Climate change has already increased global inequality. It can only get worse

Scientists have long predicted that the warmer temperatures caused by climate change has the greatest impact on the poorest, the most vulnerable people in the world. New research now shows that is what has happened in recent decades. A study published Monday in the Proceedings of the National Academy of Sciences found that to have probably performed in most poor countries, higher temperatures, more than 90% of the reduced economic output, compared to a world without global warming. Meanwhile, the effect is less dramatic, also potentially benefit the wealthiest nations-with some of the highest temperatures. “We are not the argument that global warming created inequality,” said Noah S. Diffenbaugh, author of the study and a professor at Stanford University who has studied climate change. But the “global warming has put a stop to the improvement.” The countries most likely to have cost as little fact that he lost due to warmer temperatures, contributing to the problem, he adds. The new study builds on previous research. A study in 2015 in the journal Nature states that the average income in the poorest countries will fall 75% by 2100 compared to a world without heating, while some experience of the richest gains income countries. And a landmark report published last autumn by the Intergovernmental Panel on Climate Change (IPCC), the body of climate science of the United Nations, showed that if global temperatures rise more than 1.5 ° C by the end of the century, probably poorer countries will face critical challenges, including the destruction of communities and millions of premature deaths. “They will be most affected, they suffer disproportionately, as they already are,” said Mary Robinson, former UN Special Envoy on Climate Change and a former president of Ireland, said that since the beginning of the IPCC report. Before any of this research has been published, Aria has the policy seeks the problem of the poorest countries deal with the worst effects of rising temperatures, by contrast, they charge less. The first attempts of global warming on the world stage addressing contain different expectations for the reduction of emissions in relation to the level of each country’s development. plus additional space poorest countries, while the richest bore responsibility. But in a sense, with the United States has failed approach and by extension the rest of the world as it helped fuel the popular conservative narrative that pays Washington for climate protection too, while the poorest countries are increasingly farther away do less. The Republican conversation has a real impact. uncompromising differences between the requirements for rich and poor countries have softened in recent years, for a lighter version of what the climate change policy as a reference “common but differentiated responsibilities”. The principle of climate agreement incorporated to 1992, including the Paris agreement landmark year, suggests that richer countries should carry more weight in the fight against climate change, but is vague, what does that mean for the practical policy . Many of the countries of the world have foul development. “This creates a problem somewhere else,” Abdur Rouf Talukder, Bangladesh Secretary of Finance, told TIME earlier this month. “We are giving more money for adaptation, because we have to live.” GDP per capita of Bangladesh’s 12% lower due to global warming, by 2010 than would have been otherwise in two decades, according to the study published Monday. The effect is even the countries of the Sahara, including Sudan, Burkina Faso and Niger dramatic elsewhere, to the south of the place where climate change in Africa in particular has prompted more per capita GDP of less than 20% it would be absent climate change. Higher temperatures affect economic performance in a variety of ways. For example, increases the productivity of work with extreme heat, Cultures lower yields and cognitive functions generate declines. “There are a number of ways from the temperature of the components of economic activity influences,” says Diffenbaugh. It ‘clear that for poor countries, the news is bad.
