Rich nations blamed for global warming, but not for all the right reasons

As forecast, China has overtaken the U.S. in carbon-dioxide emissions due largely to China’s heavy reliance on coal. Another factor is its well-publicized population of 1.3 billion. But per-capita emissions are much higher in developed countries, where populations are exploding due to immigration. The U.S. already releases four times the carbon per-capita each year as China. And the U.S. population, which has been doubling every 40 years, is headed for one billion by the end of this century!

A number of climate-change observers see population control as essential to arresting global warming. They blame expansive immigration policies of the U.S., Canada and Europe for rising emissions because every immigrant from a tropical or semi-tropical climate requires huge additional amounts of carbon-based energy in the much-colder climate.

For example, the average annual per capita production of CO2 in Canada is 4.35 tons versus a mere .21 tons in Indonesia and 1.01 tons in Mexico. Even in highly industrialized Japan, where the climate is more moderate than in North America or Europe, production of CO2 per capita is only 2.34 tons or approximately 50% less than the same person's output in Canada.

Approximately 82,000,000 people have entered the U.S., Canada and Europe from warm climates in the last 40 years. Assuming only 3 additional tons of CO2 per person – a very conservative estimate – this transfer of population has added another 246,000,000 tons of greenhouse gases, annually, to the world's global-warming problems.

Global warming is a subset of the overpopulation problem ,” said Ric Oberlink of Californians for Population Stabilization. “If we had half as many people, we wouldn't have much of a climatic warming problem.

“Many have noted the disproportionate impact of America on greenhouse emissions and rightly called for reduced emissions. But it's hypocritical to say Americans consume too much and then say it doesn't matter how many Americans there are.”

Comments

Anyone who says the main problem is ‘this’ (with ‘this’ equalling overpopulation or consumption or whatever) is neglectful of multiplicative properties:
Environmental degradation = population size X consumption per capita X environmental degradation per unit consumption.
This equation says some rather helpful things, particularly when combined with other factors, like the law of diminishing returns.
Focusing in on population completely missed the driving relationship. Japan is not less carbon-intense because of a warmer climate - many European countries have a more moderate climate than Japan. Most of the southern United States are much warmer than Japan, and are far more carbon-intensive. Two factors mater, driving a measure that is far more important than population. Energy intensity of the economy (Japan is half that of the US, but China and India are way behind), and carbon intensity of energy generated (where China and the USA similarly bad, but Japan isn’t great either) drive carbon intensity of the economy. If the developing world continues to reach toward developed world standards of living without transforming their energy generation matrix and energy usage efficiency, everything the developed word does is measurement error. Under that scenario, every ‘warm coutnry’ citizen who comes to the developed world slows that process down.

A U.S. District Court judge ruled on June 27 that the Bureau of Land Management (BLM) and Forest Service both wrongly approved expansion of the West Elk coal mine in Somerset, Colo., because they failed to take into account the economic impacts greenhouse gas emissions from the mining would have.
 
The federal agencies said it was impossible to quantify such impacts, but the court pointed out a tool is...
