CO2 Now


What the world needs to watch

Global warming is mainly the result of CO2 levels rising in the Earth’s atmosphere. Both atmospheric CO2 and climate change are accelerating. Climate scientists say we have years, not decades, to stabilize CO2 and other greenhouse gases.

To help the world succeed, makes it easy to see the most current CO2 level and what it means. So, use this site and keep an eye on CO2.  Invite others to do the same. Then we can do more to send CO2 in the right direction.

Watch CO2 now and know the score on global warming, practically in real time.

CO2 Emissions Target

Global energy balance  & the end of global warming

“Stabilizing climate requires, to first order, that we restore Earth’s energy balance.
If the planet once again radiates as much energy to space as it absorbs from the sun,
there no longer will be a drive causing the planet to get warmer.”

Atmospheric CO2  |  Average Annual Rise  |  November 2001 - 2010

November Data Only   The rate of increase for the latest decade is higher than any decade since the start of the atmospheric CO2 instrument record in March 1958.   For comparison with annual average data, the 2001-2010 rate of increase is 2.01 ppm per year.

Ocean Acidification:  Average pH of Surface Oceans  |  2005

Average pH of surface oceans has declined about 0.1 units since before the industrial revolution.  This is an increase of about 30% in the concentration of hydrogen ions which is a considerable acidification of the oceans. 

“…world leaders should take account of the impact of CO2 on ocean chemistry,
as well as on climate change…we recommend that all possible approaches
be considered to prevent CO2 reaching the atmosphere.”

Average Global Surface Temperature  |  November 2010

November 2010 is the second warmest November on record (since 1880).  November 2004 is the warmest on record.  

Preliminary data reported December 28, 2010 by NOAA-NCDC. 

 172 ppm

Atmospheric CO2  |  Lowest level in 2.1 million years

 194 countries

Target of Most National Governments

Signatories to the UN Framework Convention on Climate Change

The United Nation's ultimate climate objective “is to stabilize greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous human interference with the climate system.” 

 280 ppm

Atmospheric CO2  |  Pre-Industrial Revolution

Atmospheric CO2 was stable at about 280 ppm for almost 10,000 years until 1750.

 300 ppm

Atmospheric CO2  |  Highest level in at least 2.1 million years (pre-industrial)

Circa 1912, atmospheric CO2 levels breached the 300 ppm threshold for the first time in at least 2.1 million years.

 350 ppm

Atmospheric CO2 Target for Humanity

Atmospheric CO2  |  Upper Safety Limit

“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm, but likely less than that… If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.”

 385.99 ppm

Atmospheric CO2  |  Projection for Year 2100

This scientific projection, reaffirmed December 14, 2010, accounts for the voluntary emissions reductions pledges of parties to the UNFCCC since the Copenhagen climate talks.  The projected CO2 level represents a global temperature increase of about 4 °C.  


World Population | December 1, 2010

Almost 6.9 billion people are living on planet Earth. If humanity is to achieve a stabilization of atmospheric CO2 at safe levels, this is roughly the number of people who will need to be aligned with net CO2 emissions that approach zero. (See “0 tonnes” in The Climate Sheet.)

30.8 billion

Humanity's Global CO2 Emissions  |  2009

2009 global CO2 emissions were the second highest in human history.   Global fossil fuel emissions – more than 88% of all carbon emissions – are projected to increase by more than 3% in 2010.   In the past decade, 47% of CO2 emissions accumulated in the atmosphere, 27% were absorbed by land and 26% were absorbed by the ocean.  The 2009 data was published November 21, 2010

2010 WRAP UP

Climate Progress  |  Stunning year in climate science shows civilization on the precipice

For those interested in the real climate science story of the past year, let’s review a couple dozen studies of the most important findings


NYT Blog  |  2010 on Pace to Be Warmest on Record, NASA Says 

An analysis of average global temperatures through November by NASA’s Goddard Institute for Space Studies shows 2010 on pace to become the warmest year since the collection of temperature data began 130 years ago. NASA previously ranked 2005 as its warmest year ever.


NY Times  |  A scientist, his work and a climate reckoning

Perhaps the biggest reason the world learned of the risk of global warming was the unusual personality of a single American scientist….Charles David Keeling….But the essence of his scientific legacy was his passion for doing things in a meticulous way. It explains why, even as challengers try to pick apart every other aspect of climate science, his half-century record of carbon dioxide measurements stands unchallenged.

NY Times  |  Your piece of the Keeling Curve

“To me, it is kind of sobering to think that every pound of carbon that is emitted because I do something — drive a car or take an airplane or turn on a light — is going to influence the climate for a thousand years,” Dr. Solomon told me. “I actually take the bus more often now. That’s a personal choice.”

NY Times  |  Does the Keeling Curve Still Need a Keeling?

Climate science is under intensive scrutiny, with contrarians questioning virtually every aspect of the research. Even though [NOAA] and Scripps take their samples from many of the same places, including Mauna Loa, the vital work of calibrating the measurements is performed in separate laboratories, and that means the programs are genuinely independent of each other. So any time the measurement record comes under attack, an alternate version is readily at hand.

All major economies agree to cut emissions and establish a fund to help nations most vulnerable to climate change

LA Times  |  UN climate pacts contain small steps, no broad accord
Delegates agree to measure greenhouse gases and help vulnerable countries gird for worsening sea levels, droughts and hurricanes. The role of China and other developing economies remains a point of contention.

IPS News  |  Cancún Summit Gives Fossil Fuels a Free Pass 

The main cause of climate change is the burning of fossil fuels, so why are billions of dollars being invested to find and produce more oil, coal and natural gas? That is the question posed by Canadian indigenous representatives at the alternative civil society meet, Klimaforum, held parallel to the United Nations-sponsored climate summit under way in the Mexican resort city of Cancún.

Grattan Institue |  Markets to reduce pollution: Cheaper than expected

Technology innovation is the key to reducing carbon emissions cheaply. Grattan Institute investigated the experience of six pollution pricing schemes in Australia and overseas. In each case, costs to reduce pollution, and actual prices, were much lower than governments and their experts expected. 

Climate Spectator  |  Let the markets lead the way

Climate Spectator  |  Mind the free market trap

We all know the argument: Governments are inherently ineffective at guiding markets and will always screw it up when they try to. Markets, the argument goes, are inherently more efficient at picking technologies and responding to constraints, so should be left to do their thing.    


Climate Spectator  |  Investors say it’s time to act

It seems the world’s leading investors are sick of not being listened to on the critical issue of climate change, and financing the transition to low-carbon technologies. And they’ve decided to do something about it.

''If people's CO2 emissions continue as they have, the future of the reef is very grim. I would suggest that coral reefs will be highly altered and perturbed ecosystems by 2050 if we do not make a massive effort to curb our emissions. The findings back up much of the previous research that finds ocean acidification will have serious impacts on reefs.''

Climate Progress |  Sea levels may rise 3 times faster than IPCC estimated

“Since 1990, sea level has been rising at 3.4 millimetres per year, twice as fast as on average over the 20th century. Even if that rate just remained steady, this would already lead to 34 centimetres rise in the 21st century,” Dr Rahmstorf said. “But the data show us clearly – the warmer it gets, the faster the sea level rises. If we want to prevent a galloping sea level rise, we should stop global warming as soon as possible,” he said.
