The future of the human species

February 25, 2014
By

Today’s headlines from the political left and right form a striking diptych that surely tells us something about the future of the human species. From Truthout comes this article, The March of Anthropogenic Climate Disruption, providing the sombre and sober truth about the state of the environment on planet Earth. While most of us do our best to ignore them, the signs of catastrophic climate change are all around us. This article does a good job of detailing several of the most recent signs and driving home the point that we are probably long past the point of no return…

Scientists begin to consider human extinction

December 23, 2013
By

Within the climate science community there is now virtually no debate that human-induced climate change is real and that it poses a serious challenge to the future of human civilization and the existence of many other plant and animal species on this planet. However, there is still plenty of debate among climate scientists over other questions, including the questions of just how grave and how immediate the threat of climate change really is. This recent article by Dahr Jamail is a summary of the some of the latest findings from those scientists who are most alarmed about the current situation.…

Climate change and capitalism

November 12, 2013
By

Scientists have been ringing the alarm bells about climate change for decades now, but the message, which is barely filtering through into the public consciousness, has yet to do anything to reverse the destructive path that human civilization is on. There are perhaps many reasons for this, but the crux of the matter is corporate capitalism and it’s control of the political process. Corporations are driven by the logic of maximizing profits at all costs, including costs to society and to the environment, and politicians are driven by the logic of catering to these corporations, on whom their political careers…

Do the Math (documentary)

July 20, 2013
By

Bill McKibben is one of the greatest environmental writers and activists of our time. In 1989 he wrote The End of Nature, which is considered by many to be the first book on global warming written for a general audience. Since then he has written countless articles, given hundreds if not thousands of public lectures, and is the main organizer of the 350.org movement to solve the climate crisis. One year ago McKibben published an influential article in Rolling Stone magazine entitled “Global Warming’s Terrifying New Math.” The thesis of the article is that there are three significant numbers that everyone needs…

Global greenhouse gas emissions chart

Global greenhouse gas emissions chart

Ecofys, a sustainability consultancy has put together a clear and well-arranged chart that maps worldwide greenhouse gas emissions by source and sector. It is based on data from credible sources such as the IEA, the EU Joint Research Centre, CDIAC, and the Global Carbon Project. One point worth noting is that while this chart analyzes the greenhouse gasses by source and sector, it does not show the varying contributions to climate change of these different gasses. For example, there is much less methane (CH4) being released into the atmosphere than carbon-dioxide (CO2), but CH4 is about 25 times more potent than CO2…

The climate change debate in brief

A new survey, published in the peer-reviewed Environmental Research Letters, a publication of the Institute of Physics (IOP), has definitively confirmed the scientific consensus in climate science literature: 97 percent of peer-reviewed papers agree that global warming is happening and human activities are responsible.  The survey, Quantifying the consensus on anthropogenic global warming in the scientific literature, examined some 12,000 peer-reviewed climate science papers and found a 97% consensus that humans are causing global warming. The work expanded upon an earlier survey of the literature by Naomi Oreskes, published in 2004, as well as an informal review conducted by James Powell, published on DeSmogBlog in 2012. Lead author of…

Renewable energy could provide 99.9% of all power by 2030

March 22, 2013
By

It is commonly asserted that even with massive investments, solar, wind and other renewable energy technologies could not possibly meet all of the energy needs of any industrialized economy. However, a recent study done by Budischak et al. debunks this piece of conventional wisdom. The study suggests that with an optimized energy production and storage network, up to 99.9% of all energy needs could be met using nothing more than currently existing renewable energy technologies–and at roughly the same cost of conventional energy production. The abstract of the study report reads as follows: We model many combinations of renewable electricity sources (inland wind,…

Obama vs. Physics (by Bill McKibben)

January 30, 2013
By

The subtitle of Bill McKibben’s latest piece for TomDispatch reads “Why Climate Change Won’t Wait for the President” and sets the tone for another very well written and well-reasoned article by one of the greatest environmental writers and activists. While it is worth reading in whole, here are some particularly interesting paragraphs that catch the essence of the article: […] And that’s always been the difficulty with climate change — the greatest problem we’ve ever faced. It’s not a fight, like education reform or abortion or gay marriage, between conflicting groups with conflicting opinions. It couldn’t be more different at a fundamental level.…

Canada shames itself once again in support of Israel

October 30, 2012
By

First a few background points on the legality of the Israeli settlements in the Occupied Palestinian territories (from Wikipedia):  1. The international community considers the settlements in occupied territory to be illegal. Israeli neighborhoods in East Jerusalem and communities in the Golan Heights, areas which have been annexed by Israel, are also considered settlements by the international community, which does not recognise Israel’s annexations of these territories. 2. The United Nations has repeatedly upheld the view that Israel’s construction of settlements constitutes violation of the Fourth Geneva Convention. International humanitarian law prohibits [an] occupying power [from transferring] citizens from its own territory to the occupied territory (Fourth Geneva Convention, article 49). 3. The International Court…

Garbage Warrior (documentary)

October 12, 2012
By

Michael Reynolds is a true maverick; he sees humanity marching toward the edge of a cliff and he’s not willing to go along with the crowd. Instead he uses his skills as a trained architect to show people that there is another, better way of living, one which is sustainable, ecologically beneficial, and 100 percent self-supporting. He builds homes–even entire communities–that are completely off the energy grid, collect water from rainfall, recycle waste, and are made from mostly garbage and recycled materials. It’s called “Earthship Biotecture” and it may very well be the most profound and practical solution to the pressing environmental challenges…

CO2 emissions drop, but natural gas won’t save us

September 18, 2012
By

Last month, the U.S. Energy Information Administration reported a drop in U.S. carbon emissions to a 20 year low, basically matching the carbon emissions of 1992. The media’s coverage of this report was brief and rather one-sided. Here are a few representative samples: Kevin Begos from the Associated Press: Many of the world’s leading climate scientists didn’t see the drop coming, in large part because it happened as a result of market forces rather than direct government action against carbon dioxide, a greenhouse gas that traps heat in the atmosphere. While conservation efforts, the lagging economy and greater use of renewable…

New ideas for addressing climate change

July 27, 2012
By

Bill McKibben, one of the leading environmentalists of our time. has a real talent for taking the latest developments in climate science and explaining their significance in terms that the average person can easily understand. His latest piece in Rolling Stone magazineis no exception. In it, he gives compelling, fact-based reasons for why the prospects for containing global warming are very dim. But he also presents a new idea that just might provide a glimmering of hope. McKibben suggests that the divestment campaign that helped to end the South African apartheid may provide the model for a public campaign to…

The sad state of affairs in Texas

By

The 2012 political platform of the Republican Party of Texas is available online here. The views expressed  in this document are both disturbing and depressing. Below are a few highlights.  1. On Education Controversial Theories – We support objective teaching and equal treatment of all sides of scientific theories. We believe theories such as life origins and environmental change should be taught as challengeable scientific theories subject to change as new data is produced. Teachers and students should be able to discuss the strengths and weaknesses of these theories openly and without fear of retribution or discrimination of any kind.    Knowledge-Based Education –…

Twenty years ago a 12-year-old girl named Severn Suzuki addressed delegates in Rio de Janeiro during the summit’s plenary session on behalf of the world youth. In the following segment DemocracyNow! revisits that passionate, prescient, and powerful and speech that “silenced the world for 6 minutes”.  Some quotes from the speech: Coming up here today, I have no hidden agenda. I am fighting for my future. Losing my future is not like losing an election or a few points on the stock market. I am here to speak for all generations to come. I am here to speak on behalf of…

A small sample of some the important things that have been said recently on the state of the climate crisis and the failures of political leaders to address the root causes or even acknowledge the seriousness of the problem: 1. Democracy Now interview with Bill McKibben (environmentalist, author, founder of the remarkable grassroots climate campaign 350.org) 2. Approaching a state shift in the Earth’s biosphere (ground-breaking article in Nature written by over 20 environmental scientists) 3. Is humanity pushing Earth past a tipping point? (a simplified, less technical summary of the aforementioned article in Wired magazine) 4. Democracy Now interview…

Living off the grid in Costa Rica

June 25, 2012
By

Al Gore popularized the idea that there is one profoundly inconvenient truth about life in the developed world, namely, that it is unsustainable. His point, which is now common knowledge, is that our societies and economies are based upon the consumption of fossil fuels, which release greenhouse gasses into the atmosphere, which in turn brings about a cascade of consequences that undermine the very lifestyles that we currently enjoy. In response to Gore, it should be noted that there is also one rather convenient truth that is easily overlooked, namely, that in certain parts of the world at least it…

Population control or population justice?

June 25, 2012
By

Over at the National Radio Project, another amazing example of independent media with a social conscience, there is a fascinating audio segment on the question of population control within the context of environmental sustainability (Population Control or Population Justice?). It is (one hopes) becoming increasingly clear that limitless economic expansion is not possible on a planet of finite resources and that if environmental catastrophe is to be avoided human societies need to radically overhaul their economies and abandon the fixation on economic growth. Hence the increasing interest in the concept of de-growth among ecologically oriented economists, people like Herman Daly and…
