Science and Socialism

The issues posed by the worldwide March for Science

20 April 2017

Hundreds of thousands of scientists and other professionals, together with students and working people who support them, will take part this Saturday in the worldwide March for Science. The demonstration has evoked a significant response, in large measure because it is seen as a way to protest the Trump administration’s attacks on scientific knowledge and investigation.

The Socialist Equality Party welcomes this demonstration. We call for the mobilization of working people throughout the world against the destruction of the environment by giant chemical and energy corporations; attacks on public education that threaten access to all aspects of human culture for an entire generation of young people; the subordination of science to the profit requirements of the ruling class and the military; and all censorship and restrictions on research and teaching.

The call for the March for Science refers to these issues, but it has definite limitations, summed up in its declaration that the attacks on science “are not a partisan issue.” This question must be understood correctly. The defense of science is only “nonpartisan” in the sense that both Democrats and Republicans are responsible for the attack on public education, the deteriorating environment, the growth of militarism and the effort to censor and suppress scientific research.

The defense of science is, however, profoundly political, as it has been throughout history, as far back as Galileo Galilei’s trial by the Roman Catholic Inquisition. Every reactionary government and class persecutes scientists and seeks to suppress and subordinate science to its own ends. The progress of science and reason has always depended upon the progress of society and social relations—and this is a political question.

The challenge today is to recognize the source of the attack on science, which did not suddenly arise from the limited brain of Donald Trump. He is only the crudest and most backward representative of a social system in which all human activity, including science, is subordinated to private profit. While science and technology have immensely developed the power of social production, this production remains trapped within the increasingly irrational forms of private capitalist ownership.

The defense of science is therefore inseparable from the revolutionary struggle of the main progressive force in modern society, the working class, against the corporate ruling elite.

Science and technology have made it possible to abolish hunger, cure disease, banish ignorance and secure a decent standard of living for every person on this planet. But under the profit system, vast wealth is monopolized by a tiny handful of the super-rich. Just eight mega-billionaires possess greater wealth than the poorest half of humanity, while hundreds of millions go hungry; millions die of preventable diseases; and schools, roads, water systems and other public infrastructure are crumbling.

Modern technology, from revolutionary developments in transportation to the creation of the Internet, has shattered the barriers to human interaction and made possible the integration of all humanity. Science itself is the most international of human enterprises, developing through global collaboration.

However, because of the division of the world into rival nation-states, technology is made the instrument of repression and persecution: the hounding of refugees and immigrants throughout the world; the building of walls against immigrants on the US-Mexico border; China’s “great firewall,” separating one billion people from the rest of the world; and the development of the NSA’s vast apparatus of global spying directed against the population of the entire world.

Most ominously, in the hands of the rival nation-states, with US imperialism taking the lead, science and technology have been perverted into means of mass destruction. The April 22 demonstration takes place under conditions of a growing threat of world war, with the Trump administration, backed by the US media and Democratic Party, firing missiles at Syria, dropping the largest bomb since Hiroshima and Nagasaki on Afghanistan, and threatening a preemptive military strike against North Korea.

The danger of a direct military conflict involving nuclear-armed powers is very real. More than anyone else, scientists know that this would mean the extinction of civilization, if not life on planet Earth.

What is the way forward? Those who wish to defend and advance the work of science must confront a contradiction in their own ways of thinking. They are accustomed to applying scientific methods to the processes of nature, but not to the workings of society, still less to politics.

In part, this derives from the greater complexity of social life, where the number of variables—including human beings—makes scientific analysis more complicated. More importantly, it reflects the ideological domination of the corporate ruling elite, which opposes efforts to apply rational standards to the operations of a social system that affords them unparalleled wealth and privilege. Within academia, the attack on objective truth and reason spearheaded by postmodernism and other forms of irrationalism is directed at all forms of scientific knowledge, above all at the science of society and history.

Scientists must find their way back to insights of their greatest predecessors like Albert Einstein, who were drawn to socialism as the application of reason to the development of modern society—and as the only means of ending war and dictatorship. This means taking up a study of Marxism, which bases its revolutionary politics on an analysis of objective reality and class interests.

The working class is the revolutionary force that has the capability to put an end to capitalism and establish a socialist society based on equality, democracy and social ownership of the wealth created by collective labor. In the Russian Revolution, whose centenary we mark this year, this scientific understanding was vindicated in practice, with the working class coming to power under the leadership of a Marxist party.

The working class cannot advance without the aid of science. But science itself requires the advance of the working class, which will provide science with the necessary mass base in society. In the final analysis, the progress of science—and the progress of humanity as a whole—depends on the resurgence of a new revolutionary movement of the working class. The socialist movement unites under its banner both the pursuit of scientific truth in all its forms and the struggle for human equality.

Trump’s assault on science ultimately rests on his hostility toward truth, an idea with a complicated history

The Trump administration’s war on the environment, which was accelerated this week with the president’s executive order to dismantle various environmental protections, is a product of the administration’s larger war on science, which is in turn a manifestation of President Trump’s unrelenting assault on the truth.

While “truth” and “objectivity” are endlessly debated in the field of journalism, no branch of human knowledge is more established on empirical evidence than the natural sciences, which seek to understand and describe the world through experimentation. One’s attitude toward the natural sciences and the scientists who dedicate their lives to research, therefore, can reveal a lot about one’s attitude toward truth in general.

By now it should be obvious that Trump, who once claimed that climate change was a hoax created by the Chinese, has very little respect for the natural sciences. This week we learned just how little the president cares about the expertise of scientists, with a New York Times article reporting that the staff of the White House Office of Science and Technology Policy has been completely decimated since Trump entered office. This elimination of STEM experts from advisory positions is consistent with President Trump’s other anti-science policies, including his call for cuts to the EPA, NASA and NOAA, as well as his sweeping deregulatory agenda on the environment.

Trump’s hostility towards science and scientific facts like climate change is characteristic of his “post-truth” outlook, and his administration’s anti-science agenda is just one part of his larger crusade against objective truth.

This crusade has involved the president relentlessly attacking the media as “fake news” while simultaneously peddling false stories and citing genuinely fake news publications himself. He has been so successful at this that Time magazine came right out and asked it on its latest cover: “Is Truth Dead?” With same font and format as the magazine’s famous “Is God Dead?” cover from 1966, it includes a remarkable interview with the president, who manages to make about a dozen false, unverifiable or misleading statements in one sitting.

Whether deliberate or not, the cover headline alludes to the German philosopher Friedrich Nietzsche, who is best known for proclaiming the death of God, but also for rejecting the idea of objective truth (“there are no facts, only interpretations”). For the philosophically inclined, then, our “post-truth” era can be traced back to Nietzsche, as the lecturer in philosophy Alexis Papazoglou did last December in an article for the Conversation on the philosopher’s theory of “perspectivism.” According to Papazoglou, Nietzsche posits that, “once we realise that the idea of an absolute, objective truth is a philosophical hoax, the only alternative is a position called ‘perspectivism’ – the idea there is no one objective way the world is, only perspectives on what the world is like.” Papazoglou continues:

According to perspectivism, we agree on [basic facts, like that Paris is the capital of France] not because these propositions are ‘objectively true,’ but by virtue of sharing the same perspective. … but when it comes to issues such as morality, religion and politics, agreement is much harder to achieve.

While it is doubtful whether Trump has ever heard of Nietzsche — and even more doubtful whether he could get through one paragraph of the philosopher’s cryptic prose — the president is quite the perspectivist in his own crass and superficial way (much as he is a crude caricature of Nietzsche’s idealized Übermensch). In his Time interview, the president claimed to be a very “instinctual person,” which one can take to mean that he seldom questions his own perspective or feels the need to verify a claim that he feels in his gut before stating it as fact (even when, as president of the United States, he has access to top secret information).

If there are really no facts and only interpretations, and if millions of Americans are ready to unthinkingly embrace your perspective, then why bother adhering to a rigid line that separates fact from fiction? If you interpret a period of cold weather as evidence that climate change isn’t happening, and if millions of other people agree with your point of view, then climate change is a hoax. If your subjective experience perceives record attendance at the inauguration, then there was record attendance — aerial photographs that prove otherwise are simply illustrating another perspective.

Nietzsche was a major influence on the French postmodern philosophers of the late 20th century, who adopted a similar perspectivist view of objective truth and rejected the “grand narratives” of the Enlightenment and modernism. (Not surprisingly, these thinkers do not have a good reputation in the scientific community; see the notorious Sokal affair). As a philosophical movement, postmodernism is mostly known for the contention that all human knowledge is a product of social constructions and competing narratives — including scientific knowledge, which is no more or less true than, say, Jacques Derrida’s theory of deconstruction.

While prominent postmodernist thinkers were almost all on the left, and used their theories to critique dominant ideologies and powerful interests, their work did not go unnoticed by those on the right. In an interview with the New Yorker last October, Mike Cernovich, one of the leading online personalities of the alt-right, discussed postmodernism and the importance of narratives: “Let’s say, for the sake of argument, that Walter Cronkite lied about everything. Before Twitter, how would you have known? Look, I read postmodernist theory in college. If everything is a narrative, then we need alternatives to the dominant narrative.” Like many other alt-right figures Cernovich made his name on Twitter, which has become an invaluable tool for promoting different “narratives,” whether it be climate change denialism or voter fraud conspiracy theories or fables of the deep state.

So the right has managed to successfully adopt a postmodern style of politics, where alternative facts counter objective truth and alternative narratives create a new, paranoid picture of the world. It is far from certain, however, that this kind of postmodern (or post-truth) politics is sustainable in the long run — especially now that Trump and the Republican Party are in control of the government.

Two and a half months into his term, Trump’s presidency has been nothing short of a disaster, and this is largely because the president has shunned experts who operate in the real world (like, er, scientists), while surrounding himself with know-nothing sycophants who dare not contradict his fact-free worldview. If Trump continues to govern as a post-truth president disconnected from reality, all signs point to an eventual collapse. Then again, it’s all a matter of perspective.

It’s not an attack on the arts, it’s an attack on communities

Art and architecture critic March 16 at 3:03 PM
Things could get worse, much worse. The president’s proposed budget eliminates much of the government’s long-standing commitment to the arts, to science, to education, to culture, to public broadcasting and community development. It calls not only for the elimination of the National Endowment for the Arts, the National Endowment for the Humanities, the Corporation for Public Broadcasting and the Institute of Museum and Library Services, but also proposes the elimination of groups such as the Woodrow Wilson Center, a highly respected think tank that studies national and international affairs and just happens to be hosting a program Thursday called “The Muse of Urban Delirium: How the Performing Arts Paradoxically Transform Conflict-Ridden Cities Into Centers of Cultural Innovation.” It’s almost as if someone tried to fit as many dirty words — dirty in the current administration’s way of thinking — into one evening: Arts, Cities, Culture, Paradox, Innovation.

These cuts aren’t about cost savings — they’re far too small to make even a ding in the federal budget. They are carefully calculated attacks on communities, especially those that promote independent thinking and expression, or didn’t line up behind the Trump movement as it swept to power through the electoral college in November. But the president’s proposed budget also includes attacks on communities that did indeed support Trump but that are too powerless to resist. Among the independent agencies set for elimination: the Appalachian Regional Commission, which supports things such as job training, economic diversification (including the arts), tourism initiatives and Internet access in states like West Virginia, Alabama and Kentucky.

The strategy, perfectly calculated for a new era of rancor and resentment amplified by social media, is to focus people not on what will be lost, but who will lose. Why attack communities that support you? Because losing isn’t just a question of what side, what arguments, what ideology prevails in the political debate. Rather, losing is a stigma, a scarlet letter to hang on the necks of people who are losers. Losers are essential to the project of building a new political coalition, a coalition that celebrates winning. Winners are strong; losers are sad. If your aversion to being branded a loser is strong enough, you may even embrace policies that cause you harm.

President Trump’s proposed budget calls for the elimination of the National Endowment for the Arts, the National Endowment for the Humanities, the Institute of Museum and Library Services, and the Corporation for Public Broadcasting. Small and rural programs would be hit hardest. (Erin Patrick O’Connor/The Washington Post)

Read through The Washington Post’s coverage of the budget proposal, and you hear what begins to sound like a broken record: These cuts will primarily affect marginalized or minority communities, people on the losing end of the American Dream. From an article about the Interior Department: “Historic-sites funding is important,” according to one expert, “because it supports tribal preservation officers and provides grants to underrepresented communities.” Or from the Labor Department: “The Trump administration proposed $2.5 billion in cuts for the Labor Department in a plan that would significantly reduce funding for job training programs for seniors and disadvantaged youth.”

Just in time for today’s announcement is an op-ed by Washington Post columnist George Will, who also calls for the elimination of the NEA. Will’s article would be a risible period piece — he is still seething over culture-war debates from more than a quarter century ago — if his hostility to the arts were not politically empowered by the democratic peculiarities of the last election, which brought into office a deeply unpopular president allied (for now) to a Congress pursuing deeply unpopular policies because many of its members are protected by gerrymandering.

Will rehashes the usual arguments: He reminds readers of a handful of grants that were deemed offensive by some in the early 1990s; he asserts that people will pay for the arts if they want the arts, and that state and local arts agencies will step up if the federal government (which helps fund these agencies) forsakes them; and argues that the arts are no different, no more a social good, have no more utility or spiritual value than “macaroni and cheese.” He not only fails to understand the nature of the arts, he also fails to understand the uniquely American three-legged stool system of federal stimulus allied to state and local support and bolstered by private donations that has enriched the arts and the country for more than half a century.

“The myriad entities with financial interests in preserving the NEA cloyingly call themselves the ‘arts community,’ a clever branding that other grasping factions should emulate,” he writes, cloyingly. “The ‘arts community’ has its pitter-patter down pat. The rhetorical cotton candy — sugary, jargon-clotted arts gush — asserts that the arts nurture ‘civically valuable dispositions’ and a sense of ‘community and connectedness.’ And, of course, ‘diversity’ and ‘self-esteem.’ ”

The arts have a powerful economic effect on our society and employ vast numbers of people, but the arts community is hardly an assemblage of cynical, self-interested, deep-pocketed financial interests (for that, look to the president’s Cabinet). The “pitter-patter” of this rapacious arts juggernaut is indeed well practiced by now, but only because attacks on the arts are now a seasonal performance from a determined minority political faction. The arts do indeed foster a sense of “community and connectedness” . . . in places like Nebraska, Alaska, Missouri, Nevada, Georgia, Tennessee and Alabama. And the other 43 states of the Union. And not only do they nurture diversity, they also express and preserve the variegated richness of culture celebrated in that musty old Latin phrase “E pluribus unum” (it’s on the money, if you want to check).

But the most jejune moment of Will’s extraordinary performance is this: “What, however, is art? We subsidize soybean production, but at least we can say what soybeans are.” For a few centuries now, it has been the nature of art to wonder what art is. That’s how the arts think, how they operate, how they define the parameters of aesthetic experience. And for the entire history of the species, art has been fundamentally different, less tangible, less utilitarian in its function, than soybeans. These things are obvious, if you’ve ever spent time with the arts community, which in fact exists and adds immeasurably to the stability, cohesion, intelligence, beauty and resilience of the nation.

Record-low sea ice as Arctic temperatures soar

By Daniel de Vries
22 November 2016

Never since satellite monitoring began in the late 1970s has such little ice covered the polar seas this time of year. In both the Arctic and the Antarctic, the extent of sea ice is tracking at the lowest levels on record.

The onset of polar night in the Arctic, in which the sun never rises above the horizon, typically triggers rapid ice growth as consistently bitter cold temperatures chill the warmer seas. However over the past two months, temperatures in the high Arctic have remained unusually warm. Temperatures last week rose to a startling 20 degrees Celsius (38 degrees Fahrenheit) above the historical average.

This extraordinary warmth is in part attributable to shrinking ice cover and may well drive further losses. And it is not just high air temperatures. Mark Serreze of the National Snow and Ice Data Center explained to the Washington Post, “There are some areas in the Arctic Ocean that are as much as 25 degrees Fahrenheit (14 degrees Celsius) above average now,” he said. “It’s pretty crazy.”

While it is too early to say whether this season’s winter ice maximum will set a new low, the long-term trends are unmistakable. The decline of ice, particularly in the Arctic, is recognized by climate scientists as an alarming indicator of a warming planet. The amount of ocean area covered by at least 15 percent ice reached a minimum in 2012, with the subsequent years all well below the long-term average.

It is not only the extent of the ice that concerns scientists, but its shrinking thickness and age. According to NASA, a comparison between September 2014 and September 1984 shows a decline of older ice, four years old or more, by a staggering 94 percent. Virtually all of the older, thicker ice has melted away or thinned, leaving the region more vulnerable to additional melting during relatively warm weather.

Sea ice extent this year compared to long term average

This vulnerability is not merely a theoretical possibility. At the end of 2015, for example, a storm and warm spell triggered the loss of ice over an area the size of Florida at a time when the ice pack would normally be growing, according to a recent analysis by NASA’s Goddard Institute. The “extremely warm” temperatures were 10 degrees Celsius above normal, half the magnitude of the current warm spell.

The current extraordinarily high temperature abnormalities in the Arctic are matched by equally cold deviations spanning almost the entirety of the vast region of Siberia. This month, nearly 140 low temperature records were set in Russia, from the Finland border to the Sea of Japan. Schools in central Russia shuttered as temperatures plunged to negative 36 Celsius (negative 33 Fahrenheit).

2016 daily mean Arctic Temperater (red) compared to long term mean (green)

The record heat in the Arctic and cold over the continents are linked. Jennifer Francis, a climatologist at Rutgers University, told the Post, “The Arctic warmth is the result of a combination of record-low sea-ice extent for this time of year, probably very thin ice, and plenty of warm/moist air from lower latitudes being driven northward by a very wavy jet stream.”

An increasing amount of research has tied changes in atmospheric circulation patterns to the loss of Arctic sea ice. The wintertime Arctic polar vortex, a circulating zone of low pressure extending several miles up in the atmosphere, has weakened over the past few decades, together with retreating sea ice. This weakened and perhaps shifting vortex allows colder weather, normally confined to the polar region, to escape farther south. The current weather patterns appear to be a prime example of this phenomenon.

Vast changes are afoot not only in the northern latitudes but in the Antarctic as well. In recent years, up through 2014, the region had seen growth in winter sea ice extending into the Southern Ocean. While these gains were far outweighed by the losses in the Arctic, this year has brought a stark reversal. Now, for the first time, sea ice extents near both poles are on course for record lows.

As earth warms, diseases within permafrost become a bigger worry

Scientists are witnessing the theoretical turning into reality: infectious microbes emerging from a deep freeze

This article was originally published by Scientific American.

Scientific AmericanThis past summer anthrax killed a 12-year-old boy in a remote part of Siberia. At least 20 other people, also from the Yamal Peninsula, were diagnosed with the potentially deadly disease after approximately 100 suspected cases were hospitalized. Additionally, more than 2,300 reindeer in the area died from the infection. The likely cause? Thawing permafrost. According to Russian officials, thawed permafrost — a permanently frozen layer of soil — released previously immobile spores of Bacillus anthracis into nearby water and soil and then into the food supply. The outbreak was the region’s first in 75 years.

Researchers have predicted for years that one of the effects of global warming could be that whatever is frozen in permafrost — such as ancient bacteria — might be released as temperatures climb. This could include infectious agents humans might not be prepared for, or have immunity to, the scientists said. Now they are witnessing the theoretical turning into reality: infectious microorganisms emerging from a deep freeze.

Although anthrax occurs naturally in all soil and outbreaks unrelated to permafrost can occur, extensive permafrost thaw could increase the number of people exposed to anthrax bacteria. In a 2011 paper published in Global Health Action, co-authors Boris A. Revich and Marina A. Podolnaya wrote of their predictions: “As a consequence of permafrost melting, the vectors of deadly infections of the 18th and 19th centuries may come back, especially near the cemeteries where the victims of these infections were buried.”

And permafrost is indeed thawing — at higher latitudes and to greater depths than ever before. In various parts of Siberia the active layer above permafrost can thaw to a depth of 50 centimeters every summer. This summer, however, there was a heat wave in the region, and temperatures hovered around 35 degrees Celsius — 25 degrees warmer than usual. The difference possibly expanded or deepened the thaw and mobilized microorganisms usually stuck in rigid earth. Although scientists have yet to calculate the final depth, they postulate that it is a number that has not been seen in almost a century. Permafrost thaw overall could become widespread with temperatures only slightly higher than those at present, according to a 2013 study in Science. Heat waves in higher latitudes are becoming more frequent as well.

What thawing permafrost could unleash depends on the heartiness of the infectious agent involved. A lot of microorganisms cannot survive in extreme cold, but some can withstand it for many years. “B. anthracis are special because they are sporulating bacteria,” said Jean-Michel Claverie, head of the Mediterranean Institute of Microbiology and a professor at Aix-Marseille University in France. “Spores are extremely resistant and, like seeds, can survive for longer than a century.”

Viruses could also survive for lengthy periods. In 2014 and 2015, Claverie and his colleague Chantal Abergel published their findings on two still infectious viruses from a chunk of 30,000-year-old Siberian permafrost. Although Pithovirus sibericum and Mollivirus sibericumcan infect only amoebas, the discovery is an indication that viruses that infect humans — such as smallpox and the Spanish flu — could potentially be preserved in permafrost.

Human viruses from even further back could also make a showing. For instance, the microorganisms living on and within the early humans who populated the Arctic could still be frozen in the soil. “There are hints that Neandertals and Denisovans could have settled in northern Siberia [and] were plagued by various viral diseases, some of which we know, like smallpox, and some others that might have disappeared,” Claverie said. “The fact that there might be an infection continuity between us and ancient hominins is fascinating — and might be worrying.”

Janet Jansson, who studies permafrost at the Pacific Northwest National Laboratory in Washington State, is not worried about ancient viruses. Several attempts to discover these infectious agents in corpses have come up empty, she notes. She does advocate, however, for further research to identify the wide range of permafrost-dwelling organisms, some of which could pose health risks. To accomplish that goal, she and others are using modern molecular tools — such as DNA sequencing and protein analysis — to categorize the properties of unknown microorganisms, sometimes referred to as microbial dark matter.

The likelihood and frequency of outbreaks similar to the one in Siberia will depend on the speed and trajectory of climate change. For instance, it is possible that another heat wave will expose the carcasses of animals infected by anthrax, Revich said. “The situation on the Yamal Peninsula has shown that the risk of the spread of anthrax is already real,” he added.

In effect, infectious agents buried in the permafrost are unknowable and unpredictable in their timing and ferocity. Thus, researchers say thawing permafrost is not our biggest worry when it comes to infectious diseases and global warming. The more immediate, and certain, threat to humans is the widening geographical ranges of modern infectious diseases (and their carriers, such as mosquitoes) as the earth warms. “We now have dengue in southern parts of Texas,” said George C. Stewart, McKee Professor of Microbial Pathogenesis and chair of the department of veterinary pathobiology at the University of Missouri. “Malaria is seen at higher elevations and latitudes as temperatures climb. And the cholera agent, Vibrio cholerae, replicates better at higher temperatures.”

Unlike the zombie microbes lurking in the permafrost, modern spreading diseases are more of a known quantity, and there are proved ways to curb them: mapping trends, eliminating mosquito-breeding sites and spraying insecticides. Of course, dramatically lowering fossil-fuel emissions to combat climate change could tackle both threats — the resurgence of ancient and deadly pathogens and the widening ranges of infectious diseases — in one shot.

Study finds that one in six species are in danger of extinction due to climate change

extinctionrisk_rpearce

By Philip Guelpa
25 June 2015

An article published this past April in the journal Science predicts that up to one in six animal and plant species on earth are in danger of extinction due to climate change. The study, authored by Mark Urban, an ecologist at the University of Connecticut, concludes that as the global climate warms, the rate of extinction, already high, will accelerate.

Previous studies, dating back more than a decade, have already shown that global warming, which has increased earth’s temperature by an average of 1.5 degrees Fahrenheit (0.8 degrees Celsius) since the Industrial Revolution, has had notable effects on species distributions. It pushes species to higher latitudes and higher altitudes, following the cooler temperatures to which they are adapted. Scientific projections indicate that the rate of warming is accelerating, and global temperatures may rise at least 8 degrees F. (4.5 degrees C.), if present trends continue.

Such drastic changes in climate would far outpace the rate at which species could adapt by evolutionary mechanisms. Many would, quite literally, run out of room, reaching the tops of mountains or the far reaches of the northern and southern hemispheres, where ecological crowding and differing environmental settings would drive many to extinction.

Urban’s research was based on a reanalysis (known as a meta-analysis) of data from 131 previous studies of species extinction from around the world. He concludes that the rate of increase in extinctions would be greater if temperatures reach the higher end of predicted ranges. With a rise of 3.6 degrees F. (2.0 C.), 5.2 percent of species would become extinct, but with an increase of 7.7 degrees F. (4.3 C.) the extinction rate would rise to 16 percent. Larger changes in temperature can be expected to have even more severe consequences.

It must be remembered that these estimates represent global averages. Regional variations are likely to produce a range of results. For example, studies have revealed that the polar regions are warming at notably more rapid rates than are the lower latitudes. As temperatures in these areas increase, cold-adapted species will simply have no place to go.

Another complicating factor is that there are likely to be synergistic effects. Complex, dialectical interrelationships exist between species in a given ecological setting. In- or out-migration, differing migration rates, or local extermination of key species would quite probably disrupt delicate balances of interdependence, causing a downward cascade of consequences for other species, likely making their situations more fragile and prone to extinction.

Less mobile species and those limited to restricted geographic ranges will be especially vulnerable. According to Urban, the highest rates of extinction are likely to occur in South America (23 percent), and Australia and New Zealand (14 percent each).

The danger is not merely that of the loss of individual species, or even large numbers of species, but of the collapse of entire ecosystems, with incalculable, but no doubt very severe consequences for humans.

Urban’s study clearly demonstrates the need for a substantial increase in research on the effects of climate change on species and ecosystems. However, no amount of such research will ameliorate the causes of these extinctions. Furthermore, Urban points out that even species that do not go extinct will suffer major, mostly detrimental consequences due to climate change.

Massive extinctions due to naturally induced climate changes have occurred repeatedly in the past (see: The Sixth Extinction by Elizabeth Kolbert). There is a widespread scientific consensus that human activity, if present trends continue, is likely to cause disruptions on a similar scale.

However, despite clear warnings of dire consequences, including massive disruptions to human society, business interests and the political structures that represent them have prevented any meaningful efforts to address the activities that are driving the process (see: Climate report warns of “severe, pervasive and irreversible impacts”).

A massive, coordinated scientific and technological effort is needed to avert an otherwise inevitable environmental disaster. That will only be possible, however, if control of the economy is taken away from super-rich corporate interests, whose overriding motivation is short-term profit regardless of the consequences. Only a rationally planned program based on the interests of the working class, including the need for a livable planet, can address this crisis.

Why America’s obsession with STEM education is dangerous

 

STEM_Logo

According to an op-ed by Fareed Zakaria in the Washington Post, if Americans are united in any conviction these days, it is that we urgently need to shift the country’s education toward the teaching of specific, technical skills, expand STEM courses (science, technology, engineering and math) and deemphasize the humanities. “It is the only way, we are told, to ensure that Americans survive in an age defined by technology and shaped by global competition. The stakes could not be higher.” But according to Zakaria the dismissal of broad-based learning, however, comes from a fundamental misreading of the facts — and puts America on a dangerously narrow path for the future.

As Steve Jobs once explained “it’s in Apple’s DNA that technology alone is not enough — that it’s technology married with liberal arts, married with the humanities, that yields us the result that makes our hearts sing.” Zakaria says that no matter how strong your math and science skills are, you still need to know how to learn, think and even write and cites Jeff Bezos’ insistence that writing a memo that makes sense is an even more important skill to master. “Full sentences are harder to write,” says Bezos. “They have verbs. The paragraphs have topic sentences. There is no way to write a six-page, narratively structured memo and not have clear thinking.” “This doesn’t in any way detract from the need for training in technology,” concludes Zakaria, “but it does suggest that as we work with computers (which is really the future of all work), the most valuable skills will be the ones that are uniquely human, that computers cannot quite figure out — yet. And for those jobs, and that life, you could not do better than to follow your passion, engage with a breadth of material in both science and the humanities, and perhaps above all, study the human condition.”
