Dartmouth study links past U.S. greenhouse gas emissions to global economic damages

The United States and China, the world’s largest emitters, account for more than $ 1.8 trillion in global revenue from 1990 to 2014, according to a recent study linking global gas emissions to economic crisis. for the season. among others. The report may strengthen the scientific basis on the legal implications of global warming.

A study by Dartmouth College, published in the journal Climatic Change, linked global warming to loss and gains in the domestic resources of 143 countries where data is available. It found that only five of the world’s greenhouse gas emissions spent $ 6 trillion in global warming from 1990 to 2014. The economic damage caused by Russia, India and Brazil exceeds $ 500 billion at the time. of this. three countries emitter.

“This study provides the answer to the question of whether there is scientific evidence on climate change. The answer is yes, “said Christopher Callahan, a PhD student at Dartmouth and co-author of the study, in his statement.

The United States, for example, spent $ 34 billion in the Philippines during the period 1990 to 2014, in response to US emissions.

The researchers said the U.S. atmosphere emits a change of 0.054 degrees Celsius during the Middle Ages at that time. This caused the average temperature of 0.04 in Indonesia to change over the same period, a change that comes from air emissions from the United States.

“These changes may seem small, but because Indonesia is a warm, tropical country, global warming is seriously damaging its economy,” Callahan said. “Any increase in 1 degree their temperature reduces economic growth by 1.6 percent.”

The combined figures showed that the United States reduced Indonesia’s economic growth by 0.065 percent annually during the same period. And, Callahan said, because Indonesia is the most populous country with the largest economy, even a gradual decline in economic growth adds to the absolute maximum number: a loss of $ 124 billion at this time.

The question of the role of climate change is a matter of increasing crime around the world.

Cities and countries have sued global oil company ExxonMobil for failing to disclose to investors the risk of climate change. Various environmental groups have taken Shell to court in the Netherlands. And a Peruvian farmer is suing RWE, saying that Germany’s largest weapon, which scientists say produced 0.47 percent of carbon and methane emissions worldwide between 1751 and 2010, should pay its share to protect a small town in Peru. mountains.

In the meantime, many developing nations are demanding that rich countries pay for the “waste and waste” that they have accumulated over the years.

“For the first time, we have been able to demonstrate a clear and measurable link between the emissions of certain countries and the economic downturns that other countries have experienced,” Callahan said. “This is about the fault of one country going to another, not because of global warming.”

White House lieutenant John F. Kerry said at the end of a climate conference in Glasgow that he understood the compulsion to return and spend money but there was no way to spend money.

The Dartmouth team believes their research “undermines the notion that climate change is a ‘practical problem,’ in which no single state can affect the effects of global warming,” said Justin Mankin, an assistant professor of geography at the organization. Dartmouth is the lead researcher for this study.

Some studies have relied on one or two aspects of the Dartmouth team’s three approaches.

“Scientists have already described the economic history of global warming, showing that climate change has benefited cold, rich countries and harmed tropical, poor countries,” Callahan said. But, he said, he did not count on the guilt of the private producers. A recent study identified the potential global impact of global warming but did not take into account the economic impact of climate change.

“Our work can be seen as combining two different types of work into one integrated system,” he said.
