Latest studies of ocean warming and climate change

Despite the onslaught of politicians attempting to project an air of
question around man-made climate change, studies continue to emerge
proving the connection between human actions and our changing
environment. The most recent study, published in Nature Climate
Change, finds an "anthropogenic fingerprint" (human influence) on our
warming oceans.

The study, "Human-Induced Global Ocean Warming On Multidecadal
Timescales," was conducted by researchers in the U.S., Australia,
Japan and India. Based on observations of rising upper-ocean
temperatures, the researchers used improved estimates of ocean
temperatures to examine the causes of our warming ocean.

According to a Lawrence Livermore National Laboratory press release,
the study shows that over the past 50 years, observed ocean warming is
explained only when greenhouse gas increases are included in the
models.

Lead author and LLNL climate scientist Peter Gleckler said in the
press release, "The bottom line is that this study substantially
strengthens the conclusion that most of the observed global ocean
warming over the past 50 years is attributable to human activities."

Gleckler added, "Although we performed a series of tests to account
for the impact of various uncertainties, we found no evidence that
simultaneous warming of the upper layers of all seven seas can be
explained by natural climate variability alone. Humans have played a
dominant role."

Report co-author Dr. John Church explained to Australia's ABC News AM
that "Natural variability could only explain 10 percent, or
thereabouts, of the observed change."

Oceanography expert Nathan Bindoff told the news organization, "This
paper's important because, for the first time, we can actually say
that we're virtually certain that the oceans have warmed, and that
warming is caused not by natural processes, but by rising greenhouse
gases primarily." He added, "We did it. No matter how you look at it,
we did it. That's it."

The recent ocean warming study has been released on the heels of other
disturbing climate change reports.

Arctic monitoring stations are now measuring over 400 parts per
million of carbon dioxide in the atmosphere, a disturbing milestone
that far surpasses the 350 ppm mark that many scientists consider the
threshold separating safe from dangerous.

Researchers recently warned in Nature that the world is heading toward
a tipping point of disastrous consequences driven by human-led
increases in atmospheric carbon dioxide and rising global
temperatures:

"The plausibility of a planetary-scale ‘tipping point’ highlights
the need to improve biological forecasting by detecting early warning
signs of critical transitions on global as well as local scales, and
by detecting feedbacks that promote such transitions. It is also
necessary to address root causes of how humans are forcing biological
changes."

Despite the ominous findings, some politicians are still attempting to
project an element of doubt on issues surrounding human-induced
climate change. A Virginia lawmaker recently fought to omit mentions
of "climate change" and "sea level rise" from a coastal flooding
study, telling the BBC, "The jury's still out" on whether humans
contribute to global warming. Despite his claim, studies such as the
recent ocean warming one are turning in a pretty clear verdict.

Enough of this nonsense which is a product of mean spirited and narrow
minds !.

The one thing the world is heading for is a lovely orbital event where
the orbital phase of the planet puts the polar coordinates at a
maximum distance to the circle of illumination as those coordinates
act like a beacon for the orbital motion of the Earth - a lovely way
to describe why temperatures North of the Equator are on the rise
while Southern latitudes will experience a descent in the coldest days
of the June orbital period.

The transit of Venus is really a continuation of an orbital phase that
the great astronomers noticed as Venus loomed large as it approaches
the circuit of the Earth and its phases reflect its orbital position
relative to ours.So poor is astronomy presently that in an attempt to
explain the Earth's temperature fluctuations using 'tilt',they doctor
images and graphics to make it appear the Earth does not have the same
type of phases as Venus -

There are no real researchers,at least to my knowledge,climate studies
haven't even begun and the very fact that the same researchers model
planetary dynamics based on an imbalance between one 24 hour day and
one 360 degree rotation of our planet is more than adequate to call a
halt to this pernicious nonsense about 'tipping points'.

Want to use the transit of Venus information properly ?,then consider
the dynamics which are now presently turning the polar coordinates in
a circle/cycle to the central Sun and,when allied with daily rotation
at lower latitudes,creates the spectacular lengths of daylight we now
see in Northern Europe.

Actually, Gerald, it is the scale of planet alteration, over
population and depletion of natural resources that threatens
our (and other) species.

Approaching a state shift in Earth’s biosphere
http://www.nature.com/nature/journal...ture11018.html

Localized ecological systems are known to shift abruptly and irreversibly from one state to another when they are forced across critical thresholds. Here we review evidence that the global ecosystem as a whole can react in the same way and is approaching a planetary-scale critical transition as a result of human influence. The plausibility of a planetary-scale ‘tipping point’ highlights the need to improve biological forecasting by detecting early warning signs of critical transitions on global as well as local scales, and by detecting feedbacks that promote such transitions. It is also necessary to address root causes of how humans are forcing biological changes.

Astronomers have the most encompassing perspective of any researchers
into these matters and the emergence of human control over the
planet's temperature is a direct result of the extraordinary low
standards out there presently in astronomical circles.

The fact is that the primary cause of the daily and annual cycles in
temperature was discovered by Copernicus and while the daily 24 hour
temperature fluctuation cycle is straightforward enough,the annual
cycle where temperatures fluctuate with latitude and especially
latitudes towards the polar coordinates require the new approach which
introduces an additional orbital feature.This means modifying the
original approach of Copernicus which asserts a 'no tilt/no seasons'
perspective -

"..the equator and the earth's axis must be understood to have a
variable inclination. For if they stayed at a constant angle, and were
affected exclusively by the motion of the centre, no inequality of
days and nights would be observed. On the contrary,it day or the day
of equal daylight and darkness, or summer or winter, or whatever the
character of the season, it would remain identical and unchanged."
Copernicus

Copernicus is describing an equatorial climate which would result from
the daily rotation and ecliptic axes aligning whereas if they were
separated by 90 degrees,as is in the case of Uranus,the planetary
climate would be totally polar whereas the Earth has a largely
equatorial climate with just enough polar inputs to foster the cycles
of nature and the seasons of sowing and reaping we see all around us.

It is hard to know exactly what all these astronomers do day in and
day out other than act against this most ancient discipline where the
work of our ancestors is appreciated in context of their era and their
concerns.I have no doubt that using the polar coordinates as a beacon
for the orbital component of the Earth and its circle/cycle to the
central Sun has been understood,at least in outlines,but with no
reliable clearinghouse to handle a modification which is
substantive,it has been left to drift for years and that is as bad as
not being understood at all.
