A study has found that the costs of climate damage could reach $38 trillion annually by 2050. EcoWatch, established in 2005 in Ohio, is a digital platform that focuses on sharing scientifically accurate information about environmental topics, including problems, reasons, and potential solutions.
A recent study conducted by Germany's Potsdam Institute for Climate Impact Research (PIK) predicts that the global costs of climate change damage will reach around $38 trillion per year by the year 2050.
The consequences will be experienced globally, but will have the greatest impact on countries that have made the smallest contributions to the climate crisis.
The study brings attention to the unfairness of climate change impacts, showing that damages will be widespread but most severe in countries located in the tropics due to their already warm climates. These countries are projected to experience the greatest harm from further temperature increases, despite being the least responsible for causing climate change. They are expected to face income loss that is 60% higher than wealthier countries and 40% higher than countries with higher emissions. Additionally, these countries have fewer resources to adapt to the impacts of climate change, as stated by Anders Levermann, co-author of the study and head of the research department at PIK, in a press release.
A research paper titled "The financial impact of climate change" was released in the publication Nature.
According to a study co-authored by climate scientist and economist Leonie Wenz from PIK, it is predicted that climate change will lead to significant economic losses in the next 25 years in nearly all countries, including highly developed ones like Germany, the U.S., and France. The study suggests that median incomes could decrease by 11% in Germany and the U.S., and by 13% in France.
According to Reuters, it is highly likely that the consequences of burning fossil fuels will become more severe as humans keep doing so.
The current damages we are experiencing are a direct result of emissions from the past. To prevent further damage, we need to increase our efforts in adaptation. It is crucial that we significantly reduce our emissions immediately to prevent even greater economic losses in the future, which could reach up to 60% globally by 2100. This highlights the importance of investing in climate protection, as it is more cost-effective compared to the consequences of inaction, including loss of life and biodiversity. Wenz emphasized these points in the press release.
The researchers utilized empirical models and climate simulations to analyze the long-term effects of climate change on the economy. By studying data from over 1,600 regions worldwide over a 40-year period, they evaluated how changes in climate conditions could impact future economic growth.
The study predicts significant decreases in income for most regions, particularly North America and Europe, with South Asia and Africa experiencing the most severe effects. These reductions are attributed to climate change's influence on factors like agricultural yields, labor productivity, and infrastructure, according to Maximilian Kotz, a climate scientist at PIK and the study's lead author, in a press release.
Experts predict that economic damages could reach as high as $59 trillion by the middle of the century due to increasing temperatures, changes in rainfall patterns, and fluctuations in temperature. The costs could be further amplified by extreme weather events such as wildfires and storms.
According to the researchers, the global economy is on track to experience a 19% decrease in income over the next 26 years, regardless of what actions are taken to reduce emissions. The economic losses from this decrease are already greater than the costs of measures needed to limit global warming to 2°C by six times in the short term, and will continue to diverge significantly depending on future emission choices.
Levermann highlighted the importance of quickly transitioning to alternative energy sources and moving away from using fossil fuels.
The decision is in our hands to make a change in the structure towards using renewable energy, which is necessary for our safety and can also help us save money. Continuing on our current path will result in severe consequences. To stabilize the planet's temperature, we must cease the burning of oil, gas, and coal, as mentioned by Levermann in the press release.
Wenz was surprised by how severe the disparities in the impacts were.
Wenz expressed his devastation at the findings, as reported by The Guardian. He mentioned that while he is accustomed to his work not always leading to positive societal outcomes, he was surprised by the extent of the damages. The level of inequality uncovered was particularly shocking to him.
