Current Sea Level Rise is Faster Than at Any Time in Last 6,000 Years

Current Sea Level Rise is Faster Than at Any Time in Last 6,000 Years | Garry Rogers | Scoop.it

(NASA satellite shot of Antarctica on October 13 of 2014. Recent scientific papers point toward a vicious cycle of Antarctic glacial melt. Expanding sea ice results from increased cold, fresh water outflows from melting land-anchored glaciers spreading out along the ocean surface and protecting the floating ice. Meanwhile, rapidly warming waters concentrate in a layer beneath the ice to further accelerate melting of the giant glaciers’ bases. Image source: LANCE-MODIS.)

Garry Rogers's insight:

GR:  Clearly, we are changing Earth’s climate at an unprecedented rate. It’s hard to predict how this will change human society. The possibilities are discussed in the next post from xraymike79. Important reading.

China Is Selling Off Vital Panda Habitat To The Highest Bidder

China Is Selling Off Vital Panda Habitat To The Highest Bidder | Garry Rogers | Scoop.it

Melissa Cronin:  "There are an estimated 1,600 pandas left in the wild in China, and thanks to new legislation, that number may change very soon — for the worse.

"The Chinese government is currently in the midst of introducing its "forest tenure reform" legislation in several provinces. Originally introduced in 2008, the new reforms were meant to stimulate local economic benefits reaped by people living in forest communities.

But in effect, the reforms could allow for the sale of some 694,884 square miles of critical old-growth forest for commercial logging, firewood collection and development. The area, currently owned collectively by villagers, represents 15 percent of China’s panda forests, according to a new study published in the journal Conservation Letters."


Garry Rogers's insight:

GR:  Fifteen percent doesn't seem to severe, but relinquishing habitat at this rate would lead to loss of protection for all Panda habitat in seven years.  Land-use planning must always take a long-term view.  Some planners recommend 200-year projections to allow estimates of the effects of small changes.


This is a story that we should follow.  The habitat involved supports many more species than just Pandas.

Turning to Darwin to Solve the Mystery of Invasive Species

Turning to Darwin to Solve the Mystery of Invasive Species | Garry Rogers | Scoop.it
A new study suggests that some parts of the world are evolutionary incubators, producing superior competitors primed to thrive in other environments.
Garry Rogers's insight:

GR:  The research described in this article is a fine confirmation of familiar ideas. I was gobsmacked by the implication that it contained new ideas.  Invasions occur when species with well-developed ruderal traits are treated to human dispersal, disturbed ecosystems, few direct competitors, and no disease organisms. Perhaps the editor of Global Ecology and Biogeography needs to ask if the reviewers were qualified.

Saving Caribbean Coral Reefs

Wildlife decline: Why does biodiversity matter anyway? - Christian Science Monitor

Wildlife decline: Why does biodiversity matter anyway? - Christian Science Monitor | Garry Rogers | Scoop.it
Half of the planet's wildlife populations suffered severe decline between 1970 and 2010, according to a new report from the WWF. So what does dwindling biodiversity mean for us?
Garry Rogers's insight:

As biodiversity declines, the Earth's carrying capacity, its ability to produce renewable resources, declines. Scientists are already telling us that the growing human population has exceeded the Earth's carrying capacity.  What motivates our leaders to continue with development and "progress" when they surely know what is happening? What should we do?

We must all take responsibility for combating climate change.
Garry Rogers's insight:

This will not happen. First, the few that profit from the industries causing the problems feel insulated and protected from the consequences.  Second, the governments and political leaders hope the wealthy will give them enough of the wealth to achieve the same protection.

The Ghost in the GMO Machine - Cascadia TimesCascadia Times | Garry Rogers | Scoop.it

While independent research shows that Chlorpyrifos, a Dow Chemical insecticide used in Kaua‘i’s GMO fields, can cause significant harm to children nearby, Dow is intent on convincing the EPA otherwise.

Garry Rogers's insight:

GR:  Of course, other species are harmed as well, making it unacceptable to use these pesticides and the GMOs bred for compatibility.  About 40 years ago, we switched our course from controlling population to supporting its continued growth.  Thus, we encouraged the research that has produced the GMOs. By following this path, we abandoned any hope of preserving healthy ecosystems.  Now over half of our wild animals are gone, and we continue along on the road to massive extinctions and destruction of Earth ecosystems.

Office of the Auditor General of Canada—Mitigating Climate Change | Garry Rogers | Scoop.it

Overall, we found that federal departments have made unsatisfactory progress in each of the four areas examined. Despite some advances since our 2012 audit, timelines for putting measures in place to reduce greenhouse gas emissions have not been met and departments are not yet able to assess whether measures in place are reducing emissions as expected.

Garry Rogers's insight:

GR:  So, the 15th largest world economy has succumbed to greed and has placed profit above the health of the land.

Ocean Acidification: The Complete Loss of Tropical Coral Reefs By 2050 to 2100

Ocean Acidification:  The Complete Loss of Tropical Coral Reefs By 2050 to 2100 | Garry Rogers | Scoop.it
GR: This post is about CO2 and ocean acidification. Other blog posts about plastic in the oceans, overfishing, garbage dumping, and toxic runoff suggest that the cost of the human impact on oceans will be far greater than the trillion dollars estimated by the UN Convention on Biological Diversity. Those costs are based on short-term factors. Species extinction is permanent. Recovery of biodiversity will take millennia. Some would say that causing the loss of a single species is unacceptable. So once again, I have to say that we must push harder. Sign those petitions, take time for the rallies and marches, send letters, make phone calls, join local groups, and enter local politics.

What do you think is the most effective strategy to combat this trend?

Flooding Risk From Climate Change, Country by Country

Flooding Risk From Climate Change, Country by Country | Garry Rogers | Scoop.it
A new analysis of sea levels and flood risk around the world offers more evidence that the brunt of climate change will not be borne equally.


More than a quarter of Vietnam’s residents live in areas likely to be subject to regular floods by the end of the century.  Globally, eight of the 10 large countries most at risk are in Asia.  These figures are the result of a new analysis of sea levels and flood risk around the world, conducted by Climate Central and based on more detailed sea-level data than has previously been available.  The analysis offers more evidence that the countries emitting the most carbon aren’t necessarily the ones that will bear the brunt of climate change.

Garry Rogers's insight:

My first reaction to this story was that it is the kind of news that would motivate our leaders to take action to stop greenhouse emissions that are responsible for climate change.  Then it occurred to me that the 98% will pay for the cost of rising sea level. It will have no impact on the 2% and the congress they control. The only solution that comes to mind is divestiture, but even that feels weak.  Got any ideas?

Human Impact: Artificial Light Disrupts Sex Hormones of Birds

Human Impact: Artificial Light Disrupts Sex Hormones of Birds | Garry Rogers | Scoop.it
Under light at night, something gets broken and you see a dampening of the hormonal system.
Garry Rogers's insight:

Artificial light contributes to wildlife decline. Harmful human impacts also come from habitat loss, invasive species, toxic waste, pesticides, hunting, livestock grazing, water diversion, logging, mining, hiking, sound, and more. The growing impact of our seven billion mouths to feed and seats to sit overwhelms every little improvement we make. For a well-documented survey, I recommend Goudie’s “The Human Impact.”
