We're Living Through Earth's Second-Hottest Year, Says US Agency

According to the body's balance sheet, the provisional data from January to October of this year reflect the highest temperatures since the beginning of systematic records, only slightly exceeded by those of 2016.

The government agency noted that the average global land and ocean surface temperature last month was 1.76 degrees above the 20th-century average of 57.1 degrees Fahrenheit.

Such events are typically associated with the hottest years, since they boost global ocean temperatures and add large amounts of heat to the atmosphere across the Pacific Ocean, the world's largest. The chance of this year being on the top-five-warmest years is basically guaranteed at 99%, according to NOAA's report.

October 2019 became once the 43rd straight October to be warmer than the 20th century moderate, and the 418th straight warmer-than-moderate month.

NOAA discovered that global land and ocean temperatures, so far, measured at 1.69 degrees Fahrenheit above the 20th-century average, 0.16 of a degree cooler than the record warmest year-to-date, set in 2016.

This follows the September warmer than normal, NOAA said tied 2015 as the warmest September in history. October 2019 turned out to be one of the 10 warmest Octobers since 2003 and one of the top five warmest months since 2015. For example, while NOAA leaves parts of the Artic out of its analysis, while NASA interpolates temperatures from the Artic, assuming the temperatures in the region are similar to their closest observation location.

In an illustration of the adaptations that can happen between monitoring agencies, the European Union's Copernicus Climate Commerce Provider ranked October as Earth's most popular such month, a minute bit edging out October of 2016. On the other hand, NOAA and NASA ranked October second on their lists.

According to the organisation, the temperatures in the month of October were recorded across different parts in the North and Western Pacific Ocean, northeastern Canada alongside various parts of the South Atlantic Ocean, Europe, Indian Ocean, the Middle East, South America, and Africa. "Only a small area in the western contiguous USA had record cold October temperatures", NOAA added.

The results show a clear, sharp spike that experts have shown can be explained through rising amounts of greenhouse gases - such as carbon dioxide, methane, and nitrous oxide - in the atmosphere.

Human actions, specifically burning fossil fuels reminiscent of coal and oil for power, are the principle contributors of greenhouse gases. Curiously, regardless of the absence of a declared El Niño within the tropical Pacific, global common sea floor temperatures ranked second-warmest on file for the month, working lower than a tenth of a level behind the file 12 months of 2016, when there was an intense El Niño occasion.
