Since the beginning of the 21st century, the threat posed by climate change to mankind has not been underestimated. Global warming has caused glaciers to melt and sea levels to rise. According to a study, the sea level in Macao from 1993-2012 is 1.1 times the global average. In the future, the sea level in Macao is expected to rise 20 percent faster than the global average. In addition, Macao is located at low latitude, facing the South China Sea, exposed to the sea,, the monsoon, and temperature changes. In Macao, summer and winter are mainly divided into two short seasons, the spring and autumn period. In recent years, however, the weather in Macao has begun to turn cold in November. Cold air from the north has formed into what is known as a cold water. In the hours before and after a cold wave, temperatures will drop down to about 10 degrees. One of the biggest impacts of global warming on public health is to foster the growth of disease vectors. Mosquitoes are carriers of dengue, Japanese encephalitis, Zika and other diseases. According to the records, cases of dengue fever in Macao occur in late summer and winter, which is due to the time temperature, rainfall, and humidity. The warming of the climate will lead to an earlier summer, a prolonged winter, an increase in mosquito breeding and disease leading to more cases of dengue fever. Thus, the world is facing a serious and urgent task to achieve sustainable development so we can relieve global warming.
Climate change is ushering in a new era characterized by increasingly frequent and intense heat waves, presenting profound challenges to ecosystems, communities, and individuals around the world. I will talk about the changing nature of heat waves in the context of climate change, multifaceted impacts, and the adaptive
