Human Impacts on the Environment

Imagine aliens land on Earth a million years from now. What will these curious searchers find of us? They will find what geologists, scientists, and other experts are increasingly calling the Anthropocene, or new age of mankind. David Biello explains how the impacts that humans have made have become so pervasive, profound, and permanent that some geologists believe we merit our own epoch.

French President Macron Gives US Congress A Vital Lesson in Responsibility

French President Emmanuel Macron again on Wednesday (4-26-18) brought up the double-C word — climate change —  during an address to Congress, taking aim at the Trump agenda and the U.S. president's decision to pull out of the Paris climate accord. "By polluting the oceans, not mitigating CO2 emissions and destroying our biodiversity we are killing our planet," he said during an address to Congress. "Let us face it, there is no planet B.”

Merchants of Doubt: What Climate Deniers Learned from Big Tobacco

In March 2015, Robert Kenner, the Director of "Food Inc" and other acclaimed documentaries, will debut his newest, "Merchants of Doubt". Based on the book by Naomi Oreskes and Eric Conway, the film follows the development of sophisticated methods for distorting science, used by the Tobacco industry to hide the poisonous nature of their products, and adapted by the Fossil Fuel industry to distort the science around climate change.

Tesla’s solar + Powerpack project in Kauai

Kauai Island’s KIUC electric utility cooperative’s transition to Solar+Wind+ Batteries holds the promise of greater reliability, lower operating costs, and cheaper clean energy for consumers. KIUC also represents Hawaii’s first island community on its way to 100% power self-sufficiency, with the added community bonus of producing Zero emissions and pollutants going into the local environment from power plants.

Will Renewable Energy Ever Replace Fossil Fuel? YES.

Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges. Lesson by Federico Rosei and Renzo Rosei, directed by Giulia Martinelli.

Why People Don’t Believe In Climate Science

Scientists overwhelmingly agree that our climate is changing, Earth is getting warmer, sea levels are rising, and it's primarily because of humans putting lots of carbon dioxide in the atmosphere. Yet 4 in 10 Americans aren't convinced Here's what psychologists and sociologists have to say about why some people don't believe in climate science.

The Arctic Meltdown is a huge problem for all of us

The Arctic is in the throes of what sea-ice scientist Peter Wadhams called a “death spiral.” As the region’s once abundant ice melts, giving way to a less reflective surface, the Arctic heats up faster — now at a rate that is double the rest of the planet.

Polar meltdown and the polar jet stream connection -- a river of wind that travels around the Northern hemisphere.

Artic MeldownThe air in the north wants to flow to the south, where the layer of air is hotter and thicker (hot air expands). The now-warmer Arctic makes it so there’s less of a pressure difference, so what once was a mountain in the sky becomes a gentle hill.  Like a river moving down a soft incline, the jet stream moves more slowly and more erratically.In the United States, these changes in the jet stream are linked to a persistent “ridge” — like a hump in the sky. This causes weather patterns to linger, “perpetuating drought, heatwaves, and extensive wildfires across much of western North America,” according to the report.This phenomenon, according to the NOAA report, brought a “parade of destructive nor’easters along the eastern seaboard” in the winters of 2013-14 and 2017-18. Most notably, it led to what has been dubbed the “bomb cyclone,” an intense blizzard along the East Coast in January 2018.The same phenomenon is also responsible for so-called "Atmospheric Blocking" which produces all kind of severe weather, including the slower, more intense hurricanes we’ve seen of late. Harvey and Florence, which hovered over the mainland SE coast for days and dumped trillions of gallons of water, were dangerously stuck in place thanks to a “block.”

Greenland has always been known for its glaciers. Currently the glaciers in Greenland are in trouble and are melting unprecedentedly fast. aerial footage as well as research experiments clearly show that the ice is disappearing far too quickly to be any sort of normal climatic change.

Guy McPherson – “How Do We Act in the Face of Climate Chaos?”

The rate of climate change clearly has gone beyond linear, as indicated by the presence of myriad self-reinforcing feedback loops, and now threatens our species with extinction in the near term. Anthropologist Louise Leakey ponders our near-term demise in her 5 July 2013 assessment at Huffington Post. In the face of near-term human extinction, most Americans view the threat as distant and irrelevant, as illustrated by a 22 April 2013 article in the Washington Post based on poll results that echo the long-held sentiment that elected officials should be focused on the industrial economy, not faraway minor nuisances such as climate change.

Climate change: Earth’s giant game of Tetris

There's a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide -- a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels that run our cars, factories and power plants. Joss Fong outlines how this overload of CO2 leads to climate change and reminds us that, unlike Tetris, we won't get an opportunity to start over and try again.
