E continua ... O ensino da ciência nos EUA, mais estudos, e o metano, ou como Krugman poderia dizer: scary things, indeed
O ensino da ciência nos EUA:
'Darwin Foes Add Warming to Targets' by Leslie Kaufman - The New York Times - RichardDawkins.net:
"Critics of the teaching of evolution in the nation’s classrooms are
gaining ground in some states by linking the issue to global warming,
arguing that dissenting views on both scientific subjects should be
taught in public schools.
In Kentucky, a bill recently introduced in the Legislature would
encourage teachers to discuss “the advantages and disadvantages of
scientific theories,” including “evolution, the origins of life, global
warming and human cloning.” [...]
Last year, the Texas Board of Education adopted language requiring that
teachers present all sides of the evidence on evolution and global
warming. [...]
The linkage of evolution and global warming is partly a legal strategy:
courts have found that singling out evolution for criticism in public
schools is a violation of the separation of church and state. By
insisting that global warming also be debated, deniers of evolution can
argue that they are simply championing academic freedom in general. [...]"

Leading article: Climate change is not a matter of faith - Leading Articles, Opinion - The Independent:
"If opinion polls are right, fewer people 'believe' in climate change
now than a few months ago, prior to the leak of emails from the
University of East Anglia and the emergence of embarrassing errors in
one of the reports of the Intergovernmental Panel on Climate Change.
The science of global warming, it seems, has taken a severe hit in
terms of the public's credulity.
Yet as the latest scientific research makes clear, the evidence is, if
anything, stronger than it ever was about the role of humans in the
observable increase in global temperatures seen over the past
half-century. For scientists it is not a question of 'belief', it is a
question of observable fact and reasonable inference based on a wealth
of scientific data. The latest study by an international team led by
the Met Office's Hadley Centre reaffirms this position. The world is
warming, it is observed on every continent, and there is no natural
explanation that can account for it."

Arctic Seabed Methane Stores Destabilizing? - Grasping Reality with All Six Feet:
"Matthew Yglesias tells us to go read: Arctic Seabed
Methane Stores Destabilizing: It’s a good thing this is all part of
some giant conspiracy, because if I thought scientists at the
University of Alaska were undertaking good-faith scientific research
I’d be really worried about this: A section of the Arctic Ocean
seafloor that holds vast stores of frozen methane is showing signs of
instability and widespread venting of the powerful greenhouse gas,
according to the findings of an international research team led by
University of Alaska Fairbanks scientists Natalia Shakhova and Igor
Semiletov. [...]"
Study Says Undersea Release of Methane Is Under Way - NYTimes.com:
"Climate scientists have long warned that global warming could unlock
vast stores of the greenhouse gas methane that are frozen into the
Arctic permafrost, setting off potentially significant increases in
global warming.
Now researchers at the University of Alaska, Fairbanks, and elsewhere
say this change is under way in a little-studied area under the sea,
the East Siberian Arctic Shelf, west of the Bering Strait."
Methane releases from Arctic shelf may be much larger and faster than anticipated|Climate Ark:
"A section of the Arctic Ocean seafloor that holds vast stores of
frozen methane is showing signs of instability and widespread venting
of the powerful greenhouse gas, according to the findings of an
international research team led by University of Alaska Fairbanks
scientists Natalia Shakhova and Igor Semiletov.
The research results, published in the March 5 edition of the journal
Science, show that the permafrost under the East Siberian Arctic Shelf,
long thought to be an impermeable barrier sealing in methane, is
perforated and is leaking large amounts of methane into the atmosphere.
Release of even a fraction of the methane stored in the shelf could
trigger abrupt climate warming."
Mas, talvez, não haja [para já?] razões para entrar em pânico - atenção, que é uma atrás de outra, e há sempre as fotografias como as apresentadas acima:
The Heat Over Bubbling Arctic Methane - Dot Earth Blog - NYTimes.com:
"[...] But are these emissions new, or simply newly observed? Does this mean
that the Arctic system is coming unglued, and that a great outpouring
of this heat-trapping gas is about to upend the global climate system?
Despite portentous headlines — including one on the news release from
the University of Alaska, Fairbanks, saying “ Arctic seabed methane
stores destabilizing…” — there is no evidence (yet) that what is
happening is fundamentally new or destabilizing, at least according to
some of the scientists most closely tracking levels and sources of this
gas from the poles to the tropics.[...]"
