    Fixing Climate: Beyond Carbon Dioxide

    Climate scientists at a meeting of the American Association for the Advancement of Science this week were elated to hear that the United States and five other countries had agreed to work toward cutting pollutants other than carbon dioxide thought to cause about a third of current human-influenced global warming. After all, many of them…

    A Climate Tipping Point for World Food Prices?

    Increased growing-season heat due to climate change in coming decades could push staple U.S. crops off a cliff, and cause world food prices to jump, a Columbia University economist told a press briefing at a top scientific meeting this week. In a panel organized by the American Association for the Advancement of Science, economist Wolfram…

  • Can Intensive Farming Save Tropical Forests?

    Can Intensive Farming Save Tropical Forests?

    With 7 billion people on the planet and some 40 percent of earth’s land surface already covered with croplands and pastures, the only remaining frontiers for agricultural expansion are dwindling tropical forests. Some see high-yield industrial-scale farming as a way to take the pressure off; the theory goes that if more produce can be grown…

  • Did the Oceans Influence Human Evolution?

    Did the Oceans Influence Human Evolution?

    Scientists often invoke climate as a possible factor in human evolution; but only recently have they developed the ability to get enough information about past climates and related fossil evidence to see any details. A half-dozen leading paleontologists and climate scientists discussed recent advances in a symposium this week at the annual meeting of the…

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.
