    Carbon Lurking in Deep Ocean Threw Ancient Climate Switch, Say Researchers

    A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the…

    Uncovering the Stories of Southern Africa’s Climate Past

    Sidney Hemming is preparing to spend two months at sea studying global ocean circulation and southern Africa’s climate variability over the past 5 million years.

    An Interactive Map of Scientific Fieldwork

    Earth Institute scientists explore how the physical world works on every continent — over and under the arctic ice, in the grasslands of Mongolia, on volcanoes in Patagonia, over subduction zones in Papua New Guinea, and on the streets of New York City.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
