CO2.Earth is live!!
November 13, 2013
CO2.Earth is now live. I am proud that it is one of the very first websites on the internet with a .earth domain. The first .earth site to launch—democracy.earth—happened last week. This week, CO2.Earth is the site that's rolling out, just before .earth domains open for public registration on December 19, 2015.
Also, just in time for the international climate summit in Paris, CO2.Earth takes over global redistribution of CO2 data from CO2Now.org.
CO2.Earth is here to track the atmospheric CO2 trend along with you. Any time you want an update for earth's planetary vital signs, CO2.Earth points to the latest numbers.

Global Warming Update
This global temperature chart is updated at Columbia University by Dr. Makiko Sato.
Data is based on GISTEMP analysis (mostly NOAA data sources) as described by Hansen, Ruedy, Sato & Lo (2010).
The 1880-1920 average is used as best available base for pre-industrial global average temperatures.
See "A better graph" by Hansen and Sato (2016) for background info.

NOAA/NCDC: The combined average temperature over global land and ocean surfaces for November 2016 was the fifth highest for November in the 137-year period of record, at 0.73°C (1.31°F) above the 20th century average of 12.9°C (55.2°F). This value is 0.23°C (0.41°F) cooler than the record warmth of 2015 but 0.05°C (0.09°F) higher than the average November value for the 21st century to-date (2001–2016). [NOAA global analysis accessed December 19, 2016].
"The science is sobering—the global temperature in 2012 was among the hottest since records began in 1880. Make no mistake: without concerted action, the very future of our planet is in peril."

NOAA's global analysis for 2015 lists 2015 as the warmest year on record since 1880 at 0.90°C above the 20th Century average. The year 2014 is the second warmest at 0.74°C above the average. The year 2013 was the fourth warmest at 0.66°C above the average. [NOAA global analysis for 2015 accessed January 20, 2016].
"Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much."
~ NASA Goddard Institute for Space Studies [NASA post of January 20, 2016]
Before the end of 2015, scientists projected that average global temperature increase for 2015 will exceed 1°C above pre-industrial levels. The years 1850-1990 are used as the pre-industrial baseline by the MET Office and Climate Research Unit at the University of East Anglia in the UK. The MET Office released this statement in November 2015:
"This year marks an important first but that doesn't necessarily mean every year from now on will be a degree or more above pre-industrial levels, as natural variability will still play a role in determining the temperature in any given year. As the world continues to warm in the coming decades, however, we will see more and more years passing the 1 degree marker - eventually it will become the norm."
