James Hansen

Ultimately sea levels will rise several feet, given the present levels of CO2 in the atmosphere. We already knew this by examining paleo data, and finding periods in the past with similar surface temperatures and/or similar atmospheric CO2 levels as today.
I put a graphic from a paper by Gavin Foster and Eelco Rohling at the top of the post. It does a good job of summarizing the paleo data.
If we keep pumping CO2 into the atmosphere at current, or even somewhat reduced, levels for a few more decades, the ultimate increase in sea levels will be significant. Find the 400–500…
gregladen | August 4, 2013From Nick Breeeze, "This video contains excerpts from interviews with Dr James Hansen. Here he gives his view on how we can get emissions from burning fossil fuels under control."
gregladen | July 23, 2013James Hansen, the famous climate scientist and author of Storms of my Grandchildren, talks about the possible role of nuclear power in addressing climate change, and in particular, reducing the release of fossil carbon into the atmosphere.
I think he is far to pessimistic on the use of solar and wind energy than he needs to be and notice that he, and no one else ever, seems to mention geothermal, which could reduce our release of carbon by double digit percentages using existing technology in a few years. Having said that, there is probably no way to solve our energy problem without…
gregladen | April 29, 2013James Hansen, author of "Storms of My Grandchildren: The Truth About The Coming Climate Catastrophe and Our Last Chance to Save Humanity", recently announced his retirement from his position as director of NASA's Goddard Institute for Space Studies. My friend John Abraham write's about Hansen's retirement in his inaugural* post in the new blog "Climate Consensus - The 97%" ...
What does this mean for climate science and the future of the Earth? It is impossible to know now but instead of looking forward, I want to shine a light on what Jim has done for climate science, what he signifies to…
denialism | March 8, 2012I think it's a nice, succinct description of the problem of climate change from one of the leaders of the field.
On a related note the nation of Kiribati is relocating to Fiji as their island nation is disappearing.
illconsidered | November 24, 2010As fate would have it, no sooner does a disengenous commenter here point out the unusual cold and snow falling on my hometown of Vancouver, Canada than I come accross this amusing comic from Jen Sorenson:
illconsidered | March 2, 2010Unfortunately for an unscientifically inclined mind, one bitter cold winter is worth many mountains of research in the quest for the truth about climate change. And unfortunately for our choking biosphere, political action will likely remain an impossibility until we are well and truly past the alledged cessation of warming.
I received an apparently sincere comment that expressed what must be a common feeling in the general public:
You guys are so far scientifically over my head that it is impossible
for me to participate in this conversation. But consider that most
people are like me,…
gregladen | December 5, 2009Subtitled "The truth about the coming climate catastrophe and our last chance to save humanity," this might be a book you should read.
James Hansen is probably the world's best known climate scientist, partly because of his own work and his testimony before Congress, and partly because he has become a target of Global Warming denialists who seem to revel in every opportunity to accuse him of fraud, deceit, or incompetence.
In Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity, Hansen provides a message that is much more severe…

There have been few more passionate and prescient figures in the history of science than the Russian naturalist and political radical Peter Kropotkin. Upon the confirmation of his geological research that demonstrated an ancient ice sheet had once extended across the Russian landscape, this evolutionary theorist and gentle anarchist reported in 1894 that "we must accustom ourselves to the idea that climate, like everything else on the earth, is a changeable element." In his many books and articles he regularly…
illconsidered | March 3, 2009Roger puts up another post (guest post, gotta love plausible deniability) about James Hansen:
blah blah blah....dictator who ordered millions of people to be gassed and then burned in crematoria...blah blah blah
No, he isn`t (yet) calling Hansen a Hitler, but we all know how Godwin`s Law works.
Or almost all of us...
[UPDATE: Things Break has a stronger stomach than I do, and he takes a more thorough look at Roger's latest. As usual with Pielke's positions, the closer you look, the less it holds up.]
illconsidered | February 3, 2009Just a quick update on my recent post noting Roger Pielke's lack of integrity:
Roger makes a note of my post and John Fleck's and adds this underhanded toss-off line: Hansen's forecast "did not survive the peer review process" and so did not "appear in PNAS". Of course, the alledged "prediction" of a super El Nino ("there is a good chance") from the draft was not submitted to PNAS for peer review. Roger is refering to Hansen's passing the draft to a few friends and colleagues, inadvertently distributing it more broadly (oops, Roger's not a friend!).
There is a must read exchage at John…
tlambert | January 29, 2009The usual denialists (e.g. The Register) are excited because some guy they never heard of before has joined Inhofe's merry band, writing:
"I appreciate the opportunity to add my name to those who disagree that global warming is man made."
M. J. Murphy has some information about Theon. It seems that Inhofe's claim that Theon was Hansen's supervisor is completely untrue:
Theon wrote to the Minority Office at the Environment and Public Works Committee on January 15, 2009. "I was, in effect, Hansen's supervisor because I had to justify his funding, allocate his resources, and evaluate his…
illconsidered | November 24, 2008This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.Objection:
In his June 23, 2008 testimony before the United States Congress, James Hansen called for the punishment of climate change skeptics for "crimes against humanity". This is a mockery of free speech, the antithesis of scientific investigation and a clear indication that global warming "science" is just another religious persecution like the Catholic Church's persecution of Galileo.
Answer:
The accusation is simply false. James Hansen never…
illconsidered | November 18, 2008This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.Objection:
In October, 2008, Al Gore's science advisor, James Hansen announced yet another "hottest" month on record. After all the alarmist banner headlines sank in, yet another "correction" quietly contradicted this, and October was not particularily warm after all. This is yet another example of why the temperature record can not be trusted.
Answer:
Wow. Where to begin with this one? There are many versions of this myth around already at the time of…
