A new study that was published in the journal Science shows how increases in temperatures will affect our landscapes in the next 150 years, based on an analysis of the significant changes to Earth’s vegetation after the last ice age. The paper involved a team of 42 authors from all over the world and was led by the University of Arizona.
Observations of the new study
According to Janelle Stevenson from the Australia National University, the regions of our planet that experienced the biggest temperatures increases over the interval that was analyzed had seen the most significant changes in vegetation. The Australia National University is one of those involved in the international research team that has concluded that two-thirds of the vegetation on our planet went through some major changes from 21,000 years ago until the pre-industrial era, when we know that the temperatures on Earth warmed by four to seven Celsius degrees.
Using past results to reach a terrifying conclusion
Simon Haberle, who is one of the researchers at the Australia National University, mentioned that the team took into consideration results from changes that happened in the past to vegetation at 594 different sites from each continent, except Antarctica. They used this data in order to understand how drastically can the ecosystems change worldwide in the future. What allowed the researchers to find out how exactly the ecosystems might be transformed under several greenhouse gas emissions models was the connection between temperature changes and the alterations in vegetation.
According to Professor Haberle from the ANU Department of Archaeology and Natural History, the scientists have already noticed “warning signs of big changes in vegetation” throughout Australia because of the climate change. The new study shows again just how important it is for us to “move rapidly towards an emission-free global economy”, as Stevenson, a co-author of the paper, has mentioned.
Laura grew up in a small town in northern Quebec. She studied chemistry in college, graduated, and married her husband one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children.
