iONiUM writes: From the article, "The impacts of global warming are likely to be "severe, pervasive and irreversible", a major report by the UN has warned." A major document was released by the IPCC outlining the current affects on climate change, and they are not good. For specific effects on humans: "Food security is highlighted as an area of significant concern. Crop yields for maize, rice and wheat are all hit in the period up to 2050, with around a tenth of projections showing losses over 25%."
Humanity has the stars in its future, and that future is too important to be
lost under the burden of juvenile folly and ignorant superstition.
