/ *A Severe Drought Pushes an Imperiled Amazon to the Brink*
The rainforest holds a fifth of the world’s fresh water, but 
deforestation, dwindling rain and unrelenting heat are sucking it dry.

The planet’s biggest freshwater tank is in trouble.

The Amazon rainforest, where a fifth of the world’s freshwater flows, is 
reeling from a powerful drought that shows no sign of abating.

Likely made worse by global warming and deforestation, the drought has 
fueled large wildfires that have made the air hazardous for millions of 
people, including Indigenous communities, while also drying out major 
rivers at a record pace.

One major river reached its lowest level ever documented on Monday, 
while others are nearing records, suffocating endangered pink dolphins, 
shutting down a major hydropower plant and isolating tens of thousands 
living in remote communities who can only travel by boat...
- -
The drier conditions are accelerating the destruction of the world’s 
largest and most biodiverse rainforest where parts have started to 
transform from humid ecosystems that store huge amounts of heat-trapping 
gases into drier ones that are releasing the gases into the atmosphere. 
The result is a double blow to the global struggle to fight climate 
change and biodiversity loss.

“This is a catastrophe of lasting consequences,” Luciana Vanni Gatti, a 
scientist at Brazil’s National Institute of Space Research who has been 
documenting changes in the Amazon. “The more forest loss we have, the 
less resilience it has.”

Recent studies have shown that climate change, deforestation and fires 
have made it harder for the Amazon to recover from severe droughts...
- -
Drying rivers are also a blow to the region’s economy. Barges that move 
corn bound for China and other countries were forced to reduce their 
cargo by half along an important river this month because the water was 
too shallow, and the erosion of a riverbed caused one port to collapse.

The Amazon’s rivers also fuel power plants that produce over a 10th of 
Brazil’s electricity and the lack of rain led one power plant to shut down.

Similar drought conditions were documented in 2015, contributing to the 
Amazon’s worst fire season on record. But scientists expect this drought 
to be even more devastating because the Atlantic Ocean is warmer and El 
Niño hasn’t yet reached its peak.

“This is just the beginning,” Dr. Gatti, the scientist, said.

On a recent afternoon, heavy clouds darkened the skies over the 
riverside village of Boca do Mamirauá. People scrambled to grab buckets, 
ready to fill them with rainwater. But the ominous clouds passed 
quickly. “Not a single drop,” Ms. Martins, the community leader, said.

“We’re just praying for the rain to come.”

*Arctic 21: Current State of Sea Ice Cover*
International Cryosphere Climate Initiative
Oct 6, 2023
Last month, Antarctica's maximum sea ice extent hit a record-breaking 
low. At the same time,, the Arctic experienced its sixth lowest minimum 
of sea ice since satellite records began in 1979. Scientists raise 
concern that the effects of climate change are now threatening sea ice 
in both poles; Antarctica might not be as invulnerable as previously 
thought. Dr. Walt Meier, Senior Research Scientist at the National Snow 
and Ice Data Center (NSIDC), summarizes the latest sea ice observations.

This Arctic 21 session was moderated by Pam Pearson, Executive Director, 
ICCI.

Presentations include:
A "Normal Low" Arctic Minimum, and A "Record Low Minimum" Antarctic Maximum

*A Greenhouse Effect Warning from 1983*
by soarbird
Community (This content is not subject to review by Daily Kos staff 
prior to publication.)
Thursday, June 21, 2012
While cleaning out my office the other day, I found a yellowed newspaper 
clipping with the headline, "Greenhouse effect viewed with alarm."    
The article was dated Oct. 18, 1983.  Check it out below the fold:

WASHINGTON  (AP) --  A potentially catastrophic warming of the Earth 
will start in the 1990s, disrupting food production and raising coastal 
waters as the polar icecaps melt, the federal government said in a 
report released today.

The study by the Environmental Protection Agency said the climatic 
changes from the so-called “greenhouse effect” are unavoidable and 
warned that the United States and other countries must begin searching 
now for ways to mitigate the impact.

The report, titled “Can We Delay a Greenhouse Warming?” concluded that 
even as drastic and unlikely a step as a total ban on coal burning would 
delay by only 15 years a 3.6 degree increase in average worldwide 
temperatures.

While other government studies have warned that the greenhouse effect 
was a potential problem, the EPA report is the first to state with 
certainty that the warming will occur no matter what.

The EPA study is based on earlier projections by the National Academy of 
Sciences that a doubling of carbon dioxide in the air – which could 
occur by the middle of the next century – would raise present world 
temperatures within a range of 2.7 degrees to 8.1 degrees Fahrenheit.

This result is known as the greenhouse effect because carbon dioxide 
acts like the glass in a greenhouse allowing the sun’s warming rays to 
reach earth but not allowing the heat to escape.

This is an amazingly unbalanced article by 2012 standards. Clearly, the 
denialists weren't yet active in 1983, and climate scientists still felt 
free to draw bold conclusions.  Imagine stating with certainty that "the 
warming will occur no matter what," and in the 1990s, no less!  These 
days, by the third paragraph at the very latest, the article would say, 
"Other scientists, however, disagree.  Joe Blah, of the Climate Truth 
Institute, says, "The evidence does not support such a conclusion.  
Drill, baby, drill!  And furthermore, blah blah!"

The well-funded denialist movement has done a splendid job spreading 
lies and confusion, preventing effective action, to the point that many 
observers, including myself, view the situation as irredeemable.  
Opinions among the "reality-based community" still vary widely, but it 
will be only a very few more years before the climate scientists have 
accumulated enough data to start projecting the consequences of the 
ever-increasing Arctic methane release.  Then, perhaps, we can start to 
achieve some kind of consensus about what we are really up against.

This is my first diary under this moniker, though I have been reading 
DKos regularly since the spring of 1993, just before the war.  (The 
status I would have if I had registered a username back then!)  I was 
once a fledgling planetary astronomer in the 1960s, doing research on 
weather patterns on the planet Jupiter, so I have always had a planetary 
mindset and have always viewed Earth in planetary terms.  I totally 
bought the Whole Earth Catalog "whole systems" approach.  In my 
estimation, we actually passed the point of no return 20 years ago.  
This conclusion has seemed inescapable to me ever since the early 
1990s.  Since then I have been asking myself, "OK, if this is true, then 
now what?"  Some day I'll probably write something about this subject.  
It's important to remember that we're no more doomed now that we ever 
were.  Only the time scale has changed.

*Early climate change consensus at the National Academy: the origins and 
making of "Changing Climate"*

    Abstract
    The 1983 National Academy of Sciences report entitled "Changing
    Climate," authored by a committee of physical and social scientists
    chaired by William Nierenberg, was an early comprehensive review of
    the effects of human-caused increases in the levels of atmospheric
    CO2. Study of the events surrounding the committee's creation,
    deliberations, and subsequent report demonstrates that the
    conclusions of the report were the consensus of the entire committee
    and in line with the scientific consensus of the time. This result
    contraverts a 2008 paper in which Naomi Oreskes, Erik M. Conway, and
    Matthew Shindell asserted that the report contradicted a growing
    consensus about climate change, and that Nierenberg for political
    reasons deliberately altered the summary and conclusions of the
    report in a way that played down the concerns of the other physical
    scientists on the committee. Examining the production of the report
    and contextualizing it in contemporaneous scientific and political
    discussion, we instead show how it was a multi-year effort with work
    divided among the various members of the committee according to
    their expertise. The synthesis and conclusions were expressly a
    joint statement of the committee and were consistent with other
    assessments of that time expressing deep concern over the potential
    issues while stopping short of recommending major policy changes due
    to the uncertainties, and to a lack of good alternatives.
