A study by the Potsdam Institute for Climate Impact Research (PIK) published in the scientific journal "Nature" says that climate change could cause a decline of about 20% in gross domestic product (GDP) by 2050. Scientists said this figure will worsen if countries fail to meet emission reduction targets.
IPK researchers said their calculations were based on the prospect of countries like Germany meeting their emissions reduction goals. Currently, most countries appear unlikely to meet these targets, meaning that the financial impact may still be greater than the drastic damage predicted.

According to the study's calculations, the economic burden of climate change could reach 35.6 trillion euros per year, an amount six times higher than the estimated cost of limiting global temperatures to 2 degrees Celsius above pre-industrial levels.
Poorer regions will be more affected
The study points out that despite the damage affecting different regions at different levels, the poorest regions and those that contribute least to global warming will be hit hardest.
"Countries least responsible for climate change are projected to suffer an income loss that is 60% greater than higher income countries and 40% greater than higher emitting countries," said Anders Levermann, researcher at IPK.

Researchers have predicted, for example, that the economies of industrialized countries such as Germany and the United States will shrink by roughly 11% by the middle of this century. , while France 13%, even if successful climate protection actions are taken.
IPK scientists analyzed climate data collected over the past 40 years in more than 1,600 regions for their study. In their analysis, they excluded the cost of damages caused by natural disasters such as storms and fires, which have also been intensified by climate change and which will significantly increase damages./ DW
