The National Aeronautics and Space Administration (NASA) said 2017 was the second hottest year since 1880 in terms of the Earth’s global surface temperature. However, despite the rapid warming trend, weather in the Northern and Southern Hemispheres largely differed.

Recently, “bomb cyclone” Grayson hit southeast US, delivering sleet, ice, and snow, which led to a sharp drop in the temperatures in the US East Coast, with a low of -30℃ in some regions.

Meanwhile, Australia was suffering from the heat. Sydney’s highest temperature on Jan. 7, 2018 soared to 47.3℃, the hottest in nearly 80 years.

The temperature gap between the North and the South was about 100℃.

The World Meteorological Organization (WMO) said that these extreme weather conditions resulted from global warming. Global warming can change the frequency, intensity, spatial range and duration of extreme weather events and may lead to unprecedented events.

In recent years, extreme weather events have brought many adverse effects to the ecological environment and human health. 

Scientists have predicted that extreme low-temperature weather conditions would be reduced, but extreme high-temperature weather events would increase by 5 to 10 times until the end of the 21st century.
