I Can See (CO2) for Miles and Miles…

I Can See (CO2) for Miles and Miles…

| 4.05.2010

Hello to all you citizens of Earth and readers of Sadhana Forest news. Hope everyone has survived the glorious spewing of Icelandic volcanoes!!

Over the next several posts, I am planning on laying out in simple prose and imagery (with a few interesting links-I hope!-mixed in the pot) prominent indicators of runaway greenhouse gas emissions and the global heating which has begun to ensue as a result. It is crucial that the global citizenry get an easy-to-understand and concise picture of how we know that human activity is dramatically altering the Earth’s life-supporting systems.

Really, Really Elevated and Historic CO2 Levels in Life-Sustaining Atmosphere

At the present moment, the Earth’s lower atmosphere- responsible for providing us with just the right mix of molecular gases to sustain human life for the past 200,000 years plus- contains about 390 PPM of carbon dioxide. Carbon dioxide is the most prevalent and abundant greenhouse gas produced by humanity and has been released in ever-increasing quantities above ‘normal’ levels since the Industrial Revolution began. In fact, research released last year showed that we haven’t seen levels of CO2 this high in 1.5 million years! While the greenhouse gas effect is critical to supporting life on this planet, too much of a hot blanket can be incredibly suffocating to humans, other animals and plants, and ecosystems which have thrived in a relatively stable climate until very recently.

Here is a graph that shows the worldwide atmospheric levels of CO2 over the past 800,000 years, based on research conducted using ice core samples. Note the steady ups and downs of carbon dioxide levels until the past couple hundred years, when we dramatically shoot up to the current concentration of nearly 400 PPM, as well as the speed in which the CO2 increase has occurred. Coincidentally enough, these last couple hundred years coincide with the Industrial Revolution and the advent of fossil fuel combustion! :

And, here is a snapshot of recent CO2 emissions data produced by the National Oceanic and Atmospheric Administration, which releases official climactic and meteorological data on behalf of the United States government. The graph shows CO2 levels in the atmosphere- as measured in Mauna Loa, Hawaii, United States- on an annual basis, beginning in 1958:


Hmmmm. Don’t really see any downward trend at all there.

A grand experiment is being conducted, where we are testing how much of a very heat-absorbent gas we can put in the atmosphere before enormous, worldwide destruction can occur. And this experiment has never been conducted with human life on the planet. I can’t wait to see the results (odds are, Mother Nature will still be standing…us…?)!

Peace for now!


P.S. Some British researchers enjoyed some April showers last month. At the North Pole.

Teamwork! Come on Now!

Greetings to all you beautiful Sadhana-ites on this bright blue and green globe!

First things first, I want to congratulate and express my awe and gratitude to the Rozin family for taking the Sadhana Forest model to Haiti! This recently devastated and long-suffering nation could truly use the kind of sustainable and restorative project that Auroville has had the benefit of hosting for the past several years. In a country where nearly all forests have been decimated up to this point in time, Sadhana Forest can truly begin to make a difference in helping to restore this lost ecosystem and assist Haitians in building self-sustaining communities that are also adaptable to the effects of global warming. And, of course, much love goes to all the long-termers and other volunteers who have traveled to Haiti to get the project up and running!

Now…so much of the attention today surrounding the global heating problem focuses on carbon emissions, carbon footprints, political wrangling amongst the nations of the globe, the ”failure” of Copenhagen, errors in the Nobel Peace Prize-winning reports of the U.N. Intergovernmental Panel on Climate Change, etc, etc, etc..All of these issues are,of course, important and hugely relevant to the climate disruption issue. But what often gets lost in the shuffle of this enormously complex and far-reaching pickle humanity and its fellow creatures find itself in is the on the ground adaptations necessary for the common folks across the globe.

There is nothing that we can do alone, as an individual human being, to combat the effects of locked-in and future greenhouse gas warming (according to a recent letter in the peer-reviewed journal Nature Geoscience, Earth is locked into an average worldwide temperature increase of about 1°C or a bit less over pre-Industrial Revolution levels even in the incredibly unlikely event we were to cut our carbon emissions to zero immediately. And, this level is based off models used in the U.N. IPCC climate change report of a few years ago, which did not take into effect possible positive feedbacks such as Arctic methane release). We must help and assist one another, to further extend our bonds of empathy to fellow humans and to all of Earth itself, so that we can thrive and lead infinitely more peaceful lives. A worldwide consciousness is beginning to awaken with regards to the pollution and other forms of environmental destruction that humans have wrought. Just look at the activist groups who attended the UNFCCC negotiations in Copenhagen. Or the 350.org day of action-designed to draw awareness to a goal of achieving 350 ppm CO2 in the atmosphere- in October 2009, which Sadhana Forest participated in by way of an awesome morning of TDEF tree planting!


This is by no means a lightning-quick shift and much of humanity and other creatures on the planet will, and already are, facing long-lasting effects of climate change. But we can and must share our hearts and knowledge with those throughout the world, especially those in the Global South who have to adapt and mitigate to global heating’s effects, despite causing very little of the greenhouse gas problem. I am going to highlight some sweet projects that focus on bettering the lives, in a clean and non-polluting manner, of folks who may not otherwise have the resources to do so much:

America does have some awesome people, despite some thought to the contrary

A group of young students at Harvard University in Boston, USA, have developed a soccer ball that stores the motion energy produced while kicking the ball to use as electricity later! And all you have to do is kick the ball around! According to the above article, 15 minutes of use is enough to light a bulb for 3 hours!

Man goes back to roots, literally plants roots. OF A MILLION TREES

This Ethiopian-born, American citizen went back to his country of birth and discovered his home had been severely deforested. A crusade to mega-plant trees was launched and 1 million trees on 11,000 acres were planted.

I’ll trade you several fuel-efficient wood stoves for a solar system

A retired professor from Brandeis University in the United States encourages villagers in Tanzania to purchase very fuel-efficient, cleaner burning stoves (ala Sadhana’s rocket stoves!) and receive a small solar system that charges a battery for lights, cell phones, and other household items. Cool! And the amount of trees, carbon dioxide, and soot/”black carbon”is reduced. Win Win Win!

Global Warming: The Sobering Truths for Humanity without Action

Here is a post of our great friend Josh Diamond, back in the United States after an unforgettable time in Sadhana Forest.

Global Warming: The Sobering Truths for Humanity without Action

Greetings and Happy New Year to Sadhana Earth!

After a long break from the Sadhana blogosphere and a strictly physical (spiritual remnants remain amidst the bananas at Sadhana) move back the West Coast of the United States, I have been asked to return with my form of global heating enlightenment. Much love to Aviram and Yorit for allowing me to write for the Sadhana Forest web page

Rather than delve into a specific issue of interest in the global warming and global warming policy arena in my first post in some time, I want to provide readers a helpful look at what basic challenges humanity faces due to global heating’s effects. I am providing a link to a very thorough and straightforward summary from the Climate Progress blog of the multitude of ecological harms that could occur by the end of the 21st century if worldwide greenhouse gas pollution emissions continue at/around their current levels:

An introduction to global warming impacts: Hell and High Water « Climate Progress

Mother Earth will respond, and is (note: rapid melting of glaciers from the United States to the Andes of South America to the towering Himalayas of India and Nepal, years-long drought and immense dust storms in Australia, prolonged drought, followed by torrential monsoon rains in southern India, et al) currently, to the heat-trapping waste we put into her lungs.

And in case you in Sadhana cyberspace are sitting in the immense cold sweeping much of Europe and the United States, don’t worry:

GLOBAL WARMING STILL HAPPENING EVEN THOUGH IT IS WINTER IN SOME PARTS OF THE WORLD. CLIMATE CHANGE IS ALL ABOUT AVERAGES, SILLY!

In my next post, I hope to lay out simply what the Copenhagen Accord reached at the United Nations Framework Convention on Climate Change meeting in December means and why, despite the claims of many, hope is not completely lost to reach broad international agreement on greenhouse gas reductions.

Love and Peace for now!!

A Potential Step Forward in Climate Change Treaty Talks

| 27.10.2009

Bonjour Sadhana Forest World !

As the process of securing a strong and ambitious greenhouse gas reduction and global warming mitigation/adaptation treaty moves along quite slowly before the U.N. talks in Copenhagen (December 7-18), Brazil has put forth a potentially game-changing proposal. The president of Brazil, Luiz Inacio Lula da Silva, has agreed to slash the deforestation rates of his nation by 80% of its present levels by 2020. This commitment, if pursued to its fullest, would prevent nearly 5 billion tons of CO2 from entering the atmosphere and dramatically cut the greenhouse gas emissions of Brazil, as deforestation is their major cause of CO2 release and accounts for one-fifth of global carbon release.

From a humanitarian perspective, preserving the remaining rain forest in Brazil would maintain the home and livelihoods of the people that have depended on the Amazon for so many years. It could also  greatly lessen the use of incredibly biologically rich lands for livestock (accounting for upwards of 20% of global carbon emissions)  and biofuel production (largely going to Western industry and automobiles), which only serve to create further greenhouse gases emissions through methane release and lost carbon uptake from the destruction of forests.

This commitment from Brazil sends a strong message to the international community that global nations from across the economic spectrum can come together to work for a tough and fair climate change treaty. As countries such as China, India, and Brazil grow ever faster, and the demand for energy continues to rise, it is thought that most emission increases will come from these nations over the next several decades. Thusly, moves towards prevention of greenhouse gas emissions in these nations are essential to any effective post- Kyoto climate treaty. But those countries in the Global North, which are responsible for the majority of carbon emissions since the Industrial Revolution, have a responsibility to quickly mitigate their own fossil fuel output drastically and provide financial and technical assistance to those nations who will be most dramatically affected by global warming’s consequences.

Human-powered global warming will (and is) affecting every human and organism on the planet. Efforts like Brazil’s deforestation plan- albeit just one piece of the puzzle- show that the world’s nations can, and will have to, work in unity to maintain a livable Earth for all creatures.

We are Truly in Historic Times

| 21.10.2009

Ahoy Sadhana Foresters on this Big Blue Dot!

I came across a stunning article recently, posted on one of my favorite (and incredibly informative) climate change blogs Climate Progress, that I wanted to share with you:

Levels of Carbon Dioxide Today at Levels Not Seen in 1.5 Million Years

Human beings are at a stage in our existence that can be considered to be globally historic. So historic, in fact, that the climactic state in which we find ourselves currently in has not been observed on the Earth for nearly the past 1.5 million years! When last we saw greenhouse gas concentrations at this consistent level -currently at around 387 parts per million (PPM)- average temperatures around the globe were 5-10 degrees F (2.78-5.56 degrees C ) warmer and sea levels were 75-120 ft. higher, according to the above article.

We have managed to manipulate our atmosphere to an overheated condition not seen since over million years before Homo Sapiens came to be. And all of this has occurred in the past 200 + years since the inception of the Industrial Revolution. This is an incredibly fast rate to have injected this amount of greenhouse gas into our atmosphere, especially when you consider, as the article notes, that CO2 levels consistently hovered around the pre-Industrial level of 280 PPM 1.5 million years prior to the Industrial Revolution. Earth is now nearly 90 PPM above this nearly million year long average rate, and it only took us 200 years.

The time to act is now. Leveling off and then dramatically reducing our carbon atmospheric input over the next several years will be essential to keep future generations of animals and plants, as well as ourselves, from the most catastrophic global heating has to offer.
