Australia’s Institute of Public Affairs published an article in the science journal which claimed that the reason for global warming is natural and has nothing to do with humans. With some experiments, the two authors named Jennifer Morahsy and Breitbart, tried to prove that global warming is a natural phenomena. The emission of carbon dioxide and industrial warming has nothing to do with the warming up of Earth. However, the renowned scientists call the paper as junk science pointing out various flaws.
SO WHAT HAPPENED
Jennifer Morahasy, one of authors of the study claimed that they had undergone massive research to conclude that the rising global warming is completely natural and had nothing to do with actions of humans. The advanced computer models were used to find out that most of the global warming comes from natural forces.
John Abbot is the IPA’s lead author and he claimed for an academic affiliation to James Cook University. The university said that the academic affiliation had expired six months prior to submission of the research to the journal.
DETAILS OF WHAT WAS SAID
Proxy temperature records were used by the authors which are calculated by analyzing tree rings and sediments of the lake. Despite having hundreds of such temperature records, they selected only two without stating their reason for the choice. They put such records into various software from which a series of temperature reconstructions came as an output. The duo then based their claims on the results.
They said that results show that the world would have warmed up like this even if the industrial revolution or the emission of the green house gases hadn’t taken place. They claimed that despite doubling up the amount of carbon dioxide in atmosphere, the global warming would have reached 0.6C.
However, various scientists including Professor Steven Sherwood (University of New South Wales, deputy director at the climate change research centre), Dr. Gavin Schmidt (NASA Goddard Institute for the Space Studies, director), and Professor Piers Forster (University of Leeds, director of Priestley international centre for the climate) have pointed out various flaws in the paper and the methodology used.
Scientists believe that the study is baseless and has jumped to conclusions without proper research. The methodology used by the authors cannot work and scientists believe that there are several issues in the data. Only paleoclimate records have been used and there has been no scientific approach used. Thus, the claims made by the authors are baseless and pointless.
