“In similar climate-related conflicts, consider the Blanket War of 7298-7299, which took place on Calabar (Ymar’s Chasm). Calabar was a divided world going through late industrial-period development, whose primary energy source for several centuries had been the combustion of the large deposits of fossil carbon found beneath the icebound northern continent. The consequent release of carbon dioxide into the atmosphere in quantities sufficient to measurably alter its composition was, via the glass-garden effect, responsible for an increase in Calabar’s global temperature and the various consequences thereof, which in turn required measures to be taken for the smooth continuance of civilization.

“The initial measure chosen by the Coordinated Polities of Calabar – an international organization charged with peace maintenance and the promotion of international cooperation – was the use of a sunshade to reduce insolation, intended as a temporary measure to buy time for alternate energy sources to be deployed.

“In deference to Calabar’s limited domestic space capabilities, which would have made both maintenance and local control of a sunshade difficult, the Coordinated Polities (or, rather, Tsakalakia, the nation to which the task had been delegated by the CP) elected to license the means to deploy a shroud blanket. Using multiple projector towers for continuous deployment and replenishment, this maintains a haze of metamaterial ‘flakes’ in the upper atmosphere, deflecting incoming light and heat from above while permitting them to escape from below.

“Unfortunately, this did not take into account Throtal, Tsakalakia’s neighbor to the north, which would lose the increased arable land area and a longer growing season it had been enjoying in recent years and thus wished to maintain the status quo. The Throtalic Parliament, unable to extract an agreement permitting the planet’s current heated state to persist or sufficient compensation from the Coordinated Polities for these losses, had become afflicted by an unfortunate species of ‘war fever’, and in the winter of 7298, launched an invasion of Tsakalakia with the intent to seize and shut down the projector towers until accomodations could be reached.

“To their dismay, the invasion bogged down almost immediately. While the surprise attack did permit Throtal to seize two of the eleven projector towers, superior Tsakalakian forces were able to hold the line and push back those of Throtal. With additional forces from other polities being shipped to Tsakalakia to enforce the authority of the Coordinated Polities, Throtal elected in the early part of 7299 to make a demonstration tactical nuclear strike, using low-yield warheads, against six of the remaining projector towers.

“This decision proved disastrous. While it did eliminate the ability of those sites to deploy the shroud blanket, as planned, the stocks of metamaterial flakes held at those sites – sufficient for several years’ normal operation – were not destroyed by the nuclear detonation, but dispersed by it. Initially, this unplanned, unmonitored dispersal brought a low-altitude permanent night to north-central Tsakalakia and, as the plume spread with the prevailing winds, to the western two-thirds of Throtal, with an accompanying severe drop in temperature which destroyed crop yields and caused surface icing beneath the plume.

“As the months passed, however, more serious consequences became visible. As the plume dispersed and the flakes within it ascended over time closer to their proper deployment altitude, it eventually settled into an active shroud blanket substantially thicker than intended, causing a dramatic drop in global temperature with serious consequences for agriculture and logistics for every polity on Calabar – and Throtal in particular, which became almost entirely tundral. Fortunately for the planet, although not the planetary budget, they retained five operational projector towers with which to disperse first nanophages, and later a glass-garden blanket to bring global temperature back up to the desirable range.

“The obvious lesson of the Blanket War is to understand how what you’re shooting at will react before you shoot at it. The less obvious, I leave to you.”

The Heat of Battle

“Next in our study of how climatic and ecological events affect military and logistic strategy, we will be studying the Cold War.

“Taking place on Qern (Aris Delphi), in the years 7199-7223, the Cold War was directly caused by such an event. Following the asteroid impact of 7197, the ensuing particle winter caused catastrophic temperature drops with associated crop loss, glaciation, power grid failures, thermal infrastructure inadequacy, and so forth all across Qern’s southern hemisphere.

“In response to this, the southern powers – initially independently, but later united as the Austral Alliance – waged war against first the tropics, and later the more southerly regions of the less-affected northern hemisphere – in an attempt to seize territory that was both warm enough to allow food production and relatively survivable conditions, and which was not in imminent danger of being buried under a mile-high ice sheet.

“At first, the war was inconclusive and poorly prosecuted on both sides, with the shattering of the northern powers’ economy by the impact – immortalized forever in the term Qern cost center – and the increasing failure rate of the southern powers’ equipment as the temperature fell, not to mention the disruption of both sides’ command and logistic chains by the increasingly harsh weather.

“However, with the ingenuity of desperation, the southern powers in particular devised a range of cold-adapted military technologies, including snowdrills, ice-boats, bergpiers, and more, as well as crude but serviceable adaptations to existing technologies compensating for thermal embrittlement, frost- and flood-damaged terrain, and the erosive, corrosive environment of a particle winter. It is these technologies, and the modifications they imposed on logistics and strategy in the latter period of the Cold War, that we shall be examining in these next four lectures…”
