Two top American scientific agencies NOAA and NASA in their separate releases have confirmed the trend of global warming is continuing. The releases were made on 22 January 2014.
Annual climate report of National Oceanic and Atmospheric Administration (NOAA) shows that above-average annual temperature was experienced in most of the planet in 2013. As per the release, 2003 was the fourth warmest year, since record keeping began in 1880. The temperature of 2013 tied with the temperature experienced by the world in 2003.
As per the report of the combined global land and ocean surface temperature was recorded 0.62 degrees Celsius (1.12 degrees Fahrenheit) above the 20th century, which is average 13.9 Celsius (57 degree Fahrenheit).
A second analysis by the NASA scientists came forward with a different result that says that the global temperature of the year 2013 tied with the temperature recorded in 2006 and 2009. It says that the recorded temperature is the seventh warmest year, which is in record.
Process of detecting the global temperature used by the two agencies is slightly different but they agree on the trend of calculation.
As per the data of past 134 years, global warming due to the building-up of the greenhouse gases has been attributed as the reason for the rise in temperature. It has been attributed by the climate scientists depending on the nature of carbon dioxide released in the atmosphere of the planet, which is released from the emissions caused from transport vehicles, industries and power. As per NASA, CO2 is at its highest level in the atmosphere in the 8 lakh year long atmosphere. It has recorded the rise of the gas to 400 parts per million in 2013 as compared from 285 parts per million in 1880.
