Tropical regions in several tropical regions of the world are also increasing due to the rainfall of most of the tropical regions (Legates et al. 1990). Some tropical rainforests show an increase in forest area as rainfall increases and the average temperature rises. In these stable tropical environments, it enables greater growth or biodiversity and tropical change (Petchey et al., 1999). As this temperature change increases rapidly, many organisms have to change their reactions earlier than they were needed before.
Extreme weather, extreme events, tropical cyclones: data analysis of extreme events from 1960 to 2010 showed that both drought and heat wave increased simultaneously. Since 1980, extremely humid or dry events are increasing during the monsoon season. According to the forecast, the occurrence frequency and severity of specific abnormal weather such as heat wave may increase. Changes in the ecosystem, changes in the nature of the ocean: In terrestrial ecosystems, the early days of spring events, and extreme upward changes in the range of animals and plants are associated with the recent high confidence in global warming. Most ecosystems are expected to be affected by higher atmospheric CO2 levels and higher global temperatures. Expansion of the subtropical desert may be related to global warming. Physical effects of global warming on the ocean include an increase in acidity and a drop in oxygen concentration (ocean deoxidation).
Due to natural weather changes it is difficult to condemn global warming due to certain extreme weather events such as hot weather, floods causing floods, droughts, etc. However, climate theory and models predict that global warming will increase the frequency and intensity of certain extreme phenomena. In other words, the warm world like a scorpion with a load has more "heat waves" or "strong storms" than the undisturbed world. Therefore, scientists can estimate only a small part of a specific type of risk. Human Responsible Events This section introduces examples of extreme phenomena observed in recent decades, but these extreme phenomena are consistent with the impact of global warming.
