news for growing food. In this video I talk about why more CO2 means a warmer planet, a drier planet, and less food. But more than that, food that actually contains fewer nutrients...

NASA | A Year in the Life of Earth's CO2
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.
Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.
The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.
The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on at...

The Truth about CO2 | 5 Minute Video
Global Warming activists will tell you that CO2 is bad and dangerous. The EPA has even classified it as a pollutant. But is it? Patrick Moore provides some surprising facts about the benefits of CO2 that you won't hear in the current debate.

World’s largest carbon dioxide sucking factory opens in Iceland - BBC News
The world’s largest factory to capture carbon dioxide from the air has begun operations in Iceland. Reducing the amount of CO₂ in the Earth’s atmosphere would help reduce the effects of climate change.
It showcases a developing technology considered by some to be an important tool in the fight against climate change but sceptics question how much impact it can really have.
Is it a futuristic vision of how to save the planet from runaway climate change, or a futile expense that distracts from the urgency of slashing co2 emissions?
According to the companies that constructed the plant, Climeworks and Carbfix, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide ...

Edited by Luke Negus
Video essay about the effects of climate change on agriculture, how climate change will hurt food production, including how climate change will make food less nutritious. More CO2 means more photosynthesis, but more CO2 also means a warmer planet, which means less food, and food lacking in protein. In this video - similar to videos from SciShow, Crash Course, ClimateTown, Our Changing Climate, Veritasium, and Smarter Every Day - I talk about how global warming will impact how much food we can grow.

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.
Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.
The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.
The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.
While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.

Script:
What are two of the dirtiest words in the English language? Well, if you're concerned with Global Warming as so many people are these days, the answer is obvious. The two words are "Carbon Dioxide." Or as it is known by its chemical symbol -- CO2. One atom of carbon and two atoms of oxygen. If we pump much more of it into the atmosphere, the argument goes, we're going to alter the climate. Catastrophically.
According to the Intergovernmental Panel on Climate Change, the IPCC, CO2 emissions from fossil fuels, which constitute 85% of our energy use must be reduced to zero by 2100. If we don't save ourselves from ourselves, we're toast. That's the claim.
Here's what strange, though. All life is carbon-based, and the carbon for all that life originates from carbon dioxide in the atmosphere. All of the carbon in the fossil fuels we are burning for energy today was once in the atmosphere as carbon dioxide before it was consumed by plankton in the sea and plants on the land. Coal, oil, and natural gas are the remains of those plankton and plants that have been transformed by heat and pressure deep in the earth's crust.
In other words, fossil fuels are 100 percent organic and were produced with solar energy. Sounds positively green.
If there were no carbon dioxide in the Earth's atmosphere, the Earth would be a dead planet. Period. Talk about catastrophic climate change. Take away CO2 and you'd have it. And yet, the US Environmental Protection Agency has deemed this essential ingredient for life a pollutant! But, how can something that makes life possible be bad?
Before I deal with that question, let's get clear on our terms. It has become common to refer to the emissions from burning fossil fuels for energy as "carbon" emissions. That is entirely misleading. Carbon dioxide is not carbon. Carbon dioxide is a colorless, odorless, tasteless gas which is an indispensable food source for all living things. Can you have too much of it? In theory, yes. That's what climate alarmists say is happening now -- CO2 levels are getting too high. Are they right? Well, if we look at the big picture we find something surprising.

According to the companies that constructed the plant, Climeworks and Carbfix, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide out of the air every year.
