2015 set to be ‘hottest year on record’, says UN
The U.N. weather agency has said that 2015 will be the hottest year on record and 2016 could be even hotter.
Why?
Due to a combination of a strong El Nino and human-induced global warming.
The El Nino weather pattern, marked by warming sea-surface temperatures in the Pacific Ocean, also causes extremes such as scorching weather and flooding. Meteorologists expect El Nino to peak between October and January and to be one of the strongest on record.
Other notable observations made:
Global average surface temperatures in 2015 are likely to reach the symbolic and significant milestone of 1° Celsius above the pre-industrial era. A preliminary estimate based on data from January to October showed that the global average surface temperature for 2015 was around 0.73 °C above the 1961-1990 average of 14.0°C, and approximately 1°C above the pre-industrial 1880-1899 period.
The years 2011-2015 have also been the hottest five year period on record, with temperatures about 0.57 °C (1.01 degrees Fahrenheit) above the 1961-1990 reference period. Global ocean temperatures were unprecedented during the period, and several land areas — including the continental United States, Australia, Europe, South America and Russia — broke previous temperature records by large margins.
Next year may yet be even warmer, since levels of greenhouse gases in the atmosphere have risen to a new record every year for the past 30 years, and the El Niũo phenomenon is likely to continue into 2016
