translated from Spanish: The country that has most benefited with climate change (and hardest)

Climate change exacerbated economic inequality at the level worldwide, according to a new study.
One 25% higher the gap in the gross domestic product (GDP) of the richest countries and the poorest is now than it would have been because of global warming.
And that’s because there are countries to which climate change is benefiting.
The more is Norway, according to the research of two academics from Stanford University, in the United States.
Changes in temperature caused by the emission of greenhouse gases has especially enriched countries in climates colder, such as Norway, Canada and Sweden.
Protests against climate change outside the Norwegian Parliament in Oslo, the capital of the country were recently held. And at the same time it has depressed economic growth in Nations such as India, Nigeria and Brazil’s hottest climates.
“Our results show that the majority of the poorest countries of the Earth are considerably poorer what would be without global warming,” said climate expert Noah Diffenbaugh, lead author of the study published in the Journal of the Academy of Sciences of United States, Proceedings of the National Academy of Sciences, or PNAS.

Temperature and GDP
While economic inequality between countries has fallen in recent decades, the study shows that the gap between the rich and poor Nations had decreased more quickly without global warming.
The study is based on one preliminary investigation of another of the authors of the study, Marshall Burke, Professor of Earth systems at Stanford.
Burke and his colleagues analyzed 50 years of annual temperatures and 165 countries GDP data in a previous job. And they showed that economic growth in warmer than average years accelerated in countries with colder climates, such as Norway, and became slower in countries with warmer climates.

The new study published this week indicates that from 1961 to 2010, global warming decreased in average wealth per capita in poor countries between 17% and 30%.
“The historical data show clearly that when the temperature is not too cold or too hot, crops are more productive and people are healthier and more productive,” said Burke.
“This means that in cold countries, it helps a little bit of heat. “But the opposite is true in countries that already have high temperatures”.
Tropical countries
“In the case of the majority of countries, know with enough certainty whether global warming helped or harmed economic growth”, said Burke.
Tropical countries, in particular, tend to have temperatures that are far from ideal for economic growth.
“There is no doubt that climate change has damaged them.”

It is less clear what has impacted global warming latitudes Nations averages, as the United States, China and Japan.
For these and other Nations more temperate climates, the study indicates one economic impact less than 10% of GDP.
“Some of the major economies have ideal temperatures for the production. But the increase of global warming in the future will push them further and further away from the optimum,”said Burke.
“Tremendous loss”
On average, the biggest emitters of greenhouse gases recorded an increase in per capita GDP of 10% with respect to which would have taken place without the global warming.
But in countries that emit fewer gases responsible for climate change, per capita GDP fell an average of 2%.
“This decline is comparable to the one registered in the United States during the great depression. It is a tremendous loss in comparison to what these countries could have registered,”said Burke.
The study emphasizes the importance of that poor nations have access to renewable energy sources to be able to continue growing without aggravating global warming. Global impact
Apart from losers and winners in the short term, if the warming continues its current course nobody will benefit, according to the predictions of the Intergovernmental Panel on climate change, IPCC, for its acronym in English.
The domino effect that can turn Earth into a greenhouse irreversibly
CO2 emissions must fall by 45% by 2030 to avoid effects more catatroficos of climate change, according to the IPCC. The concentrations of CO2 in the atmosphere have increased steadily in recent decades. The increase in the level of the sea, the melting of glaciers, mass migration from the most affected countries to Europe and the United States, the intensification of droughts and hurricanes and the loss of crops will have an impact around the world.
In his crucial report by October 2018, the IPCC said global CO2 emissions would fall by 45% by 2030 to that global warming does not exceed 1, 5grados at the global level in relation to preindustrial levels.
