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.

Let’s aim for 350 Parts Per Million of carbon dioxide in the atmosphere

| 24.10.2009

Hello lovely Sadhanaites !

I will keep things brief for once on this blog. Today was the International Day of Climate Action, organized by the group at 350.org. People from 181 countries across the world, including us at Sadhana Forest (check the News page for more!) sent visual messages to media and leaders across the world that we want to stabilize at 350 PPM of carbon dioxide in the atmosphere from our current level of 390 PPM. Though this figure is incredibly ambitious, we should at least set ourselves to eventually meet this target for future generations by beginning to deploy clean energy technologies,  practice reforestation, and  employ ecologically sound agricultural practices.

Today was a call to action for those setting greenhouse gas reduction policy across the world to recognize that global citizens want and demand the most ambitious targets possible for a climate change treaty at Copenhagen in December!

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.

The Very Present Face of Global Warming

| 18.10.2009

Greetings to the Sadhana Forest World!

I feel as though the effects of human-induced climate change on our planet are very often presented to people by mainstream media sources  as occurring in some vague, distant future. And it is true that Mother Earth will be feeling the effects of our fossil fuel spewing ways for potentially hundreds of years down the line if we do not take drastic actions to cut our greenhouse gas emissions soon (there is already a 30 year lag between when a carbon dioxide molecule enters the atmosphere and when the associated temperature increase occurs, meaning we won’t feel the effects of what we put in the atmosphere in 2009 until 2039). But the abnormal effects of human actions are very much present in the here and now.

A recent Reuters article on the very rapid melting of Kashmir’s largest glacier is just one of the many illustrations of the current consequences of our warming ways.

Keeping in line with the theme of glacier melt, here is a story from earlier this year regarding the melting of (what was once) the world’s tallest ski area in the Bolivian Andes.

Chacaltaya Glacier (R.I.P.) in Bolivia

Global “heating,” as British scientist James Lovelock now refers to our climate situation, is having drastic effects on people and their environments across the world. Today. But, mitigation and adaptation techniques are necessary and in our hands if we choose to turn back our carbon-heavy ways in the next 5-10 years.

A global effort is required. A shift in consciousness towards oneness with the Earth is required.

Talk soon.

Biochar the Great!

| 10.10.2009

Namaste Sadhana Globe !

I wanted to write a little something about a possible tool in our Earthly kit to help slow down the release of carbon dioxide into the atmosphere,  provide a closed loop source of energy, and improve greatly the fertility of soils:  Biochar(coal)!  A triple whammy that could potentially have a great impact on Mother Earth.

Biochar is what remains of organic material (forest debris, agricultural waste, animal manure, grass clippings, etc.) after being put through a controlled “burning” process in which oxygen intake is almost fully suppressed. This process, called pyrlosis, releases just a fraction of the greenhouse gases that normal, open-burning techniques produce as the near lack of oxygen does not allow combustible molecules like carbon monoxide and carbon dioxide to form. As well, gases such as hydrogen are emitted as a result of the pyrolysis process that,with proper equipment, can be then used to produce energy/electricity for buildings. Hence,  a closed loop in which all aspects of the char are used.

The tangible remnants from pyrolysis  produce a very nutrient rich charcoal that can then be applied to the soil, in a process similar to what Amazonian Indians had done hundreds and thousands of years ago with their methods of producing biochar. Today, one can see these soils- called ‘terra preta’- and how they still retain the rich composition that had existed so many years ago.

And most importantly from a climate change perspective, the production of biochar locks carbon emissions into the soil for an indefinite period of time rather than allow for normal decomposition that releases huge quantities of greenhouse gases from biomass to the atmosphere. Livestock waste, forest debris remnants, gardening waste, and other forms of organic matter from the human lifestyle can be turned into a useful material to hold in carbon, enrich soils, and potentially provide clean electricity !

Here is a wonderful overview, along with more links on the matter, from an environmental blog which I read frequently and is very comprehensive in its coverage of environmental issues: Gristmill.

That’s all for now! Peace and love!
