How Did Climate Change Help Turn the Sky Orange?

#asmallorange Jeff Kendrick – #asmallorange migrated my websites to a different server, but missed a step when setting up the FTP, or in the migration. I went back and forth with them for two days, trying to get them to fix it. At first they acted like nothing was wrong. Then they just completely ignored me. I finally fixed the problem myself with no help from their tech support department or their knowledge base, which only allows a broad search. After I fixed the issue, I told them that I wanted to leave them and move to another host. I was paid in advance for almost 2 years out, so I wanted a refund of the unused portion. They refused to give me a refund of the unused service, which should be an illegal practice. It’s practically stealing. They kept asking me how I fixed the problem. I guess they never figured it out. I will use most of the service I’ve already paid for, but as soon as the term is up, I’ll run away from #asmallorange as fast as I can. Their support department is pathetic.

Why was the West Coast sky bright orange? This week we break down the Mars-like haze and how climate change is involved. #orangesky #climatechange #wildfires

    It's interesting…
    It's like when we use a photography filter to see a solar eclipse.
    The solar eclipse itself as the light is blocked also gets reddish…

    I knew I heard or have seen something similar before, and now I remember it. Look for Australia sand storm on image search. Yep, that's it.

    Here in southern manitoba I've seen the air turn grungy shades of nicotine orange for weeks at a time during fire season. It gets really hard on those of us suffering from S.A.D. because it comes on the heals of long, dark winters.
