WMO highlights human action on climate change.
UN-WMO News Center, November 8, 2016.
The luster 2011-2015 has been the warmest recorded so far, during that same period greenhouse gas concentrations continued to rise and reached unprecedented levels. High temperatures have been accompanied by other indicators such as rising sea levels and decreasing sea ice extent. More than half of extreme weather events, such as droughts, heat waves and floods, were due in part to the impact of global warming caused by human activities. Cyclones and typhoons activity also increased.
Hot and wild, this is how the weather has behaved in the last five years, says a report by the World Meteorological Organization (WMO) that identifies an increasingly visible human footprint as a cause of climate change.

The study notes that the 2011-2015 luster has been the warmest recorded so far, and 2015 was the year with the highest temperatures.
Released today, the analysis also indicates that greenhouse gas concentrations continued to rise and reached unprecedented levels in the same period.
Higher temperatures have been accompanied by other indicators consistent with climate change, such as rising sea levels and decreasing Arctic sea ice, continental glaciers and snow cover in the northern hemisphere.
Another important finding is that more than half of extreme weather events, such as droughts, heat waves and floods, occurring between 2011 and 2015, were due in part to the impact of global warming caused by human activities.
The report mentions some of the most significant events of this type, including the East African drought between 2010 and 2012, which caused some 258,000 deaths. It also cites floods in South East Asia in 2011, leaving 800 dead and more than $ 40 billion in losses.
He also cited heat waves in India and Pakistan in 2015, Hurricane Sandy in the United States in 2012, with losses of more than 67 billion dollars, and typhoon Haiyan in the Philippines, which killed 7,800 people.
