Destroying the Most Persistent Scientific Myth In America

If anyone tells you that the warming we’ve seen over the past century is just a natural swing in Earth’s temperature, they are wrong. Absolutely and totally wrong.This widespread myth is a favorite of some politicians, but It’s been proven WRONG, and there is no scientific doubt about it. I’ve talked about this before and shown graphs etc. but Bloomberg Business did an excellent html web page that shows just

Because we know little about hurricane behavior during periods when Earth was warmer or colder than at present, it’s challenging to construct models to predict future trends in hurricane activity as Earth’s climate changes. To remedy this problem, researchers have been working to reconstruct records of hurricane strikes in the

  “The greenhouse effect” often gets a bad reputation because of its association with global warming, but the reality is we can not live without it. What causes greenhouse effect? Life on earth depends on the energy of the sun. Approximately 30 percent of the sunlight that beams toward Earth deflected by the outer atmosphere […] The post What Causes of the Greenhouse Effect? appeared first on Liberty, Equality, and

Our sun is a volatile star: explosions of light, energy and solar materials regularly dot its surface. Sometimes an eruption is so large it hurls magnetized material into space, sending out clouds that can pass by Earth's own magnetic fields, where the interactions can affect electronics on satellites, GPS communications or even utility grids on the

Hutton (June 3, 1726 - March 26, 1797) is considered to be the father of modern geology. He is accredited with proposing that observed geologic processes have been occurring at a uniform rate since the creation of earth, also know as the theory of unconformities. This led to his controversial suggestion that the earth is incredibly old. Hutton began to notice geologic processes on his land

In case you missed it, Part 2 addressed a big question:  Are we oxygen breathers important to life on Earth, with respect to life, happiness, temperature, and gas ratios?   The answer is a resounding NO!  But we just couldn't leave all those yummy plants lying around.  :) Obviously, when we are talking tiny percentages, we moderns can screw things up with ddt, plastic, and ozone poison

The highest energy thing we have going here is the rotation of the Earth, followed by the radiation heat deep in the Mantle.  I don't know how many atomic bombs they are, or how many seconds of the Sun, but it is huge.  Man isn't even the flea on these elephants.  The orbit of the Moon is somewhere there, and that controls the tides. For the rotation, two things leech off it - ocean

There is a lonely nondescript mountain of limestone in the barren desert east of Death Valley National Park. There is a hole at the base of the slope, the entrance to a cavern. Lurking within are prisoners, creatures that have been trapped in the cave for perhaps 20,000 years or more. They are mutants, no longer the same as their cousins who live freely just a few miles away. They are alone

To continue, in the Earth, with regard to available heat energy, the oceans are the dog, and the atmosphere is the fluff on the end of the tail.  In the atmosphere, water vapour is the dog, and carbon is maybe one hair on the tail. It not enough to merely state the energy ratios, one must also make a statement on stability and sensitivity.  If Roxie stood super still, and on high alert, then

This week’s Imaggeo on Mondays image is brought to you by Cyril Mayaud, from the University of Graz (Austria), who writes about an impressive hike and layers of cold and warm air. Thermal inversion is a meteorological phenomenon which occurs when a layer of cold air is trapped near the Earth’s surface by an overlying layer of warmer air. This can happen frequently at the boundary between mountainous and lowland regions such as in Slovenia and last for weeks, obscuring the sun from view to [...]

Use a candle and a piece of card to model the evidence of the movement of a tectonic plate over a fixed heat source in the Earth’s mantle.

I remember very well watching the CBS Evening News 35 years ago on the first Earth Day. It was a major story, and I believe Walter Cronkite led the broadcast with it. We know a lot more about our planet now than we did then, and there have been some amazing successes in protecting our environment. We now know something that was not well understood then, and that is the
