Temperature
Global Temperatures are Soaring
- The black line shows the “long-term trend” of the “average global air temperatures” from 1880 to 2015 produced by the US National Oceanic and Atmospheric Administration (NOAA)
- The upward trend in temperature continues after 2015.
- Below, I describe how to get the most recent graph.
- Temperatures have increased by 0.67°C per century between 1880 and 2014.

More recent graphs: The same message
The graph above shows the period from 1880 to 2015. The more recent graphs carry the same message.
The Trump administration has removed much climate information from U.S. websites; however, you can find other temperature graphs in the NOAA global climate reports.
In most recent years are the hottest.
- In the above 1880 to 2015 graph, 2014 and 2015 were the hottest years
- Each “temperature anomaly” shows the temperature difference from the average temperature in degrees Fahrenheit.
- The average global temperature anomaly for each year is shown by a rectangle:
- The blue rectangles show temperatures below the average
- The red rectangles show temperatures above the average
- The hottest year on record was 2015. (See the right-most red rectangle on the graph.)
- The second hottest year was 2014.
Generate the latest Temperature Graph
- Go to the Global Time series page:

- Select Time-scale = “Annual”
- Tick “Display Trend”
- Select “trend per C

- Select Surface = “Land and Ocean”
- Click “Plot”
The temperature increases are 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 the global temperature increasing like this.
