Getting Flaky

 

Snow has always been more problematic for movie sets than rain, but when the filmmakers and their special effects people do it well it creates an atmosphere for viewers that suspends their disbelief to the point of not noticing smaller details, like how the snow fallen on performers doesn’t appear to melt quickly when they go indoors, where it is presumably warmer than it is outside. All sorts of obstacles dictate the use of fake snow for movies rather than the real stuff, from warm weather outdoors to shooting scenes indoors on sound stages. Real snow also compacts underfoot, making it impracticable for filmmakers to get more than one or two takes in one spot outdoors even when they go to the trouble of brushing over footsteps to make the snow appear fresh for retakes. As expensive as it is to make a movie, it makes sense to use fake snow.

 

In the early twentieth century, filmmakers created fake snow with bleached cornflakes, salt, flour, cotton wadding, asbestos, or combinations of those materials as well as others. All posed problems either of realism or health and safety. Cornflakes crunched underfoot and were difficult to use once sound came into movies; salt was corrosive; flour congealed on exposure to moisture; cotton was a fire hazard, and its replacement, asbestos, was a health hazard. Filmmakers experimented with many materials, but it wasn’t until Frank Capra’s 1946 film It’s a Wonderful Life that they came upon a winning formula which was realistic and safe.

For that film produced by the studio RKO (Radio-Keith-Orpheum), special effects supervisor Russell Shearman helped create a mix of foamite – a fire extinguisher material – with sugar, water, and soap flakes. Mr. Shearman’s snow effects were so convincing that the Academy of Motion Picture Arts and Sciences gave him and his special effects department a Technical Achievement Award for their work on It’s a Wonderful Life. Watching this Christmas classic over 70 years later, after special effects have made huge advances in duplicating reality, and noticing how at the end of the movie the “snowflakes” on Jimmy Stewart’s shoulders take a long time to melt when he comes indoors to a warm reception from his family, friends, and neighbors, should not detract from anyone’s enjoyment of a great cinematic moment or the filmmakers’ expert creation of George Bailey’s (Stewart’s) snowy odyssey one long Christmas Eve in the fictional New York town of Bedford Falls (or its nightmare alternative, Pottersville). Movie magic at its best suspends the viewer in another world for a time, and on the few occasions when the artifice shows through, it’s charitable not to be too picky and to brush them off.

To Every Thing There Is a Season

 

People enjoy their home grown tomatoes so much more than store bought that they try to extend the growing season and stretch out the harvest. The primary limiting factor is the weather, and secondarily the genetics of tomato varieties. Tomato plants prefer temperatures between 55 and 95 degrees, and in most of the continental United States that means they do their best between June and September. Summer is their season. Genetically, full-sized tomato plants, as opposed to dwarf or cherry tomato varieties, fall into two groups – determinate or indeterminate. Determinate plants grow to a certain point, set fruit, and then are done for the season. Indeterminate plants continue growing and setting fruit throughout the season.

 

There are conditions and variables to all these factors, and they play an important part in seeing that, hard as a gardener may try, most of their tomatoes will ripen over a shorter period than plant information tags would have them believe. Plant tags give maturation dates for the tomato varieties they describe. They are only rough guides, not to be taken at face value! Too many gardeners believe the tags and think that by planting tomato varieties with as wide a spread of maturation dates as possible they will be ensured a lengthy harvest season. Not necessarily! The weather plays the biggest part in dictating when you will get ripe tomatoes and over how long a period. The next most important factor is whether the plant is determinate or indeterminate, since determinate varieties will almost always be the first to fruit and the first to stop bearing. The maturation date on the plant tag is the least reliable factor and is nearly useless.

Some gardeners think that by staggering the planting dates of their tomato plants they will stagger the harvest dates as well. Not necessarily! Again, the weather is the most important factor in how quickly or slowly your tomato plants grow. Plants started later in the spring will often catch up to ones planted earlier. Plants started too early in the spring will often sit there and do nothing until the weather warms up. You can’t fool Mother Nature!

The best way to lengthen the growing season, and therefore the harvest, is to make use of either a cold frame or a greenhouse, or both. Of the two, a greenhouse is the better option because it is ultimately more useful. A cold frame is useful mainly for starting plants, though it can also be used for low-growing vegetables and fruits like lettuce and strawberries. A greenhouse should be tall enough for fully grown tomato plants, even when they are in raised beds. A greenhouse is not a hothouse. A hothouse is, of course, heated. That would be stepping up another level in expense and trouble, which for a home gardener with a ten by twelve foot greenhouse would make every tomato unnecessarily expensive. No, a simple and inexpensive home greenhouse is primarily useful for extending the growing season from summer into spring at the front end, and autumn at the back end.

Roger Cook of This Old House helped this Mississippi homeowner build an inexpensive backyard greenhouse. At the end, Mr. Cook tells the homeowner he should be able to grow vegetables year round in the greenhouse. Since the greenhouse will be unheated, year round use would be possible in Mississippi, most of which is in winter hardiness zone 8a. Use in your location may be limited to three seasons.

There are home greenhouse kits on the market, and a gardener could spend over 1,000 dollars for a nicely appointed one. The very cheap ones are not worth even their low price, and will cause you more trouble than they’re worth. The greenhouse depicted in the This Old House video here is a solid, utilitarian model that should cost less than 500 dollars. It won’t win any awards for looks, but that would probably present an obstacle only for homeowners association members. One suggestion to improve upon the construction method in the video would involve using weather stripping or batting between the plastic and the staples to distribute the force of the plastic against the staples, reducing the chances of the plastic tearing loose in the wind. 1/2 inch staples would hold everything well, and to reduce frustration a quality staple gun is a must. As with a tarpaulin or any other lightweight material used outdoors, the plastic needs to be stretched tight to lessen its movement in the wind. After all that work and expense, you can look forward to a longer tomato harvest season, and to tomatoes that don’t cost a small fortune. You may even save a few dollars over the long haul, though it might be a stretch to say you could pay off your mortgage early, the way Radiator Charlie of West Virginia did with his ‘Mortgage Lifter’ tomatoes back in the 1940s.

A 50 Percent Chance of Stupidity

 

Last week, upon returning from Europe and announcing that the United States would withdraw from the Paris Climate Accord, Supreme Leader was supposed to have remarked to his companions over lunch after yet another weekend round of golf, “They can’t even get the weather report right, so how come they think they can get that right?” He was conflating weather with climate, a common mistake for laymen, but an unfathomable lapse for someone who has the best science at his fingertips, if only he had an interest in tapping it.

Stupidity may not account entirely for Supreme Leader’s climate change denial, nor for that of his core supporters or other conservatives, for denial of climate change does appear to be a trait of conservatives. Cupidity plays a part, in that the fossil fuel industry, a primary contributer to global warming, does all it can to deny it and thereby preserve its profits, much like the tobacco industry fought against cancer research. Until a recent study showed otherwise, people may have thought ignorance of the facts determined the stance of deniers. The study showed instead that deniers had as much access to the facts as anyone else, but they make the facts fit their predispositions on the issue, a trick which they can accomplish more easily with a long term problem like climate change. The effects of climate change are unfolding over a period expected to last well over a lifetime, into the lives of children and grandchildren, unlike the effects of smoking, which could be felt within a single lifetime.

Biloxi Blues, a 1988 film adapted by Neil Simon from his play, and directed by Mike Nichols, is a semi-autobiographical reminiscence of Simon’s Army days during World War II. In this scene, Christopher Walken as the drill sergeant uses the recruit played by Matthew Broderick to make a point to the platoon that they are all in this together, and an action or failure to act by any one of them affects them all. Warning: foul language.

The problem comes with the understanding that a flexible view of the facts does not change the facts, it only delays grappling with the inevitable. We may tell ourselves that the Chinese have perpetrated global warming as a hoax in order to subvert America’s competitive advantage, but that doesn’t alter the fact that it’s getting hotter, and that Americans are contributing more than their fair share to the problem while contributing less than their fair share to the solution. If we like, we may puff away like chimneys in order to keep pace with the Chinese, and then we can all collapse together, wheezing and clutching our chests, our insides poisoned.


That is not an entirely accurate analogy for the effects of climate change, however, which are longer term and more widespread than one individual’s smoking habit. And that is what makes it hard for some people to acknowledge, making it a failure of imagination. If they won’t accept on their own account that it’s getting hotter now, maybe they will accept that unless they pitch in to help solve the problem, or at least stop obstructing progress, then their children and grandchildren will feel the heat to a degree that there’s no denying. Until climate change deniers reach that acceptance, everyone else has to do what they can to stall global warming without any further delay. If the Ignoramus-in-Chief won’t lead on the issue, then it’s up to everyone else, starting with the states, to act on it and steer around the obstacles.

Titanic iceberg
The iceberg suspected of having sunk the RMS Titanic. This iceberg was photographed by the chief steward of the liner Prinz Adalbert on the morning of April 15, 1912, just a few miles south of where the Titanic went down. The steward hadn’t yet heard about the Titanic. What caught his attention was the smear of red paint along the base of the berg, an indication it had collided with a ship sometime in the previous twelve hours. This photo and information was taken from Unsinkable: The Full Story of RMS Titanic, written by Daniel Allen Butler, Stackpole Books 1998. Climate change deniers see an iceberg and say there is no global warming because there is still ice; others see an iceberg floating free in the shipping lanes and say “Watch out!” The crew of the Titanic, of course, didn’t see the iceberg at all.

 

Sowing Doubt for Fun and Profit

 

The first frost of fall was late this year across much of the U.S., in some places by one to three weeks, depending on the source of average frost date information. People who spend a lot of time outdoors tend to notice this, and also that a trend has developed of fall frosts arriving later and the last frost of spring coming earlier. Even people who pay attention to climate only sporadically may have noted the muted fall colors of the trees this year in parts of the eastern U.S., a result of extended warm weather and drought.

The growing season has increased over the last forty years or so, but that is not necessarily a good thing considering that short-lived creatures, such as insects, adapt more readily to swift changes than longer-lived plants and vertebrate creatures. Forty years is swift in the long view of climate. The short view is called weather, or weather events. Adding up weather events over forty years plots a trend in the climate. Unfortunately for the sake of rational discussion, too many people fail to make the distinction between weather and climate.

 

Not everyone agrees that the climate is getting warmer, or that if it is then humans are the cause of it. Some of those climate change deniers are motivated by their religious beliefs, others by a suspicion of government regulators, and still others are unmoved by the weight of scientific evidence, citing doubt about the conclusions. Who has sown that doubt? As always, we are well advised to follow the money. It comes as no surprise then that Big Oil, following the example set by Big Tobacco with regard to the link between burning their products and cancer, has worked to sow doubt about how the burning of fossil fuels contributes greenhouse gases to the atmosphere and causes a warming climate. Where there is doubt, they know, effective action against them can be hamstrung, and profits will continue to roll in until we all burn up from second hand smoke on a global scale.

Again following the money, the insurance industry is coming around to the reality of global warming and the increase in expensive weather events it is causing. The insurance industry, conservative gamblers that they are, are most interested in the economic facts they can pin down so as to minimize risk and maximize profit. They are not swayed by emotional appeals to religious or political views, but only by appeals to their bottom line. Another group whose costs are affected by the results of global warming are states and municipalities. As seas rise and severe weather events increase, causing unprecedented flooding, these entities have to pay for infrastructure improvements and higher insurance premiums.

 

States’ attorneys general are beginning to go after the fossil fuel industry to recoup costs, much as they did to the tobacco industry in the 1990s. It will be an even more protracted fight in this case because of the gargantuan amounts of money the fossil fuel giants can bring to bear; not everyone smoked in years past, after all, but today practically everyone uses gas, electricity, natural gas, plastics, and the list of products goes on. Some of these products can be replaced by use of renewable resources like wind and solar, but ultimately, like the reduction in use of tobacco products due to increasing social opprobrium, the steps for overcoming reliance on fossil fuel products and thereby breaking the economic stranglehold of Big Oil need to be taken by consumers, and that will require some wholesale changes in lifestyle, especially in the industrialized nations.
