2017 surely will enter the top class of 'the warmest year in observation history'

NASA and NOAA (American Oceanic and Atmospheric Administration) From the global weather observation results that it is sure that 2017 is included in one of the years in which the average temperature in observation history was the highest.

2017 will rank among Earth's top 5 warmest years

NASA's Goddard Institute of Space and Astronautical Science (GISS) presents climate change prediction "GISTEMPAccording to (GISS Surface Temperature Analysis), it is almost certain that 2017 will be the second warmest year in observation history. Mr. Gavin Schmidt, a meteorologist led by Goddard Institute of Space and Astronautical Science, has tweeted the following images and revealed that the average temperature in 2017 is likely to be the second highest level after 2016 I will.

On the right side of the graph, the area where the average temperature data of 2017 will settle down is indicated by a yellow green line. Until now, the average temperature in 2015 was the second highest, but 2017 data is expected to exceed this by 98% establishment.


In addition, the data published by NOAA has revealed that 2017 was one of the warmest year. The following graph showing the temperature deviation of both the surface and the ocean after 1880 shows that the value in 2017 is the third highest in observation history.


As shown in both data, we know that the warmest year in the history of observation is 2016, but this year the sea surface temperature of some parts of the Pacific becomes higherEl Niño phenomenonWas occurring. Although the direct connection between the El Niño phenomenon and the earth's climate has not yet been elucidated, it is clear that there is a strong link between the two.

However, despite the fact that the El Niño phenomenon has not occurred in 2017, it is different from usual that the temperature is higher than usual.

According to the data of NOAA, 1985 was the last year when the average temperature fell below the previous year. In other words, I know that there is a strong trend that the average temperature will rise consistently over the past 32 years. And,Separation into Antarctic Larsen C shelf iceIt is said that it appears in phenomena such as, in the futureThe area where plague is caused by global warming will expandIt is also considered.
