We need more carbon dioxide in the atmosphere. CO2 helps plants to grow. This is proven in greenhouses that use CO2 to grow plants better. We need more and cheaper food. As it is, there isn't enough CO2 in the atmosphere to grow good and abundant food. If CO2 creates more warming of the globe, we need that too. We need to warm up the Northern lands, and Antarctica for easy habitation. Any excess water will be evaporated into the atmosphere to block the sun's radiation so we don't have an abundance of global warming. The greenhouse effect will correct itself so that we will have more room on earth to live. All that extra moisture will green up the Sahara Desert like it used to be 5,000 years ago. We can turn it into a garden. All that science that says global warming is bad, is speculation.
