Um pequeno sumário sobre o mudanças climáticas.

  • O pessoal do blog ButNowYouKnow fez um pequeno sumário sobre as opiniões/discussões sobre as mudanças climáticas da Terra. Para acessar mais informações, gráficos, etc. clique aqui, e bom aprendizado.

  • 1938 - Global warming, caused by man heating the planet with carbon dioxide, “is likely to prove beneficial to mankind in several ways, besides the provision of heat and power.”– Quarterly Journal of the Royal Meteorological Society
  • 1938 - “Experts puzzle over 20 year mercury rise…Chicago is in the front rank of thousands of cities thuout the world which have been affected by a mysterious trend toward warmer climate in the last two decades” – Chicago Tribune

  • 1974 - “As for the present cooling trend a number of leading climatologists have concluded that it is very bad news indeed” – Fortune magazine, who won a Science Writing Award from the American Institute of Physics for its analysis of the danger
  • 1974 - “…the facts of the present climate change are such that the most optimistic experts would assign near certainty to major crop failure…mass deaths by starvation, and probably anarchy and violence” – New York Times
  • Cassandras are becoming
    increasingly apprehensive,
    for the weather
    aberrations they are
    studying may be the
    harbinger of another
    ice age
  • 1975 - Scientists Ponder Why World’s Climate is Changing; A Major Cooling Widely Considered to Be InevitableNew York Times, May 21st, 1975
  • 1975 - “The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind” Nigel Calder, editor, New Scientist magazine, in an article in International Wildlife Magazine
  • 1976 - “Even U.S. farms may be hit by cooling trend” – U.S. News and World Report
  • 1981 - Global Warming – “of an almost unprecedented magnitude” – New York Times
  • 1988 - I would like to draw three main conclusions. Number one, the earth is warmer in 1988 than at any time in the history of instrumental measurements. Number two, the global warming is now large enough that we can ascribe with a high degree of confidence a cause and effect relationship to the greenhouse effect. And number three, our computer climate simulations indicate that thegreenhouse effect is already large enough to begin to effect the probability of extreme events such as summer heat waves. – Jim Hansen, June 1988 testimony before Congress, see His later quote and His superior’s objection for context
  • 1989 -”On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but – which means that we must include all doubts, the caveats, the ifs, ands and buts. On the other hand, we are not just scientists but human beings as well. And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climate change. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This “double ethical bind” we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.” – Stephen Schneider, lead author of the Intergovernmental Panel on Climate Change, Discover magazine, October 1989
  • 1990 - “We’ve got to ride the global warming issue. Even if the theory of global warming is wrong, we will be doing the right thing – in terms of economic policy and environmental policy” – Senator Timothy Wirth
  • 1993 - “Global climate change may alter temperature and rainfall patterns, many scientists fear, with uncertain consequences for agriculture.” – U.S. News and World Report
  • 1998 - No matter if the science [of global warming] is all phony . . . climate change [provides] the greatest opportunity to bring about justice and equality in the world.” —Christine Stewart, Canadian Minister of the Environment, Calgary Herald, 1998
  • 2001 - “Scientists no longer doubt that global warming is happening, and almost nobody questions the fact that humans are at least partly responsible.” – Time Magazine, Monday, Apr. 09, 2001
  • 2003 - Emphasis on extreme scenarios may have been appropriate at one time, when the public and decision-makers were relatively unaware of the global warming issue, and energy sources such as “synfuels,” shale oil and tar sands were receiving strong consideration” – Jim Hansen, NASA Global Warming activist, Can we defuse The Global Warming Time Bomb?, 2003
  • 2006 - “I believe it is appropriate to have an over-representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis.” — Al Gore, Grist magazine, May 2006
  • Now: The global mean temperature has fallen for two years in a row, which is why you stopped hearing details about the actual global temperature, even while they carry on about taxing you to deal with it…how long before they start predicting an ice age?
