  • Governor Andrew Cuomo’s Quiet Green Revolution

    In many respects, Cuomo’s approach to sustainability mirrors the approach taken by Mike Bloomberg when he was New York City’s mayor. Sustainability is viewed as a tool of economic development and environmental goals are integrated into the goals of economic development.

    From Good Intentions to Deep Decarbonization

    The most important issue is whether countries will achieve their 2030 targets in a way that helps them to get to zero emissions by 2070. If they merely pursue measures aimed at reducing emissions in the short term, they risk locking their economies into high levels of emissions after 2030. The critical issue, in short,…

  • From Copenhagen to Paris: Moving From Talk to Action on Climate Change

    Globally, individual nations have volunteered greenhouse gas reduction targets in anticipation of the Paris meetings. Unlike Copenhagen, where calls for mandatory reductions and transfer payments to the developing world caused the collapse of any potential agreements, the world community seems more realistic as it approaches the Paris meetings.

  • Growing the Global Economy Without Destroying the Planet

    We need to focus our attention on the existing systems of management and influence now in place and attempt to turn them toward sustainability. This includes national, state and especially local governments, corporations and nonprofit organizations.

  • Climate Through A Different Lens: Poverty, Inequality, Sustainability

    Climate Through A Different Lens: Poverty, Inequality, Sustainability

    Technology has brought us low-cost global communication, and also enabled a global economy. It has also brought us closer and further from each other. We now know more about other cultures. We also see the differences, and sharpen our sense of inequities. Perhaps, this, rather than a control of greenhouse gases, needs to be the…

  • Getting Sustainability on the Agenda of Our Dysfunctional Federal Government

    What is needed politically and in reality is a positive vision of a sustainable society. In the case of this country it will need to be built on the traditional values that have always attracted people to America: freedom, rewarding individual achievement, a love of the new and novel, innovation, and acceptance (even if reluctantly)…

  • The White House Pushes Clean Energy While Coal States Push the Past

    The fact that we are addicted to energy and still require fossil fuels should not be taken to mean that we couldn’t get off of fossil fuels while increasing energy efficiency. We can and we will. But no one is going to give up the current energy system until a cleaner one comes along that…

    Citi’s Sustainability Strategy

    In 2015, Citi announced a new environmental finance goal to lend, invest and facilitate $100 billion over 10 years towards activities focused on environmental solutions and reducing the impacts of climate change globally.

    For Sustainability, Rethink Our Systems

    Increasingly, systems thinking is embraced as a critical framework for approaching sustainability and resilience. Such an approach helps us look beyond an analytical, cause-and-effect mode of doing business that often only yields short-term solutions and unintended consequences.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
