About James Hansen

James E. Hansen, an American climate scientist and one of the earliest advocates for action on climate change, was born on March 13, 1941, in Morristown, New Jersey. His interest in science began at a young age, nurtured by his father, who was a chemist. Hansen earned his undergraduate degree from Iowa State University in 1963 and his Ph.D. in physics from the University of Iowa in 1970. In 1981, Hansen joined NASA's Goddard Institute for Space Studies (GISS), where he conducted groundbreaking research on the greenhouse effect and global climate change. His work at GISS culminated in a 1988 testimony before the U.S. Senate, during which he provided compelling evidence that human activities were causing global temperatures to rise. This testified hearing is often considered the start of widespread public awareness about anthropogenic climate change. Hansen's major works include "Stratospheric Water Vapor and the Albedo Effect," published in 1981, which proposed that changes in stratospheric water vapor could significantly influence Earth's climate. In 2007, he co-authored "Target Atmosphere: A Blueprint for Climate Stabilization," which outlined a plan to reduce greenhouse gas emissions and stabilize the atmosphere. Throughout his career, Hansen has faced criticism and controversy for his activism. However, his unwavering commitment to raising awareness about climate change and advocating for policy action has made him one of the most influential figures in the field. In 2013, he retired from NASA but continues to be involved in climate research and activism through the Climate Science, Awareness, and Solutions (Climate SAS) program at Columbia University's Earth Institute.

Interpretations of Popular Quotes

"I feel like Job. I've been whipped with the sow's ear, and now I'm supposed to shape it into a silk purse."

This quote by James Hansen expresses a feeling of frustration and futility in the face of overwhelming challenges. Comparing himself to Job from the Bible, he suggests that he has been given an unappealing task (whipped with a sow's ear), and is now expected to transform it into something desirable (a silk purse). In this context, the sow's ear represents a difficult or seemingly impossible situation, while the silk purse symbolizes a favorable outcome or solution. Hansen implies that tackling climate change, like Job faced his trials, requires immense effort and ingenuity to turn an undesirable state into something positive and desirable.

"The debate is over. The planet is warming."

This quote by James Hansen, a prominent climate scientist, indicates that the scientific consensus regarding global warming or climate change is no longer debatable. The evidence from numerous studies, observations, and data points towards an undeniable increase in Earth's average temperature, which is largely driven by human activities such as burning fossil fuels and deforestation. Therefore, the focus should shift from debate to action, as the planet needs immediate measures to mitigate further warming and its potential catastrophic impacts on our environment and society.

"We have a moral obligation to leave the planet in at least as good a state as we found it, for our children and future generations."

This quote by James Hansen emphasizes that each generation has a responsibility towards posterity, encompassing not only our biological offspring but also the collective human family of future generations. He advocates for sustainability, urging us to respect the planet we inhabit by preserving its natural resources and minimizing our negative impact on it. This ethical stance is rooted in the belief that a healthy environment is crucial for the survival and well-being of humanity. In essence, this quote underlines the importance of intergenerational equity and stewardship of Earth's bounty.

"It's not just about the temperature record; it's the whole constellation of climate changes that are unfolding right now."

James Hansen's quote emphasizes that the issue of global warming is not solely about rising temperatures as recorded in historical data, but encompasses a broader spectrum of climate change events and phenomena happening concurrently across the planet. These may include extreme weather patterns, sea-level rise, melting ice caps, ocean acidification, loss of biodiversity, and shifts in ecosystems, among others. In essence, he's stating that we need to pay attention not only to temperature increases but also to the overall health and stability of our planet's climate system.

"Climate change is largely caused by human activities, mainly burning fossil fuels like coal, oil, and gas for electricity, heat, and transportation."

This quote by James Hansen highlights the primary cause of climate change as human activities that involve the combustion of fossil fuels such as coal, oil, and natural gas. The burning of these fuels releases greenhouse gases like carbon dioxide into the Earth's atmosphere, trapping heat and causing a rise in global temperatures - a phenomenon commonly known as global warming or climate change. This is particularly significant for electricity generation, heating, and transportation sectors since they consume large amounts of fossil fuels. The message emphasizes the importance of transitioning to renewable energy sources and sustainable practices to mitigate the effects of human-induced climate change.

If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.

The fact is fossil fuel carbon will stay in the surface climate system for millennia.

What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile.

I was lucky to grow up at a time when it was not difficult for the child of a tenant farmer to make his way to the state university.

We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.

You can't turn on your television without seeing these advertisements about clean coal, clean tar sands and the claim that there's more jobs associated with fossil fuels than other industries. That's of course not true. But they're hammering that into the voters' heads.

I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.

Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.

After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with climate change. So, I decided to give one talk, and then it snowballed into another talk and eventually to even protesting and getting arrested.

Consider the perverse effect cap and trade has on altruistic actions. Say you decide to buy a small, high-efficiency car. That reduces your emissions, but not your country's. Instead it allows somebody else to buy a bigger S.U.V. - because the total emissions are set by the cap.
