On March 31 the Intergovernmental Panel on Climate Change (IPCC) released the tentative draft of its Fifth Assessment Report (AR5) for Working Group II, which studies the impacts of climate change under various possible scenarios, including actions by governments. (In contrast, the report from Working Group I—which was released in the fall of 2013—studied the physical science underlying projections of climate change.) Although the top brass at the IPCC and their accomplices in the media will do their best to hide it, the fact is that the new report shows just how optimistic we should be about the future.
