Climate Trends: Warming Trends and Variations

Climatologists generally agree that there is accumulating evidence that a warming trend has been occurring since the mid-1960s. There are rather distinct seasonal and regional climate variations in the lower 48 states of the United States. Livezey and Smith determined that the average national warming trend has been 0.0151F per year. Since 1964, this implies that average annual temperature has increased by approximately one-half of one degree. (more…)

Climate Impacts on Energy Demand

climate changes energy
Energy is consumed by various segments of the economy, including households, commercial establishments, manufacturing enterprises, and electric power generators. Only a portion of total energy demand is sensitive to temperature changes. (more…)

Sensitivity of Energy Demand to Temperature Changes

Here, the sensitivity of energy demand to climate is measured two ways. The first method uses elasticities that provide simple summary measures of how departures from normal temperatures affect energy consumption. The second approach, reported in the following section, uses econometric simulation to estimate how climate changes affect energy demand. (more…)
