The scientific view is that the increase in global temperature should not exceed 2 °C above pre- industrial level. If the global temperature increases beyond 3 °C above the pre-industrial level, what can be its possible impact/impacts on the world?
I. Terrestrial biosphere tends toward a net carbon source.
II. Widespread coral mortality will occur.
III. All the global wetlands will permanently disappear.
IV. Cultivation of cereals will not be possible anywhere in the world.

Impacts of Global Temperature Rise Beyond 3 °C
The potential impacts of exceeding a global temperature increase of 3 °C above pre-industrial levels are significant and multifaceted. Here are the key consequences:
I. Terrestrial Biosphere as a Carbon Source
- The increase in temperature can lead to stress on forests and ecosystems, causing them to release more carbon dioxide than they absorb.
- This shift can exacerbate climate change, creating a feedback loop that accelerates global warming.
II. Widespread Coral Mortality
- Coral reefs are highly sensitive to temperature changes; a rise of just 1-2 °C can lead to bleaching.
- Beyond 3 °C, significant coral mortality is expected, resulting in the loss of biodiversity and marine ecosystems.
III. Global Wetlands Disappearance
- Wetlands are crucial for biodiversity and act as natural buffers against climate change.
- Increased temperatures can lead to alterations in rainfall patterns, potentially causing all global wetlands to shrink or disappear permanently.
IV. Challenges in Cereal Cultivation
- Higher temperatures, coupled with unpredictable weather patterns, will severely affect agriculture.
- Many regions may find it increasingly difficult to cultivate cereals, leading to food insecurity worldwide.
In conclusion, the combined effects of temperature increases beyond 3 °C would result in severe ecological, agricultural, and climatic challenges, making options I, II, III, and IV all plausible and concerning consequences. Therefore, the correct answer is option 'D'.
