A strategy for ridding the world of VAD?

In July 2000, Time magazine announced that a potential solution to VAD had been found - 'Golden Rice' (Figure 8).

The name arises from the fact that the otherwise white grains of rice are given a golden colour by the presence of carotenoid compounds.

The announcement came at the height of the global controversy over genetically modified crops.

1.5 'Radiative forcing' as an agent of climate change

Since its first major report in 1990, the IPCC has used the concept of 'radiative forcing' as a simple measure of the importance of a potential climate change mechanism. The basic idea is straightforward. Any factor that disturbs the radiation balance at the top of the atmosphere has the potential to 'force' the global climate to change: it will either warm up or cool down until a balance is restored. The perturbation to the energy balance of the whole Earth-atmosphere system is called
