You can pretty much guarantee none of that will happen because of “global warming.”

Climate change will disrupt not only the natural world but also society, posing risks to the world’s economy and the food and water supply and contributing to violent conflict, an international panel of scientists says.

The warnings came in a report drafted by the United Nations-backed Intergovernmental Panel on Climate Change. The 29-page summary, leaked and posted on a blog critical of the panel, has been distributed to governments around the world for review. It could change before it is released in March.

“We see a wide range of impacts that have already occurred … on people, ecosystems and economies,” said Chris Field, a scientist at the Carnegie Institution for Science and co-chairman of the group writing the report. “Looking into the future, we see increasing risks that are more pervasive and more severe with greater amounts of climate change.”

Field and an IPCC spokesman confirmed the authenticity of the draft. “This is a close-to-final work in progress,” Field said.
