Compound drought and heatwaves (CDHWs) can cause significant socio-economic and ecological impacts. A better understanding of historical spatiotemporal changes of Australian CDHWs and their underlying physical mechanisms can help improve their predictability. We analyse changes in the extended...

The Next Step for Climate Change Policy

The third Conference of the Parties to the United Nations Framework Convention on Climate Change will be held in Kyoto in early December. These upcoming negotiations, aimed at reducing future emissions of greenhouse gases, are almost certain to accomplish nothing. Failure is likely because the...

Global Emissions Trading: Prospects and Pitfalls

The next major round of international negotiations on controlling global climate change is to be held later this year in Kyoto. The focus of talks to date has been on policies to reduce worldwide carbon dioxide emissions to 1990 levels and hold them there. A proposal by the United States would...

In November 2000, just after the presidential elections in the United States, negotiators will meet in The Hague at the sixth meeting of the Conference of the Parties (COP6) to the United Nations Framework Convention on Climate Change (UNFCCC). By then, it will have been almost three years since...

Exact optimal paths are calculated for a closed economy with human-made capital, non-renewable resource depletion and exogenous technical progress in production, hyperbolic utility discounting, and (possibly) hyperbolic technical progress. On its optimal path, generally, welfare-equivalent...

We construct a hybrid, economic indicator of the sustainability of global well-being, which is more inclusive than existing indicators and incorporates an environmentally pessimistic, physical constraint on global warming. Our methodology extends the World Bank's Adjusted Net Saving (ANS)...

We build a theoretical model of optimal, closed-economy growth including inputs of human and knowledge capital and growing natural resources, and give three approximate calibrations of it to global economic growth during 1995-2014. We thereby show that the World Bank's Adjusted Net Saving...
