Smithsonian Magazine | Science & Nature | The Coldest Place in the Universe - 2 views

  • Where's the coldest spot in the universe? Not on the moon, where the temperature plunges to a mere minus 378 Fahrenheit. Not even in deepest outer space, which has an estimated background temperature of about minus 455°F. As far as scientists can tell, the lowest temperatures ever attained were recently observed right here on earth.
    Even on the moon, superconductors would need to be cooled.

Climate Change Messaging: Avoid the Truth » CounterPunch: Tells the Facts, Na... - 1 views

  • Ted Nordhaus and Michael Shellenberger published the op-ed “Global Warming Scare Tactics” in the New York Times on April 8. Participants in recent debates over climate change may recognize their names. They’re the guys who run the Breakthrough Institute, a pseudo-contrarian “environmental research organization.”
  • While occasionally on point in its charges against the big organizations, the essay (based on interviews with mostly white male leaders of large national groups) had nothing to say about the environmental justice movement, or other grassroots groups led by women and people of color. It neglected as well the environmental movements of the Global South, today the heart of the climate justice movement.
  • Is fear of disruption of what Habermas calls the life-world the sole inducer of civic action? Of course not: social movements also cohere around other shared, negotiated understandings, identities, diagnoses of problems, and assessments of opportunities. Might fear paralyze rather than mobilize? Yes: in cases when the perceived threat appears impervious to resistance, and when commitment to the cause flags over time. Fear-based campaigns require a tangible evil: a draft card, a nuclear plant cooling tower, a polluting facility’s smoke plume, an Operation Rescue picket line.

  • Of the massive, coordinated, ongoing effort by Exxon-Mobil, the Koch brothers, and the Heartland Institute (et al.) to do to climate science what the Tobacco Institute did to cigarette science, Nordhaus and Shellenberger have only this to say, “Some conservatives and fossil-fuel interests questioned the link between carbon emissions and global warming.”

    There’s no mention of how under- and mis-educated TV weathermen have been central progenitors of climate change skepticism. There’s no acknowledgement of how Big Coal, Oil and Gas have bought off local and national legislators, stalled attempts to put forward even wimpy programs (like cap and trade), or underwritten NPR’s gushing embrace of fracking.

This Changes Everything: Capitalism vs the Climate review - Naomi Klein's powerful and ... - 0 views

  • Much of this book is concerned with showing that powerful and well-financed rightwing thinktanks and lobby groups lie behind the denial of climate change in recent years.
  • Klein interprets the marginalisation of climate change in the political process as the result of the machinations of corporate elites. These elites “understand the real significance of climate change better than most of the ‘warmists’ in the political centre, the ones who are still insisting that the response can be gradual and painless and that we don’t need to go to war with anybody… The deniers get plenty of the details wrong… But when it comes to the scope and depth of change required to avert catastrophe, they are right on the money.”
  • Klein is a brave and passionate writer who always deserves to be heard, and this is a powerful and urgent book that anyone who cares about climate change will want to read. Yet it is hard to resist the conclusion that she shrinks from facing the true scale of the problem. When I read The Shock Doctrine (Guardian review headline: “The end of the world as we know it”), I was unconvinced that corporate and political elites understood what they were doing in promoting the wildly leveraged capitalism of that time, which was already beginning to implode. The idea that corporate elites are in charge of the world is even less convincing today. The neoliberal order has recovered, and in some countries even achieved a spurious kind of stability, but only at the cost of worsening global conflicts.

  • Another problem with pinning all the blame for climate crisis on corporate elites is that humanly caused environmental destruction long predates the rise of capitalism.
  • Though she identifies the prevailing type of capitalism as the culprit in the climate crisis, Klein doesn’t outline anything like an alternative economic system, preferring instead to focus on particular local struggles against environmental damage and exploitation. In many ways this makes sense, but in a global environment of intensifying scarcities, giving priority to local needs is unlikely to be a recipe for harmony. Whether in the Congo in the 1960s or Iraq at the present time, internecine conflicts – exploited and aggravated by the geopolitical stratagems of great powers – have led to a condition of endemic war.
  • Throughout This Changes Everything, Klein describes the climate crisis as a confrontation between capitalism and the planet. It would be more accurate to describe the crisis as a clash between the expanding demands of humankind and a finite world, but however the conflict is framed there can be no doubt who the winner will be. The Earth is vastly older and stronger than the human animal.

The Anthropocene Myth | Jacobin - 0 views

  • Who’s driving us toward disaster? A radical answer would be the reliance of capitalists on the extraction and use of fossil energy. Some, however, would rather identify other culprits.

    The earth has now, we are told, entered “the Anthropocene”: the epoch of humanity. Enormously popular — and accepted even by many Marxist scholars — the Anthropocene concept suggests that humankind is the new geological force transforming the planet beyond recognition, chiefly by burning prodigious amounts of coal, oil, and natural gas.

  • The important thing to note here is the logical structure of the Anthropocene narrative: some universal trait of the species must be driving the geological epoch that is its own, or else it would be a matter of some subset of the species. But the story of human nature can come in many forms, both in the Anthropocene genre and in other parts of climate change discourse.
  • Giving short shrift to all the talk of a universal human evildoer, she writes, “We are stuck because the actions that would give us the best chance of averting catastrophe — and would benefit the vast majority — are extremely threatening to an elite minority that has a stranglehold over our economy, our political process, and most of our major media outlets.”

  • So how do the critics respond? “Klein describes the climate crisis as a confrontation between capitalism and the planet,” philosopher John Gray counters in the Guardian. “It would be be more accurate to describe the crisis as a clash between the expanding demands of humankind and a finite world.”
  • It is perfectly logical that advocates of the Anthropocene and associated ways of thinking either champion false solutions that steer clear of challenging fossil capital — such as geoengineering in the case of Mark Lynas and Paul Crutzen, the inventor of the Anthropocene concept — or preach defeat and despair, as in the case of Kingsnorth.

Why the GOP's Attack on Obama's Climate Plan Will Probably Fail | Mother Jones - 0 views

  • But for now, there's a pretty good chance today's hearing was just a warm-up round for a much more serious fight yet to come. At this point, says Sierra Club chief counsel Joanne Spalding, the EPA's opponents "are trying to derail a train that's still in the station."
