  2. Who do I write a sternly-worded letter to? Animals went into space before we did, just saying. The least we could do is name things after them.

    "If you are disabled, locked doors, ill-placed steps, & illegally parked vehicles can reshape the world into a hostile landscape. That leaves disabled individuals to overcome obstacles through personal ingenuity... Access fails tend to be quiet, desperate battles fought alone."

  4. Climate stripes now go back 2,000 years, providing even more visual context for current warming trends. But watch out: deniers are spreading fake versions. Thanks to for this great visualization tool!

    This behind the scenes look at Sharpiegate should terrify you. Forecasters worried about issuing lifesaving forecasts because they may contradict an errant Trump tweet. What happens when the next hurricane approaches?

  7. Williams: Don’t despair: our world is transforming, but we can bend the curve. Talk about climate change at home and in your communities, support science, get involved. We need each and every one of you!

  8. Williams: Embrace assisted migration/managed relocation. Earth is a fragmented landscape. We can help species move to where they need to be to survive. Similarly, we can assist with evolution through selective breeding to spread resilient populations.

  9. Williams: Vote climate! Tell your elected leaders that climate is an important issue to you. Personal action is important, but we really need action from the top.

  10. Williams: If you read one book on climate solutions, get Drawdown. It’s got seven solutions for slowing climate change.

  11. Williams: Focus on rates of change. Species can actually adapt or move, so long as climate doesn’t change too fast. Let’s keep climate change slow enough so that species can keep up. They’ve had practice.

  12. Williams: We have lots of information about a warming, changing world. So what can we do to slow down and adapt to warning world?

  13. Williams: There’s a cool app that allows you to check out all the geologic and paleontology data as you drive or fly across the country: check out Flyover Country:

  14. Williams: Big and open data are hot now, but paleoecologists have been sharing data since the 1970’s. That’s because our data are hard-won and our questions are big. We’ve built to accumulate it: named after pack rats. They collect bits of the environment; so do we!

  15. This is supposed to be *move, but sure, this works, too!

  16. Williams: Climate change is now a big part of the international conscience: fires in Australia, droughts, melting ice sheets, heat waves, warm winters...people are noticing it in their back yards. And that’s with only one degree Celsius of warming in the last century!

  17. Williams: Big animals like mammoths, mastodons, North American horses and camels are the poster children of ice age extinction. Climate may have stressed these populations, but because almost only big animals died out, humans likely played the bigger role.

  18. Williams: Only one North American plant species is known to have gone extinct, a species of spruce found in ice age fossil deposits the southeastern US. This tell us plants are superstars at climate resilience.

  19. Williams: Species don’t move in lockstep: each has its own climate preferences. We can’t expect ecological communities to stay cohesive, and that’s ok. Species will reshuffle as climates change.

  20. Williams: Pollen recorded in lake cores shows us that when climates changed in the past, tree species shifted their ranges by hundreds of kilometers. That’s one way species can be resilient to warming—they love!

  21. Williams: During the last deglaciation, Greenland ice cores record abrupt warming events of >10 degrees in 1-3 years (!). While current global warming is on the fast end of geologic history, the North Atlantic has experienced very fast rates of warming, and species survived!
