This week, the National Oceanic and Atmospheric Administration have released data that reveals that this year is increasingly likely to be the planet’s second or third-warmest calendar year on record since modern temperature data collection in 1880. 

This is being considered as the long term effect of human-caused global warming. It is also notable, there was an absence of a strong El Niño in the tropical Pacific Ocean this year. These types of incidents are observed in the hottest years as they increase global ocean temperature and add large amounts of heat to the atmosphere across the Pacific Ocean, the world’s largest. 

On Monday, as per a newly released report, there is about an 85% chance that the year will be recorded as the second-warmest in NOAA’s data set, with a possibility that it slips No. 3. However, it is confirmed that 2019 will wind up being a top-five-warmest year for the globe. 

NOAA discovered that the average global land and ocean surface temperature for October was 1.76 degrees above the 20th-century average, just 0.11 of a degree shy of the record warm October set in 2015.

Since 2003, the 10 warmest Octobers have occurred and the top-five warmest such months have taken place since 2015. October 2019 was the 43rd straight October to be warmer than the 20th-century average and the 418th straight warmer-than-average month. 

This means that anyone younger than 38 has not lived through a cooler-than-average year from a global standpoint. So far this year, global land and ocean temperatures have come in at 1.69 degrees above the 20th-century average, just 0.16 of a degree cooler than the record warmest year-to-date, set in 2016, NOAA found.

Though NOAA’s opinion regarding 2019 may be slightly different from other agencies who track global temperatures, their overall idea is the same. For example, NASA interpolates temperatures across the data-sparse Arctic by assuming that the temperatures region-wide are similar to their closest observation location. On the other side, NOAA leaves parts of the Arctic out its data. 

The data of NOAA may be slightly underestimating global temperatures considering the fact that the Arctic is warming at more than twice the rate of the rest of the world. Scientists have clearly shown for several times, the increasing amount of greenhouse gases, such as carbon dioxide, in the atmosphere are responsible for global warming. Human activities like burning fossil fuels such as coal and oil for energy are the main sources of greenhouse gases.
