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.

The January 2018 temperature across global land and ocean surfaces was 0.71°C (1.28°F) above the 20th century average of 12.0°C (53.6°F). January 2018 marks the 42nd consecutive January (since 1977) and the 397th consecutive month (since January 1985) with temperatures at least nominally above the 20th century average. This was the fifth highest temperature for January in the 1880–2018 record. The last four years (2015–2018) rank among the five highest Januarys on record. The global land and ocean temperature during January has increased at an average rate of +0.07°C (+0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1975. [NOAA/NCEI global analysis accessed February 18, 2019].
"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/NCEI annual global analysis for 2018:
The 2017 average global temperature across land and ocean surface areas was 0.84°C (1.51°F) above the 20th century average of 13.9°C (57.0°F), behind the record year 2016 (+0.94°C / +1.69°F) and 2015 (+0.90°C / +1.62°F; second warmest year on record) both influenced by a strong El Niño episode. The year 2017 is also the warmest year without an El Niño present in the tropical Pacific Ocean.
2017 also marks the 41st consecutive year (since 1977) with global land and ocean temperatures at least nominally above the 20th century average, with the six warmest years on record occurring since 2010. Since the start of the 21st century, the global temperature has been broken five times, three of those being set back to back (2014–2016). The yearly global land and ocean temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1980. From 1900 to 1980 a new temperature record was set on average every 13.5 years; however, since 1981 it has increased to every 3 years.
Overall, the global annual temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880 and at an average rate of 0.17°C (0.31°F) per decade since 1970."

"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."

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."
