Global warming: A population equivalent to that of Germany - 83 million people - could lose his life this century due to the increase in temperature caused by its gas emissions greenhouse, according new research.
The research carried out by Earth Institute of Columbia University, presents a new measure to help companies and governments to assess the damage caused by climate change. The calculation of its “mortality cost carbonCould give polluters new reasons for "liquidation", dramatically increasing the emission costs.
"Based on decisions made by individuals, businesses or governments, this measurement tells you how many lives will be lost or saved. In other words, it quantifies the impact of the mortality of these decisions "said Daniel Bressler of Columbia University, whose research was published, on the 29th of July, in the magazine Nature Communications.
Adapting models developed by William Nordhaus, a Yale economist and Nobel laureate, Bressler calculated the number of immediate heat deaths caused by current levels of global warming. His calculations do not include the number of people who may die from rising sea levels, superstorms, crop failures or diseases affected by global warming. This means that estimated deaths - where reach the number of people killed in World War II - could still be one "Huge devaluation", noted Bressler.
Every 4.434 tons of carbon released in 2020 in the Earth's atmosphere, will kill one person this century, according to expert estimates, which predict that the planet's temperature will rise by 4,1 degrees Celsius by 2100.
So far, the planet's temperature has risen by about 1,1 degrees Celsius, compared to pre-industrial years. The amount of pollution caused during the lifetime of three average U.S. residents is estimated to contribute to the death of another person. Bressler emphasized that Higher mortality rates are expected in the warmest and poorest regions of the world - in Africa, the Middle East and South Asia.
The new measure could have a significant impact on how economies calculate the so-called "social cost" of coal, as well as help governments determine policy by calculating future losses.
However, the scale revealed by Bressler's research suggests that the social cost of coal should be significantly higher, about US $ 258 per tonne, if the world's economies want to reduce the deaths caused by global warming.
Higher costs for carbon pollution could immediately lead to bigger emission cuts, which in turn could to save lives. Coverage of the average global temperature rise of 2,4 degrees Celsius by the end of the century, compared to the moderate emission reductions that will warm the planet by 3,4 degrees Celsius, could save 74 million people from death due to heat.
Finally, Bressler emphasized the following: "Governments need to adopt large-scale policies, such as coal pricing, ceilings, trade and investment in low-carbon technologies, and energy storage."
