“But while the IPCC chooses to look the other way, the scientific evidence supporting low equilibrium climate sensitivity continues to pile up…. This is all around good news, for it means that we can focus more on expanding energy access (via fossil fuels) around the world rather than curtail our energy growth.”

There are basically three key parameters that determine the pace and magnitude of future climate change: 1) how much carbon are we going to emit, 2) what percentage of those emissions will remain in the atmosphere (as opposed to being taken up by the biosphere), and 3) how much will the climate warm as a result of what remains in the atmosphere. We understand these things a lot better than we often let on.

The first parameter seems difficult to assess on timescales that exceed a couple of decades.…

“The chief reason BC is not an appropriate ‘model’ for the U.S. is that the province’s geology, climate, and electric supply system are dissimilar to those of most American states. BC’s peculiar electricity fuel mix sharply limits the damage that a $30/ton carbon tax can do to the province’s economy. Nearly all of BC’s base load electricity is zero-carbon hydropower…. Natural gas is the only part of BC’s electric supply system subject to the tax …. and generates less than 6% of BC’s electricity.”

To persuade Americans — especially conservatives and libertarians — that a carbon tax can “work” (reduce emissions) without harming the economy, some proponents tout British Columbia’s carbon tax, enacted in May 2008. How relevant is the British Columbia (BC) “model” to U.S. climate and tax policy debates?…

“The most important benefit of population size and growth is the increase it brings to the stock of useful knowledge. Minds matter economically as much as, or more than, hands or mouths. Progress is limited largely by the availability of trained workers. The more people who enter our population by birth or immigration, the faster will be the rate of progress of our material and cultural civilization.”

Population and Progress

With respect to population growth: A dozen competent statistical studies, starting in 1967 with an analysis by Nobel prizewinner Simon Kuznets, agree that there is no negative statistical relationship between economic growth and population growth. There is strong reason to believe that more people have a positive effect in the long run.

Population growth does not lower the standard of living – all the evidence agrees.…

“I view my 40+ year career as progressions on a common theme; understanding (and promoting) the role of free markets and technology innovation one to the other, both to improve humankind’s’ lot.”

MasterResource from time to time conducts interviews with leading free-market scholars (see Ken Green here). This two-part interview with Tom Tanton continues tomorrow.

Q. Let’s start with your current position and responsibilities.

TT: I’m currently Director of Science and Technology Assessment at the Energy and Environment Legal Institute (EELI). I’m also President of my consulting firm T² and Associates, which stands for “Trust in Technology” not my initials.

EELI is focused on strategic litigation, such as testing the constitutionality of the renewable portfolio standard in Colorado, and on increasing government transparency through Freedom of Information Act requests and litigation.…
