Anxious citizens everywhere are bracing for the last climate-change propaganda blitz of 2017, timed to coincide with next week's COP23 summit in Bonn—and also with the onset of cold weather in the northern hemisphere, which invariably reduces alarmist media coverage of climate issues. From the World Meteorological Organization comes the news this week that for the first time in 800,000 years, CO2 emissions have reached 403.3 parts per million. This is "unacceptable," scolds Erik Solheim of the UNEP, for it puts us nowhere near our Paris targets and shows that "we are not doing nearly enough to save hundreds of millions of people from a miserable future." Not to be outdone, The Lancet has published a study of the deleterious impact of climate change on human health—making headlines worldwide (but also causing some skeptics to question how such findings square with WTO data showing global human-development indicators rising in virtually all categories). Other climate crises heralding COP23 include alarming new forecasts for sea-level rise, the plight of climate-change refugees, mysterious Bahamian boulders, off-track migratory birds, and a possible insect Armageddon. Look for world leaders to hold fast to the doomsday script in Bonn—even the Canadians, whom the U.N. has singled out as the worst of the Paris laggards.
