Historical Chicago Snowfall

Snow should fall upon Chicago this afternoon and it may measure up to a few inches in depth. But much of this winter has been below average. And that is much the same from last year when snowfall did not even reach 20 inches.

I went through NOAA data to look at the last decade of monthly snowfall to see just how little snow has fallen this winter. (Not a lot.) And then I looked at the entirety of the NOAA records to see where 2011/2 fit in the span of winters. (One of the least snowy.) This graphic is the result.

Setting Up a Snowstorm

This weekend I researched meteorological data for a graphic that I will post tomorrow. But in doing that research I came across a series of weather infographics from WGN that are better than the average. The one below details the snowstorm due to impact the Chicago area and how it will form (along with the storm that brought a few inches of snow last week).

Forecasting Snowfall

So that fishy little storm the Weather Channel called Nemo—you may have heard of it—put a little snow across New England. Last week the New York Times published an interactive infographic that looked at when and where the snow would be falling, from New Jersey to New York to Maine.

The times are cut into six-hour blocks and show in the upper left where the snow would be falling by rate per six-hours. To the right of the map is a series of bar charts that show the snowfall pattern in more or less of a wave. Beneath all of it are a comparison of when, over the last several decades, the largest snowstorms hit Boston and New York (and how much snow each city received). A comparison of the map before to the end of the storm, except for parts of Maine.

The Sky Is Falling…No…Wait…It’s Just a Dream(liner)

Boeing has been having some problems with its new aircraft, the 787 Dreamliner from cracked windshields to oil leaks to perhaps most problematic battery problems. Over the course of the last week, the New York Times has published a series of small graphics to complement stories about the problems and the investigations.

The first graphic looked at the Dreamliner and where its batteries are located. Unfortunately for Boeing, the Dreamliner is critical to its success moving forward and the remainder of the graphic shows just how important.

The next day a graphic about total deaths on US airline flights supported a piece about the Dreamliner.

Then yesterday the NYT published a graphic about the specific battery type (lithium ion) and what role it played in aircraft incidents, be them cargo or passenger related.

2012 Was the Hottest Year on Record

2012 was the hottest year since 1895. That’s 117 years by my count. Of course just being the hottest year ever recorded does not mean everywhere was warmer than usual. Some places were cooler. And the New York Times looked at the US pattern of warmer and cooler than average temperatures. Below the map are small multiples of charts recording the number of days above or below the normal for that day.

That's a lot of warmer than average temperatures…

And for anecdotal evidence, I will say that this past summer was godawfully hot in Chicago.

The Threat of Climate Change

We are warming the planet. And like ice cubes in a glass of water on a hot summer’s day, Earth’s ice caps will, over the course of centuries, begin to melt and contribute to a rise in sea level. Unfortunately, most of the world’s population lives close to shorelines or the rivers connecting continental interiors to the sea. The world for the generations of children following us may very well look much different than it does today.

The New York Times uses an interactive piece to show how sea level rises will impact coastlines and inland ports in the United States. Using a slider, the user can investigate sea level changes of the expected five feet over the next one to three centuries, or two longer-term scenarios that are not yet certain but possible. Below are a few of the 24 cities and metropolitan areas.

In Philadelphia, a rise of 25 feet inundates South Philly, Old City, Fishtown, Kensington, Port Richmond and the other neighbourhoods close to the Delaware. The Jersey Shore still exists. It has just moved dozens of miles inland. The Cape May Peninsula is well submerged.

More Evidence on Why You (I) Need a Good Night’s Sleep

The Washington Post looks at sleep and how lack thereof may lead to various health problems, including Alzheimers, diabetes, and others. Maybe this means I have a reason to sleep in the mornings now…probably not.

US Healthcare State Exchanges

Later this month the Affordable Care Act mandates states decide on how they wish to implement the state healthcare exchanges. The Guardian’s US interactive team has created this interactive application to track the state decisions. Each state is clickable to provide further details on what has been decided.

Twinkle, Twinkle, Little—Damn That’s Bright.

We’ve had a lot of the rough and gritty politics of late. So now for some  bright and starry-eyed idealism. Well, maybe less idealism and more stars. Lots of them. Courtesy a Google Chrome experiment.

Uncertain Planet

Someday humanity will find a planet amongst the stars similar in temperament to Earth. One of the best star systems to explore is Gliese 581, a small and faint star some 20 light years away. Calculations show that there are a few planets that could exist in or near what is often called the Goldilocks Zone. The Goldilocks Zone describes the distance from the systems’ star where planets could exist with liquid water. But generally, one needs to take that with a grain of salt. Here in the Sol System, for example, Earth is joined by Venus and Mars. But neither of those planets appear capable of sustaining life at least at present.

The problem with Gliese 581 is that we are not yet certain as to exactly how many exoplanets form the planetary system. It might be four; it might be five. The different schools of thought lead to different conclusions about the possibility of there being liquid water. And life as we know it requires water. The New York Times looked at Gliese 581 earlier this summer and compared the two different orbital models.
