Lesson from the past for surviving climate change
May 28, 2009Research examines how past communities coped with climate change
Research led by the University of Leicester suggests people today and in future generations should look to the past in order to mitigate the worst effects of climate change.
The dangers of rising sea levels, crop failures and extreme weather were all faced by our ancestors who learnt to adapt and survive in the face of climate change.
Dr Jago Cooper, of the School of Archaeology and Ancient History at the University of Leicester, has been studying the archaeology of climate change in the Caribbean as part of a Leverhulme Early Career Fellowship.
The international study involves researchers from Britain, Cuba and Canada. Dr Cooper said: "Populations in the Caribbean, from 5000 BC to AD 1492, successfully lived through a 5m rise in relative sea levels, marked variation in annual rainfall and periodic intensification of hurricane activity.
"This research examines the archaeological lessons that can inform current responses to the impacts of climate change in the Caribbean. I have examined the relationship between long and short-term effects of climate change and past human engagement with the geographical, ecological and meteorological consequences."
"A key focus of the research has been to investigate past mitigation of the impacts of climate change through the analysis of changes in settlement structures, food procurement strategies and household architecture."
The study is part of a long term project, begun in 1997, that includes a wide-ranging study of archaeological and paleoenvironmental data. Key to the research has been to understand how the past can inform the future.
Said Dr Cooper: "We have acquired archaeological information that has then been closely correlated in space and time with the long and short-term impacts of climate change. It has then been possible to evaluate the relative advantages and disadvantages of past cultural practices in the face of environmental change and establish lessons that will contribute to contemporary mitigation strategies. "
Following the end of the last Ice Age, the people of the Caribbean have had to cope with a relative sea level rise of 5m over 5,000 years. Hurricanes led to storm surges that reached inland more than ever. Groundwater became contaminated with salt and the land was waterlogged.
But the researchers found that far from abandoning life by the coast and moving further inland, people continued to live by the shore- and even built houses on stilts over a lagoon.
An ancient site in Cuba, Los Buchillones, that is currently out to sea "represents a way of living that capitalises on hundreds or even thousands of years of experience."
Dr Cooper warns that modern settlements are more at risk of flooding because they are constructed in more vulnerable places. In fact, indigenous settlement locations over water could make homes less at risk of flooding as floodwater could flow beneath the homes and inland rather than pour into the houses.
This ongoing research has looked at past mitigation strategies, assessed how pre-Colombian settlements were located close to cave complexes that acted as refuges during times of past hurricanes, how the architecture of homes were constructed from local resources allowing people to rebuild them easily upon their return. It also reveals how local populations diversified their food production to mitigate against resource scarcity.

ndia may rank only a distant fourth in terms of carbon dioxide emissions, behind China, the United States and Russia, but its rapid economic growth rate coupled with aging and inefficient energy infrastructure suggest dire environmental consequences if "business as usual" continues.
Experts: Failure to focus on farming will undermine global climate agreement and increase hunger
Alarmed by a substantial oversight in the global climate talks leading up to the United Nations Climate Change Conference in Copenhagen next month, more than 60 of the world's most prominent agricultural scientists and leaders underscored how the almost total absence of agriculture in the agreement could lead to widespread famine and food shortages in the years ahead.

What We Know About Climate Change (Boston Review Books) by Kerry Emanuel (Author), Judith A. Layzer (Afterword), William R. Moomaw (Afterword) The vast majority of scientists agree that human activity has significantly increased greenhouse gases in the atmosphere—most dramatically since the 1970s. In February 2007 the Intergovernmental Panel on Climate Change found that global warming is "unequivocal" and that human-produced carbon dioxide and other greenhouse gases are chiefly to blame, to a certainty of more than 90 percent. Yet global warming skeptics and ill-informed elected officials continue to dismiss this broad scientific consensus. In What We Know About Climate Change, MIT atmospheric scientist Kerry Emanuel outlines the basic science of global warming and how the current consensus has emerged. Although it is impossible to predict exactly when the most dramatic effects of global warming will be felt, he argues, we can... |

The Ethics of Climate Change: Right and Wrong in a Warming World (Think Now) by James Garvey (Author) The debate about the existence of climate change seems finally at an end. We now have to decide what to do about it. Here, James Garvey argues that the ultimate rationale for action on climate change cannot be simply economic, political, scientific or social, though no doubt our decisions should be informed by such things. Instead, climate change is largely a moral problem. What we should do about it depends on what matters to us and what we think is right.This book is an introduction to the ethics of climate change. It considers a little climate science and a lot of moral philosophy, ultimately finding a way into the many possible positions associated with climate change. It is also a call for action, for doing something about the moral demands placed on both governments and individuals... |

Climate Confusion: How Global Warming Hysteria Leads to Bad Science, Pandering Politicians and Misguided Policies that Hurt the Poor by Roy Spencer (Author) The current frenzy over global warming has galvanized the public and cost taxpayers billons of dollars in federal expenditures for climate research. It has spawned Hollywood blockbusters and inspired major political movements. It has given a higher calling to celebrities and built a lucrative industry for scores of eager scientists. In short, ending climate change has become a national crusade. And yet, despite this dominant and sprawling campaign, the facts behind global warming remain as confounding as ever. In Climate Confusion, distinguished climatologist Dr. Roy Spencer observes that our obsession with global warming has only clouded the issue. Forsaking blindingly technical statistics and doomsday scenarios, Dr. Spencer explains in simple terms how the climate system... |
