A new study showed that global warming has increased the world’s economic gap since the 1960s.

The work,  published in “Proceedings of the National Academy of Sciences” on Monday revealed that the temperature change triggered by the increase in the atmosphere’s greenhouse gas’ concentration may enrich chillier nations such as Norway and slow the development in warmer countries such as Nigeria.

“Our results show that most of the poorest countries on Earth are considerably poorer than they would have been without global warming,” Stanford University climate scientist  Noah Diffenbaugh, the lead author of the study explained.

The researchers analyzed temperature measurement and the annual GDPs of 165 countries to estimate the impact of temperature fluctuation on economic growth for almost 50 years (1961-2010).

They also discovered that global warming decreased individual’s wealth in the world’s poorest nations between 17 percent and 30 percent.

The gap between the wealthiest and the most impoverished stood at 25 percent bigger than that without climate change, the research described.

“We can’t assume that what’s happening somewhere across the globe isn’t going to have impacts in richer countries,” David Waskow of the World Resources Institute told CNN.

According to Marshall Burke, professor assistant at Earth System Science at Stanford and also the research co-author, an average temperature will boost productivity and health both in people and crops.

“Crops are more productive, people are healthier, and we are more productive at work when temperatures are neither too hot nor too cold. That means that in cold countries, a little bit of warming can help. The opposite is true in places that are already hot,” Burke said.

Climate change decreases global GDPs

Gross Domestic Product (GDP), defined as the numbers of products and services produced in a country, is often used as the growth’s indicator. According to the TIME report in 2016, global warming could severely impact the world’s overall GDPs.

Even, the global GDPs are predicted to decline by 23 percent in 2100 due to the air temperature affecting the output of various industries. As global warming can lead to a production’s disruption, the GDPs will be affected.

A survey carried out by the Carbon Disclosure Project showed the impact of climate change on production output. As many as 2,000 companies surveyed, 44 percent of them had their production disrupted by drought and rains. While 31 percent of the companies admitted paying for extra production costs.

Climate change can change working hours and reduce productivity

The Stanford research echoed earlier research conducted by the United Nations (U.N) in 2016. As Bloomberg reported, the study revealed that the global cost to tackle the impact of global warming could reach more than $ 2 trillion in 2030.

As many as 43 countries, mainly in Asia (including Indonesia, Malaysia, and China) will suffer a stagnant growth due to a warmer climate.  Tord Kjellstrom, an Environment and Health Director of a New Zealand-based International Trust, estimated that China’s GDP will drop 1 percent and Indonesia 6 percent in 2030.

Extreme hot weather in Southeast Asia will cut annual working hours by 15 percent-20 percent, and the figure may double in 2050 if climate change is not appropriately addressed, based on a study published on Asia-Pacific Journal of Public Health.

Research from the Energy Policy Institute at the University of Chicago (EPIC)  showed that the value of production output was down three percent for every degree above the average temperature in India.

“Air conditioning is expensive, and poor countries are unlikely to move to universal cooling anytime soon. However, if cooling the workplace doesn’t prevent people from skipping work, then adapting to hotter temperatures will be difficult even in richer countries,” Anant Sudarshan, the South-Asia Director of EPIC, said
