*Iceberg Size of Delaware Poised to Break Off From Antarctica
<http://www.nbcnews.com/science/environment/iceberg-size-delaware-poised-break-antarctica-n703821>*
NBCNews.com - 2 hours ago
An iceberg the size of Delaware is poised to break away from
Antarctica, an event which may lead to the collapse of a massive ice
shelf on the continent, according to researchers...
Scientists say that a 1,900 square-mile section of the "Larsen C"
ice shelf is now only connected to the main body by a 12-mile
section of ice. Researchers monitoring a huge crack in the ice
discovered that it had grown rapidly during the second half of 2016
— increasing in size by 11 miles in December alone...
If the iceberg does break away, it would be one of the ten largest
ever recorded...
n November 2016, NASA scientists carrying out an airborne survey of
polar ice measured the crack in Larsen C to be about 70 miles long,
more than 300 feet wide and about a third of a mile deep.

The Very Real Threat of Trump's*Climate*Denialism
<http://www.thedailybeast.com/articles/2017/01/07/the-very-real-threat-of-trump-s-climate-denialism.html>
Daily Beast -3 hours ago
During the past few months, Scott Pruitt, Donald Trump's pick to
head the Environmental Protection Agency, Rick Perry, Trump's pick
to head the Energy Department, and Donald Trump himself have all
said that they don't believe in*climate change*. The most upsetting
part of their statements has been the misuse of the word believe.
Religion is a belief system. You have to believe that Moses parted
the Red Sea or that Lazarus was raised from the dead. Because these
phenomena violate the laws of nature, they are matters of faith....
Science, on the other hand, isn't a belief system. It's an
evidence-based system. For example, you don't have to believe in the
theory of evolution. All you have to do is examine 250,000 years of
fossil records to know that humans and apes evolved from a common
ancestor. You don't have to believe in the germ theory. All you have
to do is recognize that vaccines, antibiotics, and sanitation
programs have increased our lifespan by 30 years during the past
century. And you don't have to believe in the theory of gravity. All
you have to do is drop your pen. None of these concepts are theories
any more. They're facts supported by evidence....
Sometimes people like Donald Trump, Scott Pruitt, and Rick Perry
describe climate change as a "controversial new science." In truth,
it's not new at all. Joseph Fourier made his observations in the
early 1800s, well before Charles Darwin advanced his theory of
evolution...
...It's not too late. By turning away from fossil fuels and turning
toward renewable sources of energy like those generated by the sun,
wind, and rivers, there's still plenty of time to reverse this
trend. The Paris climate summit in 2015 and President Obama's Clean
Power Plan in the same year were good starts. And while it is
reasonable for politicians to argue whether the programs that have
been put in place have been the most efficient way to spend limited
resources, it is madness to claim that the problem doesn't exist.
The simple truth is that it will cost less money to curb CO2
emissions today than to mitigate the problems created by the
greenhouse effect tomorrow. Our politicians owe us that. If they
care at all about their legacy, they need to stop denying what is
plainly in front of them. Because, as noted by Raymond Aron, "The
judgment of history is without pity."*...
The incoming Trump administration seems to be in a competition with
itself to pretend climate change isn’t real—and that has very real
consequences.

*What's The Best Way to Convince a Climate Change Denier?
<http://www.sciencefriday.com/segments/whats-the-best-way-to-convince-a-climate-change-denier/>*
In the summer of 2015, NOAA scientists published a paper
<http://science.sciencemag.org/content/348/6242/1469> that ran
counter to one narrative on global warming: While some data seemed
to show the rate of warming had slowed or paused after 1998 and into
the beginning of the 21st century, they wrote, an update to NOAA's
influential temperature data set confirmed that warming had actually
continued at a consistent pace during that time. The paper, which
challenged the positions of climate skeptics, was politically
controversial, and led to a Congressional subpoena for the team from
Republican Lamar Smith. Now, new research
<http://advances.sciencemag.org/content/3/1/e1601207> in /Science
Advances/ echoes what NOAA asserted two years ago.

Science Daily -11 hours ago
About 15000 years ago, the ocean around Antarctica has seen an
abrupt sea level rise of several meters. It could happen again.
... ice sheets melt more strongly than when the surrounding ocean is
thoroughly mixed. This is exactly what is presently happening around
the Antarctic....
"The largest melt occurred 14,700 years ago. During this time the
Antarctic contributed to a sea level rise of at least three meters
within a few centuries."

Potential for Collapse of Key Atlantic Current Rises
<http://www.climatecentral.org/news/potential-collapse-key-atlantic-current-21024>
Climate Central -12 hours ago
The large, looping Atlantic Ocean current that keeps northwestern
Europe fairly warm and influences sea levels along the U.S. coast is
a key component of the Earth's*climate*system. But because of*global
warming*, it may be more likely to substantially*..If that current,
called the Atlantic Meridional Overturning Circulation, were to slow
down substantially, it could lead to chillier weather in northern
and western Europe, starve economically important fisheries and
cause waters to rise along the U.S. coast, leading to more so-called
*"*sunny day*"* flooding and storm surge when hurricanes come
ashore. It could also shift tropical rain belts, causing major
disruptions to regional climate in Central and South America...
The new studies factor in elements that have been missing from
previous projections of how likely the collapse of the current is.
One study factors in the melting of the Greenland Ice Sheet, which
is adding a pulse of freshwater into the North Atlantic, but is
difficult to incorporate into current climate models. The other
attempts to correct a bias in climate models that underestimates how
unstable the AMOC really is...
While neither study is close to the final word on what might happen
to this crucial current as global warming continues, the second, in
particular, *"*raises some serious concerns*"* about our
understanding and points to the need to improve models, said Tom
Delworth, a research scientist with the National Oceanic and
Atmospheric Administration....More concerning is the bias in climate
models addressed by the second study, published Wednesday in Science
Advances. Effectively, models are missing the way an initial
weakening of the current from ocean warming causes freshwater to
build up, further weakening the overturning of the circulation. This
relationship has been observed in recent direct ocean measurements,
as well as paleo data....In their simulations, that collapse caused
significant shifts in tropical rain belts and led to regional
cooling over the northern Atlantic and nearby areas. Winter
temperatures over parts of northern and western Europe were nearly
13°F (7°C) colder than present...
The results show how crucial it is to accurately represent the AMOC
in climate models, as well as to continue gathering direct
observations of the current, which began only about a decade ago,
Delworth said...
*"*We use models for making any of these projections, so the
projections are only as good as the models are,*"* he said. *"*I
suspect this will be a real emphasis of research in the next few
years.*"

'The underestimated danger of a breakdown of the Gulf Stream System'
<http://www.realclimate.org/index.php?p=19900>
posted to RealClimate.org....A new model simulation of the Gulf
Stream System shows a breakdown of the gigantic overturning
circulating in the Atlantic after a CO2 doubling.... The Atlantic
ocean circulation is relatively stable in the uncorrected model,
only declining by about 20% in response to a CO2 doubling, but in
the corrected model version it breaks down completely in the
centuries following a CO2 doubling, with dramatic consequences for
the climate of the Northern Hemisphere...
The potential instability of the Atlantic Meridional Overturning
Circulation or AMOC – commonly known as the Gulf Stream System – has
been a subject of research since the 1980s, when Wallace Broecker
warned in an essay in Nature of Unpleasant Surprises in the
Greenhouse. The reason for this was growing evidence of abrupt
climate changes in the history of the Earth due to instability of
Atlantic currents. http://www.realclimate.org/index.php?p=19900
Is the Gulf Stream System Slowing? – the Earth101 lecture
<https://www.youtube.com/watch?v=EmiVhT5cHpw>
A slowdown or even collapse of the Gulf Stream System as a result of
global warming has long been a concern of climate scientists
...Regular direct observations of this giant ocean current system do
not go back far enough to tell whether there is any long-term trend.
However, in recent years indirect evidence is mounting for a
remarkable slowdown over the 20th
Century...https://www.youtube.com/watch?v=EmiVhT5cHpw
*Global Warming Facts: Data Shows Temperature Rise Is Constant

Global warming is a reality that the world now faces. Global warming
facts has data that shows that temperature rise is constant. Another
ice age though might also be due, as scientists see ocean currents
collapsing.

Two key climate change indicators have broken numerous records
through the first half of 2016, according to NASA analyses of
ground-based observations and satellite data. Each of the first six
months of 2016 set a record as the warmest respective month globally
in the modern temperature record, which dates to 1880. Meanwhile,
five of the first six months set records for the smallest monthly
Arctic sea ice extent since consistent satellite records began in
1979. NASA researchers are in the field this summer, collecting data
to better understand our changing climate.

- from D.R. Tucker*
January 7, 1982: The New York Times reports:
"Mankind's activities in increasing the amount of carbon dioxide and
other chemicals in the atmosphere can be expected to have a
substantial warming effect on climate, with the first clear signs of
the trend becoming evident within this decade, a scientist at the
National Aeronautics and Space Administration said here today.
"The changes are in prospect because of excess carbon dioxide put
into the atmosphere as humans burn coal, gas, oil and wood and cut
forests for agriculture and other purposes. More recently there has
also been an atmospheric buildup of methane, nitrous oxide and other
chemicals as a result of agriculture and industry, said Dr. James
Hansen of the space agency's Goddard Institute for Space Studies in
New York.
"Dr. Hansen spoke at a session of the annual meeting of the American
Association for the Advancement of Science here and amplified some
of his remarks at a news conference."
