Carbon dioxide (CO2) is the chief greenhouse gas that results from human activities and causes global warming and climate change. To see whether enough is being done at the moment to solve these global problems, there is no single indicator as complete and current as the monthly updates for atmospheric CO2 from the concentrations of CO2 in the atmosphere are increasing at an accelerating rate (http://www.co2now.org/Current-CO2/CO2-Trend/acceleration-of-atmospheric-co2.html) from decade to decade. accelerating from decade to decade. The latest atmospheric CO2 data is consistent with a continuation of this long-standing trend. What level is safe? The upper safety limit for atmospheric CO2 is 350 parts per million (ppm). Atmospheric CO2 levels have stayed higher than 350 ppm since early 1988. Current CO2 - CO2 Now Tue, 26 Aug 2008 02:44:15 +0100 http://co2now.org/Current-CO2/CO2-Now/annual-co2.html In 2009, the average concentration for atmospheric CO2 (Mauna Loa Observatory) was 387.35 parts per million (ppm). In 2008, it was 385.57 ppm. Since the 1958 start of precise CO2 measurements in the atmosphere, the annual mean concentration of CO2 has only increased from one year to the next. There have been no decreases in annual CO2 levels since direct instrument measurements began. The following CO2 data (http://co2now.org/index.php?option=com_content task=view id=171 Itemid=1) provides a snapshot of the longest-running, high-precision instrument record for atmospheric CO2: Current CO2 - CO2 Now Mon, 12 Oct 2009 09:02:32 +0100 http://co2now.org/Current-CO2/CO2-Now/Current-Data-for-Atmospheric-CO2.html The world's most current data for atmospheric CO2 is from measurements at the Mauna Loa Observatory in Hawaii. These high-precision measurements were started by Dave Keeling (shown in the photo) in March 1958. Today, the monthly average concentration of CO2 in the atmosphere is published by the National Oceanic and Atmospheric Administration (NOAA) within a week after each month ends. The source data is organized into a table and republished here at CO2Now.org so more people can see the latest CO2 level and the important CO2 trend. The table includes the full Mauna Loa instrument record for atmospheric CO2.

This 2008 update of the global carbon budget and trends was published in Nature Geoscience. The 2008 Carbon Budget shows that carbon dioxide emissions from human activities rose ~2 per cent in 2008 to an all-time high of 1.3 tonnes of carbon per capita per year. GCP scientists say that rising emissions from fossil fuels last year were caused mainly by increased use of coal but there were minor decreases in emissions from oil and deforestation. The GCP also estimates that the growth in emissions from developing countries increased in part due to the production of manufactured goods consumed in developing countries. >>>> More about the Global Carbon Budget (http://co2now.org/index.php?option=com_content task=view id=190 Itemid=31) Current CO2 - CO2 Now Sun, 31 Jan 2010 19:37:00 +0100 http://co2now.org/Know-the-Changing-Climate/Climate-Science/climate-science-news-and-updates.html Earth more sensitive to CO2 than previously thought December 7, 2009 SCIENCE DAILY – In the long term, the Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience. Alan Haywood, a co-author on the study from the University of Leeds, said If we want to avoid dangerous climate change, this high sensitivity of the Earth to carbon dioxide should be taken into account when defining targets for the long-term stabilisation of atmospheric greenhouse-gas concentrations. >>>> Read the full article in Science Daily.

Starting on Earth Day 2009, at least one CO2 Speaker’s Corner video is being featured here on the home page of CO2Now.org. Speaker’s Corner videos are also posted to YouTube.com/user/co2speakerscorner (http://www.youtube.com/user/co2speakerscorner) and Vimeo.com/channels/co2 (http://vimeo.com/channels/co2), with an open invitation to post your own video in reply. The CO2 Speaker’s Corner is moderated by Michael McGee, creator of CO2Now.org.

The panels take the sun's energy and create the electricity that powers the web servers inside the AISO data center that is visible behind the panels. Energy is also stored in batteries so the electrical power is available 24 hours a day, 365 days a year. @ This Site - About CO2 Now Tue, 04 Aug 2009 23:16:05 +0100
