Heat waves cannot be felt or seen globally because they are specific localized weather phenomena that occur in particular regions or areas. Heat waves are characterized by prolonged periods of excessively hot weather, often accompanied by high humidity and stagnant atmospheric conditions. These conditions can lead to dangerous health impacts and affect various aspects of daily life.
However, the occurrence of a heat wave is limited to a specific geographical region or area. It is not a phenomenon that can be experienced or observed simultaneously across the entire globe. Different parts of the world experience heat waves at different times and with varying intensities, depending on local weather patterns and climatic conditions.
While the impacts of heat waves can be significant within the affected regions, they do not manifest as a global event that can be felt or seen by everyone worldwide simultaneously.
