Signs of Change

There's news, but then there's news that affects us all, which we have a front row viewing from around the world.  By drilling ice cores and analyzing the air bubbles, scientists have found that at no point, during at least the past 800,000 years have atmospheric CO2 levels been as high as they are now.  That will explain your nice garden and thick trees with heavy leaves; last fall was the most leaves I've ever seen on the ground, this year will be the same, the vegetative growth is vigorous.

Going further back in time during the Ordovician Period some 488.3 million years ago the sun would have been several percent dimmer according to established nuclear models of main sequence stars, our sun gets brighter and hotter as she ages.  We know CO2 was probably very high coming into the late Ordovician Period but with a dimmer sun we see a dip in Earth's C02 instead of runaway greenhouse effect, the planet slumped into a glaciation period.  Unlike other glaciations in the last 500 million years, this one lasting perhaps only a million years or so but the main reason for generating so much interest recently is because it took place when CO2 levels were apparently sky-high.  High CO2 is necessary to stop the Earth from freezing over, many elements in climate change take place, from our sun, the magnetic field around Earth, gasses, land mass exposed, Earth's tilt, atmosphere, oceans and ice all play a role in climate change.

Signs of Change series from HawkkeyDavis Channel does not mean the world is ending! These are documentaries of a series of extreme weather events which are leading to bigger Earth changes, every changing planet, got Gore-Tex?

Not only the inhabitants' unrest around the world but the planet itself seems to be revolting.  The stability of the West Antarctic Ice Sheet is an issue of active research and societal concern because of the potential economic impact resulting from an increase in global sea level.  The West Antarctic Ice Sheet, riddled with deep crevasses and flowing ice streams, contains over 700,000 cubic miles (3 million cubic kilometers) of ice.  Since the peak of the last ice age nearly 20,000 years ago, the West Antarctic ice sheet has lost nearly 2/3 of its mass – a volume sufficient to raise sea level 33 feet.  

From HawkkeyDavisChannel:

The earthquake uptick continues all over the ring of fire.  At the center of these changes, the United States deals with historic flooding which was nearly a one-in-500 year event!

So much more has taken place the month or so than this video shows.  The deluge continues to hit heavily populated areas!  Be prepared for large scale disasters in your area. It has and it will continue to worsen whether we like it or not.  Stay safe and thanks for watching!

This should be the last of the monthly installments of this series.  Look for them a little more often!  (end HawkkeyDavisChannel)

On April 28, 2014, a powerful tornado passed through Louisville, Mississippi.  The ISS SERVIR Environmental Research and Visualization System (ISERV) on the International Space Station captured this photograph showing damaged vegetation and debris left behind by the storm.  ISERV acquired the image on May 4, 2014.

The tornado left a scar 58 kilometers (36 miles) long and up to 1.3 kilometers (0.8 miles) wide.  With winds that topped 297 kilometers (185 miles), the storm was rated an EF4 on the enhanced Fujita scale.  Ten residents of Winston County died as a result of the storm.

At least nine tornadoes hit Mississippi that day, including EF3 tornadoes in Tupelo and Richland.  The tornadoes were part of a larger weather pattern that produced about 79 tornadoes from Nebraska to North Carolina between April 27–29.  On May 2, the Earth-Observing 1 satellite captured a similar image of tornado damage in Mayflower, Arkansas.
