Last 5 years were hottest on record: UN
The usual dishonesty. The real news is that temperatures have in fact plateaued, except for a minor blip in 2015 caused by the El Nino weather cycle. Here are the actual global mean temperature anomalies in degrees Celsius as given by GISS for the 5 years concerned:
2011 .61; 2012 .64; 2013 .66; 2014 .75; 2015 .87
You will see that the temperatures for the first three years in the series differed only in hundredths of a degree, essentially meaning no change. And the remaining two differed only in tenths of a degree. It's essentially a picture of stasis: no change worth talking about
Note also that the temperatures for 1998 (.63), 2002 (.63), 2003 (.62) and 2005 (.69) were very similar to the recent temperatures, again indicating no change
And the 2011, 2012 and 2013 temperatures were DOWN on the 2010 figure (.72). Handy that they took 2011 as their starting point, isn't it? Wouldn't want to upset a neat picture of rises, would we?
And isn't is wonderful what you find when you look at the actual numbers? You would guess none of what I have just pointed out from the alarmist guff below
The past five years were the hottest on record with mounting evidence that heat waves, floods and rising sea levels are stoked by man-made climate change, the United Nations weather agency says.
Some freak weather events would have happened naturally but the World Meteorological Organization (WMO) on Tuesday said greenhouse gas emissions had raised the risks of extreme events, sometimes by a factor of 10 or more.
"We just had the hottest five-year period on record, with 2015 claiming the title of hottest individual year. Even that record is likely to be beaten in 2016," WMO Secretary-General Petteri Taalas said in a statement.
Among the worst extremes, a 2011-12 drought and famine in the Horn of Africa killed more than 250,000 people and Typhoon Haiyan in the Philippines killed 7800 in 2013, the WMO said.
Superstorm Sandy caused $US67 billion ($A87 billion) of damage in 2012, mostly in the United States, it said in a report issued to a meeting of almost 200 nations in Morocco tasked with implementing a 2015 global agreement to combat climate change.
The last five-year period beat 2006-10 as the warmest such period since records began in the 19th century.
The heat was accompanied by a gradual rise in sea levels spurred by melting glaciers and ice sheets. The changes "confirmed the long-term warming trend caused by greenhouse gases", the WMO said of the report.
And the amount of carbon dioxide, the main greenhouse gas, reached 400 parts per million in the atmosphere for the first time in records in 2015, it said.
Last year was the first in which temperatures were one degrees Celsius above pre-industrial times, partly because of an El Nino weather event that warmed the Pacific.
The 2015 Paris Agreement set an overriding target of limiting warming to "well below" 2 degrees above pre-industrial times, ideally just 1.5 degrees.
But pledges so far to curb greenhouse gas emissions are too weak and put the globe on target for about 3 degrees, UN data shows.
