Scientists have pointed to a common rule to align our calendar year with Earth’s rotation: If the year is divisible by 100, but not divisible by 400, a leap year is skipped, according to airandspace.si.edu. The year 2000 was a leap year, for example, airands...
Leap years are years where an additional day is added to the end of the shortest month, February. The extra day, February 29, is generally referred to asleap day. Leap years have366 daysrather than the standard365 daysand occur almost every four years. Why do we Have a Leap Year? Leap...

The RE influence, on the one hand, and the increasing cost of natural gas electricity generation, on the other hand, were responsible for the early elimination of gas-fired plants from the generation mix as of 2044, with a reduced role for coal-powered plants. The improvement in the share...
Only a year later, the Population Division team described the medium projection as the most likely “based on an implicit assumption of a continuation of existing policies” [36], p. 2. It could be argued that the probabilistic projections brought a more fatalistic outlook, with the language ...
