In calculations designed to help climate change-affected countries recoup damages for decades of carbon pollution from rich, carbon-rich nations, researchers calculated how many losses and advantages each country has inflicted on others.

To determine the precise economic impact that larger emitters have had on other countries, two Dartmouth scientists have just published research. The study, which was published on Tuesday in the journal Climatic Change, claims that the data might be used in court cases and in discussions concerning payments from wealthy countries that burn more coal, oil, and gas to poor countries harmed by emissions.

The new numbers quantify what scientists, public servants, and activists have long called an inequality in the national climate record, one that benefits rich nations from greenhouse gas production and the poor.

How Rich Country Cause Climate Harm To Poor Countries?

According to the data, the world’s largest carbon emitter, the United States, has cost other nations more than $1.9 trillion in climate-related damages between 1990 and 2014, including $310 billion for Brazil, $257 billion for India, $124 billion for Indonesia, $104 billion for Venezuela, and $74 billion for Nigeria. However, the U.S. has also benefitted from its carbon pollution to the tune of more than $183 billion.

“Do all countries look to the United States for restitution? Maybe,” said study co-author Justin Mankin, a climate scientist at Dartmouth College, an environmental health think-tank, all countries might look to resettle.

According to a new study, climate change has widened global inequality over the past 50 years, slowing growth in the poorest countries while undoubtedly enhancing income in some of the richest.

According to academics at Stanford University in California, the gap between the world’s poorest and richest nations is around 25% wider now than it would have been without global warming.

Developing countries have persuaded rich countries to promise them financial help in reducing carbon emissions going ahead, but they have so far not been able to gain compensation for any damage they have already done, a term referred to as “loss and damage” in Global Climate Discussion.

The talks brought a “veil of deniability” from major carbon emitters (the US and China) that their actions caused specific damage, said study leader Christopher Callahan, a climate impact researcher at Dartmouth.

Climate Change Impact and Solution

Adelle Thomas, a Bahamian climate scientist with climate analytics who wasn’t involved in the study, said: “Scientific studies such as this ground-breaking article reveal that high emitters no longer have a leg to stand on in evading their responsibility to address loss and harm.” Recent studies, according to her, “overwhelmingly and progressively reveal that loss and damage are already harming poor nations,” she stated.

According to the research, global warming had a negative effect on all 18 nations between 1961 and 2010 whose total historical emissions were less than 10 tons of CO2 per capita (nine tonnes), with a median drop of 27% in their GDP per capita compared to the scenario without rising temperatures.

With a median contribution to GDP per capita of 13%, global warming has benefited 14 of the 19 nations with cumulative emissions of over 300 tons of CO2 per capita (272 tonnes).

According to Khambule, “climate change helps no one in the long run. We shall see runaway climate change if it goes unchecked. The biggest polluters must immediately take action to cut their emissions.”

The urgency of the move away from fossil fuels and toward renewable energy demands that policymakers take climate change far more seriously than they presently do.
