Via Brendon Slotterback’s Twitter, here’s a chart showing Minneapolis’ energy use and “built square footage” (i.e. the total amount of buildings) over time: As Slotterback says: Minneapolis’ total electricity use has declined 4% since ’06 while total square footage has increased 5.5%.

Chart of the Day: Minneapolis Temperature, Dew Point, Wind Direction, Precipitation Forecast

This isn’t a weather report. Well it is, but that’s not the point. Check out what MPR’s Paul Huttner’s great blog says about “climate disruption.” First your forecast: OK, that’s summer. But the real eye-raising part is Huttner’s link to the Weather Channel’s list of top 25 cities for climate disruption. For some reason, Minneapolis […]

Here are the projected changes: For anyone serious about climate change, thinking about mode share and transportation patterns is crucial to actually slowing our emissions growth. It’s […]

Chart of the Day: Annual Global Temperature Anomaly Relative to a Base Average

From a blogger that devotes their life to debunking climate denial comes this chart… If you’re younger than 30, you’ve never experienced a month in which the average surface temperature of the Earth was below average. […] The variability we observe in surface temperature comes primarily from understood patterns of weather. Many have heard of El […]

Chart of the Day: Daily Incoming Solar Radiation (By Latitude)
