Catastrophic Anthropogenic Global Warming (global climate destruction caused by human emissions of greenhouse gasses). The struggle for life on earth. Mass Extinction - Definition. A significant proportion of species become extinct (between 30% and 95%) . The extinctions operate across a wide range of environments and . Overview. Extinctions are as important in the history of life as are the evolution of new species. Explaining extinctions is just as challenging a scientific question as explaining the evolution of new species. The sixth . m. ass . e. xtinction. Objectives. Define . extinction..

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate.
