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
2006 – “It is not a debate over whether the earth has been warming over the past century. The earth is always warming or cooling, at least a few tenths of a degree…” — Richard S. Lindzen, the Alfred P. Sloan professor of meteorology at MIT
2006 – “What we have fundamentally forgotten is simple primary school science. Climate always changes. It is always…warming or cooling, it’s never stable. And if it were stable, it would actually be interesting scientifically because it would be the first time for four and a half billion years.” —Philip Stott, emeritus professor of bio-geography at the University of London
2006 – “Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930’s the media peddled a coming ice age. From the late 1920’s until the 1960’s they warned of global warming. From the 1950’s until the 1970’s they warned us again of a coming ice age. This makes modern global warming the fourth estate’s fourth attempt to promote opposing climate change fears during the last 100 years.” – Senator James Inhofe, Monday, September 25, 2006
2007– “I gave a talk recently (on fallacies of global warming) and three members of the Canadian government, the environmental cabinet, came up afterwards and said, ‘We agree with you, but it’s not worth our jobs to say anything.’ So what’s being created is a huge industry with billions of dollars of government money and people’s jobs dependent on it.” – Dr. Tim Ball, Coast-to-Coast, Feb 6, 2007
2008 – “Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress” – Dr. John S. Theon, retired Chief of the Climate Processes Research Program at NASA, see above for Hansen quotes

2009 – Climate change: melting ice will trigger wave of natural disasters. Scientists at a London conference next week will warn of earthquakes, avalanches and volcanic eruptions as the atmosphere heats up and geology is altered. Even Britain could face being struck by tsunamis – “Not only are the oceans and atmosphere conspiring against us, bringing baking temperatures, more powerful storms and floods, but the crust beneath our feet seems likely to join in too,” – Professor Bill McGuire, director of the Benfield Hazard Research Centre, at University College London, – The Guardian, Sep 2009.
2010 – What Global Warming Looks Like. It was more than 5°C (about 10°F) warmer than climatology in the eastern European region including Moscow. There was an area in eastern Asia that was similarly unusually hot. The eastern part of the United States was unusually warm, although not to the degree of the hot spots in Eurasia. James Hansen – NASA GISS, August 11, 2010.
2011 – Where Did Global Warming Go? “In Washington, ‘climate change’ has become a lightning rod, it’s a four-letter word,” said Andrew J. Hoffman, director of the University of Michigan’s Erb Institute for Sustainable Development. – New York Times, Oct 15, 2011.

2012 – Global warming close to becoming irreversible-scientists. “This is the critical decade. If we don’t get the curves turned around this decade we will cross those lines,” said Will Steffen, executive director of the Australian National University’s climate change institute, speaking at a conference in London. Reuters, Mar 26, 2012
2013 – Global-warming ‘proof’ is evaporating. The 2013 hurricane season just ended as one of the five quietest years since 1960. But don’t expect anyone who pointed to last year’s hurricanes as “proof” of the need to act against global warming to apologize; the warmists don’t work that way. New York Post, Dec 5, 2013
2014 – Climate change: It’s even worse than we thought. Five years ago, the last report of the Intergovernmental Panel on Climate Change painted a gloomy picture of our planet’s future. As climate scientists gather evidence for the next report, due in 2014, Michael Le Page gives seven reasons why things are looking even grimmer. – New Scientist (undated in 2014)
