By the early twentieth century, carbon emissions from fossil-fuel burning reached 1 billion tons a year. Automobiles, airplanes, and domestic and agricultural energy demands all contributed to the rising trend. In the 1950s, scientists used a new generation of equipment to confirm that carbon-dioxide concentrations were doubling and that this would have the effect of increased temperatures.

This excerpt primarily describes the

long-term effect of increasing carbon emissions.

long-term effect of decreasing temperatures.

short-term effect of decreasing the use of new technology.

short-term effect of increasing energy demands.

Im thinking either A. or D. Because the excerpt is talking about a long period of time but the increasing demand for energy caused the global emissions to rise, thats no doubt.
