Our Latest Global Warming Scare

The IPCC report insists that meeting this target requires "rapid and far-reaching" changes—all unspecified—in a wide range of areas including land, energy, industry, buildings, transportation, and cities. These changes, the report insists, must reduce carbon dioxide emissions to about 45 percent of 2010 levels by 2030 and to a neutral level of no new carbon dioxide emissions by 2050.

Much press coverage has embraced the report's conclusions. The New Yorker stresses the dire warnings of the IPCC report. The Guardian speaks of the "urgent changes" needed to contain climate change underneath its headline picture of a raging California wildfire. Yet it is here that the story starts to unravel from both a scientific and economic perspective. The unstated narrative behind the picture is that temperature increases due to global warming will cause environmental catastrophes. But in the case of forest fires, this claim is simply untrue: in the United States, the number of forest fires has been down by about 86 percent since 1930, and the current year ranks as the 40th highest on record. To be sure, the risks of fire today remain great but for reasons that are unrelated climate change. Higher levels of CO2 make plants more drought resistant, which increases the amount of burnable material. What matters most, however, is not temperature change, but finding the proper techniques for forest management. Yet one weakness of the IPCC report is that in its discussion of forest fires, it does not mention alternate causes.a
