Climate change thanks to jets spraying
I am a scientist and it's about time to talk about the planes that are spraying our skies. The planes are dropping aluminum barium and in Oregon our water is measuring 60 parts per billion. That is happening all over the world. Try to find a lab that can dectect it? Almost impossible. Save your water and test it then spread the word and please help me save our planet.
Better than
Farmer almanac, while it isn’t always perfect it is fairly accurate. More so than Al Gore.

I too asked a question about inaccurate predictions. But never got a reply.
Predicted Snowfall for Bend and Sunriver this winter?
Looking more for predicted snow fall patterns going into November-December 2018 and into the New Year. Is there a way to get this prediction here or somewhere? Not just looking for rainfall patterns, specifically snow. Thanks,
Not so good
August was waaaayyyyyy off. How certain can we be about this coming winter's precipitation? Isn't there an El Nino brewing?
Way off mark...
Mid-Willamette Valley in Oregon.... Hot, hot, hot....
No cool and sunny weather -- so far this August. No showers...
Though we might dip down from 96F to 78F in a couple of days. "Might".... if the weather predictions at Accuweather are correct.
Rain
We have gotten some rain here in Eastern Klamath county, we will have to wait and see about the snow.
Cool
Cool and sunny on coast, all ?summer?
warmer summers
You address warmer Arctic conditions and the ocean temperatures effect on the jet stream, etc. And yes, most importantly we are all in this together. The geo-engineering has an effect on our weather (and your predictions) also. What are your thoughts on geo engineering and are you able to factor it into your weather predictions?
Weather Forecasts
Thank you for your question! It’s a good one. While we do not factor in geo-engineering directly, we do take into account the last 30 years of available climate data, which would account for any short-term changes in climate due to geo-engineering. Additionally, because our forecasts are only for the following year, the effects of geo-engineering and other man-made factors that are currently occurring may not be visible for many years.
