The resolution of the debate, and the recovery of the world oil market, will determine whether Mexico will become one of the richest or the most unstable of the oil exporters in the Third...

The measurement of global climate change poses grave difficulties for scientific enquiry and policy studies. Attention has so far focused on global warming and the concentration of greenhouse gases and a detailed examination has been made of the critical elements: carbon dioxide (C02), methane (CH4), nitrous oxide (N20) and chlorofluorocarbons (CFCs). Priority has now shifted to the refining of general circulation models (GCMs) and to the hypothesis testing that they allow. A new challenge must be met: to formulate measurements of the climate consequences of burning fossil fuels, and to identify the burdens that nations must shoulder to retard the process of global climate change. The conclusion is that policy recommendations...
