Here Are the American Experts - 208

 

Here is NASA’s Climate Websites:

“It’s not your imagination: Certain extreme events, like heat waves, are happening more often and becoming more intense. But what role are humans playing in Earth’s extreme weather and climate event makeover? Scientists are finding clear human fingerprints.”

“Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

“From more frequent and longer heat waves to more intense rainstorms, scientists are increasingly confident human-induced climate change is making some types of extreme weather and climate events much more likely.”

Off NOAA’s website:

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause Earth to warm in response.” The United States' foremost scientific agencies and organizations have recognized global warming as a human-caused problem that should be addressed. The US Global Change Research Program has published a series of scientific reports documenting the causes and impacts of global climate change. NOAA, NASA, the National Science Foundation, the National Research Council, and the Environmental Protection Agency have all published reports and fact sheets stating that Earth is warming mainly due to the increase in human-produced heat-trapping gases.

On their climate home page, the National Academies of Sciences, Engineering, and Medicines says, "Scientists have known for some time, from multiple lines of evidence, that humans are changing Earth’s climate, primarily through greenhouse gas emissions," and that "Climate change is increasingly affecting people’s lives."

Legacy

Legacy is the masterpiece of Yann Artur-Bertrand. It is a must watch 1 hour and 41-minute documentary offered on Amazon Prime. (Prime is available for free on a one-month trial basis.) Inspired by his love of nature and humanity Bertrand has taken the wisdom attained through 50 years of observing nature and employed his mastery of film to give us a spellbinding history of earth and man. At this critical juncture in man’s ascent, it is his passion, a grandfather’s passion to protect his grandchildren, which drives him to excel at 76. If we look back to the days of Leonardo De Vinci or Michelangelo these geniuses had a very small audience with whom to communicate, to make a positive impression, and to create change. They communicated primarily with the aristocracy and the clergy.   There was no need to influence the masses since the common man was not involved in decision making. Commoners could not even read or write. Democracy has widened the base of decision making. By voting ...

Your Hero: Plato or Joe the Plumber?

My appreciation for the plumber came to me from opposite directions. As a semi-successful do-it-yourself plumber, I slowly learned a bit about the trade. I learned that when the sewer starts to backup plumbers should be reached by dialing 911.   Sorry Plato, you lose round one. But, what about the history of plumbing and its importance to human civilization? Plumbing history came to me accidentally.    While employed by the Military Sealift Command, I was “stuck” on the Island of Crete. Being stuck on Crete is not a hardship. In fact, you might pray that you suffer this fate one day. Before docking, I read in National Geographic, about an ancient civilization on Crete called the Minoan. In its heyday, young nimble girls would leap over charging bulls at festivals. In a way it was like modern Olympic gymnastics springboard competition between the horns. The article said there were frescos on preserved walls of the ancient Palace of Knossos depicting the event. ...

Becoming Wise Gardeners

Often, when we talk about saving the earth’s climate we talk about the number one problem, the need to switch energy sources from polluting and archaic fossil fuels to modern clean energy sources. More so, I enjoy reading and learning about the second simultaneous step we need to take to save the climate. Some of the Carbon Dioxide must be removed from the air and stored. Scientists use the terms Carbon Capture and Sequestration (CCS), or Carbon Capture and Utilization (CCU) to describe this. When carbon is captured it must be used or safely put somewhere. Today it is pumped back into the earth into old mines or oil fields. These mines and oil fields are called “sinks”. Mother Nature has a lot of natural sinks. For instance, I am sitting in my favorite rocking chair listening to music. My chair and my speakers are made of wood. Alive, or dead, a tree and its commercial product timber, are natural carbon sinks. In fact, any plant is a carbon sink. Far and away the best carbon sink...
