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.

Globally, July 2014 was the 4th warmest July since global temperature records began in 1880.  Eight of the warmest July's have occurred in the past ten years.  The coolest on record was July 1911. [NOAA Global Monthly Analysis]

Annually, 2013 tied 2003 as the 4th warmest year globally since 1880.  Nine of the ten warmest years in the past 134 years occurred since the Year 2000.  Only one year during the 20th Century--1998--was warmer than 2013.  [NOAA Global Analysis 2013]


"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."

~ Christine Lagarde, Managing Director
International Monetary Fund

More about global temperature is available in the State of the Climate reports (Global Analysis) at the NOAA-NCDC website. These reports present preliminary, global data that has been gathered from monitoring stations and leading institutions around the world. The reports include a Global Hazardssection that gives a global update on drought & wildfires, flooding, storms, severe winter weather, and ecosystems impacts. A Snow and Ice section reports on snow cover in the Northern Hemisphere and sea ice extent in the Northern and Southern Hemispheres.
