Coal Plants And Fish
High levels of an element found in coal ash have been detected in fish in two lakes where Duke Energy coal-fired power plants are located, according to a peer-reviewed study at Duke University. The element, selenium, occurs naturally but is concentrated in coal ash.
Bleached And Dying
Climate change is posing a major threat to the future of coral reefs. According to a recent United Nations-backed study, if swift action is not taken to curb greenhouse gas emissions, annual coral bleaching events will affect nearly all of the world’s coral reefs. And coral bleaching can result in serious coral mortality – as Australia’s Great Barrier Reef has recently illustrated.
Saving Saharan Oases
An oasis is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source such as a pond or a small lake. Oases can provide habitat for animals as well as people. Oases have long been essential for trade and transportation routes in desert areas; caravans typically travel via oases so that supplies of water and food can be replenished.
Fish On The Move
As the oceans warm, many kinds of fish are on the move, seeking cooler and deeper water. Because of this, the fishing industry is struggling with antiquated regulations that are not moving as fast as the climate is changing.
Storing Energy In An Old Mine
An abandoned, centuries-old iron mine in the Adirondacks about 100 miles north of Albany, New York may become the site of a new hydroelectric energy storage system. The mine in the tiny hamlet of Mineville near Moriah, New York contributed iron for the first naval battle of the Revolutionary War that took place on Lake Champlain. The mine hasn’t been used in over 45 years.
The Great Salt Lake Is Shrinking
Utah’s Great Salt Lake is the largest salt water lake in the Western Hemisphere and is the largest body of water in the United States after the five Great Lakes. When the pioneers first arrived in the area back in the middle of the 19th century, the lake spread across about 1,600 square miles. Now, the lake covers an area of only about 1,050 square miles, a reduction of about 35%.
Fracking And Earthquakes
Hydraulic fracturing, or fracking, is the process in which water, chemicals and sand are injected at high pressure to split apart rock thousands of feet below Earth’s surface and release oil or natural gas. And it’s a controversial practice.
Rising East Coast Seas
Sea levels are rising around the world because of melting ice as well as warming waters since water expands as its temperature goes up. Average sea levels around the world are predicted to rise by about three feet by the end of the century as a consequence of the warming climate.
China As Climate Leader
China and the United States today produce nearly half of the world’s carbon emissions, so the fight against global climate change depends greatly upon what actions the two countries take. China has undergone a dramatic transformation over the past twenty years from a largely rural society to one that is far more urbanized and far more energy intensive. In 1997, when the Kyoto Protocol on climate was negotiated, China was only responsible for 14% of global CO2 emissions. It then surpassed the US on that front in less than 10 years and now accounts for nearly 30% of the world’s emissions.
Turning Carbon Dioxide Into Rock
There is a lot of interest in figuring out a way to store carbon dioxide produced from industrial processes and energy plants or even sucking it out of the atmosphere and then storing it. The problem is where exactly to put the stuff and how to make sure that it stays there.
Hot Times For Santa
Santa Claus may have to change out of that heavy red suit this Christmas. The North Pole, site of his fabled workshop, is seeing historically high temperatures this year. In fact, it is 36 degrees Fahrenheit higher than it has been in past decades. This is a staggering number.
Help Save The Bees
Globally, 40% of invertebrate pollinator species, such as bees and butterflies, are facing extinction. And since approximately three-quarters of the world’s food crops depend on pollination, the decline of these pollinators could pose a threat to food security around the globe.
The Zombieless Apocalypse
Post-apocalyptic fiction is all the rage these days. There are numerous stories featuring an endless list of civilization-ending disasters: asteroid collisions, cataclysmic earthquakes, nuclear wars, supervolcanoes, pandemics… the list goes on and on. Most of the time, humanity either perishes entirely, is reduced to a handful of heroic and astonishingly resourceful souls, or ends up inexplicably as zombies staggering around the landscape in search of brains.
Turning Sunlight into Fuel
When looking at the best ways to meet humanity’s energy needs, there is little doubt that the sun is the ultimate answer. In one hour, the Earth receives enough energy from the sun to meet all of our needs for a year. Despite this fact, the world currently only gets about 1% of its energy directly from the sun.
Improving Wave Energy
Ocean energy is still one of the biggest untapped clean energy sources on the planet. There are many studies that have shown that it could provide power for millions of homes in the U.S. alone. But despite this, the technology is still in its infancy and it is unclear when and if it can become a major contributor to our energy needs.
Wave Energy In The United States
By some estimates, America’s oceans could provide enough electric power to meet a quarter of the country’s energy needs. Despite this, until recently the contribution to the U.S. electric grid from marine energy has been exactly zero.
Offshore Wind At Last
Europe has embraced offshore wind power as a major contributor to its electricity needs for a long time. As of June, there was a total of 3,344 offshore wind turbines with a combined capacity of over 11.5 gigawatts of power connected in European waters in 82 wind farms located in 11 different countries and providing power to millions of people.
A Water Superpower
In 2008, Israel was on the verge of catastrophe. A decade-long drought in the Fertile Crescent of the Middle East was scorching the area. Israel’s largest source of fresh water, the Sea of Galilee, had dropped to within inches of the so-called black line at which point irreversible salt infiltration would flood the lake and ruin it forever.
