<b>All-Time Records' Possible As Heat Wave Hits SoCal This Labor Day
Weekend</b><br>

<b>As second heat wave sears California, experts say health impacts
will worsen with climate change</b><br>
By TONY BARBOZA<br>
SEP. 5, 2020 <br>
As the second major heat wave in weeks bears down on Southern
California, experts and authorities are warning the public to take
seriously the health dangers of extreme temperatures that are only
getting worse due to climate change.<br>
<br>
If the past is any guide, Los Angeles will see a spike in 911 calls,
emergency room visits and deaths during a powerful heat spell that’s
expected to peak Sunday, with highs between 110 and 120 hitting
inland valleys and 95 to 105 degrees along the coast.<br>
<br>
"Heat of this magnitude is rare, dangerous and very possibly
deadly," the National Weather Service warned. Temperatures will
remain unusually warm overnight -- in the mid-70s and 80s --
"creating a dangerous situation where it will be difficult to cool
off without air conditioning."<br>
<br>
Wildfires, elevated smog levels and possible power outages may pose
additional threats. The pandemic, meanwhile, could make this Labor
Day weekend especially deadly, as coronavirus restrictions have
closed many of the cooled indoor spaces that usually offer relief...<br>

<b>Ocean carbon uptake widely underestimated</b><br>
by University of Exeter<br>
The world's oceans soak up more carbon than most scientific models
suggest, according to new research.<br>
Previous estimates of the movement of carbon (known as "flux")
between the atmosphere and oceans have not accounted for temperature
differences at the water's surface and a few metres below.<br>
<br>
The new study, led by the University of Exeter, includes this--and
finds significantly higher net flux of carbon into the oceans.<br>
<br>
It calculates CO2 fluxes from 1992 to 2018, finding up to twice as
much net flux in certain times and locations, compared to
uncorrected models.<br>
<br>
"Half of the carbon dioxide we emit doesn't stay in the atmosphere
but is taken up by the oceans and land vegetation 'sinks'," said
Professor Andrew Watson, of Exeter's Global Systems Institute.<br>
<br>
"Researchers have assembled a large database of near-surface carbon
dioxide measurements--the "Surface Ocean Carbon Atlas"
(<a class="moz-txt-link-freetext" href="http://www.socat.info">http://www.socat.info</a>) - that can be used to calculate the flux of
CO2 from the atmosphere into the ocean.<br>
<br>
"Previous studies that have done this have, however, ignored small
temperature differences between the surface of the ocean and the
depth of a few metres where the measurements are made.<br>
<br>
"Those differences are important because carbon dioxide solubility
depends very strongly on temperature.<br>
<br>
"We used satellite data to correct for these temperature
differences, and when we do that it makes a big difference--we get a
substantially larger flux going into the ocean.<br>
<br>
"The difference in ocean uptake we calculate amounts to about 10 per
cent of global fossil fuel emissions."<br>
<br>
Dr. Jamie Shutler, of the Centre for Geography and Environmental
Science on Exeter's Penryn Campus in Cornwall, added: "Our revised
estimate agrees much better than previously with an independent
method of calculating how much carbon dioxide is being taken up by
the ocean.<br>
<br>
"That method makes use of a global ocean survey by research ships
over decades, to calculate how the inventory of carbon in the ocean
has increased.<br>
<br>
"These two 'big data' estimates of the ocean sink for CO2 now agree
pretty well, which gives us added confidence in them."<br>
<br>
The paper, published in Nature Communications, is entitled: "Revised
estimates of ocean-atmosphere CO2 flux are consistent with ocean
carbon inventory."<br>

A Collection of Surface Ocean CO₂ Observations<br>
Quality Controlled by the Science Community<br>
<b>SOCAT version 2020 is released!</b><br>
The Surface Ocean CO₂ Atlas (SOCAT) is a synthesis activity for
quality-controlled, surface ocean fCO₂ (fugacity of carbon dioxide)
observations by the international marine carbon research community
(>100 contributors). SOCAT data is publicly available,
discoverable and citable. SOCAT enables quantification of the ocean
carbon sink and ocean acidification and evaluation of ocean
biogeochemical models. SOCAT, which celebrated its 10th anniversary
in 2017, represents a milestone in biogeochemical and climate
research and in informing policy.<br>
<br>
SOCAT data are released in versions. Each succeeding version
contains new data sets as well as updates of older ones. The first
version of SOCAT was released in 2011, the second and third version
followed biennially. Automation allowed annual public releases since
version 4. The latest SOCAT version (version 2020) has 28.2 million
observations from 1957 to 2020 for the global oceans and coastal
seas. Calibrated sensor data are also available.<br>
<br>
SOCAT version 2020 was released on the 16th of June 2020, containing
data submitted on or before 15th of January 2020. Data submissions
for the next version are welcome at any time, and will be included
in the next SOCAT release in 2021.<br>

<b>Atlantification of the Arctic Ocean from Ongoing Sea Ice
Annihilation, and Risks of a Slowing AMOC</b><br>
Sep 5, 2020<br>
Paul Beckwith<br>
In this second of a new series of Arctic sea ice demise videos I
chat about the demise of the slushy in the Arctic Ocean. We are
nearing the yearly minimum, with only a few weeks of melt remaining,
and it is really coming down to the wire as to whether or not we
will set a new record, beating out 2012 or being a close second. In
2012 we had solid ice remaining, whereas this year we only have an
ocean of slushy thin ice cubes remaining. This ice is moving faster
than before, and since the surface is rougher it is easier for the
wind to grab it and set it in motion, and the IceSat is able to
detect waves from far away storms propagating under the ice further
sloshing it around and mixing the colder near freezing surface water
with warmer saltier Atlantic water from below, leading to so called
"Atlantification" of the surface water. In this video series I
discuss in detail the recent peer reviewed scientific papers on how
Atlantic Water (dense, warmer water a couple hundred of meters below
the sea ice) has moved within 80 meters of the bottom of the sea ice
in the Eastern Euro Basin, and will likely keep the ocean from
freezing up there in the winter. The heat in their Atlantic Water is
enough to completely melt out the entire Arctic Ocean ice three or
four times over, as it eventually makes it near the surface over the
entire basin. This already happens in the Barents Sea region, and is
spreading eastward into the rest of the Arctic. I will also discuss
how the so called "chimneys" where the Arctic Ocean water descends
to complete the AMOC (Arctic Meridional Overturning Circulation),
and how this process is being disrupted by Atlantification, thereby
weakening the thermohaline process leading is closer us closer to a
complete shutoff and then redistribution of global ocean circulation
patterns. Wow!!<br>
