Earth's temperature is constantly increasing

Use updated data on temperatures taken from thousands of terrestrial weather observatories and a lot of sea and commercial buoys, scientists at the US National Oceanic and Atmospheric Administration (National Oceanic and Atmospheric Administration-NOAA) said no signs of disruption have been found in recent growth rates. Not only that, this speed is also slightly increased compared to the second half of the 20th century. The study was published in the Science journal.

Earth temperature continues to increase

Specifically, the research results show that, in the past 15 years (the period from 2000-2014), the average temperature increased by 0.116 degrees Celsius per decade. This rate has not decreased, but it is actually a little higher than the average increase of 0.113 degrees Celsius per decade during the second half of the 20th century (1950-1999) - a period of marked capture. The head increases due to human activities. In addition, the new data also said that the increase in temperature has reached new records and 2014 is considered the hottest year in modern history.

Scientists warn that the use is making greenhouse gas emissions in the atmosphere increase faster. This directly raises the temperature, causing melting of the ice sector as well as increasing sea level and other serious consequences.

Reportedly, before this report, scientists once thought that temperature in the 21st century was almost unchanged.

According to a report published two years ago by the Intergovernmental Panel on Climate Change IPCC , the temperature increase in the period of 1998-2012 was only about 0.05 degrees Celsius per decade, compared with the average increase in the period. paragraph 1951-2012 is 0.12 degrees C.

Currently, Dr Karl, director of NOAA's National Climatic Data Center, thinks these numbers are no longer valid. Some experts also agree with NOAA's report because it believes that the data used in NOAA 's new report is more reliable and better than the data that IPCC uses.

However, there are some conflicting opinions from other experts. Professor Piers Forster at Leeds University points out that IPCC reports are based on a lot of data sets. He said that other databases, though calibrated to increase accuracy, would still show a downward trend in the rise in global temperatures since 1998.

From the point of view, we have to understand more about the changes of climate in each period, he said that this will not be the final study on this complex issue.
