Climate change UPSC NOTE

 Unequal economic impacts of climate change around the world

  • The global economy is expected to lose about 19% income in the next 25 years due to climate change, with countries least responsible for the problem and having minimum resources to adapt to impacts suffering the most according to a new study published

  • South Asia and Africa will be strongly affected

  • The researcher says the global income loss could vary between 11% and 29%, depending on different climate scenarios and uncertainties in the data

  • The countries least responsible for climate change are predicted to suffer income loss that is 60% greater than the higher-income countries and 40% greater than higher-emission countries

  • Climate science says the world needs to slash CO2 emissions by 43% by 2030 to limit the average temperature rise to 1.5 degrees Celsius, the guardrail to prevent worsening of climate impacts

Why countries in the tropics will suffer the most?

  • While most regions in the world are expected to suffer economically due to these changes, the regions near the poles might see some benefits due to less temperature variability.

  • On the other hand, the hardest-hit regions will likely be those closer to the equator, which historically have contributed less to global emissions and currently have lower incomes.

  • Countries in the tropics will suffer the most because they are already warmer. 

  • Further temperature increases will therefore be most harmful there
