• Algae could be major new food source, major new industry

    By Richard A Lovett, Cosmos


    "Not only can these fast-growing single-celled plants provide biomass for carbon-neutral fuels, they can provide animal feeds and high-quality protein supplements for a human population that looks to be headed for a peak of about 9.5 to 10 billion, says Charles Greene, an environmental scientist from Cornell University, New York, US."

    We Don’t Deny Harvey, So Why Deny Climate Change?

    By Nicholas Kristof, New York Times


    "“Climate change played a role in intensifying the winds and rainfall associated with Hurricane Harvey,” says Charles Greene, a climate scientist at Cornell. He notes that there’s also a third way, not yet proven, in which climate change may be implicated: As Arctic sea ice is lost, wind systems can meander and create blockages — like those that locked Harvey in place over Houston. It was this stalling that led Harvey to be so destructive."

    Breakthrough in climate change mitigation, renewable energy

    By Chukwuma Muanya, The Guardian


    "By replacing traditional land-based crops with marine microalgae, there will be less carbon dioxide emitted, which could help achieve climate stabilization goals. Greene said that significant research and development investments would be essential over the next decade to improve bioenergy and food production."

    It's Global Warming, Stupid

    By Paul M. Barrett, Bloomberg Businessweek


    "Climate scientists Charles Greene and Bruce Monger of Cornell University, writing earlier this year in Oceanography, provided evidence that Arctic icemelts linked to global warming contribute to the very atmospheric pattern that sent the frigid burst down across Canada and the eastern U.S."

    Endangered right whales are dying in record numbers off Canada, raising alarm

    By Erik Stokstad


    "Right whales may be moving to find denser aggregations of Calanus copepods, a subarctic
    species that prefers relatively cool water, say oceanographers Charles Greene of Cornell University and Erin Meyer-Gutbrod, a postdoctoral researcher at the University of California, Santa Barbara."

  • Japanese Whaling Is Not the Greatest Threat to Whale Conservation

    "Although I would personally prefer that no nation engage in commercial whaling, I find it hypocritical that many Americans and Canadians criticize the Japanese while turning a blind eye to the more pernicious practices of their own countries."

    Why the Fossil Fuel
    Divestment Movement Will Succeed

    By Charles H. Greene (Cornell University) and Daniel M. Kammen (University of California, Berkeley)


    "Why are we so confident that the divestment movement will persuade reluctant administrators and trustees to alter their views on divestment? The answer is simple — because none of them wants to be on the wrong side of history and see their institutions financially crippled by poor investment decisions."


    Turning Climate Change Challenges into Opportunities

    By D. James, Baker Clinton Foundation; Charles Greene, Cornell University; Richard Spinrad, The Oceanography Society; and James Yoder, Woods Hole Oceanographic Institution


    "Rather than argue about what's happening, why not look at the positive side of these challenges? That's where the new engineering opportunities and the profits will be."

    Winning the War on Fossil Fuels

    By Charles Greene and David Willson


    "To win the War on Fossil Fuels, the energy industry must come up with an alternative business model that can sustain its long-term profitability while safeguarding the planet's habitability."

    Frankenstorm Sandy: Stitched Together from Elements Both Natural and Unnatural

    By Charles Greene


    "Would this monster hybrid storm have emerged without the effects of global climate change? I don't think we will ever be able to answer that question without some ambiguity. What I will say is that the climate system is now predisposed to favor the development of such unusual storms both this week and in the future."

    Gambling away our clean-energy future?

    By Charles Greene


    "Therefore, the question is not whether society will discontinue using fossil fuels, but rather whether the transition to a clean-energy economy can be completed before we do irreparable damage to the Earth's climate system."

    Did global warming cause hurricane Irene?

    By Charles Greene


    "Scientists can't say that global warming caused hurricane Irene or Katia or tropical storm Lee. But they can say that global warming produces the conditions that lead to hurricanes. Americans should be reducing greenhouse gas emissions and preparing for severe weather to come."

    The Winters of Our

    By Charles Greene


    "A weakened jet stream exhibits larger waves in its trajectory, which can get stalled in place, locking an affected region such as the northeastern U.S. in a prolonged deep freeze."

    Global Warming, Winter Weather and the Olympics– Leading Climate Scientists Weigh In

    By Andrew Revkin; Addended Note by Charles Greene


    "The lag between decreases in sea ice extent during late summer and changes in the mid-latitude atmospheric circulation during other seasons (like autumn and winter, when the recent loss of sea ice is much smaller) have been demonstrated empirically, but have not been captured by existing dynamical models. It is time for theory to be reconciled with the observations."

    Emissions reduction is not enough

    By Greg Rau and Charles Greene


    "Reaching the needed atmospheric CO2 level requires not only rapid reduction in emissions, but also post-emissions draw-down of atmospheric CO2 through natural CO2 sinks and by thus far little-researched and unproven “negative emissions” technologies."

    Years of Living Dangerously

    National Geographic Channel, Science Advisor

    "Scientists are trained to be skeptics. New scientific ideas come along, and we’re going to be skeptical about them. We need to observe things with our own eyes to convince ourselves what is really happening. However, if a scientist is still skeptical about the reality of climate change, then there is a good change that he or she is ideologically blinded, delusional, or in the pocket of some special interest group."
