Global temperature rises a warning
Global temperatures for 2015 are expected to have risen by 1C for the first time since the industrial revolution started.
Temperatures around the world averaged 1.02C above the 1850-1900 period from January to September this year, the Meteorological Office said.
If the trend continues, it would make this year the first to pass the alarming threshold.
Forecasters said the rising temperatures were caused by an El Nino event, when Pacific waters become so warm they affect the world’s weather, as well as man-made warming.
While future years will not all be 1C above pre-industrial levels, because of natural climate variability, it will eventually become the norm.
