The results of the study performed by the Boston University researchers published in the latest issue of Climate Change Letters journal indicates the imminent impacts of increase in the worldwide average temperature level and on the summer season temperature level in the U.S and other parts of the world.
Presently, world over efforts are being made to cut down the level of carbon discharges and heat-trapping gases to confine the level of human accelerated increase in global average temperature level to 2°C in comparison with the pre-industrial period though it has crossed the three-fifth level already.
According to Bruce Anderson, principal author of the study and associate professor of geography and environment at the University, the study wanted to establish the impact of such increase in temperature on the incidence of global average temperature increase in various parts of the world and wanted to find out if stopping the level of increase in the global-mean temperature level from reaching the verge level will stop the occurrence of increase in the temperature values as a regular phenomena in these regions.
The research suggests that if the 2°C increase occurs 70 to 80% of global land surface will suffer summertime temperatures at least for six months in a year thus making it a regular temperature feature for most of the land surface. Anderson points out that places such as Amazon, Indonesia, southeastern and Central portions of Asia and Africa are in the verge of reaching the limit with the current level of carbon discharges. He further explained that the global average temperature level will witness an increase of 0.6°C in the next 10 years even if zero level of heat-trapping gases, methane and carbon dioxide are contributed to the atmosphere.
According to him the impacts in the USA will be harsher on the western third of the country which are on the verge of reaching the level. He explained that the passing of 2°C threshold level will increase the level of summertime temperature in the region when compared to today and it will follow the footsteps of Amazon, Asia and Africa regions to have summertime temperature increases as a standard.
