Chemtrails

Careful what you wish for....I'm going to assume you were being facetious.

Living at the beach in San Diego

I live at the beach in So Cal too. We don’t notice the heat changes because of the glorious Ocean breezes and reliable climate. I work from home and ride my bicycle to do all my errands... EASY to think in a bubble.
However, one mile inland is a whole different story for folks. Think about it. Inlanders have been suffering higher and longer periods of intense heat for some years now. Climate change, however created, It is very real.

As well, I fully join you in capturing rainwater !! Hello! Free water! Cistern! Anyone?

Climate Change

You are in one specific area and claim to speak for the entire world. Also, you say sea level is not rising. What is that based on? Your eyes? Well your eyes are not exactly scientifically accurate.

What are your credentials? Climate change is real and so is the fact that much of it is caused by US humans. Look to the polar ice caps, the evidence is all around you. There is solid consensus among scientists about climate change.

How dumb is that

Sea level is not going up, i can see it for myself ... dumbest statement ever. Let me just say this.. the day you can see sea level risen this earth we call home would be long gone!!!

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.

Polar ice caps? Is that your

Polar ice caps? Is that your scientific proof? Nothing will stay frozen forever. Temperatures are rising because as the ice melts, like it has been doing since its formation, the total mass of ice becomes less, therefore, temperatures rise. This is basic physics. I learned these principles in elementary school. Cause and effect...

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.

Chem not con

Correction - chem trails are silver or aluminum nano particles

Con trails are condensation trails due to the pressures around the wing of a plane.
