NASA reviews global temperature measurements and validates upward trend

NASA is among the scientific institutions dedicated to monitoring the planet's temperatures - and turns and stirs up frightening surveys of how much they have risen in recent decades. More specifically, the measurements are conducted by the space agency's Goddard Institute for Space Studies, but the surveys brought "statistical uncertainties." However, the data has just been revised and, in addition to making the series extremely accurate and much more reliable, they have confirmed the upward trend in global temperatures.

Revision Required

The temperatures of the planet began to be recorded in 1880, that is, almost 140 years ago, and a few decades ago, NASA people, in partnership with NOAA - National Oceanic and Atmospheric Administration, US agency for related issues. With the weather, the oceans, the atmosphere, and the climate, annual measurements began.

This work is based on data collected by 6, 300 weather, research, watercraft and buoys across the earth, but the scientists responsible for the estimates knew there could be a slight margin of error in measurements - the so-called “statistical uncertainty”. But now, after the information has been revised, fluctuations have been reduced to just 0.05 ° C for the information collected over the past decades, and to 0.15 ° C for data obtained 140 years ago.

What's more, the study conducted now found that from 1880 to today, temperatures on the planet have risen by 1.1 ° C. In addition, analysis of the information has allowed scientists to conclude that the 10 warmest years since records began in the past 2 decades, with 2016 hitting the highest temperature in the last (almost) 140 years - followed by 2017, 2015 and 2018 years.

But in addition to this survey - conducted through thousands of devices around the world - NASA also collects data and monitors global temperatures through other means. One is the Aqua satellite, whose primary mission is to study the water cycle and is equipped with a device that measures atmospheric temperature and humidity, as well as the temperature of the planet and the surface of the oceans, and their readings coincide with result of the reviews.

In addition, NASA and NOAA are not the only scientific institutions eyeing thermometers, and the same trend of global warming has been presented time and time again. To make matters worse, predictions about the consequences of rising temperatures - including longer periods of drought, higher incidence of forest fires, melting of polar regions and so on. - are also confirming.
