Global warming: Need to sensitize general population

Population growth and global warming

When I was born in 1930, the human population of the world was a mere 2 billion. Today, it has already reached 6.8 billion, and is projected to reach 9.1 billion by 2050. That is unsustainable. It is slowly beginning to dawn on us that Global Warming is the result of increasing human CO2 emissions, and the more people there are in the world, the worse it will become. Ultimately, it is the sky t...

Global Warming and the Population Externality

We calculate the harm a birth imposes on others when greenhouse gas emissions are a problem and a cap limits emissions damage. This negative population externality, which equals the corrective Pigovian tax on having a child, is substantial in calibrations. In our base case, the Pigovian tax is 21 percent of a parent’s lifetime income in steady state and 5 percent of lifetime income immediately ...

Global Warming Policy and Distributional Effects: A General Equilibrium Analysis1

This paper analyzes the impact of carbon taxes on the Japanese economy using an applied/computable general equilibrium model. This analysis sheds light on both the efficiency and the equity issues of these policies. The study shows that some alleviation measures, e.g. tax differentiation, might be required to ease the damages caused to energy intensive industries. Moreover, considering the regr...

Global warming

The role of General Circulation Models (GCMs) has become predominantly important as the practical interest in regional impacts from anthropogenic greenhouse gases such as carbon dioxide (CO2) grows. This first report documents the quality of GCMs as a tool for describing and predicting ‘global warming’ and the related geographical pattern of climate change from the CO2 added to Earth’s atmosphere.
