Bill McKibben and 350.org Can Magnify and Speed Their Impact

Bill McKibben, leading the international climate campaign 350.org, urged an attentive audience at Natural Products Expo West to make a difference for the future of the planet. Over 5200 demonstrations, which circled the globe in 181 countries on October 24, 2009, show grassroots understanding of the need to reduce atmospheric carbon dioxide to no more than 350 parts per million. The current level of 390 parts per million, rising with no end in sight, spells catastrophe for life on earth as we know it.

The most significant part of the talk was McKibben’s answer to an audience question. One woman asked why 350.org does not include a truly sustainable diet as a critical action item in the campaign. She pointed out that a recent analysis by Worldwatch Institute demonstrates that 51% of greenhouse gases are directly traceable to raising animals for food.

The obvious solution to getting at least halfway to the goal of stopping climate change is simple, rapid, and no cost – eat a plant-based diet.

In his response, McKibben acknowledged that factory farming animals is a huge cause of climate change. However, he was not advocating immediate action to change diet. Instead, he advanced the idea that a carbon tax, once enacted, would make factory farmed animals so expensive that meat would be priced out of the range of most people. This would happen because people in the animal foods business would have to pay the “true cost” of their carbon impact.

McKibben also theorized that “grass fed cattle” could actually be helpful in reducing greenhouse gases. The theory is that, as large animals roam and trample vegetation into the soil, the ground itself stores carbon and keeps it from (more…)

Heavy Snows Are Signs of Climate Destabilization

“Global Warming” is Real, But a Misnomer

With a frigid winter chilling much of the country and heavy snows setting new records, people have an easy time concluding that global warming is just a myth. Maybe you, or people you know, think it’s a scientific theory that did not pan out.

Record snows lead the way in climate change

In fact, once you understand global warming, you may be alarmed that all the snow so far is just a taste of what is to come over the next decade. “Global warming” indicates that the earth’s temperature, on average, is rising. It does not mean it will always be hotter in every location on each day of the year.

“Climate destabilization” and “climate change” are both more accurate descriptors of the weather shaping up worldwide. Average temperature, evaporation, wind and ocean current patterns, and forests, among many other factors, determine the complexity of weather day by day. Over time, weather on each day forms the overall pattern that is climate.

We are used to a specific climate pattern throughout the year in different parts of the globe. As those patterns shift with rising greenhouse gas concentrations and subsequent higher average temperature, weather will become more extreme. Hot places will get hotter, but the cold will get colder. Droughts and floods will (more…)

Global Warming Uncertainty: Here’s Help

Where Does the Weather End and Climate Change Begin?

Weather is simple – rain, snow, hail, sun, wind, temperature. You can look out your window and see what it is right now.

If you’ve lived in the same place for a while, you can probably guess what the weather will be like in a few hours, too. You may even be able to predict ahead a day, and be right as often as the weatherman is. Unless you live somewhere with monotonous weather, though, you will have a hard time projecting the specific temperature and rainfall next week without help from scientific measurements.

Climate, in contrast, is a billion piece jigsaw puzzle. Climate is a pattern. Unless you keep detailed records over a long period of time, you can’t really tell for sure if the climate is changing. This is because the day-to-day weather

will bounce around all over the place.

You may have a hard time seeing the overall climate picture even for your own little corner of the world. So you can understand how much more difficult it is to determine climate patterns over millions of years for the entire planet. Yet a world wide network of scientists is engaged in this urgent task.

Climate scientists are not all on one formal team. Instead, these researchers are a loosely knit and shifting network communicating by email, published journal articles, data exchange, conferences, telephone, and meetings.

As with any group of people, climate scientists will have their differences of opinion. Sometimes a few of these researchers will say or do something that they wish would never be publicly aired.

Think about any team you’re a part of, whether at work, on a sports team, in a club or neighborhood committee, at your church, or even an informal circle of friends that meets for lunch every once in a while. Really, aren’t there differences of opinion, people who are less appropriate in their expression of ideas, and team mates you like more than others?

Scientists, being human, are no different than your own coworkers or teammates. This has no bearing on the legitimacy of their findings or research conclusions.

You have probably heard about the scandal arising from the theft of emails from some climate scientists at the University of East Anglia in England. Five reporters from the Associated Press read all 1,073 stolen emails and concluded the colorful language in these emails do nothing to undermine the overwhelming data for climate change.

Those who want you to believe that there is no climate change, that business as usual is just fine, fall into two classes. There are well-intentioned people who simply don’t believe the weight of scientific evidence. Remember, after Columbus crossed the Atlantic, there was no shortage of skeptics who still thought the earth was flat. Some people just have a hard time looking at information objectively.

The other class of people make money off telling you to ignore the world wide consensus of respected researchers that climate change is a dangerous threat. This group is on the payroll of “business as usual” industries, such as oil, utilities, and other polluters.

Who are you going to believe? And what action will you take? It’s impossible to sit on the sidelines. Every time you eat, you are choosing animal foods that accelerate climate change or plant-based nutrition that puts the brakes on the destruction of life as we know it. Look at this opportunity as your vote for the future – or against it.

Five Ways that Raising Animals for Food Accelerates Global Warming More than We Thought

In 2006, the United Nations Food and Agriculture Organization published the groundbreaking Livestock’s Long Shadow. This historical report focused attention on environmental facts that were long-known but studiously avoided by both consumers and policymakers.

Livestock’s Long Shadow documents the horrific environmental consequences of raising farmed animals for people to eat. Water shortages. Air and water pollution. Degraded soil. Deforestation. Extinction of wild plants and animals.

The list is heart breaking for anyone who cares about the future of our planet. I worry every day about the world my daughters are inheriting. How long

can we sustain even basic necessities on a plundered planet?

Most famously, this United Nations report documents that 18 % of greenhouse gas emissions can be directly traced to raising animals for food. This staggering impact is more than all transportation combined. You could scrap every truck, car, plane, and train on the planet – or you could stop raising farmed animals and have an even greater effect on climate change.

Now two respected researchers document that the impact of animal agriculture on global warming is almost three times worse that the UN estimated in 2006. The respected, independent nonprofit World Watch Institute published this analysis in their November/December 2009 magazine.

The study’s authors thoughtfully question what the United Nations left out or ignored. These pros have really done their homework. Their article demonstrates five major sources of greenhouse gas emissions from farmed animals left out of Livestock’s Long Shadow. The mistakes the authors found include overlooked sources of greenhouse gases, undercounted methane, and global warming contributors put into incorrect categories.

So what’s the bottom line? Over half – 51% – of global warming is directly caused by farming animals. You can have a direct, immediate impact on your kids’ future just by changing what you eat for dinner. Can you think of a single valid reason not to do this?

Changing what you eat is not nearly as hard as you think it might be. It’s not as painful as watching droughts, floods, disease, famine, and hurricanes rip people’s lives apart as global warming accelerates. Thank you World Watch Institute for these fearless insights. We don’t want to confront our comfortable habits, but we must.
