In their latest report on climate change, officials at the U.N. Intergovernmental Panel on Climate Change (IPCC) once again fail to address important developments in climate science that conflict with their narrative of fear. (See: Threat from global warming heightened in latest U.N. report)
Specifically, the IPCC press release ignores: (1) the growing divergence between observed global temperatures and the computer model projections on which scary climate impact assessments depend, (2) 20 recent studies indicating that climate sensitivity (an estimate of how much warming results from a given increase in atmospheric greenhouse gas concentrations) is about 40 percent less than the mean estimate of IPCC models, and (3) studies indicating that the three main climate doomsday scenarios — ocean circulation shutdown, rapid ice sheet disintegration, runaway warming from melting frozen methane deposits — are scientifically implausible (for references, see pp. 23-26 of CEI’s comment letter on the social cost of carbon).
Worse, as usual, IPCC officials say nary a word about risks of carbon mitigation policies. Those include:
- The public health and welfare risks of carbon rationing schemes or taxes that raise business and energy costs.
- The economic, fiscal, and energy security risks of anti-fracking climate policies that endanger the shale revolution.
- The economic development risks of coal power plant bans and other policies that limit poor countries’ access to affordable energy.
- The risks to international peace and stability of impeding developing country economic growth through carbon caps or taxes and carbon-tariff protectionism.
- The risks to scientific integrity when government is both chief funder of climate research and chief beneficiary of a “consensus” supporting more regulation and higher taxes.
- The risk to the democratic process when governments promote “consensus” climatology to justify bypassing legislatures and marginalizing opponents as “anti-science.”
