Chart of the Day: US CO2 Emissions Trends by Sector

Via Fast Company, here’s a chart showing the national CO2 emissions trends from 1990 to 2014, divided up by sector as a percentage of the whole. As you can see, though emissions relative to each other remain largely stable, there is clear trend where transportation emissions are becoming a larger piece of the pie. Here’s the chart: Charlie […]

Map Monday: Minnesota’s Carbon Donut

I love interactive maps and one got my attention recently. Christopher M. Jones and Daniel M. Kammen at UC Berkeley published a study in 2013 taking data on household carbon footprints to develop carbon profiles of zip codes, cities, counties, and states. They took the carbon profile data and produced an interactive map of the […]

Chart of the Day: CO2 Emissions vs. Cycling Modeshare

Here’s a chart from a recent study by the Institute for Transportation and Development Policy (ITDP), a big International thinktank, about the relationship between CO2 emissions and bicycling modeshare (i.e. the percentage of people who use one mode of travel vs. another). They ran two scenarios about how urban bicycling could affect greenhouse gas emission. […]

Chart of the Day: Minneapolis Electricity vs. Built Square Footage over Time

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%. At the global scale, preventing out of control climate change requires de-linking GDP […]

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 […]

Chart of the Day: Forecast Greenhouse Emissions by Mode

Via Todd Graham on Twitter, here’s a chart that shows traffic projections that I can get behind: future emissions by mode in Minnesota, given some assumptions about traffic and fuel. 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 […]
