A History of Earth’s Climate

Earth had a climate long before we showed up and started noticing it and it’s influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we’re gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we’re experiencing now is different than anything this planet has encountered before. So, let’s take a stroll down Climate History Lane and see if we can find some answers to a question that’s been bugging Hank a lot lately – just how much hot water are we in?

Beautiful strange and rare cloud formations

Even though different cloud formations might seem random and indescribable to you, there’s a whole cloud classification system that’s uniform worldwide.

Stunning storms super-cells photos by Mike Hollingshead (30 pictures)

Mike Hollingshead said about homself that he’s “just a guy that liked storms as a kid then started chasing them in 1999. Bought a still camera in 2002. Quit my job in 2004, with zero intentions beyond simply chasing that spring, then getting a job somewhere again that summer. At least 8 years later now I’ve still not gotten that job. Somehow this just happened and has worked. It was never a plan to do this, it just happened. I’d have chased every year all the same, but it being my soul income was the furthest thing from my mind. And heck, it’s only barely worked(debt) the whole time. It’s a long story, but more or less it’s not nearly as great as it sounds. There’s no peace of mind in hoping sales come along and your old hobby sometimes feeling as if you have to do well at it. I could write a book on this topic now. For every up about it there is a solid down.”

Why the sky ISN’T blue

On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red? To answer these questions, we must learn about light, and the Earth’s atmosphere.
