A newly published study suggests that there would be greater greenhouse gas emissions because of high economic growth as was forecast previously. Owing to this, the scientists require recalibrating projections related to “worst case” climate change scenario. The new study has been conducted by taking greater global economic growth into account. The scientists conducted the study suggest that earth’s climate change forecast is based on the greenhouse gas emission, which in turn largely dependent on how the global economy behaves. They further suggest that if countries get richer, the more money will they consume, which naturally increases the greenhouse gas emissions. In this study, scientists use four scenarios called representative concentration pathways (RCPs) to predict the future of the planet.
During the study, they define the worst case scenario as RCP 8.5 in which assumption is made that there would be rapid and unrestricted economic growth with the unchecked burning of fossil fuels. And there would not be any action to limit the warming. However, there is one-in-three chance that emission would exceed estimated in the RCP 8.5 scenario, the scientists at the University of Illinois suggest. One of the climate researcher Peter Christensen claimed that due to higher than assumed economic growth rates, there would be more than 35 percent probability that by the year 2100 emissions concentrations will exceed those given by RCP8.5.
Climate change is certainly a matter of great concern. The emission of greenhouse gases is contributing significantly to this and disrupting the ecological balance of the planet. The melting glaciers, the rising sea levels, extreme weather conditions, suffocating oceans, etc are some of the visible impacts of global warming. All these impacts collective disrupting the biodiversity of the planet. Some of the species are on the brink of extinction due to these effects. The climate researchers are conducting research works and studies to read the impact and to find ways on how to slow down these rising temperatures.
In these efforts, the global community has drafted the Paris climate agreement which commits that the countries should prevent global warming to no more than 2C above pre-industrial temperatures by the end of the century. However, some of the research works have predicted that even if this target is achieved then also global temperatures could still rise by more than 3C, and possibly by over 4C. These rising temperatures would have a devastating effect on the planet. These may cause sea level rise to as much as 1.5 meters which would put cities like Amsterdam and New York under water and cause widespread famine.
So, there is much to be done to avoid such situations and to save our planet. The global community should think of this beautiful planet and work collectively to limit global temperature rise. Further, they should move to green technology so as to put a check on rising temperatures.
