The ozone layer acts as Earth's protective shield, blocking harmful ultraviolet radiation. While international efforts have helped curb ozone-depleting substances, the future recovery of the ozone layer faces new uncertainties due to global warming and human activities. The research highlights the dual ...
Heat waves (HWs) exert serious impacts on human health and the natural environment. With global warming, HW activities in many parts of the world have been intensifying during the past decades and are projected to pose increasingly severe threats to society in the future. In order to assess ...

The difference is that natural factors caused climate change in the early Holocene, whereas natural factors and human activities cause the present-day climate change. Global warming, in particular, is mainly due to human activities. The climate of the early Holocene is believed to have been ...
Soil could play a big role.Too much carbon dioxide (CO2) is in the air. It is one of the main causes of global warming. CO2 1 (come) from natural sources. It also comes from human activities. They include 2 (burn) fossil fuels(化石燃料) (coal, oil and gas). If there is too ...
