Pandemic Survival Guide
The correlation between pandemics and drops in atmospheric CO2 concentrations was suggestive, but what was the connection How could plague and other diseases cause the drops in CO2 Part of the answer to these questions comes from historical records summarized in chapter 13. These records document abandonment of farms and farm villages on a massive scale during and after all three major pandemics. In the wake of the European plagues, abandoned farms are described as having gone to waste or ruin. Those words bring to mind doors flapping in the breeze, roofs sagging and collapsing in upon houses and barns, and wild vines creeping up and strangling rotting fences. But nature was doing much more than that. Nature was busy turning pastures and croplands back into forest, and remarkably quickly. Here, then, is a possible mechanism to pull CO2 out of the atmosphere in a few decades widespread reforestation as a result of pandemic mortality. Imagine the following scenario. During the years...
The H5N1 virus has become established in bird populations of Southeast Asia and it has probably already reached the Arctic through migratory water birds. Avian flu virus can last indefinitely at a temperature dozens of degrees below freezing, as it is found in the northern most areas that migratory birds frequent. Influenza A viruses can survive over 30 days at 0 C (over 1 month at freezing temperature). Recently Scott Rogers from Bowling Green State University in Ohio and his colleagues found the influenza A virus genes in ice and water from high-latitude lakes that are visited by large numbers of migratory birds (Rogers et al., 2006). It shows that there is potential for a human virus to survive the freezing process. Imagine if older, more vicious strains, such as the virus responsible for the Spanish flu pandemic, which killed somewhere between 20 and 40 million people in 1918-1919, were to re-emerge. So if these viruses have been huddled in the ice for thousands of years, how did...

The worst epidemics have killed 30 million to 100 million people, even if one considers the bubonic plague pandemic in fourteenth-century Eurasia (and possibly Africa) as a single event (a pandemic is an especially widespread epidemic, often global in scope). The most recent epidemic on such a scale, the influenza that raged from 1918 to 1919, killed perhaps 40 million (about 2 percent of the global population). The ongoing AIDS pandemic has so far killed 25 million to 30 million, about 0.5 percent of the current world population.4 Such pandemics have been mercifully rare, but past epidemics that affected regions or single cities were not, and they routinely killed 5 to 10 percent or even more of the affected population.

Even though natural shocks regularly took a significant demographic toll, it is worth emphasizing that the great majority of floods, drought, epidemics, and so on had only local or regional effects and took the lives of small numbers of people. In the distant past, because the human population was small, the numbers of victims were small. It has remained true over the past fifty years partly because of luck (nothing really bad has come up since the influenza pandemic of 1918 to 1919) and partly because public health systems, disaster management systems, and so forth have grown remarkably effective. The worst historical era for demographic losses from natural shocks came between 1300 and 1920. Although the costs from nature's shocks rose rapidly and the shocks could have devastating local effects for a decade or more none in modern history, not even the 1918-to-1919 influenza, had durable economic consequences that changed the basic fortunes of nations. One could not make that claim...

This may interpret the lack of economic phosphate deposits in the Paleogene of Egypt as well as the same interval of the surrounding areas of the Middle East and North Africa. In general, it seems that the studied Paracosta species is pandemic and tends to adapt to changes in depth and saturation of CaCO3 in the water through the ability to exhibit polymorphism during its life cycle. On the other hand, the ancestor of this species (Paracosta mokattamensis praemokattamensis Bassiouni, according to Bassiouni and Elewa 1999) is possibly an endemic species and was recorded by Bassiouni (1969a) from the Eocene of Jordan. Nevertheless, auxiliary studies of the geographical distribution of the latter species is needed to demonstrate its routes of migration.
Human immunodeficiency virus (HIV) and or acquired immunodeficiency syndrome (AIDS) pandemic, particularly in Southern Africa, attacking agriculture through mass deaths of prime-age adults, which diverts labour resources to caring, erodes household assets, disrupts intergenerational transmission of agricultural knowledge, and reduces the capacity of agricultural service providers
There are cities that were founded because they were just above the mosquito line. Nairobi is one. Harare is another. There are plenty of others. Now the mosquitoes with warming are climbing to the higher altitudes. There are a lot of vectors for infectious diseases that are worrisome to us that are also expanding their ranges, not only mosquitoes but all of these others as well. And we've had 30 so-called new diseases that have emerged just in the last quarter-century. And a lot of them like SARS severe acute respiratory syndrome have caused tremendous problems. The resistant forms of tuberculosis. There are others. And there's been a reemergence of some diseases that were once under control. The avian flu, of course, is quite a serious matter as you know. West Nile virus. It came to the eastern shore of Maryland in 1999. Two years later it was across the Mississippi. And two years after that it had spread across the continent. But these are very troubling signs.
The relatively poor resolution of PMRs has been overcome for one type of active microwave sensor by using the motion of the satellite to simulate an antenna much larger than can actually be flown in space. To achieve this, both the phase and the amplitude of the radar signal are recorded. The sensor in question is known as a synthetic aperture radar (SAR) and has, since the launch of the first European Remote Sensing satellite (ERS-1) in 1991, become an invaluable tool in studies of both land and sea ice. The typical resolution of current spaceborne SARs is ca. 25 m. Table 73.3 lists recent and planned satellite SAR missions. Although SARs offer good spatial resolution, their use for certain glacio-logical applications is limited by the fact that the current suite of sensors are single frequency. Thus discrimination of surface characteristics can be hampered because a multispectral interpretation of the signal is not possible. Differentiation between sea ice
The signatures of younger and thinner ice types, however, are more complex and less easy to identify uniquely. Typically, therefore, only the two crude categories, FY and MY, can be readily identified in classification procedures. Ice-type data sets are being produced routinely from the SAR onboard RADARSAT (and hopefully its successor, RADARSAT-2) (Kwok, 1998). Because of the higher resolution of SARs (ca. 25 m), the assumption of a mixture of ice types within a pixel is not necessary.
Approaches have often proved more valuable. As mentioned earlier, microwave sensors are particularly useful in the polar regions owing to their all-weather, day night functioning. The two instruments that have been used most successfully for deriving topography are radar altimeters and synthetic aperture radars (SARs).
In the case of severe climate change, projected massive nonlinear events in the global environment give rise to massive nonlinear societal events. In this scenario, nations around the world will be overwhelmed by the scale of change and by pernicious challenges, such as pandemic disease and water and food shortages. The internal cohesion of nations will be under great stress, including in the United States, owing to a dramatic rise in migration, changes in agricultural patterns and water availability, and the pulling away of wealthier members of society from the rest of the population.

The tendency for increased spoilage is problematic down the production chain. While it is difficult to blame directly on ENSO, there is a tendency for a sharp increase in gastrointestinal problems during the warm weather, again, due in part to a lack of refrigeration in many parts of the country, and the accelerated growth of bacteria because of adverse climatic conditions. An extreme example of the apparent linkage between ENSO and human health is the Pan-American cholera pandemic that began off the coast of northern Peru and spread across the continent in 1991. Facilitated by the 1992 ENSO, cholera destroyed the Peruvian market for artisanal fish and rapidly spread throughout South America. (Epstein, 1993). Vibrio cholera, which has been isolated from phyto- and zooplankton, is directly influenced by changes in water temperature and chemistry.
The fact that SARs record the phase of the signal has allowed for the possibility of combining images taken at different times and or locations to produce interference patterns caused by differences in phase in the two images. This is known as interfero-metric SAR or InSAR and its use has resulted in some remarkable results. Repeat pass interferometry is where pairs of images are combined that have been taken at different times (and from slightly different positions along an orbit) and began to be developed for glaciological applications after the launch of ERS-1 in 1991. Single pass interferometry (as exemplified by the shuttle radar topography mission, SRTM) is where two images are recorded at the same time but from different positions. Differences in path length of a fraction of a wavelength can be measured from the phase offset between the two images allowing, for example, millimetric displacements to be observed. The interference pattern is a function of (i) the topography, (ii)...
The misery of living in a tropical climate as well as the ever-present threat of contracting malaria are the two aspects of climate change through heating that don't get much press. Yet as the tropics begin to spread north and south from the low latitudes of Earth, scourges of the tropics will be coming too. We are returning to a planet with worldwide malaria foremost, but there're more Ebola, elephantiasis, schistosomiasis, leprosy, rampant intestinal parasites, poisonous spiders and centipedes, new and vicious kinds of ants all will follow the heat once the barriers of coolness are overcome.
What will be the difference between severity level 6 and severity level 7 I wish I knew. Conceivably, not a lot - perhaps level 7 is just a bit worse than 6 but not significantly different. On the other hand, level 7 could be dramatically worse if some threshold is passed during the transition between these two levels that would not ever have been passed if the planetary deterioration had stopped at level 6. Perhaps at level 7 species extinctions begin to cascade, perhaps the global human pandemic comes, perhaps the Younger-Dryas-like reversal from rapid warming to rapid cooling is triggered, and so on. Obviously these levels are merely an illustrative abstraction, and I do not know exactly what they might mean. Yet the point is clear to delay is to play with fire (and ice). At some point things will probably become truly nasty. Maybe the nasty one is level 13, and the difference between levels 6 and 7 is unremarkable. Maybe the nasty one is level 3, and the passage beyond 6 to 7 will...

The SAR systems offer perhaps the best opportunity to measure soil moisture routinely over the next few years. Currently, the European Resources Satellite (ERS-1) C-band and Japan Environmental Resources Satellite (JERS-1) L-band SARs and the Canadian RADARSAT (also C-band) are operational. Although it is believed that an L-band system would be optimum for soil moisture, the preliminary results from the ERS-1 C-band radar demonstrate its capability as a soil moisture instrument. One main drawback to the existing SAR systems is that there are no existing algorithms for the routine determination of soil moisture from single-frequency, single-polarization radars. A second limitation comes from their long period between repeat passes for the most part it is 35 to 46 days, although the RADARSAT has 3-day capability for much of the globe in a SCANSAR (wide swath, 500 km) mode.

Continuing high spatial resolution data from the Landsat and SPOT satellites, passive microwave data from the special sensor microwave imager (SSM I) and continuing meteorological satellite coverage from the NOAA, GOES, GMS, and Meteosat series all mean that the remotely sensed techniques can continue to be employed and expanded upon. New sensors, particularly in the microwave region, promise great potential for hydrologie applications. There are several satellites, such as ERS-1 2 launched by the European Space Agency, the J-ERS-1 launched by the Japanese, and RADARSAT launched by the Canadians that will provide useful data for hydrologists. All carry single-polarization, single-frequency SARs. An additional satellite being planned that will have considerable hydrologie interest is the Tropical Rainfall Measurement Mission (TRMM) (Simpson et al., 1988).
The SAR for typical municipal effluents seldom exceeds a value of 5 to 8, so it should not be a problem with most soils in any climate. Soils with up to 15 clay can tolerate a SAR of 10 or less, while soils with little clay or with nonswelling clays can accept SARs up to about 20. Industrial wastewaters can have a high SAR, and periodic soil treatment with gypsum or some other inexpensive source of calcium may be necessary to reduce clay swelling. Soil salinity is managed by adding an excess of water above that required for crop growth to leach the salts from the soil profile. A rule of thumb for total water required to prevent salt buildup in arid climates is to apply the crop needs plus about 10 (Pettygrove and Asano, 1985). A report by the USEPA (1984) provides further details.
Diseases affect homeostasis, which is the feedback that maintains a living organism's body function within limits essential for the body to continue functioning properly, despite external and internal stresses that would move the system away from balance. Diseases that exist in a population for a long time, where they are maintained at a low level, are called endemic. An epidemic occurs when there is a marked increase in the incidence of disease within a region. When an epidemic spreads around the world it becomes a pandemic. For example, the 1918 pandemic is believed to have been related to 30 million deaths. Climate change is expected to increase the spread of disease, especially biologically-transmitted pathogens.
