No, the Yellowstone supervolcano is not ‘overdue’

Why mega-eruptions like the ones that covered North America in ash are the least of your worries.

  • The supervolcano under Yellowstone produced three massive eruptions over the past few million years.
  • Each eruption covered much of what is now the western United States in an ash layer several feet deep.
  • The last eruption was 640,000 years ago, but that doesn't mean the next eruption is overdue.

  • Species richness among wild bees and other pollinators has been declining for 50 years.
  • A new study found crops like apples, cherries, and blueberries to be pollination limited, meaning less pollination reduces crop yields.
  • Conservation efforts will need to be made to stave off future losses and potential food insecurity.

    'A world with no ice': Confronting the horrors of climate change

    The complacent majority needs to step up and call for action on climate change.

    • Climate change is often framed as a debate that has split society down the middle and that requires more evidence before we can act. In reality, 97 percent of scientists agree that it is real and only 3 percent are skeptical. A sticking point for some is the estimated timeline, but as Columbia University professor Philip Kitcher points out, a 4-5 Celsius temperature increase that makes the planet uninhabitable is a disaster no matter when it happens.
    • In this video, 9 experts (including professors, astronomers, authors, and historians) explain what climate change looks like, how humans have already and are continuing to contribute to it, how and why it has become politicized, and what needs to happen moving forward for real progress to be made.
    • David Wallace-Wells, journalist and New America Foundation National Fellow, says that the main goal of climate action is not to win over the skeptical minority, but to "make those people who are concerned but still fundamentally complacent about the issue to be really engaged in a way that they prioritize climate change in their politics and their voting and make sure that our leaders think of climate change as a first-order political priority."
