This loss amounts particularly affects tropical regions and low-income countries

A study published by the University of Delaware shows that climate change will cause a 6.3% loss in global gross domestic product by 2022, with a more significant impact on developing country economies. The study points out that the difference between the weighted and unweighted impact reflects the uneven distribution of losses, with more severe consequences in densely populated countries with lower incomes.

In addition to direct impacts on agriculture, energy and productivity, climate change has had indirect impacts on international trade and investment. The study's authors, including Professor James Rising of the University of Delaware, point out that "most of the burden of climate change falls on poor countries", according to Digi24. 

The countries most affected are those in Southeast Asia and Southern Africa, with GDP losses of 14.1% and 11.2% respectively. In contrast, some developed countries, particularly in Northern Europe, have seen GDP increases due to milder winters. However, the study warns that these benefits could be reversed as drier summers offset warmer winters.

The results of the study come just ahead of the 28th Conference of the Parties (COP 28) on climate change, scheduled to take place in Dubai, where one of the major stakes is the adoption of a framework for new UN funds to help poor countries cope with the consequences of climate change.
