In this interactive feature produced by ThinkTV, explore an alpine glacier to learn about melting, evaporation, sublimation, calving, and accumulation. Together these processes determine whether a glacier is growing or shrinking—scientists compare the annual accumulation of ice and snow to the annual loss of ice and snow to calculate any changes in the glacier’s mass balance. These measurements help scientists determine if a glacier is shrinking, and how the loss of mass may be related to climate change.

Today we’re going to talk about glaciers. These behemoth globs of compressed ice and snow moving across the land created fertile soils and physical features while also serving as frozen time capsules. They recorded both Earth’s climatic history over several million years and contain clues to its climatic future. By now we hope it’s become clear that the Earth is ever-changing, and glaciers have often been a crucial part of that change from the erratic boulders found in New York City’s Central Park to the beautiful spire of the Matterhorn in the Alps on the border of the Italy and Switzerland.

John Snow's single case study was not enough to convince the medical community that cholera was spread through the water, but he did not give up. He founded the Epidemiological Society of London in 1850, the first organization dedicated to studying not just cures for disease, but also their causes. And so when cholera returned in 1854, John Snow saw a chance to finally prove his theory and set about studying the patterns of disease. The disease appeared to strike randomly, both rich and poor, but he realized that in his district were two different water companies, one of which he theorized might be contaminated. Finding evidence proved more difficult than he anticipated: going to door to door, he was often met by people who didn't even know what water company supplied their building. He tracked down landlords and even developed a water test to help him identify which water source each house had, but before he had the time to compile and analyze his findings, another terrible outbreak struck in Broad Street.

John Snow raced to discover the causes of the cholera epidemic that swept Broad Street. He went door-to-door talking to the locals, then surveyed government records for extra clues. He began to craft a map of deaths, and drew the first Voronoi Diagram to assess the victims' proximity to the pump. All but 8 of the 84 victims were closer to the Broad Street Pump (and hence more likely to use it) than any other pump, and most of the remainder had daily commutes that took them past the pump. He also noticed that a local workhouse and a tavern were conspicuously cholera-free despite their proximity to the pump, and found that they had access to their own drinking supplies which unbeknownst to them had kept them safe. With his evidence in hand, he met with the local health commission and convinced them to deactivate the Broad Street Pump. But his theory was still not widely accepted, and after the epidemic passed everything returned to normal. At last, a local pastor named Henry Whitehead set out to debunk the wild theories about what had caused the epidemic in his parish. He doubted Snow's results, but as he investigated, he found more evidence that backed them up. His relationship with the neighborhood also meant he could get information Snow couldn't, and it was thus that he found Patient Zero: a baby who died two days before the epidemic, and whose mother had been throwing her dirty diapers in a cesspit under the house. The government investigated and found that the poorly-built cesspit had begun leaking into the Broad Street Pump's water supply, infecting all who drank from it with cholera passed along in the baby's diapers. It would take many years before John Snow's theory became an accepted fact, but his research paved the way for the modern medical field of epidemiology. (08:59)
