The Earth Day Flag created by John McConnell

The celebrated astrophysicist, Neil deGrasse Tyson, said, “People never look up.” Tyson or Starman, as he is called, is right. Look up and you’ll see amazing stuff: puffy cumulonimbus clouds rising 60,000 feet, broken rainbows, blue skies bluer than blue, Venus and Mars huddling beside the new moon, the Milky Way.

When you look up, you can’t help realize you are standing, feet firmly planted, on planet Earth. We are attached in a very physical way to this place...this planet called Earth.

So, not only look up, but, as Rachel Carson declared in many of her writings, “Look around, and down, and closer.”

Whether you are looking up or looking down, we celebrate our home planet every year on April 22. This celebration or “birthday” is called Earth Day and it has been going on since 1970 after Gaylord Nelson, a U.S. Senator from Wisconsin, proposed a day of national focus on environmental issues. Buoyed by the success of Rachel Carson’s book Silent Spring, about the concern for living organisms and the environment, Earth Day 1970 set out to raise public awareness for the health and harmony of the planet. People from all walks of life— young and old, farmers and urban dwellers, liberals and conservatives— banded together and achieved great things. The first Earth Day on April 22, 1970 led to the creation of the United States Environmental Protection Agency and the passage of the Clean Air Act, the Clean Water Act, and the Endangered Species Act.

And now, forty-six years later, Earth Day 2016 has gone truly global. Around the world, people celebrate Earth Day with massive rallies, marches and festivals. But for many people it is not just an annual event, but all the quiet acts and the simple habits performed throughout the year. For instance, I make it a habit of recycling every piece of plastic I use (or as much as humanly possible). Less plastic that ends up in the oceans means happier and healthier sea turtles and whales.

If you want some ideas about how you can demonstrate your support for environmental protection, you might start by checking out the book, Recycle This Book - 100 Top Children’s Book Authors Tell You How To Go Green.

And if you link to the Earth Day website, you can take a peek at all the great activities planned around the world on April 22, 2018.

Let’s make this the best Earth Day ever...all year long!

With essays from renowned children’s book authors such as Ann Brashares, Jeanne DuPrau, Caroline B. Cooney, Laurie Halse Anderson, Bruce Coville, Gennifer Choldenko, and more than 100 others, each piece is an informative and inspiring call to kids of all ages to understand what’s happening to the environment, and to take action in saving our world. Helpful tips and facts are interspersed throughout.

Part of the award-winning Scientists in the Field book series, Sea Turtle Scientist introduces Dr. Kimberly Stewart, “the turtle lady,” and describes her work on St. Kitts with endangered loggerhead sea turtles. The book provides extensive information on sea turtles and Dr. Stewart’s research, as well as the efforts of WIDECAST to preserve and protect these amazing creatures.

Climate Change: The Facts and the Consequences

No one can honestly deny that our climate has been changing in recent years. Before the winter of 2018-2019, California had only a year’s water supply stored in its reservoirs. Wildfires have become an annual threat throughout much of the west, while the Midwest and East Coast have experienced record-setting winters. These problems are due to complex interactions among temperature, winds, and water currents.

A major change is the warming of the atmosphere. The earth’s atmosphere has been getting warmer since the late 1800s, when factories started spewing out carbon dioxide. Because natural variations also affect the temperature, a graph showing the temperature over time is a jagged line. But the trend is consistently upward and follows the graph of increasing carbon dioxide in the atmosphere due to human activities. That’s strong enough evidence that we are at least a large part of the problem, and the vast majority of climate scientists are urging countries of the world to reduce their carbon dioxide emissions.

A major player in the world’s weather is the jet stream, which helps circulate the atmosphere around the world about every two weeks. This flow of fast-moving air speeds across North America from west to east, separating cold arctic air from warmer, more southerly air. The jet stream used to run in a fairly direct arc across the northern United States. But in recent years it has become less stable, dipping southward in the eastern U.S. to bring frigid winters to the Northeast while arching northward in the West, carrying warm, dry air there. Scientists believe that the rapid melting of the Arctic ice brought about by global warming is part of the cause for the jet stream’s instability.  However, climate trends are controlled more by the oceans. Scientists estimate 95% of the heat from global warming is being stored in the oceans, increasing water temperatures even into the depths.

As global warming continues, so will climate change. The melting of sea ice and glaciers is already raising the sea level. While scientists don’t blame climate change for devastating Hurricane Sandy, Sandy’s extreme coastal flooding was made worse by the increase in sea level that’s already occurred. As time goes on, coastal cities around the world will be at increasing risk for more severe storm damage.

Because warm air holds more moisture than cold air, storms are becoming more severe, increasing blizzards and flooding storms. Some agricultural regions that depend on reliable rainfall may soon be unable to grow crops, disrupting the food supply.

Climate change is complicated, but because it affects us all, we need to learn about it.  The Environment Protection Agency has questions and answers about climate change.

Oceans cover 71% of the Earth’s surface and contain 97% of the water on our planet. This chart shows how this water has absorbed the vast majority of the increased atmospheric heat due to global warming.

This chart shows how carbon dioxide in the atmosphere has increased since 1960. The measurements are made near the top of Mauna Loa on the island of Hawaii, thousands of miles away from any land-based major pollution.

Calculations of global warming prepared in or before 2001 from a range of climate models. The projections assume no action is taken to reduce emissions.

Yellowstone National Park’s majestic geologic wonders and remarkable wildlife draw millions of visitors each year. But there was a time when these natural treasures were in great danger, all because after years of unrestricted hunting, one key piece of the puzzle had been eliminated—the wolf.

Now, more than a decade after scientists realized the wolves’ essential role and returned them to Yellowstone, the park’s natural balance is gradually being restored. Dorothy Hinshaw Patent's text supplemented by spectacular full-color photographs show the wolves in the natural habitat that was almost lost without them. Click here to find out more.
