Global Temperatures are Soaring
Global Temperatures 1880 - 2015 (NOAA)

Global Temperatures 1880 – 2015

  • The hottest year on record is 2015 (see the right-most red rectangle on the graph)
  • The second hottest year is 2014
  • Temperatures have increased by 0.67°C per century between 1880 and 2014.
  • This is shown on the graph, by the black line moving from bottom left to top right.  It is the Long Term Trend Line and is  rising by 0.67°C per century.

Note:

  • The average global temperature for each year is shown, on the graph, by a rectangle
  • The blue rectangles show temperatures below the average
  • The red rectangles show temperatures above the average
  • These “temperature anomalies” are the temperature differences from the average temperature.

 NOAA 2014 Global Analysis

The US National Climatic Data Centre (NOAA) “Global Analysis: Annual 2014” states:

  • 2014 was the warmest year across the world’s land and ocean surfaces since recordkeeping began in 1880.
  • The average temperature for 2014 was 0.69°C above the 20th century average of 13.9°C, beating the previous record warmth of 2010 and 2005 by 0.04°C.
  • 2014 becomes the 38th consecutive year, since 1977, that the yearly global temperature was above average. [1977 is the most recent blue bar on the above graph.]
  • Nine of the 10 warmest years, in the 135-year period of record, have occurred in the 14 years of this  century. The hottest year last century was 1998 and it is now the fourth warmest year on record.
  • In 2014 the globe reached record warmth despite an absence of El Niño conditions. This is important as El Niño conditions tend to increase global temperatures.
  • 2014 was the warmest year on record for many countries including: the United Kingdom, France, Switzerland, and Germany
  • For Australia, 2013 remains the warmest year on record, with 2014 becoming the third warmest in the 105 year record.

Australia’s hottest year remains 2013

“2013 will go down as the year that registered Australia’s hottest day, month, season, and … calendar year. … We’re not tinkering away at records – they’re being absolutely blitzed.”
(Sydney Morning Herald, Dec 2013)
(Bureau of Meteorology: Australia’s 2013 Climate Statement)

2015 was Australia’s fifth-warmest year on record, while national rainfall was slightly below average according to data collected and analysed by the Bureau of Meteorology.

The temperature increase is already damaging

We are already experiencing significant impacts of this warming:

  • Hotter weather with extended fire seasons
  • Droughts, bushfires and floods are more frequent and intense
  • The distribution of plants and animals is shifting towards the poles,
  • The planet is losing ice
  • The oceans are rising faster

It is not sustainable for us to have global temperature increasing like this.
