For a long time it was assumed that the amount of nutrition in vegetables was determined by the vegetable's genes not by the way it was grown; they working theory being that if the vegetables didn't have everything they need they wouldn't grow well. Because of this for the longest time organic and chemically grown vegetables were never compared.
Organic vegetables often do have more vitamins but in addition they also have much higher levels of the phytochemical we know prevent disease. Plants use these chemicals to fight pests and infection and when they are not protected by chemical pesticides they produce more of their own chemicals.
As far as climate change goes, the vast majority of climate scientists do believe that mankind's release of carbon into the environment from burning fossil fuels is changing our climate. The skeptics are the fringe view but they are so well funded by the industries who have the most to loose from carbon limits that many people think the jury is still out. Just like tobacco companies bankrolled any doctor or scientist who would say that tobacco isn't dangerous or harmful energy companies are bankrolling climate change skeptics.
There is a difference between climate and weather. Anyone who doesn't understand this lacks the knowledge to have any kind of intelligent conversation about climate change.
