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.

P.S. Please note that some articles and the set up of CO2 web widgets are still being completed.

June Global Temperature Change*
May Rankings: 1880 - 2019 Temperature Reocrd
Comparisons with 20th Century Global Average Surface Temperature
(Temperatures are not compared here with a pre-industrial baseline)
July 23, 2019
Averaged as a whole, the June 2019 global land and ocean temperature departure from average was the highest for June since global records began in 1880 at +0.95°C (+1.71°F). This value bested the previous record set in 2016 by 0.02°C (0.04°F). Nine of the 10 warmest Junes have occurred since 2010. June 1998 is the only value from the previous century among the 10 warmest Junes on record, and it is currently ranked as the eighth warmest June on record. Junes 2015, 2016, and 2019 are the only Junes that have a global land and ocean temperature departure from average above +0.90°C (+1.62°F). June 2019 also marks the 43rd consecutive June and the 414th consecutive month with temperatures, at least nominally, above the 20th century average. [NOAA/NCEI global analysis accessed July 23, 2019]
The month of June was characterized by warmer-than-average temperatures across much of the world. The most notable warm June 2019 temperature departures from average were observed across central and eastern Europe, northern Russia, northeastern Canada, and southern parts of South America, where temperatures were 2.0°C (3.6°F) above the 1981–2010 average or higher. Record warm temperature departures from average during June 2019 were present across parts of central and eastern Europe, Asia, Africa, South America, the north Indian Ocean, and across parts of the Pacific and Atlantic oceans.
Meanwhile, the most notable cooler-than-average temperature departures from average were limited to parts of western Asia and Antarctica, where temperatures were at least 1.0°C (1.8°F) below the 1981–2010 average or cooler. According to the June 2019 percentiles map, cooler-than-average conditions were limited to parts of western Asia, Indonesia, across small areas in the Atlantic and North Pacific oceans, as well as the south-central contiguous United States. No land or ocean areas had record cold June temperatures. [NOAA/NCEI global analysis accessed July 23, 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."
