Turn Out the Lights
So, last week we learned that half of the human race can no longer see the stars of the Milky Way. Now we learn that someday soon the summer will devoid of the lights of the firefly. We seem content to destroy all that is
beautiful and wondrous about the natural world.
Blink and you’ll miss
them this summer. Around the world, people are reporting that local firefly
populations are shrinking or even disappearing.
The insect’s dilemma
first came to the world’s attention at the 2010 International Firefly
Symposium, where researchers from 13 nations presented evidence of firefly
population declines and declared “an urgent need for conservation of their
habitats.” Since then, additional conferences and several scientific papers
have documented regional firefly disappearances, and at least two
citizen-science projects are attempting to document the phenomenon, but the
full scope of the problem remains to be uncovered, says firefly researcher Ben
Pfeiffer, founder of Firefly.org, a
website about the decline of the insects, also called lightning bugs.
The loss of fireflies,
which are actually beetles, can have multiple effects on their ecosystems. For
one thing, some firefly species—there are at least 170 in the U.S.—play a role
in pollination. They’re not as essential as bees, but they help pollinate
milkweed, goldenrod, wild sunflowers, and other species.
More important,
however, firefly larvae are voracious predators that live in the ground and eat
slugs, snails, worms, aphids, and other problem critters that would otherwise
grow out of control. “I call them nature’s pest control,” Pfeiffer said. (On
the other side of the dinner table, fireflies are also important food sources
for species such as bats and spiders.)
Climate Changes Clouds
One effect of climate change is to shift the pattern of clouds both away from the mid-latitudes and higher above the earth. The result of that climate change driven
shift is more warming which drives even more extreme climate events. It’s a loop folks and we need to stop it.
The distribution of
clouds all across the Earth has shifted...
And moreover, it has
shifted in such a way — by expanding subtropical dry zones, located between
around 20 and 30 degrees latitude in both hemispheres, and by raising cloud
tops — as to make global warming worse.
“As global warming
occurs, there’s the expectation that the storm track will shift closer to the
pole and the dry areas of the subtropics will expand poleward,” said Joel
Norris, a climate scientist at the Scripps Institution of Oceanography at the
University of California, San Diego, and the study’s lead author. The work was conducted with scientists at Scripps, the
University of California at Riverside, Lawrence Livermore National Laboratory
and Colorado State University.
Not just one but both
of these changes to clouds are “positive feedbacks” to climate change — tending
to make warming worse.
Moving cloud tracks
toward the poles enhances warming because at higher latitudes, less solar
radiation strikes the Earth — so white clouds are reflecting less of it away
from the planet than they would if they were closer to the tropics and the
Equator, Norris said. Meanwhile, he continued, higher cloud tops in effect
thicken the total column of cloud, and that means more trapping of infrared or
heat radiation that would otherwise exit to space.
Trump Could End the World (as we know it)
Is there anyone who doesn’t think Donald Trump would be a climate catastrophe? Yesterday,
we pointed out that U.K. prime ministerial hopeful Andrea Leadsom was close to the most egregious climate deniers in the U.S. And, now she’s out of contention for the
prime minister job. Let’s see if it
works on Trump.
To prevent climate
change that floods large portions of coastal cities, dooms small island nations
and turns whole regions into deserts, we need to accelerate the transformation
of the world’s energy economy away from fossil fuels. Those who have crunched
the numbers say this can still be achieved, but just barely. Hitting the brakes
would send us over the cliff.
Over we go if Donald
Trump wins the election and carries through on his campaign promises. The
effects on the global climate will persist not only for the four or eight years
of his presidency, but for generations.
Barack Obama’s fight
against climate change centers on a plan to reduce the use of coal (the largest
source of US greenhouse gas emissions). Trump has vowed to cancel this plan,
somehow revive the US coal industry and support domestic production of oil and
natural gas.
He hasn’t been overtly
hostile to solar, another major source, but the plummeting price (and hence
growing competitiveness) of solar are largely driven by low-cost panels from
China. Trump’s promised trade wars could end the days of cheap solar here.
If the US – historically
the world’s largest emitter, with high per capita emissions – refuses to act,
and if it withdraws from the Paris agreement and reneges on its pledge to help
developing countries deal with climate change (as Trump has also promised to
do), the leaders of India and other developing countries will face great
political pressure at home to follow the easy path of using more coal.
Yes, More About Dogs (and conservation)
Namibia has the largest population of cheetahs in
Africa. As every apex predator, the
cheetah is under incredible pressure. In
Namibia there is a vast array of programs and organizations working to protect
cheetahs, while also protecting farmers whose herds are victims of cheetah
predation. Of course, dogs can help.
Cheetahs, the fastest
land animals on Earth, have been disappearing almost as fast as they can run.
But in the African
country of Namibia, the cheetah population has grown from 2,500 to 4,000 since
1994. And dogs are helping to keep those numbers rising.
Instead of trapping or
shooting cheetahs that wander onto their property and kill livestock, some
farmers are relying on Anatolian Shepherds and their fierce barking to scare
away the predators.
“You may see in
history that this dog can be responsible for saving the cheetah from
extinction,” Jack Hanna, director emeritus of the Columbus Zoo, told CBS News.
“That is one heck of a story right there.”
You can help put more dogs to work in Namibia or contribute
to other projects that are helping to protect and preserve cheetahs here.
CCF’s renowned
Livestock Guarding Dog Program has been highly effective at reducing predation
rates and thereby reducing the inclination by farmers to trap or shoot
cheetahs. CCF breeds Anatolian shepherd and Kangal dogs, breeds that for
millennia have guarded small livestock against wolves and bears in Turkey. The
dogs are placed with Namibian farmers as puppies. They bond with the herd and
us their imposing presence and loud bark to scare away potential predators.
Guard dogCCF has been
placing dogs since 1994 and our research shows the dogs are highly effective,
reducing livestock loss from all predators by over 80 and up to 100 percent.
Farmers adopt CCF dogs and participate in education on how to train the dog.
CCF does on site follow up visits to ensure the dogs have proper training and
medical care, and are settling into their guardian role. Farmers have
enthusiastically embraced the program, and there is now a two year waiting list
for puppies. CCF had placed nearly 500 dogs by the end of 2013. CCF research shows
that the people’s attitudes towards predators are changing as a result of this
and other CCF programs.
Pure Blind Hate
Hatred of wolves is part of the DNA of many ranchers and politicians in the American West. The Department of the interior walks a fine
line supporting both wolves and ranchers.
And it is always the wolves that suffer in the end.
The investigation by
the Department of Interior Office of the Inspector General, expected to be made
public today, substantiates many of the allegations made by Catron County in a
2013 complaint – namely that the service protected “genetically valuable”
wolves in the wild, even after they preyed on cattle, did not tell residents
when wolves were near and did not fully compensate ranchers for cattle killed
by wolves.
Ranchers in the area
have long been against the reintroductions that began in 1998, since they are
prone to losing livestock to wolf depredations. The report substantiates claims
that ranchers were not fully compensated for their losses during the former
coordinator’s tenure.
“Most said that they
received compensation for only a small percentage of the cattle they lost,” the
report said, adding that ranchers blame the difficulty of confirming that a
missing or dead animal has been killed by a wolf as well as unresponsiveness
and past interference in investigations by the field office.
To these ranchers and politicians no coexistence is possible, so when Federal officials tend to protect the wolves, they get slapped down. While, it remains open season on wolves.
Wildlife officials are
investigating the deaths of three Mexican gray wolves.
Authorities say one
wolf was found in New Mexico and another two in Arizona but they’re not
releasing details.
It’s another blow to
the wolf reintroduction program run by the U-S Fish and Wildlife Service along
with state agencies.
Over the years that
program has been plagued by legal battles and illegal wolf killings.
