Subject Index Summary
Response of Marine Plants to Changes in Temperature: According to the IPCC, CO2-induced global warming will be net harmful to the world's marine species. One consequence of such harm, is a projected decline in ocean productivity. And in light of what the IPCC frequently refers to as the unprecedented modern rise in global temperature, it might reasonably be expected there should already be signs of a major negative impact on oceanic productivity. Yet the studies highlighted in this summary yield little evidence in support of the IPCC point of view.
