Erica Pandey, author of Axios Finish Line<br>
</font><font face="Calibri">Destinations that were once ideal for
summer travel are now on the decline because of extreme heat and
other effects of climate change.<br>
<br>
Why it matters: Many of the world’s natural wonders have been so
severely altered by our warming planet that it’s getting too late
to save them.<br>
<br>
-- “The number one message is that nowhere is safe.” said Kate
Marvel, a senior climate scientist at Project Drawdown. “There’s
always the potential for a nasty surprise.”...<br>

Greenland’s ice sheet through millions of hairline cracks –
destabilizing its internal structure</b><br>
Published: June 29, 2023 <br>
</font> <font face="Calibri">I’m striding along the steep bank of a
raging white-water torrent, and even though the canyon is only
about the width of a highway, the river’s flow is greater than
that of London’s Thames. The deafening roar and rumble of the
cascading water is incredible – a humbling reminder of the raw
power of nature.<br>
<br>
As I round a corner, I am awestruck at a completely surreal sight:
A gaping fissure has opened in the riverbed, and it is swallowing
the water in a massive whirlpool, sending up huge spumes of spray.
This might sound like a computer-generated scene from a
blockbuster action movie – but it’s real.</font><i><font
face="Calibri">..</font></i><br>
<font face="Calibri">- -</font><br>
<font face="Calibri">Scenes like this and new research into the ice
sheet’s mechanics are challenging traditional thinking about what
happens inside and under ice sheets, where observations are
extremely challenging yet have stark implications. They suggest
that Earth’s remaining ice sheets in Greenland and Antarctica are
far more vulnerable to climate warming than models predict, and
that the ice sheets may be destabilizing from inside.<br>
- -</font><br>
<font face="Calibri">In a new paper, Dave Chandler and I demonstrate
that ice sheets are littered with millions of tiny hairline cracks
that are forced open by the meltwater from the rivers and streams
that intercept them.<br>
<br>
Because glacier ice is so brittle at the surface, such cracks are
ubiquitous across the melt zones of all glaciers, ice sheets and
ice shelves. Yet because they are so tiny, they can’t be detected
by satellite remote sensing.<br>
</font>- -<br>
Emerging processes that speed up ice loss<br>
Over the past two decades that scientists have tracked ice sheet
melt and flow in earnest, melt events have become more common and
more intense as global temperatures rise – further exacerbated by
Arctic warming of almost four times the global mean.<br>
<br>
The ice sheet is also flowing and calving icebergs much faster. It
has lost about 270 billion metric tons of ice per year since 2002:
over a centimeter and a half (half an inch) of global sea-level
rise. Greenland is now, on average, contributing around 1 millimeter
(0.04 inches) to the sea level budget annually.<br>
<br>
A 2022 study found that even if atmospheric warming stopped now, at
least 27 centimeters – nearly 1 foot – of sea level rise is
inevitable because of Greenland’s imbalance with its past two
decades of climate.<br>
<font face="Calibri">- -</font><br>
<font face="Calibri">Current climate models lowball the risks<br>
Along with other applied glaciologists, “structured expert
judgment” and a few candid modelers, I contend that the current
generation of ice sheet models used to inform the IPCC are not
capturing the abrupt changes being observed in Greenland and
Antarctica, or the risks that lie ahead.<br>
<br>
Ice sheet models don’t include these emerging feedbacks and
respond over millennia to strong-warming perturbations, leading to
sluggish sea level forecasts that are lulling policymakers into a
false sense of security. We’ve come a long way since the first
IPCC reports in the early 1990s, which treated polar ice sheets as
completely static entities, but we’re still short of capturing
reality.</font><i><font face="Calibri"><br>

<b><font face="Calibri">Widespread partial-depth hydrofractures in
ice sheets driven by supraglacial streams</font></b><i><font
face="Calibri"><br>
</font></i><font face="Calibri">Abstract<br>
</font>
<blockquote><font face="Calibri">Dramatic supraglacial lake drainage
events in Greenland and Antarctica are enabled by rapid
hydrofracture propagation through ice over 1 km thick. Here we
present a slower mode of hydrofracture, where hairline surface
fractures intersect supraglacial streams, and hypothesize that
penetration depth is critically limited by water supply and
englacial refreezing. We develop a model of stream-fed
hydrofracture, and find that under most conditions in Greenland,
2-cm-wide fractures can penetrate hundreds of metres before
freezing closed. Conditions for full-depth hydrofracture are
more restricted, requiring larger meltwater channels and/or warm
englacial conditions. Given the abundance of streams and surface
fractures across Greenland and Antarctica’s expanding ablation
zones, we propose that stream-driven hydrofractures are
ubiquitous—even where distant from supraglacial lakes and
crevasse fields. This intriguing process remains undetectable by
current satellite remote sensing, yet has two major impacts that
warrant further investigation. First, by driving widespread
cryohydrologic warming at depths far greater than surface
crevassing, it explains a consistent cold bias in modelled
englacial thermal profiles. Second, the associated reduction in
ice viscosity and increased damage accumulation act to enhance
the vulnerability of ice sheets and shelves to dynamic
instability as supraglacial drainage networks expand inland to
higher elevations.</font><br>

in part as an attempt to bring together ecology and economics – to

Our Climate Declaration - Aotearoa NZ<br>
</font><font face="Calibri">May 18, 2023<br>
We hosted a webinar by Rod Oram on Wednesday May 17.<br>
<br>
Humanity’s greatest challenge is to meet its needs within the
limits of the Living Earth. But currently both sides of that
relationship are heading fast in the wrong direction.<br>
<br>
Our population could grow by another 20 percent to some 10 billion
people by 2050; and the way we use the Earth's resources is ever
more rapidly diminishing the Earth's ability to support us and all
other forms of life.<br>
<br>
The quest for a healthy relationship between people and planet
takes many forms such as degrowth and other changes in behaviour,
economics, values, technology, and other drivers of human
activity.<br>
<br>
In this session, Rod examined the weaknesses of degrowth in
particular; and offer some other ways humanity can re-establish
its right relationship with the Living Earth.<br>

<b>Indicators of Global Climate Change</b><br>
The Indicators of Global Climate Change (IGCC) initiative is
providing updates of several key global climate indicators reported
by the Intergovernmental Panel on Climate Change (IPCC) that can
help us to understand the state of the climate system and how it is
changing.<br>
<br>
The focus is on providing up-to-date estimates of policy-relevant
global climate indicators that follow the causal chain from
emissions to warming, including greenhouse gas emissions, human
induced warming and the remaining global carbon budget.<br>
<br>
In doing so, IGCC brings together timely information that can
support effective climate decision-making in a findable, accessible,
traceable and reproducible way.<br>
<br>
The methodologies used to update the indicators are directly
traceable back to the IPCC Sixth Assessment Report (AR6). The
underpinning publication which describes these methodologies, and
also provides further context and background.<br>
<br>
IGCC is also working with the Climate Change Tracker to provide a
reliable, user-friendly platform for tracking, visualising and
understanding these indicators, aimed at policy-makers but open and
accessible to all.<br>
- -<br>
The speed and extent of climate change that the world is now
experiencing highlights the need for urgent climate action in this
critical decade.<br>
<br>
Decisions need to be based on trusted, reliable and timely
information, but when it comes to the key climate system indicators
set out in Intergovernmental Panel on Climate Change (IPCC) reports,
there is an information gap between one IPCC assessment cycle and
the next.<br>

<b>It’s Not A Climate Crisis. It’s A Climate CRIME.</b><br>
Ray Katz<br>
Calling it a crises, or worse climate “change”, protects the
criminals who are committing the most evil crime in human history.<br>
<font face="Calibri"> </font> <br>
<font face="Calibri">The post-apocalyptic sight of an orange hued
toxic film blanketing New York City was not a symptom of climate
change or even a climate crisis. True, there IS a climate crisis
but this crisis did not appear spontaneously.<br>
<br>
This crisis was a crime that was committed and the criminals are
still at large, still poisoning and cooking the Earth. They are
the “masterminds” behind the current Great Extinction.<br>
<br>
This isn’t a tragedy. It’s a CRIME. Criminals poisoned New York
City. Many of the leading criminals who are responsible live
there. For them, it may be the first time they directly saw what
they have done.<br>
<br>
It won’t be the last time. And they can’t hide behind that cloud
of smoke. The smoke exposes them.<br>
<br>
People will be asking the question: “Who did this?” And everyone
knows the answer. It has remained unspoken. We hear “it’s
complicated.” Or “we need oil”. Or, “all of us need to shrink our
carbon footprints.”<br>
</font><font face="Calibri">- -</font><br>
<font face="Calibri">Our media — enthralled by lies or paid
accomplices to the criminals — aren’t telling us much. But things
are happening. People are doing things. Children of the leading
climate criminals are pressuring their parents. And ordinary
people are talking, finding each other, starting to recognize they
have huge numbers and power.<br>
<br>
People are forming communities of activists. They are waking up.
The entire planet is like the Soviet Union in 1990. There isn’t a
visible hint of what is coming. But there is a feel to it. Despair
is real, but so is anger, frustration and a determination to not
go quietly...<br>
