To most scientists including us at the AIRE team, it is obvious that contrails have a simple physical explanation and are not evidence of secret chemical spraying. In fact, it is so obvious that it would never have occurred to most of us to spend the time and energy to conduct and publish a survey on the topic. But until now, a nonexpert wanting to find out the truth about this by searching on the internet would encounter tons of sites filled with misinformation and conspiracy theories, and very little legitimate scientific information. Hopefully this article (and press covering it, like this NY Times article) will be near the top of the Google search results for a while.
Moms Clean Air Force is an organization of families fighting against environmental pollution. Their website is full of excellent resources, with information on such topics as indoor air pollution, fracking, smog, and more. Our favorite feature is the “mom detective.” They have a very active and interesting twitter feed at @CleanAirMoms. Moms Clean Air Force is sponsored by the Environmental Defense Fund.
Moms Clean Air Force es una comunidad de familias unidas contra la contaminación del medio ambiente. Su sito del web (enlace por debajo) es muy informativo y interesante, con muchos recursos en español sobre temas incluso: contaminación del aire en interiores, la fractura hidráulica (fracking), y el smog.

Scientists and educators from NASA and UCAR have written a storybook entitled “What’s Up in the Atmosphere? Exploring Colors in the Sky” aimed at elementary school-aged (K-4) children, in which atmospheric aerosols play a starring role. The story follows a group of curious students who, under the guidance of their teacher, investigate the connection between the appearance of the sky and asthma symptoms in their fellow students on a given day. The students in the story (and the readers) learn about atmospheric aerosols in the process. The storybook includes a teachers’ guide with glossary.
This long winter has had the AIRE team thinking about the amount of time we spend indoors, and the air quality there.
– These days, most people spend the vast majority of their time indoors (especially in the winter!). There is therefore high potential for exposure to pollutants indoors, i.e., at home or in the workplace.
– While what we think of as commonplace outdoor pollutants (e.g. car exhaust) may be less prevalent indoors than outdoors, other chemicals such as volatile organic compounds (VOCs) can be present at much higher concentrations indoors. Indoor VOCs may come from many sources including cleaning products, air fresheners, and new furniture. They can harmful to health on their own, or serve as precursors for the formation of aerosol particles.
– You have probably heard about secondhand smoke, which is the exposure of non-smokers by being around smokers. Thirdhand smoke can also be a problem. This occurs when nicotine, tar, and other harmful chemicals in tobacco smoke deposit on indoor surfaces like walls and carpets. People can be directly exposed to these chemicals through contact the surface, or reactions with gases like ozone may cause them to re-enter the gas phase.
We are looking forward to the warmer weather and more time in the fresh air outdoors!
El Dr. Mario Molina es un químico conocido por todo el mundo por su trabajo en la química atmosférica. El Dr. Molina ganó el Premio Nobel de Química en 1995 por sus investigaciones sobre la descomposición del ozono estratosférico. Más recientemente, él ha estado trabajando para entender y mejorar la calidad del aire de la Ciudad de México y otras ciudades grandes, al iqual que el cambio climático. En el 2005 se fundó este Centro, que es “un puente de soluciones prácticas entre la ciencia y las políticas públicas en materia de energía y del medio ambiente para promover el desarrollo sustentable.”
These materials were developed by Profs. Pratim Biswas, of Washington University St. Louis, and C. Y. Wu, of University of Florida, through a collaborative grant from the National Science Foundation. The modules are aimed at an introductory college level, and are excellent for supplementing course materials or learning on your own.

Next week (Oct. 12-14) is Earth Sciences Week. This is a great opportunity to get to know the educational programs offered by NASA. Our favorite is “S’COOL.” In this program, you learn about the different types of clouds, and you can make observations of the clouds in your area, record them, and report them back to NASA. By doing this, you can help NASA validate the performance of the CERES satellite. This satellite observes the same clouds you see from the ground, but from space!

Nuestro programa favorito es “S’COOL.” En este programa, se aprende sobre los diferentes tipos de nubes, y se pueden hacer observaciones de las mismas en su área, registrarlas, y reportarlas a la NASA. De esta manera, se puede ayudar a la NASA a verificar la funcionalidad del satélite CERES. Este satélite observa las mismas nubes que se pueden ver desde el puto de vista terrestre, al igual que desde el espacio!
