Climate change: Scientists warn that damage to biodiversity could be "dramatic"
Researchers from the University of Arizona (USA) presented this week in the journal "Science" a new study related to climate change, and the results seem to worry the world's scientific community.
The experts assure that the increase in the temperatures of the Earth could cause a hecatomb similar to that happened in the ice age. This would bring about a "dramatic" damage to the biodiversity that we know today.
"We are talking about 100 or 150 years, unless the current emissions of greenhouse gases that the planet experiences are reduced. Otherwise, an effect similar to that recorded when the ice age came to an end and the vegetation of the Earth changed drastically, "explain the scientists at work.
Another of the conclusions of the study, which focuses on the prehistoric changes in vegetation and how they give a reading of the future of ecosystems, also points out that the increase in temperature has a great negative impact on any life on the planet.
Connor Nolan, member of the Department of Geosciences of the North American University, explains that the analysis presented has an antecedent based on some 584 reports of examinations made in all the continents, with the exception of Antarctica.
"The regions of the world that had the highest temperature increases since the ice age, also had the greatest changes in vegetation. That is our approach, "adds the specialist.
Nolan says that the relationship between changes in temperature and the way in which the vegetation of the analyzed regions has changed allows them to have a clearer reading of the changes that could occur due to the influence of greenhouse gases.
Establishing this relationship between the change in temperature and the degree of vegetation change allowed researchers to determine how ecosystems could change under various models of greenhouse gas emissions.
