in climatic conditions. Starting from monthly information, we compute the long-term trend of variation for precipitation and temperature by calculating for each year the average variation of the difference between the yearly change in the climate recorded in a given month (from 1990 onwards) and ...
In past years, GDP was used to measure a nation’s happiness, but the GDP cannot measure qualities such as family and friendship, moral values, happiness, or life purpose. Therefore, there is an increasing trend of using subjective measures of happiness beyond the classical income-based ...
