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, CO2Now.org 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.

Some US media coverage likely has a role
in polarizing climate change beliefs
Most people rely on secondary sources for information, especially
the mass media; and some of these sources are affected by concerted campaigns
against policies to limit CO2 emissions, which promote beliefs about climate
change that are not well-supported by scientific evidence. U.S. media coverage
sometimes presents aspects of climate change that are uncontroversial among the
research community as being matters of serious scientific debate. Such factors
likely play a role in the increasing polarization of public beliefs about
climate change, along lines of political ideology, that has been observed in
the United States.
“Eelgrass beds and salt marshes effectively bury carbon for thousands of years,”
says Sierra Club BC’s science advisor, Colin Campbell, PhD. “This is probably
the most efficient carbon removal mechanism on Earth – and we should make good
use of it while we still have a chance to avoid the worst climate scenarios.”

This "Blue Carbon" exceeds the carbon fixed and stored by plants on land ("Green Carbon") each year. While perhaps lacking the conservation glamour of rainforests, it is a compelling fact that "the lon-term sequestration of carbon by 1 km2 of mangrove area is equivalent to that occurring in 50 km2 of tripical rainforest.

Unlike grandiose geo-engineering solutions, natural carbon sinks encourage a far more benign form of intervention, namely preservation, restoration, enhancement and expansion of existing Blue Carbon systems.

WASHINGTON — Warning that the risk of dangerous
climate change impacts is growing with every ton of greenhouse gases emitted
into the atmosphere, a National Research Council committee today reiterated the
pressing need for substantial action to limit the magnitude of climate change
and to prepare to adapt to its impacts. The nation's options for responding to
the risks posed by climate change are analyzed in a new report and
the final volume in America's Climate Choices, a series of studies requested by
Congress. The committee that authored the report included not only renowned
scientists and engineers but also economists, business leaders, an ex-governor,
a former congressman, and other policy experts.
"The goal of the America's Climate Choices
studies is to ensure that climate decisions are informed by the best possible
scientific knowledge, analysis, and advice, both now and in the future,"
said committee chair Albert Carnesale, chancellor emeritus and professor,
University of California, Los Angeles.
The new report reaffirms that the preponderance of
scientific evidence points to human activities -- especially the release of
carbon dioxide and other greenhouse gases into the atmosphere -- as the most
likely cause for most of the global warming that has occurred over the last
several decades. This trend cannot be explained by natural factors such as
internal climate variability or changes in incoming energy from the sun. The
report adds that the impacts of climate change on human and natural systems can
generally be expected to intensify with warming.

Why 450 ppm is not a safe target | Skeptical Science
A target of 450 parts per million (ppm) CO2 in the atmosphere
is widely regarded as synonymous with keeping mean global temperature by 2100
to no more than 2°C above pre-industrial levels. This is very misleading
and dangerous. For reasons set out below, achievement of that target,
probably by 2030, is likely to result in mean global temperatures dangerously
in excess of the predicted 2°C.

presents the 2011 RSA President’s Lecture. The dangers facing the earth’s ecosystems are well known and the subject
of great concern at all levels. Climate change is high on the list. But argues Sir David Attenborough, there is an underlying
and associated cause – population growth.
U.N. Forecasts 10.1 Billion People by Century’s End | NY Times
The new report comes just ahead of a demographic milestone, with the
world population expected to pass 7 billion in late October, only a dozen years
after it surpassed 6 billion. Demographers called the new projections a
reminder that a problem that helped define global politics in the 20th century,
the population explosion, is far from solved in the 21st. “Every billion more people makes life more
difficult for everybody — it’s as simple as that,” said John Bongaarts, a
demographer at the Population Council, a research group in New York. “Is it the
end of the world? No. Can we feed 10 billion people? Probably. But we obviously
would be better off with a smaller population.”Read UN Forecasts 10.1 Billion People by Century’s End

said, had specifically failed to meet the new challenge of climate change.

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.”

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.”

Atmospheric CO2 | Lowest level in 2.1 million years
Signatories to the UN Framework Convention on Climate Change (UNFCCC)
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.”
Atmospheric CO2 | Pre-Industrial Revolution
Atmospheric CO2 was stable at about 280 ppm for almost 10,000 years until 1750.
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.
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.”

Atmospheric CO2 | Projection for Year 2100
This scientific projection, based on an analysis on March 4, 2011, 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 | May 1, 2011
More than 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.)
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.
