Ross McKitrick: In other words, the Parliamentary Budget Officer projects that the impact of climate change over the next 80 years will be small relative to other drivers, including population change, technology and many other aspects of socioeconomic development. Where have I heard that before?
In the UN Intergovernmental Panel on Climate Change’s 5th Assessment Report, released in 2013, that’s where. In the Working Group II volume, Chapter 10, the report concluded: “For most economic sectors the impact of climate change will be small relative to the impacts of other drivers. Changes in population, age, income, technology, relative prices, lifestyle, regulation, governance, and many other aspects of socioeconomic development will have an impact on the supply and demand of economic goods and services that is large relative to the impact of climate change.”
Yes, you read that right. The IPCC concluded, not very long ago, that while greenhouse gases have warmed the climate and will continue to do so, the effects will be small compared to pretty much every other driver of change in the century ahead. This is
the opposite of an “emergency” or “crisis.”
