After some time (long enough for many generations to pass, but not long enough for much evolution to occur), it is most likely that:killing them.19.Oxygen (O2) and nitrogen (N2) do not have much greenhouse effect, but several trace gases including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and various chlorofluorocarbons are important greenhouse gases. The primary mechanism by which these greenhouse gases warm the Earth is:A) Raising the atmospheric pressure, because squeezing air warms it, as we saw at the Redwoods.B) Experiencing chemical reactions with each other, which release energy.C) Absorbing some of the infrared radiation emitted from the Earth.D) Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse E) Making politicians mad, so they give speeches that heat the air.stops convection currents and so makes the air in the greenhouse warmer.20.The consensus of the world’s climate scientists, as generated by the UN-sponsored Intergovernmental Panel on Climate Change (IPCC), is that:primary cause of the ozone hole.
