    From Copenhagen to Paris: Low Expectations

    As we head to Paris, the expectations are profoundly lower. The national commitments that countries are putting on the table do not add up to nearly enough to keep us within 2 degrees; instead the plan is to come back every five years and hopefully do better. … It is still mathematically possible to stay…

  • How Bad Will this El Niño Be? Worse Than You May Think

    How Bad Will this El Niño Be? Worse Than You May Think

    Today’s El Niño is unfolding over a world that is in many ways more vulnerable than the world of 1997-1998. Just as today’s climate continues to generate extremes without historical precedent, we are starting to see elements of social vulnerability also without historical precedent. That is an alarming combination.

  • Climate Is Changing Fast in West Antarctica

    Climate Is Changing Fast in West Antarctica

    Fast-rising temperatures on the Antarctic Peninsula are having an impact on the ice and marine life, and providing clues about future ecosystem changes elsewhere.

    From Copenhagen to Paris: Likely to Fail Again?

    All of the pledges made in Paris will be voluntary. However, countries have not always fulfilled their pledges in the past, and it isn’t obvious that this agreement is going to cause countries to behave very differently in the future.

  • Peat Fires Choking Southeast Asia Pose a New Threat to Global Climate

    Peat Fires Choking Southeast Asia Pose a New Threat to Global Climate

    The Indonesian peat fires that have been choking cities across Southeast Asia with a yellow haze are creating more than a local menace—burning peat releases immense stores of CO2, contributing to global warming.

  • Before Paris, Cause for Optimism

    Before Paris, Cause for Optimism

    If the international community were to fully understand the threat of climate change, and the likely cost of mitigation and adaptation, perhaps we would commit to continued tax breaks and incentives, and propel the renewable energy transition toward completion. In the long run, I am sure this would be less expensive than coping with the…

    What Everyone Should Know About Climate Change

    Young scientists sum it up: The climate is changing. We’re causing it. It’s going affect everyone, and be expensive. But we can do something about it. Watch the video…

  • 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…

  • ExxonMobil and the Distortion of Climate Science

    What protection can we fall back on when a giant, powerful, multinational corporation leads an effort to change the nature of reality itself and redefine scientific fact? The answer is of course, is the protection of other powerful institutions: research universities like the one I work for, the Congress, and, in this case, the New…
