    The Connection Between Climate and Public Health

    International Research Institute for Climate and Society and the Mailman School of Public Health will hold a two-day meeting to talk about how climate influences issues of public health, from heat waves to infectious diseases. The event will be livestreamed, and you also can follow it on Twitter at #healthclimate2016.

    Trump vs. Clinton: What the Election Could Mean for Climate Policy

    The outcome of this year’s presidential election could have far-reaching implications for the fate of our planet because the two presumptive candidates, Democrat Hillary Clinton and Republican Donald Trump, have very different ideas about climate change. What will they do about the Paris accord and climate change?

    Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests

    Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.

    The 2 Million Year Melee: Neanderthals vs. Humans

    Given their adaptation to cold climes and their advanced, albeit under-appreciated, skills, how were Neanderthals beaten out by their human counterparts? The answer lies in a combination of culture and genetics that enabled the successful radiation of humans.

    Columbia, What Is Our Role in Responding to Climate Change?

    We often think of the fight against climate change on a national or international level, but what can we do as a community?

    Study Downgrades Groundwater Contribution to Sea Level Rise

    Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially lower.

    Maureen Raymo Elected to National Academy of Sciences

    Maureen Raymo, a marine geologist at Lamont-Doherty Earth Observatory whose name is connected with key theories about how ice ages wax and wane and how sea levels change, has been elected to the National Academy of Sciences, one of the highest honors awarded to scientists in the United States.
