According to a ground-breaking study published in Nature Climate Change, the wealthiest 10% drive two-thirds of global heating since 1990. This study, which was completed on May 10, 2025, demonstrates how the poorest areas close to the equator have been disproportionately affected by extreme weather events like heatwaves and droughts, which the consumption and investment decisions of the wealthy have exacerbated. The report makes a strong case for targeted climate policies, such as wealth taxes and climate finance, to address this glaring inequity by connecting wealth-based emissions to particular climate impacts. It exposes a crucial reality: the way of life of the wealthy directly adds to the misery of those who are least prepared to deal with climate change.
Quantifying Wealth’s Role in Climate Breakdown
The study quantifying the relationship between economic disparity and accountability for global warming represents a significant breakthrough in climate research. Researchers incorporated wealth-based greenhouse gas emissions data into climate modelling frameworks to evaluate changes in global temperatures and extreme weather events from 1990 to 2019. They discovered that the emissions of the wealthiest 10%, classified as those who earn more than €42,980 (£36,472) a year, were responsible for 65% of the 0.61°C increase in the world mean temperature in 2020 compared to 1990. With a median income of £37,430, this category comprises more than 50% of full-time UK workers. 20% of global warming was caused by the wealthiest 1% (those with incomes over €147,200), whilst 8% was caused by the top 0.1% (those with incomes over €537,770). These numbers highlight the elite’s disproportionate contribution to climate change.

Disproportionate Emissions and Hypothetical Scenarios
The study of the wealthiest 10% drive two-thirds of global heating draws attention to the glaring differences in carbon contributions between socioeconomic brackets. The top 1% and 0.1% contributed 20 and 76 times higher emissions, respectively, while the wealthiest 10% emitted 6.5 times more than the world average. The researchers created fictitious situations to show the effects of this imbalance. Additional warming since 1990 would have been negligible if the world’s population’s emissions had been at the level of the poorest 50%. Global temperatures would have increased by 2.9°C if everyone had emitted at the same rate as the top 10%, 6.7°C if the top 1%, and an unsustainable 12.2°C if the top 0.1%. “The world would have seen minimal additional warming if everyone had emitted like the bottom 50%,” co-author Carl-Friedrich Schleussner stressed. These scenarios demonstrate how wealthy people’s purchasing habits have exacerbated climate breakdown to a significantly greater extent than equitable emissions would have.
Impacts on Vulnerable Regions
The poorest areas of the world, especially those close to the equator, are most severely affected by this emissions discrepancy. These nations, which already struggle with scarce resources, are facing more severe heat waves, droughts, and increasing temperatures due to emissions from the world’s elite. “We can directly link [climate impacts] to our lifestyle and investment choices, which in turn are linked to wealth,” said Sarah SchoÈngart, the study’s primary author. These severe weather conditions worsen poverty and food insecurity by interfering with livelihoods, crops, and water supply. A significant inequity is shown when the wealthiest countries and people, frequently found in temperate zones, are better able to adapt. The study emphasises how urgently climate funding is needed to help vulnerable countries adapt to these effects, which they did not cause but must now face.

Policy Implications and Climate Justice
As the wealthiest 10% drive two-thirds of global heating, the results offer a solid empirical foundation for legislative actions meant to rectify this disparity. The researchers support wealth taxes and more payments from rich countries to climate finance, among other climate measures that target top polluters. “Climate action that ignores the disproportionate responsibilities of the wealthiest risks missing one of the most powerful levers we have to reduce future harm,” Schleussner emphasised. Nonetheless, there is still opposition, since nations like the US and the UK are reducing their climate funding pledges. Global efforts to lessen the harshest effects of climate breakdown on developing countries are hampered by this reaction. The study emphasises that the wealthy have a large portion of the responsibility and advocates for more social acceptability of climate action. The study makes a moral and scientific case for redistributive policies to finance adaptation and mitigation in the most impacted areas by connecting some climatic impacts to the emissions of the wealthy.
The study concludes by highlighting climate inequality: two-thirds of global warming since 1990 has been caused by the wealthiest 10% of people, which has had a disastrous impact on the world’s poorest regions. Given the disproportionate contributions from the richest 1% and 0.1%, the necessity for targeted climate policy is evident. This disparity may be rectified by wealth taxes and strong climate finance systems, which would guarantee that those most accountable for the problem assist in lessening its impact on the most vulnerable. A sustainable future and climate justice depend on recognising and addressing this disparity as the world struggles with growing climate issues.

Hallo,
mich würde die original Studie sehr interessieren. Allerdings ist oben nur die Seite von Nature Climate Change verlinkt und der Artikel enthält auch nicht den vollständigen Titel der Studie.
Im Hinblick darauf, dass es viele Menschen gibt, die die Auswirkungen des Klimawandels an sich und/oder ihren eigenen Beitrag dazu abstreiten, finde ich es sehr wichtig sauber wissenschaftlich zu belegen und Quellen immer nachvollziehbar anzuheben. Ich würde mich daher freuen, noch einen Hinweis zur Primärquelle zu erhalten. Vielen Dank!
