Making the Case

enviro-goreThe New York times had an interesting op-ed last Monday by Paul Krugman, Cassandras of Climate Change. It contains a few quotable bits, but they’re large and the piece is short, so I’ll leave it to you dear reader to follow the link.

Krugman mentions Mr. Gore, and his film The Inconvenient Truth, which never quite seemed to live up to the hype… but I do have high hopes for The Age of Stupid, if it ever makes it into general distribution that is. To be honest though, what’s really been driving home a sense of urgency for me recently is PBS, specifically five year old re-runs of Scientific American Frontiers!

A recently aired segment in “Forever Wild?“, which I previously mentioned in passing, makes an excellent case for not mucking with the atmosphere. “Hot Times in Alaska” examines a number of disturbing changes well-underway that even those familiar with the global warming might not be aware of. And a third episode, “Hot Planet – Cold Comfort,” looks at the merits of another movie, The Day After Tomorrow.

All three episodes can be viewed for free online, and are worth reviewing in your spare time, or passing on to others who still don’t quite understand what all the fuss is about. “Hot Times” also happens to be showing Friday night at 9 on GBH Kids.

Climate Change Ranks Last in US Poll

While the evidence keeps piling up on the already devastating effects of climate change, a recent Bloomberg Poll rates climate change as dead last, with only 2% or respondents ranking climate change as the top issue facing our nation.  It is clear that the economy and health care are vitally important issues to address, but the abysmally low ranking of climate change reflects the success of disinformation coming from industry and media that has sown confusion in the public on the science of climate change.

Recent findings highlight that many people feel helpless about Climate Change, which leads to both apathy and inaction, and long term threats are difficult for people to assess.  Climate change is an issue not easily understood by the public due to the complexities of the climate, feedback loops, and tipping points.  At the current rate of greenhouse gas emissions, the MET Office Report estimates that another 4 degrees Celsius could be in the pipeline by 2060, leading to major droughts, sea level rise, and ecosystem collapse.  The original proposal to keep the globe from warming by 2 degrees by the end of the century is now seen as a “lost cause”.  With Copenhagen just two months away, it is important for the public to better understand climate science and its impacts.

Scientists Speak out on the Climate Emergency

Warningco2 Dr. Melanie Fitzpatrick, Climate Scientist with the Union of Concerned Scientists, shared sobering data with concerned citizens at a Cambridge City Council special meeting on September 24th, as part of the city’s efforts to better understand the climate change emergency and respond at a scale proportionate to the emergency and consistent with the city’s own Climate Protection goals for 2010.  Dr. Fitzpatrick emphasized that climate change is now occurring faster than the worst predictions of the IPCC (Intergovernmental Panel on Climate Change) models and cited evidence including that the melt season is lasting 1 week longer in the arctic, a 9% reduction per year in arctic sea ice, winters warming 4 degrees in the northern hemisphere, and record global sea temperatures for the last three months.  Scientists are now estimating that some of the feared tipping points are decades away rather than centuries.  If we were to stop emitting greenhouse gasses today, there is at least another 1 degree of warming in the pipeline and we could potentially see an additional 4-7 degrees Fahrenheit by the end of this century without major emission reductions.

While tipping point scenarios are still in the future, Dr. Jill Stein with the Physicians for Social Responsibility testified that there are already 300,000 deaths annually attributed to climate change due to record flooding, droughts, increased storm severity and occurrence, spread of infectious disease, and impacts to food and water supplies.  For example, major flood events have increased four-fold in North America and six-fold in China compared to the century average.  On a positive note, Dr. Stein related that by addressing climate change we will improve health and quality of life indices.  The United States spends $2 trillion per year on medical expenses in which 75% goes to preventable chronic diseases.  Investing in more walkable communities with local healthy food sources would reduce greenhouse gas emissions and improve our collective health. Fighting climate change would require our economic and social systems to take a long term view when planning for today.

Just consider that the majority of home owners purchase fire insurance, even though your risk of fire loss is very low– less than 1 percent or 1 fire in every 250 years.  Under our current greenhouse gas emission rates, the chance of a catastrophic tipping point occurring like Amazonian desertification, Greenland Ice sheet melt, or the disruption of the Indian Monsoon now has a fifty percent chance of happening which would have devastating effects on the economic and social welfare of millions of people.  Dr. Ackerman, Environmental Economist with the Stockholm Environmental Institute at Tufts University pointed out that to delay action would have disastrous socio-economic consequences for civilization.  Dr Ackerman  summarized four key ways to view long term economic questions:

  • Your grandchildren are Important! Current economic analysis has a high discount rate for future generations.  This would be equivalent to saying that your prodigy is more important than your grand or great grandchildren.
  • If you insure your home and car for relatively low risk harm, we should invest in higher level risk like climate change.
  • Some things do not have dollar values.  What is the value of a life or an ecosystem?  Under the Clinton administration a human life was valued at $6,000 and the Bush administration lowered it to $4,000.
  • It is better to spend your money on prevention rather than treatment.  Climate prevention could be spent on creating green jobs, developing new technology and industry.

Dr. John Sterman, an economist with the Sloan School of Management at MIT concluded that we should not wait to see the major impacts from Climate Change, as the stakes are too high and we  will have likely triggered major tipping points.  Dr. Sterman and the other panelists agreed that climate change can not be fought primarily with high tech solutions, but must include social participation that finds creative solutions both at the national and local level.  Dr. Sterman in collaboration with Sustainability Institute, Ventana Systems, and MIT has developed a climate simulation to help you use a scientifically rigorous model to set a goal for CO2 in the atmosphere, explore what it will take to reach that goal and to empower you to share those insights with others via graphs and explanation in order to make such actions happen.  Discover Climate Interactive, their online community that creates, shares, and uses credible models, accessible simulations, and related media in order to improve the way leaders and citizens around the world think about the climate.

Let’s Bury It?

In New Haven, West Virginia, the Mountaineer Power Plant is about to embark on the world’s first attempt to capture and bury CO2 from a coal-fired power plant (NYTimes). As early as this week, fluid CO2 will be pumped into sandstone 7,800 feet underground and then into dolomite 400 feet below that; the liquid carbon dioxide is 30 to 40 feet high and hundreds of yards in length. The plan is to inject 100,000 tons annually for two to five years with the possibility of capturing 90% if Congress finds the technology economically feasible.

Initially sparked by political pressure to limit the amount of CO2 released into the atmosphere, these plants are now faced with skeptics, scientists and environmentalists alike, who are concerned about the safety and long-term impact this new process could have. Specifically, CO2 that’s injected into the Earth can filter into the ground water increasing the levels of carbonic acid. Other skeptics are concerned about the long-term pressure that could build as a result, leading to increased earthquakes. The EPA has discounted the risk. Either way, the bigger picture amounts to our continued dependence on fossil fuels for global energy. Until Congress understands the benefit of renewable energy both as a power source and economic stimulant, we will instead be faced with daunting and frightening “solutions” to climate change—like the one taking place in New Haven, WV—which are anything but.

Carbon Release Inventory

After releasing a report on the issue on Monday, yesterday the EPA finalized rules that require the nation’s largest polluters to report on carbon emissions. The program is similar to the established Toxics Release Inventory (TRI) program, which has been an immensely useful tool for researchers and watchdog groups, and also demonstrated to reduce emissions without further regulation. However, the picture is of course not as simple as that, some feel that the regulations have too many loopholes.

Meanwhile, NewScientist recently noted that if we shared more, we’d need less stuff and that this would dramatically decrease our impact on the environment; economies of scale, et cetera.

The Age of Stupid

DUH

Although the name “The Age of Stupid” brings to mind Gary Larson’s strip “Awkard Age,” or Mike Judge’s “Idiocracy,” the film is a docu-drama about global warming. In it a mid-century man looks back and wonders why did not act more swiftly. Tomorrow is the world premiere, with a simulcast if the festivites and interviews of prominent figures, plus a showing of the film itself. Alas, it does not seem to be entering wide circulation afterwards?! Luckily, there are a number of showings in the area.

Biosphere 1: The Great Experiment

Bio-Dome

Laymen can have a tough time following complex stories such as climate change, particularly when the media and opponents characterize new findings or revisions as examples of uncertainty, rather than of science as evidence-based consensus building. This false discord is often then used to lend weight to “alternative” views. The American public is not unique in this regard, and recently Australian climate scientists have had to cope with similar issues as parliament began debating their own climate legislation.

Contributing to this problem, is a general lack of awareness of what the current state of climate research is. Models and geoclimatic records—like tree or ice cores—seem to receive the most coverage, as well as speculation based on freak weather events, even though weather is not climate. This is somewhat understandable if one still truly believes there is a debate about the existence of rising CO2 and a related warming trend, yet there is not. Consequently, the wide variety of direct experimentation on the effects of these phenomena receives little attention.

After unforeseen difficulties in regulating its atmosphere caused the initial experiment at Biosphere 2 to be closed down, administration of the facility was passed on to Columbia University and now the University of Arizona. Both universities have used the space to conduct unique experiments (video link) into the effects of increased atmospheric carbon dioxide on a variety of ecosystems, and the news is not good.

Yet whether or not “US crop yields will wilt in heat,” it is indisputable that burning fossil fuels produces CO2. Meanwhile, scientists continue to gather evidence that “carbon fertilization,” or increased plant growth due to greater availability of carbon dioxide, many not be the boon we might hope for. Just last month, a paper was released indicating that the nutritional quality of wheat decreases when grown under high CO2 conditions. The more we learn, the more it becomes clear that we’re running great risks by treating the atmosphere as a limitless garbage dump.

On a related note, Presidential science advisor John Holdren recently gave a nice interview at New Scientist, wherein he answers many questions about ACES and global warming.

350: The new Climate Target?

NASA Climate Scientist James Hanson and  national climate activist Bill McKibben are pushing to move the climate debate from keeping global emissions from surpassing the original danger zone of 450 parts per million as recommended by the IPCC, to instead recognize 350 parts per million as the new limit that should not be passed.  Their recommendations come from recent findings by James Hanson, that indicates that climate change is happening faster than expected and feedback loops have a greater impact on climate than originally hypothesized.  At 450 parts per million, we potentially run the risk of returning the planet  to conditions when it was largely ice-free, when sea levels were higher by more than 200 feet.

The 350 movement is gaining steam with a top UN Scientist signing on in support.  Currently, CO2 emissions are now at 387 parts per million and it is expected by 2100 emissions could reach  between 400 and 1,000 parts per million.  To get back to 350 parts per million, industry, governments, and individuals will have to go way beyond the proposed reductions which are already meeting incredible resistance here in the US and overseas.

To learn more about the movement visit 350.org and on October 24th individuals and groups across the globe are taking action to build public awareness on the importance of 350 ppm and leveraging meaningful political change.  The city of Cambridge has also recently passed a resolution recognizing the climate change emergency.  Cambridge residents can weigh in on climate change at the Climate Emergency Forum on September 17 at the Cambridge Community Center at 7 PM and a city council hearing scheduled for September 24th.

White Roofs Everywhere!

Want to know a quick, relatively easy way to reduce global climate change?  Paint your rooftops white. Yes, it’s true.The way rooftops—as well as roadways are currently constructed (using dark asphalt and color scheme) creates a feedback loop of heat absorption in the atmosphere. Dark colors absorb heat, meaning less is reflected back into space. It’s a dangerous cycle. According to Professor Steven Chu, the US Energy Secretary, white roofs could be a relatively inexpensive way to cut carbon, but are also doable with immediate results. In fact, Dr. Chu commented that “lightening roofs and roads in urban environments would offset the global warming effects of all the cars in the world for 11 years” .

One could argue however that producing all the toxic paint used to complete such a massive intiative would out-weight the benefits. It’s also not necessarily a long-term solution. Furthermore, there’s the case for “living roofs” that not only absorb heat but also act as carbon sinks. Of course green roofs—they are more commonly known—take much more time, money and effort, whereas painting is a relatively easy process. Either way, acting fast yet thinking long-term is the only way to truly battle climate change. Manageable steps with gigantic impact, such as lightening roofs and roadways, is something everyone can take part in today. Perhaps, then, it’s a good place to start.
