This is a page about pollution, global warming, and how they affect us. It contains blog posts and tools related to it. A primary focus is making global warming data easier to understand through the use of data visualizations, summaries of model runs, etc. Some questions that I try to answer are:
  • How will global warming affect specific locations?
  • What climate change impacts have we seen already?
  • Can we stop global warming?
  • What are some of the subtle effects of pollution?
Feel free to contact me at roberthamner@gmail.com for any questions or suggestions.

Atmospheric CO2 API

I've added a new tool that you can use that returns atmospheric CO2.

I looked for a nice API to return the current atmospheric CO2 levels and couldn't find one, so I wrote one to share. If you go to http://cityprojections.com/php/weeklyco2.php, you will get a JSON string with the most recent weekly average, the average from this week a year ago, the average from this week a decade ago, and the historic average (1850 currently).

The first three are Mauna Loa CO2 readings and come from the NOAA and the historic one comes from NASA. An example usage is included below:
