Dr. James Hansen's Must See TED Talk: Starting To Reduce CO2 In 10 Years Is Too Late

“It would be immoral to leave these young people with a climate system spiraling out of control.”
by Dan Miller

NASA climate scientist James Hansen gave a talk at the TED conference in Long Beach, CA on February 29th where he laid out the case for taking urgent action to reduce greenhouse emissions.

Dr. Hansen’s talk began by describing his personal journey, originally studying Venus under Prof. James Van Allen and then working at NASA on an instrument to study Venus’ atmosphere. But after being asked to do some calculations of Earth’s greenhouse effect, Dr. Hansen resigned from the Venus mission to work full time studying Earth’s atmosphere “because a planet changing before our eyes is more interesting and important – its changes will affect all humanity.”

Dr. Hansen and some colleagues published a 1981 paper in Science Magazine that concluded that “observed warming of 0.4C in the prior century was consistent with the greenhouse effect of increasing CO2, — that Earth would likely warm in the 1980s, — and warming would exceed the noise level of random weather by the end of the century. We also said that the 21st century would see shifting climate zones, creation of drought prone regions in North America and Asia, erosion of ice sheets, rising sea levels, and opening of the fabled Northwest passage. All of these impacts have since either happened or are now well underway.”

Dr. Hansen went on to explain that, after speaking out for the need for an energy policy that would address climate change, the White House contacted NASA and Dr. Hansen was ordered to not speak to the media without permission. After informing the New York Times about the situation, the censorship was lifted and Dr. Hansen continued to speak out, justifying his actions with the first line of NASA’s Mission Statement’: “To understand and protect the home planet”. But there were consequences… the reference to the home planet was soon struck from NASA’s Mission Statement, never to return.

Dr. Hansen then went on to describe some of the recent science, including a detailed look at the Earth’s energy imbalance that was made possible by data from 3000 “Argo” floats that measure ocean temperature at different depths. Dr. Hansen said that the current imbalance of 0.6 watts/square meter (which does not include the energy already used to cause the current warming of 0.8°C) was equivalent to exploding 400,000 Hiroshima atomic bombs every day, 365 days per year.

Favorite denier myths such as “it’s the Sun” and “CO2 lags temperature” were addressed by Dr. Hansen and shown to be wrong or irrelevant. He also discussed how amplifying feedbacks in the past took small changes in temperature due to slight changes in the Earth’s orbit and either initiated or ended ice ages. He then said these same amplifying feedbacks will occur today if we do not stop the warming. ”The physics does not change.”

Besides the impacts that are already occurring, Dr. Hansen said that if we do not stop the warming, we should expect sea levels to rise this century by 1 to 5 meters (3 to 18 feet), extinction of 20 to 50% of species, and massive droughts later this century. He said that the recent Texas heat wave, Moscow’s heat wave the year before, and the 2003 heat wave in Europe we “exceptional” events that now occur 25 to 50 times more often than just 50 years ago. Therefore, he concluded, we can say with high confidence that these heat waves were “caused” by global warming.

JR: The Compelling Street Art of a Guerrilla-Photograffeur

The illusive JR has pasted gigantic portraits all over the world, and the public still doesn’t know the artist’s full name. He insists on JR, which are his real initials. He refers to his performance-exhibitions as the mix of photography with graffiti art. His work involves showing up in a shantytown in Kenya or a favela in Brazil, a place where some event has been noted in the media and has captured his attention. His work turns it inside out, photographing the residents, then wrapping their buildings with the results, on a scale so vast that you can see their eyes from the sky.

Often he works through the night, and as soon as he’s done, he disappears; so when the installation becomes front-page news, there is no one left to explain it but the people whose voices had not been previously heard. As a woman from Kibera, a neighborhood in Nairobi, put it in Women Are Heroes, a documentary recently released in France that JR made about his work: “Photos can’t change the environment. But if people see me there, they’ll ask me: ‘Who are you? Where do you come from?’ And then I’m proud.”

JR’s collection of works entitled “Women Are Heroes” features a compelling and empowering style focused on the struggles of women in society today. JR was recently awarded the 2011 TED Prize for “Women Are Heroes.” At the age of 28, JR is the youngest recipient of the $100,000 prize.

JR’s latest project is “The Wrinkles of the City,” an installation of street pieces in Shanghai (and later, in other large cities). The project features images of the elderly, who represent the memory of the city. The photographs have been pasted up at locations that he feels speak to the heritage of a city that has definitely had its share of ups and downs, “from the Japanese occupation, the establishment of the Communist Party, The Liberation, World War II, the end of the foreign concessions, the victory of Mao Zedong over the General Tchang Kaï-Chek’s troops, the Cultural Revolution, the Great Leap Forward to the actual development of the city.“

This piece includes a number of high-resolution color photographs, a slide show and three documentary short films.
