(don’t) spend a penny

But the rise of bitcoin is also happening at a specific moment in history: Humanity is decades behind schedule on counteracting climate change, and every action in this era should be evaluated on its net impact on the climate. Increasingly, bitcoin is failing the test….

But what they might not have accounted for is how much of an energy suck the computer network behind bitcoin could one day become. Simply put, bitcoin is slowing the effort to achieve a rapid transition away from fossil fuels. What’s more, this is just the beginning. Given its rapidly growing climate footprint, bitcoin is a malignant development, and it’s getting worse…..

In just a few months from now, at bitcoin’s current growth rate, the electricity demanded by the cryptocurrency network will start to outstrip what’s available, requiring new energy-generating plants. And with the climate conscious racing to replace fossil fuel-base plants with renewable energy sources, new stress on the grid means more facilities using dirty technologies.

I know where I’m placing my bet!

Humans will be extinct in 100 years because the planet will be uninhabitable, according to Australian microbiologist Frank Fenner, one of the leaders of the effort to eradicate smallpox in the 1970s. He blames overcrowding, denuded resources and climate change.

“For years now, we have heard that we are at a tipping point. Al Gore warned us in An Inconvenient Truth that immediate action was required if we were to prevent global warming.”

“Only two conclusions can be drawn: Either these old warnings were alarmist, or we are already in far bigger trouble than the U.N. Claims.”

frenzied beetles upset apple cart

Climate change could be throwing common tree killers called mountain pine beetles into a reproductive frenzy.

A new study suggests that some beetles living in Colorado, which normally reproduce just once annually, now churn out an extra generation of new bugs each year.

The insects, says Jeffry Mitton, an evolutionary geneticist at the University of Colorado, Boulder, were swarming close to 2 months too early that year.

It seemed so implausible that when he told colleagues about the encounter, some didn’t believe him. “This would really upset the apple cart,” Milton remembers thinking.

back to the trees!

Climate justice is the understanding that we will not be able to stop climate change if we don’t change the neo-liberal, corporate-based economy which stops us from achieving sustainable societies. It is the understanding that corporate globalization must be stopped.

Indigenous Peoples, peasant communities, fisherfolk, and especially women in these communities, have been able to live harmoniously and sustainably with the Earth for millennia.

They are now not only the most affected by climate change, but also the most affected by its false solutions, such as agrofuels, mega-dams, genetic modification, tree plantations and carbon offset schemes.

Instead of market-based climate mitigation schemes, the sustainable practices of these peoples and communities should be seen as offering the real solutions to climate change.

All is lost!

From depression to substance abuse to suicide and post-traumatic stress disorder, growing bodies of research in the relatively new field of psychology of global warming suggest that climate change will take a pretty heavy toll on the human psyche as storms become more destructive and droughts more prolonged.

For your everyday environmentalist, the emotional stress suffered by a rapidly changing Earth can result in some pretty substantial anxieties.

Two years ago, Camille Parmesan, a professor at Plymouth University and the University of Texas at Austin, became so “professionally depressed” that she questioned abandoning her research in climate change entirely.

“I don’t know of a single scientist that’s not having an emotional reaction to what is being lost,” Parmesan is quoted saying in the National Wildlife Federation’s 2012 report.

we’re the problem

When kangaroo numbers rise beyond the land’s ability to sustain them, we cull them. When rabbits breed like, well rabbits, we poison them.

Given the terrible damage that billions of humans are inflicting on Earth, why are we not controlling our numbers, albeit in more humane ways?

A report published recently by Britain’s Optimum Trust said: “The most effective personal climate change strategy is limiting the number of children one has. The most effective national and global climate change strategy is limiting the size of the population”

It warned in its report that each Briton produced nearly 750 tonnes of carbon dioxide in a lifetime, equivalent to 620 return flights between London and New York.

Britain is expected to add another 10 million people by 2074. Multiply that by 75 Tonnes and you get, well, Buckleys chance of meeting well intentioned emission targets.

Just as Australia will have Buckley’s chance of meeting targets – and that’s assuming that those who masquerade as leaders set any – if its population keeps growing.

Thousands of fruit bats have flown down from the tropics to make Melbourne their home. A Deakin University researcher has found out why. Dr Parris figured climate change had to be the answer.

She had completed her PhD (on frogs) in Canberra with Dr Donna Hazell at the Australian National University’s centre for resource and environmental studies.

“The construction and continued expansion of our city, and the huge amount of water we use on our gardens, has made Melbourne warm enough and wet enough for the bats to live here year-round, while the watering also means trees flower and fruit for a longer period,” Dr Parris says.

evolutionary news

German birds are changing migration patterns. Canadian red squirrels are reproducing earlier in the year. Mosquitoes in Newfoundland remain active longer into August.

Traditionally, scientists have viewed such changes simply as behavior modifications in the face of a changing environment—in this case, global warming.

“Over the past 40 years, animal species have been extending their range toward the poles, and populations have been migrating, developing, or reproducing earlier,” said William Bradshaw, an evolutionary geneticist at the University of Oregon in Eugene.

But scientists say these shifts provide mounting evidence that for some animals, global warming is sparking genetic changes that are altering the ecosystems we live in.

waiting with bated breath

Now a new study, published Tuesday and coinciding with the UN climate talks in Paris, adds to the grim tableau: the risk that warming at the far end of the scale could rob our planet of oxygen.

We have identified another possible consequence of … global warming that can potentially be more dangerous than all others, say a pair of scientists from Britain’s University of Leicester.

Their study, based in the peer-reviewed journal the Bulletin of Mathematical Biology, is based on a computer model of phytoplankton, the microscopic sea plants which produce about two-thirds of the oxygen in the atmosphere.

“The message from this study is that there may be another disaster approaching us as a consequence of global warming, and it may be much worse than all other consequences identified previously,” co-author Sergei Petrovskii told AFP.

“There may be very little warning signs before the disaster actually happens… but once the critical threshold is passed (as estimated at 6 C), then the catastrophe will develop fast,” he explained by email.

we should have stayed in the trees!

The world’s first farmers and their slash-and-burn agriculture may have set off global warming.

A new analysis of ice-core climate data, archaeological evidence and ancient pollen samples is being used to suggest farming some 7,000 years ago helped put the brakes on a natural cooling process of the global climate, possibly contributing to the warmer climate seen today.

The study was the work of an international team led by William Ruddiman, a University of Virginia climate scientist, who first grabbed attention a dozen years ago with a controversial theory that humans altered the climate by burning massive areas of forests to clear the way for crops and livestock grazing.

“Early farming helped keep the planet warm,” Ruddiman said in a statement, regarding the study that appeared in a recent edition of the journal Reviews of Geophysics, published by the American Geophysical Union.

reptiles head for the hills

Global warming is forcing 30 species of reptiles and amphibians to move uphill as habitats shift upward, but they may soon run out of room to run.

Among 30 species of geckos, skinks, chameleons and frogs, an average shift uphill of 62 to 167 feet (19 to 51 meters) was observed over the decade.

When these results were compared with meteorological records and climate change simulations, the movement of animals could be linked to temperature increases of 0.18°F to 0.67°F (0.1°C to 0.37°C) over the same decade, which corresponds to an expected upslope movement of 59 to 243 feet (17 to 74 meters).

Crabgrass will get a strong assist from global warming in its campaign to take over your lawn.

That’s the unexpected finding of a study investigating a very different aspect of lawn biology: Neeta S. Bijoor, her graduate advisor Diane E. Pataki of the University of California, Irvine, and two colleagues set out to determine how warming affects lawns’ emission of nitrous oxide (N2O), a greenhouse gas 300 times more powerful than carbon dioxide.

In contrast to fescue and most other crop plants, crabgrass and many other weeds photosynthesize with greater efficiency the warmer it gets, so they have been predicted to proliferate as temperatures rise.

Climate change is coming for you in the night. That’s the conclusion of scientists who study how heat disturbs sleep—and how projected warming is expected to make bad sleep even worse.

Led by Nick Obradovich of Harvard University’s Belfer Center for Science & International Affairs, a team of researchers are the first to document the relationship between rising temperatures and poor sleep.

Their new study links that most individual of experiences—falling asleep—with a truly planetary phenomenon—global warming. Besides, the vagaries of climate modeling are secondary to the findings of the paper, Obradovich points out.

“Unusually warm temperatures produce reports of worsened sleep outcomes, even in a wealthy, mostly temperate country like the U.S.,” he said. “The warmer the future world becomes, the more we anticipate sleep to be affected.”

Over the past 25 years the tropics have expanded by as much as 300 miles (500 kilometers) north and south—evidence of climate change in action, a new study says.

This not only means that rain-drenched regions near the Equator are growing, experts say, but also that global warming may be pushing deserts poleward in places such as the U.S. Southwest, Mexico, Australia, South Africa, South America, and the Mediterranean.

“The rate of increase is pretty big,” said study lead author Dian Seidel of the National Oceanographic and Atmospheric Administration’s (NOAA) Air Resources Laboratory in Silver Spring, Maryland. “It’s several degrees of latitude over the course of 25 years.”

cutting South America loose

As noted by Michael Marshall in New Scientist, we could relink the Pacific and Atlantic Oceans: Destroying the Isthmus of Panama, the slender strip of land that joins North and South America, would reunite the Pacific and Atlantic oceans.

Underground nuclear explosions would do the trick. With the land gone, the ocean current that once flowed around the equator would restart and, allegedly, stabilise the climate.

Marshall also says we could flood the planet’s vast depressions, such as the Qattara depression in north-west Egypt and California’s Death Valley.

This could serve multiple purposes, including the creation of new bodies of water, the generation of hydroelectricity, and as a means to offset rising sea levels from global warming.

But on that last point, and as Marshall points out: “[It] is not worth doing for this reason alone: even if we flooded all of the world’s major depressions, it would barely make a difference.”

The rising demand for flat-screen televisions could have a greater impact on global warming than the world’s largest coal-fired power stations, a leading environmental scientist warned yesterday.

As a driver of global warming, nitrogen trifluoride is 17,000 times more potent than carbon dioxide, yet no one knows how much of it is being released into the atmosphere by the industry, said Michael Prather, director of the environment institute at the University of California, Irvine.

Writing in the journal Geophysical Research Letters, Prather and a colleague, Juno Hsu, state that this year’s production of the gas is equivalent to 67m tonnes of carbon dioxide, meaning it has “a potential greenhouse impact larger than that of the industrialised nations’ emissions of PFCs or SF6, or even that of the world’s largest coal-fired power plants”.

bad for your health

Climate change is already having an extraordinary impact on human health worldwide — affecting the spread of infectious diseases, exposing millions to air pollution and heat waves and dramatically reducing labor productivity, according to  a report released Monday.

The human symptoms of climate change are unequivocal and potentially irreversible, the report by the British medical journal The Lancet says, and the situation is so serious that significant gains by modern medicine and technology are being undercut.

The delayed response to climate change over the past 25 years has jeopardized human life and livelihoods, the report says.

“Preventing illnesses and injuries is more humane, more effective and more economical than treating people once they’ve become sick,” said Howard Frumkin of the University of Washington School of Public Health, one of the study authors.

“That’s plain common sense,” he added. “What this report makes clear is that fighting climate change is disease prevention.”

couldn’t be worse

The latest report on climate change by the economics professor Ross Garnaut is the most disheartening government report I’ve read.

Garnaut quotes an authoritative American study of the consequences if nothing is done to fight climate change and average temperatures rise by 5 or 6 degrees by the end of this century. Such a change would be “catastrophic”, posing “almost inconceivable challenges as human society struggled to adapt”.

“The collapse and chaos associated with extreme climate change futures would destabilise virtually every aspect of modern life,” the study concluded.

Among the destruction would be the extinction of more than half the world’s species. The Great Barrier Reef and other coral formations would almost certainly be killed and much Australian farmland rendered useless.

Worse, the Greenland ice sheet and parts of Antarctica would be highly likely to melt, greatly raising the sea level and inundating coastal areas in Australia and many other countries.

These changes would be irreversible.

calling the Avengers!

Federal wildlife officials plan to withdraw proposed protections for the snow-loving wolverine Tuesday, in a course reversal that highlights lingering uncertainties over what a warming climate means for some temperature-sensitive species.

Wolverines, or “mountain devils”, need deep snows to den. But while there is broad consensus that climate change will make the world warmer, drilling down to determine what that means for individual species remains difficult.

US Fish and Wildlife Service director Dan Ashe said predictions about climate change’s localized impacts remain “ambiguous”.

Rejecting the conclusions of the agency’s own scientists, Ashe said that made it impossible to determine whether less snow cover would put wolverines in danger of extinction in coming decades.

“Climate change is a reality,” Ashe said. “What we don’t know with reliability is what does climate change mean for denning habitat that wolverines prefer.”

He added, “It’s possible wolverines are adapting and continuing to adapt.””

We meant well.

Quereda et al. (2016) begin their work by stating that although “it may be accepted that urban heating is of local importance, there is no evidence that it alters the global temperature trend,” citing the IPCC (2001).

However, they backtrack significantly in this regard throughout their analysis of the subject by stating that “on comparing the temperature of urban areas and rural areas, various researchers have concluded that the urban effect could account for between 40% and 80% of the observed thermal trend in the last few decades,” citing the studies of Ren et al. (2007), Yan et al. (2010), and McKitrick and Michaels (2007), who concluded that half of the warming trend observed between 1980 and 2002 could have arisen from changes in land use.

In studying the subject in even more detail over the 1950-2013 period, it was further found that this phenomenon could “account for between 70 and 80% of the recorded warming trend in Western Mediterranean cities.”

And in light of this discovery, Quereda et al. pose the important question: “are urban areas contributing to the observed warming trend on which climate change is based?” to which they respond by stating that “the answer to be drawn from our analysis is fully affirmative.”

And so they conclude by stating that “in these Western Mediterranean cities, the Urban Heat Island could account for up to 80% of the recorded warming.”

What is the Earth’s optimum population? In view of global warming, many would argue that it’s lot less than it is currently.

Two weeks ago, British-based green think tank the Optimum Population Trust called for Britons to have fewer children. This, says an OPT report, is the best way for the planet to combat climate change.

If couples had two children instead of three, says the OPT, they could cut their family’s lifetime carbon dioxide output by the equivalent of 620 return flights a year between London and New York.

“The effect on the planet of having one child less is an order of magnitude greater than all these other things we might do, such as switching off light bulbs,” says John Guillebaud, co-chairman of the OPT and emeritus professor of family planning at University College, London.

“The greatest thing anyone in Britain could do to help the future of the planet would be to have one less child.”
