Climate change
We they say man made climate change what they really mean is military industrial complex geoengineering. If they don't
stop soon we are all screwed. If it's not already to late.
Rain in Northern California
Holy mackerel! This is the driest fall/winter I’ve seen for a very long time. I’m afraid we are in big trouble with our lack of rain. The animals, forrest and Human survival depends on rain. Can’t they ‘chem-trail’ clouds that will produce rain here?! They’re doing the trails anyway. Why not HELP us all out?! Any answer on this would be appreciated. It’s doable- it’s been proven!
Rain and Water
Be prepared for paying much more for water in the future. I like to keep everything green, unlike many of my neighbors who have let all landscaping just die--GROSS, and such an eyesore!! If you do not want to pay for water--just move to a place where it is just hot and dry and only cactus, rocks, and tumbleweeds! I am a San Diego native, and I have just bcome accustomed to the fact, the weather is changing-- hotter and drier. I wish others would just accept this sad fact--and stop allowing everything to just die all around them, waiting for rain!
Chem-trail
I think you are confusing “chem-trail” for cloud seeding. Chem-trails are water vapors reacting with the heat and chemical exhaust from the airplane’s engine, while cloud seeding is the dispersion of silver iodide or dry ice in the air to affect change in the clouds to produce more rain in a specific region.
Hey y'all! El nino or el Nina really going to hit San Diego?
Ok I'm a weather junkie! I love crazy weather I hate how sunny it is in San Diego! My question is......... do we have a el nino really coming up? Like I need rain!

No rain in the valley
No rain in October and we're now in November I live in Modesto California and it hasn't rained I'm kind of worried. My question is, is the government messing with our weather? Or are we going through major climate change? It seems to me like the whole world is changing and not for the good
Any rain between Nov 28th and
Any rain between Nov 28th and Dec 4th for Los Angeles/Hollywood area ?
The weather and climate change
Our weather is normal cycling. We’ve had several ice ages. For 5 billion years we’ve had cycles. Don’t buy in to all the hysteria. You’ll be dead and long forgotten before humanity is challenged by weather changes.
