Mitch caused over 9,000 deaths. 1 Source: Unisys 2) Vulnerability to Hurricanes Vulnerability is the susceptibility to physical or emotional injury or attack. “Disasters occur when hazards meet vulnerability". A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. Some factors influencing vulnerability: – Social – Physical 2 Source: Wikipedia Social aspects of vulnerability Awareness/Preparedness 1900 Galevston Hurricane – The Galveston Hurricane of 1900 is to date the deadliest natural disaster ever to strike the United States: estimated 8,000 fatalities. – Large death toll may be attributed to lack of awareness that the storm was coming 2 Source: Wikipedia Social aspects of vulnerability Miami Beach 1926 Wendler Collection Miami Beach 2006 Joel Gratz © 2006 2 50000 52000 54000 56000 58000 60000 62000 64000 66000 68000 1980 1991 2000 2010 2020 Projected Bermuda Population Growth Our own poulation density well exceeds 1000 people per km 2 Only forecast to get higher… 50000 52000 54000 56000 58000 60000 62000 64000 66000 68000 1980 1991 2000 2010 2020 2 Source: Government of Bermuda Dept. of Statistics Physical aspects of vulnerability Geography Hurricane Katrina, 2005 – City of New Orleans lies largely below sea level 2 Source: FEMA Events themselves drive vulnerability 2 Intensity: Andrew 1992 Mitch 1998 Fabian 2003 Frequency: Combinations of factors can maximize vulnerability 1970 Bhola Cyclone: Deadliest known tropical cyclone of all time – A powerful cyclone that hit Bangladesh on November 13, 1970 killed 500,000 people from storm surge, high winds, and flooding. 2005 Hurricane Katrina Factors: – Lack of Awareness &/or Preparedness – Geography – Population – Intensity 2 3) Global Warming and Hurricanes 3 Source: UEA NHC Best Track Storm Database 3 Source: Landsea, 2006 Bermuda Best Track Storms Historically Bermuda is affected on average ~1 every 2 years (not necessarily direct hits) 0 1 2 3 4 1895 1900 1905 1910 1915 1920 1925 1930 1935 1940 1945 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 More recently… 3 Source: BWS Global Warming & Increase in Hurricane Frequency? 0 1 2 3 4 1895 1900 1905 1910 1915 1920 1925 1930 1935 1940 1945 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 Two camps – fierce debate.

Vulnerability to Hurricanes is compounded by social and physical aspects like – Geography, – Population and – Awareness, – in addition to the frequency and intensity of the events themselves. Recap The effects of global warming on hurricanes in the Atlantic are not as clear as they might appear at first. Unreliable database before: –Satellites and Radar –Aircraft reconnaissance –Weather Balloons Water is the biggest cause of fatalities in hurricanes, not direct wind strength. Hurricane force winds don't always come from what we classically think of as hurricanes. Any Questions? Dr. Mark Guishard Director, Bermuda Weather Service
You Don't Know Jack (Brava Contemporary Romance) - PDF
نویسندگان: خلاصه: Jamie Peters no longer believes in true love. True idiots, true scumbags, true moochers - these she believes in wholeheartedly, and she's got the checkered dating history to prove it. So she's more than a little skeptical when her cross-dressing psychic tells her she's about to meet her soul mate - during an accident. Yeah, sounds about right. And then it happens. A kinght in shining armor steps between her and a mugger on a subway platform. Just a regular, honest, upright Jack. The kind they don't make anymore...Jonathon Davidson doesn't believe in destiny - or lying to beautiful women as a rule. But now that Jamie thinks he's just an ordinary guy, how can he possibly tell her that he's really, her roommate's brother, a millionaire to boot, and the jerk who's investigating her application to his grandfather's charitable trust because she may be involved in something illegal? Yeah, rhetorical question. He can't. Not until he knows what's going on. Besides, it would require being able to resist Jamie's luscious curves long enough to say, 'Hi, my name is Big Liar. Let's get naked'. Sometimes, destiny sucks...
The Better to Eat You With: Fear in the Animal World - PDF
نویسندگان: خلاصه: At dawn on a brutally cold January morning, Joel Berger crouched in the icy grandeur of the Teton Range. It had been three years since wolves were reintroduced to Yellowstone after a sixty-year absence, and members of a wolf pack were approaching a herd of elk. To Berger’s utter shock, the elk ignored the wolves as they went in for the kill. The brutal attack that followed—swift and bloody—led Berger to hypothesize that after only six decades, the elk had forgotten to fear a species that had survived by eating them for hundreds of millennia. Berger’s fieldwork that frigid day raised important questions that would require years of travel and research to answer: Can naive animals avoid extinction when they encounter reintroduced carnivores? To what extent is fear culturally transmitted? And how can a better understanding of current predator-prey behavior help demystify past extinctions and inform future conservation?The Better to Eat You With is the chronicle of Berger’s search for answers. From Yellowstone’s elk and wolves to rhinos living with African lions and moose coexisting with tigers and bears in Asia, Berger tracks cultures of fear in animals across continents and climates, engaging readers with a stimulating combination of natural history, personal experience, and conservation. Whether battling bureaucracy in the statehouse or fighting subzero wind chills in the field, Berger puts himself in the middle of the action. The Better to Eat You With invites readers to join him there. The thrilling tales he tells reveal a great deal not only about survival in the animal kingdom but also the process of doing science in foreboding conditions and hostile environments. (20081107)
Everything You Know About English Is Wrong - PDF
نویسندگان: خلاصه: Never trust a bookstore employee who, when asked where to find etymology and word books, leads you to the word-search puzzle rack. In the true story that prompted this advice, I stared at the pulp- paper acrostics and cryptograms and crosswords. Though a bit flummoxed, I realized that I should forgive this earnest associate. After all, English itself is, in a broad sense, a word puzzle, and like both those puzzles and the queries of where the etymology section of the bookstore is, sometimes people try hard yet come up with wrong answers. Our understanding of English—its history, its rules, its use—is often misconceived, misguided, misinformed, or based on some lie someone told us, probably via email, cuz it made a good story. Yet, what a wondrous language. Puzzle me this language always, despite its inherent confounderies.

Fight Back and Win: My Thirty-year Fight Against Injustice--and How You Can Win Your Own Battles - Original PDF
نویسندگان: خلاصه: The World-renowned women's rights attorney and civil rights advocate shares empowering life lessons learned from her career fighting on the front lines for victims' rights Fearless lawyer, feminist, activist, television and radio commentator, warrior, advocate, and winner -- Gloria Allred is all of these things and more. Voted by her peers as one of the best lawyers in America, and described by Time as ''one of the nation's most effective advocates of family rights and feminist causes,'' Allred has devoted her career to fighting for civil rights across boundaries of gender, race, age, sexual orientation, and social class. She has taken on countless institutions to promote equality, including the Boy Scouts, the Friars Club, and the United States Senate, often drawing from her creativity and wit to achieve results. And as the attorney for numerous high-profile clients -- she has represented Nicole Brown Simpson's family, actress Hunter Tylo, and Amber Frey, Scott Peterson's girlfriend -- Allred has helped victims assert and protect their rights. Throughout her extraordinary memoir, in such chapters as ''To Conquer, You Must First Conquer Yourself'' and ''Don't Be Victimized Twice,'' Allred offers colorful -- sometimes shocking -- examples of self-empowerment from her personal and professional life. Presenting nearly fifty of her most memorable cases, she takes us deep inside the justice system to show how it's possible to win, even in the face of staggering odds. Allred opens our eyes not only to the significant positive strides we've made in recent decades, but more important, to how much further we still have to go to empower all members of society -- especially women, minorities, and others who are deprived of their rights. Fight Back and Win is a powerful testament to Gloria Allred's trailblazing career and the battles she has fought alongside countless brave individuals to win justice for us all.
