Nevertheless, their impacts on nations, farm belts, and coasts is profound, as the difference between 51 North in Labrador and England demonstrates. These currents must be named as strategic indices. Another strategic index of climate change is phonological phenomena, for example, the date that a particular plant species flowers or a particular species of bird migrates to or from a place. D.C. The dates that plants flower and seeds ripen, however, are the footings of farming and civilization. This final index is, of course, a biological response to weather.
Heat waves have a special impact on the generation of electricity for air conditioning.
Winter cold also affects its generation because electricity is used for some heating. Frost kills crops. So the extremes of temperature are crucial. The five indices listed above are the strategic ones for agencies to monitor and scientists to predict so that the impacts of climate change can be assessed and adaptations can be made. Although these indices are crucial for estimating impacts and adapta- tions, they cannot now be computed responsibly.
