About GarryRogers

Dr. Garry Rogers is a biogeographer with interests in natural landscapes, vegetation ecology, and nature conservation. He agrees with the logic of the ecocentric view that all of nature, the atmosphere, biosphere, geosphere, and hydrosphere, has intrinsic (inherent) value.

The decline of journalism in the mainstream media

Corporate control over news media is a symptom of the end times (or something that is as bad as that sounds).

Independent media: Our democracy depends on it, Independent Australia.  Cathy McQueen “………It is hard to open a newspaper of the mainstream media (MSM) or indeed watch a television “report” today without seeing content littered with the journalistic opinion of the person writing or reporting it — even if it purports to be “straight” news.

I hate to think of what Keating would think of the Australian MSM now. We have a good 70 per cent of it — the Murdoch press — that only publishes far-right propaganda most of the time and blatant lies the rest of the time.

The remainder of the MSM does its best to do their jobs – I am talking Fairfax and The Guardianand the ABC – but even they are not immune from serving the far-right agenda of…

Switch to Renewable Energy

GR–Ode to concerned scientists: They see the danger, they sound the horns and clang the bells, and they wait. But the ramparts remain empty. They turn to their family and friends, but dreamlike their voices are too soft and none respond.

“Fifteen thousand scientists have issued a dire warning to humanity about impending collapse but virtually no-one takes notice. Ultimately, our global systems, which are designed for perpetual growth, need to be fundamentally restructured to avoid the worst-case outcome.

“For a moment, the most important news in the entire world flashed across the media like a shooting star in the night sky. Then it was gone. In November, over fifteen thousand scientists from 184 countries issued a dire warning to humanity. Because of our overconsumption of the world’s resources, they declared, we are facing “widespread misery and catastrophic biodiversity loss.” They warned that time is running out: “Soon it will be too late to shift course away from our failing trajectory.”

“This is not the first such notice. Twenty-five years ago, in 1992, 1,700 scientists (including the majority of living Nobel laureates) sent a similarly worded warning to governmental leaders around the world. In ringing tones, they called for a recognition of the earth’s fragility and a new ethic arising from the realization that “we all have but one lifeboat.”

“This second warning contains a series of charts showing how utterly the world’s leaders ignored what they were told twenty-five years earlier. Whether it’s CO2 emissions, temperature change, ocean dead zones, freshwater resources, vertebrate species, or total forest cover, the grim charts virtually all point in the same dismal direction, indicating continued momentum toward doomsday. The chart for marine catch shows something even scarier: in 1996, the catch peaked at 130 million tonnes and in spite of massively increased industrial fishing, it’s been declining ever since—a harbinger of the kind of overshoot that unsustainable exploitation threatens across the board.” –Jeremy Lent (What Will It Really Take to Avoid Collapse?).

How Many of You Switched to Renewable Energy?

In recent posts, I described the warnings of impending disaster. I didn’t expect to have an impact, and I wasn’t wrong. As Jeremy Lint points out in the article above, the media avoidance of unappetizing topics is too complete. And of course, our leaders in power avoid the subject in their subservience to wealth. My first hint that good advice for avoiding collapse would be futile was the minimal response to my discovery of the simple and inexpensive means for everyone to switch their homes from fossil fuel energy to renewable energy. Like Pangloss, I’ve remained hopeful. But I read that book, and now I’ve turned to a more practical concern; the post-anthropocene survivors, the weeds, have absorbed my attention. Today’s weed is Shepherdspurse, a foreign but familiar little mustard that feeds butterflies and yields medicines for us humans.

How Bird-Friendly Are Your Windows?

Bird-Friendly Windows

It’s our responsibility to take care of all animals on this planet, to protect them from harm and keep them from extinction. With that in mind, we need to pay a little more attention to the windows we’re installing both on high-rise buildings and in our homes. Astonishingly, around 1,000,000,000 birds die every year in the United States as they unwittingly fly into the windows of our man-made structures.

Despite that not all birds die on impact, many of them eventually perish regardless; a devastating result of the internal damage, bleeding and brain trauma caused by the collision. The fear is that a number of species, such as the Wood Thrush, Painted Bunting, Warbler, Kentucky Warbler and the Worm-eating Warbler are at risk of becoming extinct if the problem persists.

The good news, however, is that a number of materials and tricks we can use to alert birds to the oncoming danger of a transparent or reflective surface:

1. Angled Glass

2. Fritted Glass

3. Etched or Sandblasted Glass

4. UV-reflective Glass

5. Decals and wind chimes

6. External shutters, including Venetian blinds

7. Tape Strips

8. All-season bug screens

9. External shades and awnings

10. The whitewashing of unused windows

GR: Moving from theoretical to practical, an article in Nature reports on the use of observed global warming to choose the best models for predicting future global warming. Future warming is normally estimated by combining several models. In the new research, the scientists found that the best models actually predict a warmer future than the combined models did. National commitments to reduce emissions have to increase.

“Greater future global warming inferred from Earth’s recent energy budget”

Abstract:  “Climate models provide the principal means of projecting global warming over the remainder of the twenty-first century but modelled estimates of warming vary by a factor of approximately two even under the same radiative forcing scenarios. Across-model relationships between currently observable attributes of the climate system and the simulated magnitude of future warming have the potential to inform projections. Here we show that robust across-model relationships exist between the global spatial patterns of several fundamental attributes of Earth’s top-of-atmosphere energy budget and the magnitude of projected global warming. When we constrain the model projections with observations, we obtain greater means and narrower ranges of future global warming across the major radiative forcing scenarios, in general. In particular, we find that the observationally informed warming projection for the end of the twenty-first century for the steepest radiative forcing scenario is about 15 per cent warmer (+0.5 degrees Celsius) with a reduction of about a third in the two-standard-deviation spread (−1.2 degrees Celsius) relative to the raw model projections reported by the Intergovernmental Panel on Climate Change. Our results suggest that achieving any given global temperature stabilization target will require steeper greenhouse gas emissions reductions than previously calculated.” –Brown and Caldeira.
