They've been hearing this same fear-mongering their entire lives and know it's bullshit;

Before 1970 The Arctic ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot…. Reports from fishermen, seal hunters and explorers, he declared, all point to a radical change in climate conditions and hitherto unheard-of temperatures in the Arctic zone… Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared. Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts, which have never before ventured so far north, are being encountered in the old seal fishing grounds. -Washington Post 11/2/1922 The discoveries of changes in the sun’s heat and southward advance of glaciers in recent years have given rise to the conjectures of the possible advent of a new ice age -Time Magazine 9/10/1923 America in longest warm spell since 1776; temperature line records a 25 year rise – New York Times 3/27/1933 A mysterious warming of the climate is slowly manifesting itself in the Arctic, engendering a "serious international problem," -New York Times – May 30, 1947 Greenland’s polar climate has moderated so consistently that communities of hunters have evolved into fishing villages. Sea mammals, vanishing from the west coast, have been replaced by codfish and other fish species in the area’s southern waters. -New York Times August 29, 1954 After a week of discussions on the causes of climate change, an assembly of specialists from several continents seems to have reached unanimous agreement on only one point: it is getting colder. -New York Times – January 30, 1961 Like an outrigger canoe riding before a huge comber, the earth with its inhabitants is caught on the downslope of an immense climatic wave that is plunging us toward another Ice Age. -Los Angeles Times December 23, 1962 The battle to feed humanity is over. In the 1970s, the world will undergo famines. Hundreds of millions of people are going to starve to death in spite of any crash programs embarked upon now. – Paul Ehrlich – The Population Bomb (1968) It is now pretty clearly agreed that the CO2 content [in the atmosphere] will rise 25% by 2000. This could increase the average temperature near the earth’s surface by 7 degrees Fahrenheit. This in turn could raise the level of the sea by 10 feet. Goodbye New York. Goodbye Washington, for that matter. -Presidential adviser Daniel Moynihan, 1969 (later Sen. [D] from New York 1976-2000) From the 70s

"Scientists have solid experimental and theoretical evidence to support…the following predictions: In a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half…." -Life Magazine, January 1970 "If present trends continue, the world will be … eleven degrees colder by the year 2000. This is about twice what it would take to put us in an ice age." -Kenneth E.F. Watt in "Earth Day," 1970. "Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions….By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine." -Peter Gunter, professor, North Texas State University "Population will inevitably and completely outstrip whatever small increases in food supplies we make. The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years." -Paul Ehrlich, Stanford University biologist 1970 "By…[1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s." -Paul Ehrlich, Stanford University biologist 1970 In ten years all important animal life in the sea will be extinct. Large areas of coastline will have to be evacuated because of the stench of dead fish. -Paul Ehrlich, Earth Day (1970) "Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind." -George Wald, Harvard Biologist 1970 Because of increased dust, cloud cover and water vapor "…the planet will cool, the water vapor will fall and freeze, and a new Ice Age will be born," -Newsweek magazine, January 26, 1970. New Ice Age Coming—It’s Already Getting Colder. Some midsummer day, perhaps not too far in the future, a hard, killing frost will sweep down on the wheat fields of Saskatchewan, the Dakotas and the Russian steppes -Los Angles Times Oct 24, 1971 "By the year 2000 the United Kingdom will be simply a small group of impoverished islands, inhabited by some 70 million hungry people … If I were a gambler, I would take even money that England will not exist in the year 2000." -Paul Ehrlich, Speech at British Institute For Biology, September 1971 Arctic specialist Bernt Balchen says a general warming trend over the North Pole is melting the polar ice cap and may produce an ice-free Arctic Ocean by the year 2000. -Los Angles Times – May 16, 1972 From the 1980s

[In New York City by 2008] The West Side Highway [which runs along the Hudson River] will be under water. And there will be tape across the windows across the street because of high winds. And the same birds won’t be there. The trees in the median strip will change. There will be more police cars. Why? Well, you know what happens to crime when the heat goes up… Under the greenhouse effect, extreme weather increases. Depending on where you are in terms of the hydrological cycle, you get more of whatever you’re prone to get. New York can get droughts, the droughts can get more severe and you’ll have signs in restaurants saying "Water by request only." -James Hansen testimony before Congress in June 1988 U.N. OFFICIAL PREDICTS DISASTER SAYS GREENHOUSE EFFECT COULD WIPE SOME NATIONS OFF MAP – entire nations could be wiped off the face of the earth by rising sea levels if global warming is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of "eco-refugees," threatening political chaos, said Brown, director of the New York office of the U.N. Environment Program. He said governments have a 10-year window of opportunity to solve the greenhouse effect -Associated Press June 30, 1989 New York will probably be like Florida 15 years from now -St. Louis Post-Dispatch Sept. 17, 1989 Some predictions for the next decade (1990’s) are not difficult to make… Americans may see the ’80s migration to the Sun Belt reverse as a global warming trend rekindles interest in cooler climates. -Dallas Morning News December 5th 1989 "(By) 1995, the greenhouse effect would be desolating the heartlands of North America and Eurasia with horrific drought, causing crop failures and food riots… "(By 1996) The Platte River of Nebraska would be dry, while a continent-wide black blizzard of prairie topsoil will stop traffic on interstates, strip paint from houses and shut down computers… "The Mexican police will round up illegal American migrants surging into Mexico seeking work as field hands". -Michael Oppenheimer, "Dead Heat" 1990 Giant sand dunes may turn Plains to desert – Huge sand dunes extending east from Colorado’s Front Range may be on the verge of breaking through the thin topsoil, transforming America’s rolling High Plains into a desert, new research suggests. The giant sand dunes discovered in NASA satellite photos are expected to re- emerge over the next 20 to 50 years, depending on how fast average temperatures rise from the suspected "greenhouse effect," scientists believe. -Denver Post April 18, 1990 By 2000, British and American oil will have diminished to a trickle……Ozone depletion and global warming threaten food shortages, but the wealthy North will enjoy a temporary reprieve by buying up the produce of the South. Unrest among the hungry and the ensuing political instability, will be contained by the North’s greater military might. A bleak future indeed, but an inevitable one unless we change the way we live…..At present rates of exploitation there may be no rainforest left in 10 years. If measures are not taken immediately, the greenhouse effect may be unstoppable in 12 to 15 years. -5000 Days to Save the Planet – Edward Goldsmith 1991 "It appears that we have a very good case for suggesting that the El Ninos are going to become more frequent, and they’re going to become more intense and in a few years, or a decade or so, we’ll go into a permanent El Nino. So instead of having cool water periods for a year or two, we’ll have El Nino upon El Nino, and that will become the norm. And you’ll have an El Nino, that instead of lasting 18 months, lasts 18 years," he said. -BBC November 7, 1997

From the 2000s

"But it does not take a scientist to size up the effects of snowless winters on the children too young to remember the record-setting blizzards of 1996. For them, the pleasures of sledding and snowball fights are as out-of-date as hoop-rolling, and the delight of a snow day off from school is unknown." -Dr. Michael Oppenheimer of the Environmental Defense Fund, New York Times – January 2000 Within a few years winter snowfall will become a very rare and exciting event. Children just aren’t going to know what snow is" -Dr David Viner, Senior research scientist at the climatic research unit (CRU) of the University of East Anglia – Mar 20, 2000
