Mauna Loa Observatory, Hawaii (USA) Atmospheric CO2 was 391.06 parts per million (ppm) in March 2010, according to scientific data released April 8, 2010, by the National Oceanic and Atmospheric Administration (NOAA) in the United States. Atmospheric CO2 was 388.77 ppm one year earlier in March 2009. 
capacity of the land and oceans to absorb it. The absorption of CO2 by oceans slows the rate of increase in atmosphere levels and raises the acidity of the oceans. |
You may have noticed that Atmosphere Monthly is starting to change. Some things are scaled back. Some additions and improvements have been made. It will take a few months for the changes to be complete. Also, work has started on an upcoming Wish for Zero special edition. Look for an upcoming special edition to focus on what people like Bill Gates are saying about the need and ways to get global emissions dropping quickly toward zero. The coming Wish for Zero special edition is, in fact, inspired by Bill Gate's recent TED Talk called Innovating to Zero. You can hear him by watching the video that is embedded further down in this newsletter. Thank you for reading through the April edition of Atmosphere Monthly. |

Global Climate Update: Warmest March in 131 years
Data for this Global Climate Update comes from a number of leading scientific institutions around the world. The summary is based on a more a detailed State of the Climate Global Analysis by the National Oceanic and Atmospheric Administration (NOAA) in the United States. A link to the more detailed NOAA report is found below.
Global Temperature
In the past 131 years, global surface temperature measurements for March were the warmest warmest in March 2010. The global average includes land and ocean surface temperatures.

Sea Ice Extent
Arctic sea ice extent was the fifth lowest for March since satellite records began in 1979. It was 4.1 percent or 650,000 square kilometres below the 1979 - 2000 average. This was also the 17th consecutive March when Arctic sea ice extent was below average.
The maximum Arctic sea ice extent during March 2010 occurred on March 31st—the latest date for the maximum sea ice extent since records began in 1979. The previous record for latest date was set on March 29, 1999.
In the Southern Hemisphere, March 2010 sea ice extent was 6.9 percent below the 1979-2000 average. This was the 2nd consecutive March when Antarctic sea ice extent was below average. Since 1979, it was the eighth least sea ice extent in March.

How do we know the Earth's climate is warming?
Many lines of scientific evidence show the Earth's climate is changing. NOAA’s National Climate Data Center presents seven global climate change indicators.

Innovating to Zero Can we end poverty and AIDS without ending the climate crisis? Bill Gates of the Bill and Melinda Gates Foundation says ‘no.’ That’s why he’s now talking about what it will take to end global warming and related planetary problems like climate change.
“We put out a lot of carbon dioxide every year: over 26 billion tons....it’s an average of about 5 tons for
everyone on the planet. Somehow we have to make changes that will bring that down to zero.”~ Bill Gates (Innovating to Zero)
Bill Gates asked leading climate scientists what is needed to turn things around. They told him we need to cut global emissions to near zero. This sobering prescription sets the stage for his 27-minute TED Talk he calls Innovating to Zero. You can hear him directly in the video below. As you watch, pay attention to the way he uses math to present the scale of the problem and the solutions that are needed in response.
Inspired by the thinking behind Innovating to Zero, a special Edition of Atmosphere Monthly is now in the works. The focus will be on the importance of zero emissions targets for personal and global efforts to end the climate crisis. For this reason, the current issues are being scaled back.

“Until we get to ‘near to zero,’ the temperature will continue to rise.”
~ Bill Gates (Innovating to Zero)
Leading climate scientists say the upper safety limit for CO2 levels in the atmosphere is 350 parts per million (ppm). Atmospheric CO2 levels are now pushing past 390 ppm. They are rising faster than ever. Every extra part per million adds heat and stress to the planetary system that would not otherwise be there.
What will it take to stabilize atmospheric CO2 in the atmosphere? The IPCC explains:
A 50% reduction would stabilise atmospheric CO2, but only for less than a decade. After that, atmospheric CO2 would be expected to rise again as the land and ocean sinks decline owing to well-known chemical and biological adjustments.
What will it take to go beyond stabilization? What will it take to get atmospheric CO2 falling back to levels of less than 350 ppm? The IPCC explains:
Complete elimination of CO2 emissions is estimated to lead to a slow decrease in atmospheric CO2 of about 40 ppm over the 21st century.
This information is presented at CO2Now.org and Atmosphere Monthly by Pro Oxygen, an independent, Canadian enterprise. Pro Oxygen is working to promote carbon literacy for people and businesses around the world. The ultimate aim is to empower individuals and groups with information and tools that actually help people 'fix the atmosphere.' In short, that means practical steps that can lead to emission cuts deep and fast enough to get CO2 falling back below the upper safety limit for the concentration of CO2 in the atmosphere.
