However, it is much easier to
figure out what happens when you add more radiative
gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the altitude of the effective radiating level and hence means the
emission is occurring from a lower - temperature layer, leading to a reduction of
emission that is eventually remedied by the atmosphere heating up so that radiative balance at the top - of - the - atmosphere is restored.
These
figures do not take into account the recent long - term energy strategy of the European Union (EU), which proposes that by 2020, EU consumption of renewables will increase to 20 percent of total energy use; the proportion of biofuels used in transport will increase to 10 percent; and EU greenhouse
gas emissions will be reduced to 20 percent below 1990 levels (European Union, 2007).

The sources of uncertainty are many, including the trajectory of greenhouse

Figure 13.2).
However, the amount of warming caused by human greenhouse
