*Climate change upends summer travel*
Erica Pandey, author of Axios Finish Line
Destinations that were once ideal for summer travel are now on the 
decline because of extreme heat and other effects of climate change.

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.

-- “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.”...

*Meltwater is hydro-fracking Greenland’s ice sheet through millions of 
hairline cracks – destabilizing its internal structure*
Published: June 29, 2023
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.

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./../
- -
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.
- -
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.

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.
- -
Emerging processes that speed up ice loss
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.

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.

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.
- -
Current climate models lowball the risks
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.

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./

*Widespread partial-depth hydrofractures in ice sheets driven by 
supraglacial streams*/
/Abstract

    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.

/[ What are our long term goals?  How much can we influence physics of 
our environment?  Does economics have any power to do that?]/
*What Is Ecological Economics?*
Dan O'Neill
May 25, 2021  Ecological Economics
What is ecological economics, and how does it differ from mainstream (or 
neoclassical) economics? Ecological economics began in part as an 
attempt to bring together ecology and economics – to bridge the gap 
between a natural and social science. Today it a transdisciplinary field 
that covers topics from degrowth to the Doughnut of social and planetary 
boundaries. In this short lecture, I discuss the history, fundamental 
vision, and modern focus of ecological economics.

*The Limits of Degrowth | Webinar Recording*
Our Climate Declaration - Aotearoa NZ
May 18, 2023
We hosted a webinar by Rod Oram on Wednesday May 17.

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.

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.

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.

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.

*Indicators of Global Climate Change*
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.

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.

In doing so, IGCC brings together timely information that can support 
effective climate decision-making in a findable, accessible, traceable 
and reproducible way.

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.

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.
- -
The speed and extent of climate change that the world is now 
experiencing highlights the need for urgent climate action in this 
critical decade.

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.

*It’s Not A Climate Crisis. It’s A Climate CRIME.*
Ray Katz
Calling it a crises, or worse climate “change”, protects the criminals 
who are committing the most evil crime in human history.

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.

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.

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.

It won’t be the last time. And they can’t hide behind that cloud of 
smoke. The smoke exposes them.

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.”
- -
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.

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...
