Currently in Chicago — November 1, 2023: A chilly Day of the Dead

The weather, currently.

Halloween weather will be more of a trick than a treat this year. We’ll see snow showers mixed with rain, morphing into all snow after 11pm and a low of 30. The wind will pick up too, with gusts up to 40mph after midnight, and we even have a chance of thundersnow. But it’s not going to be much snow, less than half an inch, and it’s not going to stick.

Wednesday will be mostly sunny with a high of 44, and Wednesday night will be mostly cloudy with a low near 35. May you find a meaningful way to remember the lives of those you’ve lost this year, whether you celebrate Samhain or Día de los Muertos or All Souls Day.

What you need to know, currently.

The data are in, and October 2023 was the hottest October in history.

With a year so unusually warm as this, it’s sometimes easy to assume that scientists didn’t see it coming. That’s not quite true. In fact, global climate models created 10 years ago still are doing a great job of capturing how extreme this year is.

And it’s not just this year. In general, global temperatures in recent years have been tracking right along the middle of where scientists thought they’d be by now assuming emissions kept rising. (They have.) In fact, temperatures are not too far off from where scientists back in the 1980s thought they’d be right now, assuming a scenario of only limited climate action came true. (It has.)

So, we saw this coming. And we should have done more to stop it. And we know that ramped up action in the coming years will still work.

In the 35 years since the 1988 congressional testimony of NASA climate scientist James Hansen, humanity has now used effectively all of its atmospheric carbon budget for keeping global warming at or below 1.5°C since preindustrial levels. But it doesn’t have to go much further than that if we do what we know we need to do.
