2018 fourth hottest year on record

NASA and the National Oceanic and Atmospheric Administration (NOAA) released data on the Earth’s global temperature last year. Information shows that 2018 was the fourth warmest year on record.

As indicated by NASA data, in 2018 the global land surface temperatureoin and oceanow was 0.83 degrees Celsius higher than between 1951 and 1980. In turn, NOAA data show that the temperature on Earth last year was 0.79 st. C. above the 20th century average. Since 1880, which is when measurement began to be conductedow, only three years have been warmer. This 2016, 2015 and 2017.

Since the 1980s. nineteenth century, the average global temperature rose by about 1 degree Celsius. This warming is largely due to increased emissions of carbon dioxide and other gasesoin greenhouse gases into the atmosphere and is caused by human activity.

But global warming does not mean that every place on the planet has experienced higher temperatures in the same range. According to NOAA, the average annual temperature in 2018 for Stanoin the United States was 14. warmest on record. But warming trends are strongest in the Arctic region, where last year there was a continued loss of sea ice. The region has been warming for twooch up to three times faster than the rest of the world. In addition, the loss of the Greenland and Antarctic ice sheets contributes to raising the level of morz and oceanow. Rising temperatures can roalso contribute to other extreme weather events.

– The effects of long-term global warming are already being felt in the form of coastal flooding, heat wavesoin, intense precipitationow and ecosystem changes,” said Gavin Schmidt of NASA.

NASA obtains temperature data from 6,300 weather stations located on land. In addition, the temperatures of morz and oceanow are made by ships sailing in the waters of almost the entire planet and research buoys. NASA also has research stations in Antarctica.

Computer algorithms helped analyze the data, whichore took into account the zrohe varied distribution of stations measuring temperatures around theoĊ‚ globe. They took into account the roThe so-called. urban heat islands, ktore can distort the analysis.

– The key news is that the planet is warming up. We know where it all comes from. Greenhouse gases are responsible for this, ktore introduced into the atmosphere over the past 100 years – admitted Schmidt. The trend is not new. 9 of the 10 warmest winters have occurred since 2005, and the last five years have been the hottest on record for measuring theow.

The findings of NASA and NOAA coincide with the conclusions of scientists of theow from the British Met Office and the World Meteorological Organization. These institutions row also recognized 2018 with the fourth warmest year on record. Significantly elevated temperatures zarowno landow, as well as the oceanow, noted in most of Europe, the Mediterranean basinoof land, the Middle East, New Zealand and Russia, as well as parts of the Atlantic and western Pacific oceans.

But not everywhere temperatures approached their recordsow. Central areas of America PoNorth, especiallyoCanada’s vast prairies, were cooler. However, the ogoln general, worldwide, zarowno land as well as seas were hotter than in previous years.
