Migrations as a consequence of climate change have already begun, warned the US expert John Short in Colombia today, who assured that the world is not prepared for the effects of global warming. "The migration of people due to climate change has already started. In Bangladesh, for example, there are climate change refugees who have left their homes in rural places because they can no longer coexist with such an aggressive climate environment," said the specialist in an interview with Efe.
Short, a doctor from the British University of Bristol and an expert on urban problems, geography, environmental issues and globalization, said that changes in nature "will become (the) new normal for beings on the planet."
As part of his theory on climate change on which he spoke at the Icesi University, in the Colombian city of Cali (west), the researcher indicated that this "new normal" will bring exoduses to major cities, which are shown as survival option for those who live in the most remote areas.
"No city is prepared for an unforeseen migration such as that caused by climate change," said the expert, who pointed out that these new migrants "are groups with economic limitations", which complicates their adaptation to the urban environment.
The path that the American professor points out to face climate change is made up of adaptation and mitigation.
The first term refers to "how human beings can habituate the artificial environment, to the new normality," explained Short, who described mitigation as "acts to appease the effects of climate change."
As examples of mitigation, the expert mentioned alternative sources of energy such as wind, used by countries such as Spain and Denmark.
However, he indicated that "these options are being overshadowed by the current oil price situation, which has fallen considerably."
He also referred to "green roofs", as the vegetation planted on the facilities is known to reduce the waste that goes to the ozone layer.
As for adaptation, Short explained that it is a more complicated process, since the "new normal" is different in each part of the world and requires more resources.
"The problem is that we do not know exactly how the change will be in each part of the world," he said.
