Another way to think of this is 14% higher crop yields. Probably not actually 14%, but you get the point.
Exactly. Growers pump CO2 into greenhouses to increase productivity. CO2 and 'global warming' would be a good thing if it were actually happening.
Crop yields have increased a lot more than 14%. The article says that due to the extra CO2, crop yields in Germany have increased by 30%.
It's almost like they're made out of carbon or something.
There are a lot if reasons for increased crop yields. Also depends on when you start looking. Minor increases in co2 only accounts for a small portion of it.
