Permafrost Melting releasing Methane

December 23, 2019

As climate change melts Alaska’s permafrost, roads sink, bridges tilt and greenhouse gases release

Alaska’s permafrost is under assault from a warming climate, and it’s happening a lot faster than anticipated. Hillside slopes have liquefied, unleashing slides that end up as muddy deltas in salmon streams. The ground under the Nome airport runway—key to linking the community to the outside world—has thawed, requiring costly patches. And during the hottest July on record, a sinkhole 14 feet deep opened along a main roadway in the city.

Climate Change Predictions from 1951 and 1958

For a region where climate change also is bringing profound changes offshore, these are disruptive developments. As the northern Bering Sea warms, bird and marine mammal die-offs are on the rise and winter ice is on the decline, enabling storms to gain strength over open water and slam into coastal communities like Teller.

The accelerating melt is a global concern: Permafrost, which mostly lies in the northern reaches of the planet, is a vast carbon storehouse of frozen plants and animals that release greenhouse gases as they warm and decompose.

Fossil fuel combustion still is the main source of greenhouse gas emissions driving climate change. But the world’s permafrost now releases 1.2 to 2.2 million metric tons each year—at the upper end, nearly equal to Japan’s greenhouse gas emissions, according to a report this month by the National Oceanic and Atmospheric Administration. Later this century, these emissions are expected to exceed those of the United States.

Scientists who study permafrost already are noticing some striking changes in Alaska’s landscape.

Canadian scientist Merritt Turetsky monitors tracts of interior Alaska permafrost that a decade ago were covered by spruce forest. That land is now covered with lakes.

Destruction of the Environment as the Consequence of Overpopulation

Top News Headline – Control Population to Save the Planet

November 5, 2019

If I drive on the road, can I go 120 MPH wherever I want?

If I owned a gun, can I have any weapon and unlimited ammo?

Everything needs some form of limit or control, otherwise the world

would be a lawless planet.  Everything in moderation, right?

Why should someone be allowed to have 10 children if the world is already overpopulated?  Can someone argue that they NEED to have 10 kids?

The earth does need fewer people. But no one has to die or be killed.  We just need reasonable limits on family sizes.  No one “accidentally” had 10 kids.

In the last 40 years, the human population doubled.  You know what didn’t double?  The size of our planet.

Cause, effect.

Man Made Climate Change predicted in 2000 year old scrolls

“And consequently the weather will break down, and alternating severe cold and heat and much flooding will rule, and death will come a thousandfold over the human beings, the plants and animals, and over the creatures and over the Earth, as a result of the irrationally unleashed forces (Gewalt) of the human beings who live in too large of numbers (overpopulation) and in wantonness (greed) for might, addictions, and vices, thus bringing destruction unto the end of the world (all around the whole world).

Humanity’s emissions ‘100-times greater’ than volcanoes

October 1, 2019

Human activity churns out up to 100 times more planet-warming carbon each year as all the volcanoes on Earth, says a decade-long study released Tuesday.

The Deep Carbon Observatory (DCO), a 500-strong international team of scientists, released a series of papers outlining how carbon is stored, emitted and reabsorbed by natural and manmade processes.

They found that manmade carbon dioxide emissions drastically outstrip the contribution of volcanoes—which belch out gas and are often fingered as a major climate change contributor—to current warming rates.

The findings, published in the journal Elements, showed just two-tenths of 1 percent of Earth’s total carbon—around 43,500 gigatonnes—is above the surface in oceans, the land, and in our atmosphere.

The rest—a staggering 1.85 billion gigatonnes—is stored in our planet’s crust, mantle and core, providing scientists with clues as to how Earth formed billions of years ago.

One gigatonne is equivalent to around 3 million Boeing 747s.

By measuring the prominence of certain carbon isotopes in rock samples around the world, the DCO were able to create a timeline stretching back 500 million years to map how carbon moved between land, sea and air.

They found that in general the planet self-regulated atmospheric levels of carbon dioxide, a key greenhouse gas, over geological timeframes of hundreds of thousands of years.

The exceptions to this came in the form of “catastrophic disturbances” to Earth’s carbon cycle, such as immense volcanic eruptions or the meteor strike that killed off the dinosaurs.

“In the past we see that these big carbon inputs to the atmosphere cause warming, cause huge changes in both the composition of the ocean and the availability of oxygen,” said Marie Edmonds, Professor of Volcanology and Petrology and Ron Oxburgh Fellow in Earth Sciences at Queens’ College, Cambridge.

The team estimated that the Chicxulub impact 66 million years ago, which killed off three-quarters of all life on Earth, released between 425 and 1,400 gigatonnes of CO2.

Manmade emissions in 2018 alone topped 37 gigatonnes.

“The amount of CO2 pumped into the atmosphere by anthropogenic (manmade) activity in the last 10-12 years (is equvalent) to the catastrophic change during these events we’ve seen in Earth’s past,” Edmonds told AFP.

Celina Suarez, Associate Professor of Geology at the University of Arkansas, said modern manmade emissions were the “same magnitude” as past carbon shocks that precipitated mass extinction.

“We are on the same level of carbon catastrophe which is a bit sobering,” she told AFP.

‘Not a human timescale’

By comparison, the CO2 released annually by volcanoes hovers around 0.3 and 0.4 gigatonnes—roughly 100 times less than manmade emissions.

“Climate sceptics really jump on volcanoes as a possible contender for top CO2 emissions but it’s simply not the case,” said Edmonds.

“It’s also the timescale.”

Whereas Earth’s atmosphere has frequently contained higher concentrations of CO2 than the present day, outside of catastrophic eruptions it has taken hundreds of thousands of years for such levels to accumulate.

In contrast, manmade carbon emissions have seen CO2 levels rise two thirds in a span of a few centuries.

“Climate deniers always say that Earth always rebalances itself,” said Suarez.

“Well, yes it has. It will rebalance itself, but not on a timescale that is of signficance to humans.”

Scary statistic: 90.5 percent of plastic is not recycled

The world’s burgeoning plastic waste crisis has won the attention of Britain’s Royal Statistical Society, which chose 90.5 percent—the proportion of plastic waste that has never been recycled—as its international statistic of the year.

The society, which chooses a winner from nominations made by the public, picked the statistic generated in a U.N. report based on the work of U.S. academics Roland Geyer, Jenna R Jambeck and Kara Lavender Law.

Public awareness of the problem has been growing, particularly after filmmaker David Attenborough’s documentary “Blue Planet II” showed sea turtles shrouded in plastic, among other horrors.

Geyer says he was honored by the accolade and hopes “it will help draw attention to the problem of plastic pollution that impacts nearly every community and ecosystem globally.”

Rainforest destruction from gold mining hits all-time high in Peru

November 8, 2018

Small-scale gold mining has destroyed more than 170,000 acres of primary rainforest in the Peruvian Amazon in the past five years, according to a new analysis by scientists at Wake Forest University’s Center for Amazonian Scientific Innovation (CINCIA).

That’s an area larger than San Francisco and 30 percent more than previously reported.

“The scale of the deforestation is really shocking,” said Luis Fernandez, executive director of CINCIA and research associate professor in the department of biology.

The scientists at CINCIA, based in the Madre de Dios region of Peru, have developed a new data fusion method to identify areas destroyed by this small- or artisanal-scale mining. Combining existing CLASlite forest monitoring technology and Global Forest Change data sets on forest loss, this new deforestation detection tool is 20-25 percent more accurate than those used previously.

Both CLASlite and the Global Forest map use different kinds of information from light waves to show changes in the landscape. “Combining the two methods gives us really good information about the specific kind of deforestation we’re looking for,” said Miles Silman, associate director of science for CINCIA and director of Wake Forest’s Center for Energy, Environment, and Sustainability (CEES). Silman has researched biodiversity and ecology in the Western Amazon and Andes for more than 25 years.
