More CO2 helps to feed more people worldwide.
The world’s remarkable ability to increase food production year after year is attributable to mechanization, agricultural innovation, CO2 fertilization and warmer weather. World grain production and amount harvested per acre show that crop and food production has steadily increased, with only positive effects from our changing climate. If more CO2 and warmer weather were going to cause a decline in world-wide food production, should there not have been some recognizable negative effects by now? Contrary to predictions, all the signs point to robust food production, which will increase far into the foreseeable future. We can be grateful for a combination of rising temperatures and increasing carbon dioxide.
