WASHINGTON – During a news conference by the National Oceanic and Atmospheric Administration and NASA, scientists revealed new information related to world climate. They said that the world climate is continued to climb and 2018 was the fourth warmest year on record. Also, they said that the temperature will continue to climb in the coming time. In the 20th century, the average global atmospheric temperature stood at 13.9 degrees Celsius. But in the year 2018, there was an increase of 0.79 degrees which makes it the fourth warmest year of all time.
With an increase in the temperature, the global rainfall has increased significantly which has contributed to situations of droughts as well as floods. Scientists further commented that this trend of temperature rising began in the mid-1970s and it had been increasing continually. Deke Arndt, who headed NOAA’s global monitoring branch in Asheville, N.C said.
Scientists further revealed that much of the Southern Hemisphere, 2018 recorded the average highs for the second year in a row. Parts of Europe, the Middle East, and the western Pacific in the Northern Hemisphere also recorded their hottest average temperatures. Also, in the Arctic region, the temperature continued rising faster than the overall global temperature rise.
Citing a connection between climate change and erratic rainfall patterns, Arndt said this condition has led to an increase in droughts as well as floods. Since a warmer atmosphere holds more water so it could cause both droughts by holding water for a long time. Also, when it releases water then it leads to flood situations in the entire world.
The adverse effect of these situations was witnessed in the nine eastern states of the US including Pennsylvania, Virginia, and Maryland. In the 20th century, the average rainfall was measured at 76 cm which rose by 11.9 cms in the year 2018 to reach a point, 87.9 cms. This trend of global warming is going to affect the globe adversely and all this is happening because of the increase in greenhouse gases.
