Terrarism and the Terrarists

Tar Pit #3

Terrarism, terrarists and terracide: words coined on the TomDispatch blog to refer to the the men who run what may be the most profitable corporations on the planet: giant energy companies like ExxonMobil, Chevron, ConocoPhillips, BP, and Shell.

It’s time to talk bluntly about the terrarists of our world.  Yes, I know, 9/11 was horrific  ... and the Boston Marathon bombings weren’t pretty either.  But in both cases, those who committed the acts paid for or will pay for their crimes.

In the case of the terrarists ... you’re the one who’s going to pay, especially your children and grandchildren. You can take one thing for granted: not a single terrarist will ever go to jail, and yet they certainly knew what they were doing.

Beginner’s Guide to the Sixth Mass Extinction

sixth-great-extinction-poster-crop-052213Not sure what we mean by the Sixth Mass Extinction? What were the other five? Is there really a sixth one going on? Will we all disappear like the dinosaurs? Is this real science or just a Sixth Mass Anxiety Attack?

For a simple explanation, check out the Sixth Mass Extinction blog by Hannah Boyne. It offers a easy-to-read explanation of each of the five previous known extinction events:

Questions from a High School Student

high-school-052113A high school student who's giving a presentation to her class about sport hunting asked if I'd be up for answering some brief questions on the topic.

Here are her questions and my answers. The questions range beyond hunting, and I pulled no punches in responding. After all, today's teenagers are going to be dealing with the mess that we and other generations are bequeathing to them, so the more they know about the state of the Earth and the sooner they know it, the better equipped they'll be to mitigate the damage and adapt to the consequences.

Greenhouse Gases Just Gone Through the Roof

planet-earth-051313

Last week, the amount of carbon dioxide in the atmosphere went through the roof. Another roof.

The previous roof was 350 parts per million (ppm) – which was generally considered to be the point of no return, beyond which it would be very hard to stop a runaway climate effect from happening. We went through that roof about 25 years ago. And last week, according to the National Oceanic and Atmospheric Administration (NOAA).the amount of CO2 in the atmosphere topped 400 ppm.

No human being has ever witnessed greenhouse gases at this level. Scientists say the last time Planet Earth was like this was probably about 2 million years ago, during the Pleistocene Era.

How Humans Can Survive. (Should We?)

Al Dixon of Granby checks on his colonies of honey bees. Dixon says he has lost nearly two-thirds of his colonies over the winter. Colony Collapse Disorder caused the decline. Stephen D. Cannerelli / The Post-Standard</p><br /><br />
<p>Newsweek leads off this week with an article about the future of humankind.

It opens with how the bees are dying off and the enormous toll this is going to take on our food supply. (Note to author: It will also take quite a toll on the bees.)

It proceeds with a description of what it means to be in the early stages of a mass extinction. And it concludes with the exhortation that "we must take control of the Earth."

U.K. Astronomer Royal: Is This Our Final Century?

Britain’s Astronomer Royal is setting up an organization to study the risks posed to ourselves and our planet by modern technology.

“Nature has value in its own right,” he says. “So it’s imperative to do what we can to preserve the natural world, and this has to go beyond any human self-interest.”

Take note, fellow humans: What we do to the koalas' homes we're ultimately doing to our own home.

(This little person's home was demolished in Australia's Vittorio State Forest. He was later taken to another koala colony.)

Earth Day – Still All About Us

earth-day-1-042213

There’s something almost a little hubristic about our celebration of “Earth Day.” As though we generously give the Earth a day each year –  and the rest of the year belongs to humans.

As Ocean Rises, Kiribati Islands Plan to Evacuate

submerged-gas-station-kiribati-041513
The remains of a gas station submerged as the waters rise over Kiribati.

The President of Kiribati calls it "migration with dignity." The ocean is rising. Fresh water wells are filling with sea water. Dead people can no longer be buried. The nation's government sees no way out.

The nation of Kiribati (pronounced Kirr-i-bas) comprises 33 islands along the Pacific equator. Once a British protectorate, It was fought over during World War II by the Americans and Japanese. Some of their armor still sits on the beaches.

Today, the invasion comes from the ocean – and it actually is the ocean. Kiribati is going under.

Israel, Palestine, Peace and Water

This morning, President Obama spoke clearly to the Israeli people about why they should seek peace with their neighbors, the Palestinians. He talked about the need for security, about the demographics that necessitate a two-state solution, and about how continued prosperity depends on peace with their neighbors.

There was one more he could have added – the one that could screw every nation in the Middle East: water.

Comet Heading for Mars

mars-comet-2014-030613

In the wake of the asteroid fly-by two weeks ago, and the meteorite that slammed into Russia the same day, we now hear that Mars might possibly be hit by a comet next year.

Comet C/2013 A1 (Siding Spring) was spotted for the first time two months ago, and astronomers have now calculated that it will be within striking distance of Mars in mid-October 2014. But will it actually score a direct hit?

Right now the comet is a long way away, and ice cold. But as it enters the inner Solar System, it will start to warm up and chunks of ice and meteors will start to break away, forming a classic comet coma. If Mars passes through the coma, a huge meteor shower will rain down on it.

Another option is that these changes in the comet will alter its orbit – maybe moving it a bit further away from the planet ... or, indeed, a bit closer. Which gives it a real chance of actually crashing.

If that happens, Mars will be hit by an object 20 miles wide or more, traveling at 120,000 miles an hour. On his Bad Astronomy blog, Phil Plait writes:

Doing a rough calculation, I get an explosive yield of roughly one billion megatons: That’s a million billion tons of TNT exploding. Or, if you prefer, an explosion about 25 million times larger than the largest nuclear weapon ever tested on Earth.

Watch out, Mars rover "Curiosity"!

A Day at Yosemite

One day, 30 videographers, nine kinds of cameras, 14 minutes of video.

Produced by Steve Bumgardner, a former park ranger who, he says, spends his time "roaming the mountains looking for untold stories about the natural and human world."

David Attenborough’s Swan Song?

attenborough-1-012313The indefatigable David Attenborough is back on PBS's Nature Tonight with the three-part series "Attenborough's Life Stories", which looks back over his 60 years of film making.

So you might think this is his swan song. And maybe it is. Except that on the same day, across the pond in the U.K., he's launching yet another new series, "Natural Curiosities", which he describes as "interesting stories about interesting animals." One might add: "by an interesting person."

After the Sixth Extinction

This smiling fellow, known as Thalattoarchon saurophagis, was cruising the oceans about 244 million years ago in what are now the mountains of central Nevada, snapping up smaller fish for dinner. And that, we’re told, is good news. Here’s why.

On the End of the World

A few months ago, a friend of mine, Janet, asked me if I thought the world would really end on December 21st. I asked her why she would be more concerned with a supposed “Mayan apocalypse” than with the much more down-to-earth reality that we’ve entered a time of growing ecological disaster.

“It’s easier to imagine the Mayan apocalypse,” Janet said. “After all, you know it’s imaginary, like zombie apocalypses and all that good stuff, so it takes your mind off the real thing.”

Don’t Bet on a Climate Agreement in Qatar

Lots of luck trying to get the nations of the world to do anything meaningful about our rapidly warming planet. As the talks in Qatar enter their second week, nobody's expecting much to come of it all.

The basic agenda of most of the nations is to see how little they can do and how much they can get away with. China, which emits more greenhouses gases than the next three biggest polluters combined (the U.S., India and Russia) insists that it is a "developing" nation and should be exempt from any agreements. India takes the same position.

As a result, Russia, Japan and Canada are pulling out of the Kyoto Protocol that was signed by 191 states and took effect in 2005, saying it's meaningless to set new targets when China and India are not bound by it. The United States never signed it in the first place. Europe is split over what to do about extending the Kyoto agreement. And other nations aren't sure what to do.

The only way out of the crisis is to "throw everything we have at the problem."

Developing nations want wealthier countries to pay them to cut greenhouse gases. But most of those wealthier countries say they don't have the money any longer and have to cut their budgets at home.

Meanwhile, greenhouse gas pollution was up 3 percent last year. Together, the world's nations combined pumped nearly 38.2 billion tons of carbon dioxide into the air from the burning of fossil fuels such as coal and oil, according to calculations published yesterday in the journal Nature Climate Change.

That's about a billion tons more than the previous year – or more than 2.4 million pounds of carbon dioxide every second.

Three years ago, nearly 200 nations set the goal of keeping global warming to 2 degrees C (3.6 F) in this century. But the World Bank has already warned that the world is now likely to warm by up to twice that amount by the end of the century.

Glen Peters, lead author of the new study said that the only way out of the crisis is to start drastically reducing world emissions now and "throw everything we have at the problem."

Given the "you go first" attitude of just about everyone present in Qatar this week, that seems unlikely.
