Global warming & chem trails

Thanks for broaching the subject Lorri Ann!
Global warming was not caused by man. We can shut down everything and it will continue to get hotter. Even if humans had never existed, it would happen. It's part of the process of our planet and its place in the solar system.
To all those who blame humans - if that were true, global emissions would have been completely haulted by now.
Someone IS trying to buy us time with chem trails. Others are working on getting us into space in large numbers and colonizing Mars. Elin Musk is not alone in this. Yes, the chem trails are toxic and the side effects unpredictable but when imminent death is at hand, those things aren't really issues.
The planet is going through one of its regular periods of shift. It will be catastrophic to all life on Earth. We can join in the efforts to flee the planet or we can take life, day by day, with gratitude for every moment and love and dance and laugh and fully live in every moment we have left.

Global Warming

Yes, you are correct. The real deal is how we are going to get off of the planet. We are essentially " running out of time ".

Global warming and Chem Trails Gloom & Doom?

I live in the Pacific Northwest in a rural area just north of the California/Oregon Border. Chem trails have been an issue in our communities for years as our cancer rates, miscarriage and birth defects in both people and cattle steadily rise beyond the limits of National Averages so, if you think playing God with the weather it s helping anything, anyone or any source of life, you’re delusional. Since when did interfering with the laws of nature result in anything one could remotely call good??? If you know anything’s no about environmental history and mans obsession with “being in control” then you know this earth is not of our creation nor does it belong to anyone regardless of deeds, borders, claims of ownership are simply more proof of mans ignorance and arrogance. It is man who is to blame for the environmental disasters and senseless deaths that are a direct result of mans constructs yet, there is no dooms day awaiting is around the next corner. Only the hand of life can take any life and the operative word here is “take”... I am saddened by the tone in your post mind surrender and helplessness. The only impossibility is in your own mind and I have to say, why is it you prefer such a mindset?
Global warming not the work of man??? Ummm, have you ever heard of the ozone layer?? Man and his careless inventions all for the sake of convenience hold sole responsibility for what is happening to this lovely blue planet and it is mans refusal to own that and make the sacrifices of creature comforts that is to blame for where we are headed. If you can’t be part of the solution, please at least don’t be part of the problem! I’m not resigning my great grandchildren’s planet cuz I’m too lazy to do whatever it takes to heal our planet, our lives and our futures!

Global warming

Yes I agree. In one of our news paper ( Oregon ) said that it is a matter of time the earth will flip. The north is not the true north it is changing faster then plan.

Spot On

Absolutely! Spot on Josie! Sitting here enjoying life every second I have air in my lungs.

Chemical Trails theory

The government mindlessly flies big jet airplanes over my area constantly from a local Air Force Base for no apparent reason I do believe that they are unmanned drones. If the CO2 accumulation in the atmosphere is becoming a problem then why do they continue to mindlessly fly these big airplanes in the sky constantly all the time even at night. Chemtrails are not made up by people who wear tinfoil hats the proof is the truth and that they do spray this skies with different products including aerosols and sulfur dioxide temporary block out the sunlight to cool the planet. There are currently a lot of inventions being promoted to reduce the Greenhouse Effect and some of them are not logical some of them are. The way it is is very expensive yet we cannot temporarily cool down the planet not knowing the feedback loop of what will happen after the cooling subsides and we have a runaway greenhouse effect. Yes the Earth does change naturally though no time ever recorded have we ever burned so many fossil fuels that the accumulation of methane CO2 and other nitrous oxides and such are at an alarming rate due to the industrial population explosion. When volcanoes erupt they emit a lot of different stuff such as sulfur dioxide which temporarily does create a Ice Age if it is a big enough eruption to block the sunlight out for days, weeks, months and even years. The 1% of people who have more money than all of the 99% are the ones behind trying to fix the climate crisis that we are currently producing man-made climate change.

Chem trails theory

Why do people continue to to the wrong thing......GREED BASED PERSONAL PREFRENCES. The same reason why industries have been moved overseas and poverty and incarceration has increased here in the US. Greedy people push for business as usual to maintain profits and don’t care about environmental or social impact. Why would anyone think that the government would do the right thing?

Feb 5-13 Weather Conditions

The prediction for Weather Conditions during the period of Feb 5-13th didn't age well.

Dictionary

The dictionary says this for contrails: a trail of condensed water from an aircraft or rocket at high altitude, seen as a white streak against the sky.
The dictionary says this for chemtrails: a visible trail left in the sky by an aircraft and believed by some to consist of chemical or biological agents released as part of a covert operation.

Chemtrails

Chemtrails are a conspiracy theory made up by tinfoil hat wearing plebs. The same people who believe in ' crisis actors ' and lizard people.
