Biggest Hoax Ever Perpetrated on the American People

A few months ago, I was talking to a friend (a physical therapist) when the question of climate change arose. She said it was “the biggest hoax ever perpetrated on the American people.” I don’t think I asked why just Americans, and not the whole world. It’s probably just as well.

Greenhouse Effect? Well, No. Not Really

As we spoke, I asked if she understood how the greenhouse effect works. She didn’t. In fact, she hadn’t really thought about it before.

This is beyond my understanding.

I’ve never understood this phenomenon. How can somebody be so certain of something he or she knows nothing about?

This is just a short video (4:09). It can’t tell you everything you need to know about climate change, but the Science Guy packs a lot into four minutes.

See It Here

I can’t embed this video, but it’s worth clicking here to see it. While you’re there, read the short article, too. It’s very basic stuff, but stuff an awful lot of people (included educated ones) don’t seem to know.

Climate change is real, and it’s bad.

Climate change is real, folks. We are causing it. It’s terribly important. And no, this is not just one of the natural changes the planet cycles through every few thousand years. Bill Nye the Science Guy explains why climate change is much more than a buzzword. “It’s a real and serious issue,” he says.

  • Contrary to what you probably keep hearing, ten of the last 13 years were the hottest on record worldwide.
  • With 92% of the year gone, 2015 is on course to be the hottest year ever recorded.
  • The planet’s overall temperature has increased 1.2 to 1.4 degrees Fahrenheit over the past century. That may seem like a small amount, but most of that increase has been in the last few years. In other words, the world is getting hotter faster.
  • A very substantial amount of the excess carbon dioxide in the air is dissolving in the planet’s oceans, lakes, rivers, and streams, turning them into acid. This is already beginning to dissolve the shells of clams, oysters, and other shellfish. Who knows how many species will eventually disappear from the waters because of this?
  • Rising seawater is ALREADY threatening several small island nations.
  • And 97 percent of climate scientists worldwide say this potential and real devastation has been caused by human activity.

Start here with Climate Change 101, but don’t stop here. This is just the stuff every 6th grader ought to understand, but most adults don’t. An educated adult ought to know far more about it than what you’ll see here. Watch this blog for more from time to time.

Samantha Says “Change Climate Change”

I believe her.
Astronaut Samantha Christoforetti wants to "Change Climate Change."
Astronaut Samantha Christoforetti wants to “Change Climate Change.”

Samantha Cristoforetti, born in Milan in 1977, boarded the International Space Station on November 23, 2014, becoming became the first Italian woman in space. She wants to “Change Climate Change.”

She was a US foreign exchange student attending Space Camp when she was 18. Now she has a degree in mechanical engineering from the Technical University of Munich, and has studied in France and Russia and graduated in Aeronautics Sciences at the Italian Accademia Aeronautica in Pozzuoli, becoming a lieutenant and fighter pilot in the Italian Air Force. Besides all that, she speaks five languages.

We Must Change Climate Change

I’ve shown her here to discuss her message: Change Climate Change.

No matter what your friends tell you, or your politicians, or even the doctor in your group who likes to think of himself as a scientist … and no matter what you want to believe, climate change is both real and dangerous; and we are causing it. The physics is well understood and the satellites monitoring the planet’s temperature show the lower atmosphere is warmer almost every year that ever before.

Those of us alive now won’t see the worst effects  of it, but our children and grandchildren and their grandchildren will. And it won’t be fun.

We need to change climate change now.

400 ppm Carbon Dioxide

400ppm Carbon Dioxide
400ppm Carbon Dioxide

I copied this tweet from Former Vice President Al Gore a few minutes ago. I don’t have the resources to quickly verify it; but I know it is approximately true. And generally, I accept the VP’s facts as true (always pending verification, of course), whether or not I always agree with his opinions and interpretations.

We know the carbon dioxide concentration in the air has been increasing for around 200 years, and even longer to some extent. If there are actually 400 parts per million (ppm) of it in the air now, this is a huge 60% increase from the 250 ppm or so 200 years ago.

But won’t green plants take it back out? After all, that’s what they do. Green plants take carbon diode out of the air and convert it to sugars to energize the plants.

Unfortunately, we are putting carbon dioxide into the air faster than plants can take it out. Until we make some serious changes in the way we live, we’ll just keep on adding carbon dioxide to the air faster than it can be removed. This means the concentration will go up and up and up.

Since carbon dioxide is a greenhouse gas (We need to discuss what that means soon.), it will tend to increase global temperatures and create changes in our climates. That is happening now.

Eventually, it will change the chemistry of the oceans in extremely detrimental ways.We don’t know how soon that will be. It is probably already happening.

Eventually, though it will not be really soon, the carbon dioxide we keep on putting into the atmosphere will choke our civilization and destroy it. We don’t want that, so we need to find ways now, as a society, to stop putting so much carbon dioxide into the air.

Thanks, Bill and Steve

Thanks to Bill Moyers and Steve Mirsky for letting us know about this guy.

How can an ignoramus like this get elected to Congress? Much less become Chairman of the Science Subcommittee on Oversight of  the House Committee on Science, Space, and Technology? He doesn’t understand the science he is supposed to regulate. He thinks it is “lies from the pit of hell.”

I first read about Paul Broun in Scientific American, December2012, Antigravity, by Steve Mirsky. He was in this position then, and he still is. As well as being a member of several other important committees.

Surely the State of Georgia can do better than to let this man run un-opposed again. Get him out of the House of Representatives and back into medical practice where he can only hurt one person at a time.

On second thought, he ought to have his license to practice medicine revoked, too. Do you really want a doctor who thinks that much of what he was taught in medical school is “straight from the pit of hell”? Including not just evolution and cosmology, but embryology, too?

And if Georgia won’t stop electing him, isn’t there at least some way to get him off any science-related committees?
