2015-hottest-year-on-record

US researchers estimate that the average surface temperature of the planet has risen by 0.13 degrees Celsius compared to 2014, making 2015 the hottest year since record started in 1880.

Specialists at NASA and the National Oceanic and Atmospheric Administration independently of each other have reached the same conclusions. Moreover, 2015 is the 15th consecutive warmest year and the first with an increase in temperature, which exceeds rise in temperature from the previous year. This disturbing trend shows that the average temperature began to rise progressively and faster. The average temperature has risen by 1 degree Celsius since the late 19th century until now as the main reason scientists indicate high levels of pollution from human activity over the last 35 years.

Their claim is illustrated by the video, which the agency published. It depicts the average annual temperature and its increase from 1880 to 2015. There are moments of slight cooling, but form the 80s the temperature began to rise progressively. The base is the average temperature in the period 1951 – 1980 – the yellow and orange colors indicate higher than base temperature, and the blue color – lower.

“Climate change is a major challenge to our generation and the work NASA has done on this important issue has implications for everyone on Earth. This information emphasizes the importance of NASA’s program for Earth observation and the data must be taken into account by everyone – now is the time to act”

Charles Bolden director of NASA
