Why are there different theories about the effects of global warming? a. there is no data to support global warming. b. global climate is complex, so changes in global climate are hard to predict. c. increased levels of carbon dioxide are offset by other changes. d. there has been a decrease of extreme weather. select the best answer from the choices provided a b c d

B. Global climate is complex, so changes in global climate are hard to predict.

 b. Global climate is complex, so changes in global climate are hard to predict.

Global warming is a phenomena of increase in the global temperature and the ill-effects associated with it like drying of the water body, melting of the glaciers, loss of biodiversity due to excessive heat present in the atmosphere and the trap heat liberated from the terrestrial land.

The prediction of the changes in the global climatic temperature is hard. As, the sunlight energy from the sun is trapped by the atmosphere as well as by the terrestrial land. Some of the trapped energy is reflected back to the space. This maintains the energy balance in earth. But due to the greenhouse effect and deforestation. The diatomic gases like carbon dioxide and carbon monoxide traps heat which makes the atmosphere warm. The abundance of gases in the atmosphere are responsible for the seasonal variations. Hence, making it difficult to predict the changes in the global climate.
