Document Summary
Major climate reports describes a strong risk of crisis as early as 2040. If greenhouse gas emissions continue at current rate, atmosphere will warm by 2. 7 f, inundating coastlines and intensifying droughts and poverty. Transforming world economy within few years would cost trillion, but politically unlikely. Coal: world coal association disputes ending coal use, should invest in carbon capture technology, but currently too expensive for commercial use. However, could allow coal to continue to be widely used. If we go past this mark, all coral reefs would die. The world is already more than halfway to the 2. 7-degree mark. In oceans, most fisheries are shrinking because of overharvesting: conservation biology: integrates ecology, physiology, molecular biology, genetics, and evolutionary biology to conserve biological diversity at all levels. 56. 1: human activities threaten earth"s biodiversity: high rate of extinction is responsible for biodiversity crisis, more than 1000 species extinct in last 400 years.
