I saw the movie "Cowspiracy" which claims that Animal Agriculture is the largest contributor to climate change -- it contributes 51% of all greenhouse gas emissions. I checked this after the movie and the UN FAO lists it at 11%, but a third party, "World Watch" recalculates it to 51 based on respiration and other factors. I judge the evidence overall to support the treatise that animal ag is unsustainable, but isn't respiration carbon neutral - feed plants store CO2 equal to what cows expel? -PH

Hi playitbackward,

First, I’m into adaptation - not carbon or emissions nuttery. I help governments reduce risks by changing environmental and development policies. Adaptation is the process of reducing impacts from climate change. It’s basically preventing natural disasters using climate science. Read a short summary here.

That said, the movie is clearly misleading and propagandist (thus the title). It’s not difficult to find the correct sources of information on sources of emissions, primarily of which is the IPCC’s Fifth climate assessment report on mitigation: Climate Change 2014: Mitigation of Climate Change.

How did they know the global average temperature in 1880? -a curious science follower
climateadaptation climateadaptation Said:

Hey anon,

Great question! Simplest answer: thermometers. Simple instruments such as thermometers and barometers have been used for centuries. Governments began to collect data from these instruments beginning in the early 1700s. (There are early data sets, but these focused on local or route specific locations rather than globally. For example, shipping companies collected ocean temperatures during the 1600s along specific routes to report conditions to insurance companies.).

The old-school instruments were placed in locations all around the world (locations ranged from trees, church steeples and clocks, tall poles, cliff faces, to just stuck in the ground). Governments collected the temperatures typically for military, farming, and shipping purposes.

The U.S. Weather Bureau, established in 1735, was sporadically managed by a few individual states (rather than the Federal Government). The bureau collected local information - not global.

In 1814, the U.S. Federal Government established the U.S.’s first nation wide weather service. Army doctors and ‘war’ hospitals were instructed to keep diaries of local weather. But, again, this was not a global system.

In 1870, President Ulysses Grant established the U.S. National Weather Service (NWS):

The beginning of the National Weather Service we know today started on February 9th, 1870, when President Ulysses S. Grant signed a joint resolution of Congress authorizing the Secretary of War to establish a national weather service. This resolution required the Secretary of War:

to provide for taking meteorological observations at the military stations in the interior of the continent and at other points in the States and Territories…and for giving notice on the northern (Great) Lakes and on the seacoast by magnetic telegraph and marine signals, of the approach and force of storms

After much thought and consideration, it was decided that this agency would be placed under the Secretary of War because military discipline would probably secure the greatest promptness, regularity, and accuracy in the required observations. Via NOAA

The NWS worked internationally. It collected data from its own instruments, and also from data shared by other countries, such as Denmark, France, India, and the U.K.

The NWS’s information was collected over time, and digitized into big data sets. These sets are used today!

The chart below shows temperature data over 1,000 years. (NOTE: This chart is from wikipedia entry “Temperature record of the past 1,000 years." I do not endorse this chart. I’m posting for illustrative purposes to help answer anon’s question about records from 1880).

Note the black line (far right). It shows collected instrument data from 1850 to 2004. Data prior to 1850 is collected by climate proxies.


Finally, if you’re interested, you can read about the weather data sets collected in the 1850s. This paper, Uncertainty estimates in regional and global observed temperature changes: a new dataset from 1850, covers the history of that data, as well as issues with using it in modern climate models.

Hope that helps!



Chemical breakdown of food. Clever. Via Revkin.

Related to Obama’s voracious support for ethanol. See my earlier post on how the president’s policies supporting ethanol fuel is devastating conservation land across the United States.

I’m not into the tone of this article, but thought y’all would appreciate knowing about it.

Excellent reporting by Carey Gillam of Reuters. Gillam dives into how the ranchers and families will cope with the losses. The federal government shut down comes into play, as does a tax-payer subsidized bailout for their losses under the - imo - ridiculously bloated and unfairly skewed US Farm Bill.

The story of why nearly 100,000 head of cattle perished is a complicated one, one not just due to freak weather. And Gillam really nails it.

What are your thoughts on vegetarianism/veganism? Especially taking into consideration the possibility of a (worsening) global food crisis.

Hey anon,

I generally avoid food posts, but am interested in the infrastructure that supports food systems.

One part of my current contract with USAID is a resilient wheat project in Kazakhstan. Kazakhstan is the 6th largest wheat producer in the world and mostly exports to east and central Europe, the Caucuses, and Asia.

Farmers there are facing three main issues: extreme temperature swings, which are increasing in frequency and causing terrible economic havocs; when to plant their crop, a problem because the planting timing and growing seasons are shifting; and shortage of storage silos for the wheat, especially in bumper seasons.

This last part - where to store the wheat - is probably the biggest issue developing countries (DCs) face with respect to dealing with climate impacted growing seasons. The farmers in Kazakhstan don’t trust the government, nor their seasonal forecastings. Nor do they (generally) reliably purchase crop insurance. So, the farmers tend to plant “when my neighbor plants,” put their finger to the wind, and hope for a good season. It’s very risky, and very unstable. They lose when there is a bad year, due to bad timing of planting, storms, droughts, etc.

But, and back to your question-ish, some years produce so much wheat that the farmers actually lose money. The reason is two fold. First, they lose on market price. The market price goes down when there is an abundance of wheat, it goes up when there is a shortage. The other problem with high-volumes is that there’s no storage system or infrastructure to support a storage system. Thus, all the silos get filled very quickly when all farmers produce record crops - when the silos are filled, the wheat is literally thrown away. 

Tl;dnr, “the food crisis” is typically not due to a bad weather year, but due to inefficiencies in distribution. There’s plenty of food grown in the world. Climate change will affect the patterns of growth, but not to such an extent that the systems cannot adapt and adjust.

Getting crops from farm to table is the real issue…

Mark Bittman visits an industrial tomato farm in California. I like that he swipes at ‘heirloom’ tomatoes. But his admiration for sustainable farming permeates the entire piece.

I’VE long wondered how producing a decent ingredient, one that you can buy in any supermarket, really happens. Take canned tomatoes, of which I probably use 100 pounds a year. It costs $2 to $3 a pound to buy hard, tasteless, “fresh” plum tomatoes, but only half that for almost two pounds of canned tomatoes that taste much better. How is that possible?

The answer lies in a process that is almost unimaginable in scope without seeing it firsthand. So, fearing the worst — because we all “know” that organic farming is “good” and industrial farming is “bad” — I headed to the Sacramento Valley in California to see a big tomato operation.

I began by touring Bruce Rominger’s farmin Winters. With his brother Rick and as many as 40 employees, Rominger farms around 6,000 acres of tomatoes, wheat, sunflowers, safflower, onions, alfalfa, sheep, rice and more. Unlike many Midwestern farm operations, which grow corn and soy exclusively, here are diversity, crop rotation, cover crops and, for the most part, real food — not crops destined for junk food, animal feed or biofuel. That’s a good start.

[S]everal obstacles may prove to be insurmountable for the near - future commercialization of in vitro meat. The legacy of consumer wariness for foods produced through biotechnological intervention, as encapsulated by the prolific debate over genetically modified foods, coupled with the fetishization of the process of slaughter as a component of meat quality compounds the issue of meat production. Nevertheless, as will be discussed, if in vitro meat proves to be successful it may have tremendous promise that translates to several areas of contention for animal rights activism.

I read another article this morning about hive disruption syndrome and about bee-dieoffs in general. The article framed the issue in a wider context of a 'sixth extinction.' As a layman I'm generally sold on these theories, despite their grim outlook. Assuming (as I do) that they're probably the result of anthropogenic climate change, what do you think the proper adaptation methods will be, considering the necessity of honeybees in pollinating most crops around the world?
climateadaptation climateadaptation Said:

Hi exlegelibertas,

Great question and I did a little research for you (learned a lot, so thanks!).

The so-called “sixth extinction” theory has been around for a while. I’d avoid reading about it, since it’s all doom. Still, adaptation strategies for bees and other pollinators are only now being taken seriously. 

Keep in mind that environmentalism is ‘stewardship’ - it requires long-term thinking, far beyond your life-time. Solutions take time and decades of research and testing. So, managing impacts are part of a long transition…

Most adaptation strategies and responses are part of bigger plans that deal with ecosystems and agriculture, so they’re more likely to be a chapter in larger documents. Here a few resources:

A dog walks on cracked ground at the Las Canoas dam, some 59 km north of the capital Managua on April 26, 2013.. A large area of the dam has been dry since last February, as most of its water have been used by rice farmers for their crops, affecting around hundreds of peasants living in the area, according to local media.
