Part 6/7:

While the El Niño phenomenon has been noted for contributing to the rise in temperatures, the primary cause of this unprecedented warming is attributed to human activities. These include the burning of fossil fuels, deforestation, and other practices that intensify the greenhouse effect by trapping more heat in the atmosphere. Various factors have exacerbated the situation, such as the Hunga Tonga-Hunga Ha'apai volcanic eruption in January 2022 and a decline in maritime pollution that has historically reflected some solar heat back into space.
