I am very much in support of Global Warming. The Earth is colder than it should be to support maximal life. There are poles on the Earth where it is too cold for almost anything to grow, but there is no place that is too hot for massive amounts of plants and animals to thrive (due to mountain-ranges extracting moisture from the air, there are deserts where it is too dry for life to thrive, but that also applies to cold areas). Further, carbon dioxide is plant-food. Plants require it in order to live. And the higher the CO_2 concentration, the faster-growing, larger, more robust, and more disease-resistant plants are. Hence, for farming, the higher the yield per units of input there will be. The real horror and tragedy would be if another Ice Age came upon us, as there would be a massive portion of lifeforms killed-off thereby (humans, also). So too, it is already known from the prehistoric ice-core samples that CO_2 does not drive the Earth's warming and cooling cycles, but rather CO_2 rises in response to the Earth warming, due to the oceans releasing dissolved CO_2 (as with gases, more gas is driven out of solution the higher a liquid's temperature is). And hence also, there cannot be any runaway-heating effect due to increased levels of CO_2, or else it would have already occurred, i.e., there could never be the Ice Age cycles. Indeed, there were many times in the Earth's past when CO_2 was much higher than at present. During those times one had megaflora (and also megafauna eating it) which the higher CO_2 levels allowed, but no runaway-heating.
The truth is that a ten degree increase in the global climate warming is likely to be optimal.
The solution has existed for 70 years it's called nuclear power. The fact that the world doesn't run on nuclear is the greatest crime against humanity ever perpetrated.
