*Climate change: IPCC scientists to examine carbon removal in key report*
By Matt McGrath - 3-21-2022
Environment correspondent
UN scientists are likely to weigh up technology to remove CO2 from the
atmosphere, as they gather to finalise a key report.
This idea will be one of many solutions considered over the next two
weeks by the Intergovernmental Panel on Climate Change (IPCC).Also in
attendance will be government officials from all over the world, who
will need to approve every line in the summary report...- -
This new study will be the third of three important reports from the
IPCC issued over the past eight months. The previous two have looked at
the causes and impacts of climate change, but this one will focus on
mitigation - or what we can do to stop it.
This essentially means that researchers will look at how we can reduce
the amount of warming gases that are emitted from human activities...
- -
"The report was scoped out to cover the full spectrum of carbon dioxide
removal approaches, which vary absolutely hugely, and the carbon dioxide
that is removed can end up in very different stores and in very
different places. So it was within the scope of the report to cover the
whole lot, basically."...
- -
The kind of carbon removal approaches the report will consider will
likely include tree planting and agriculture, as well as the more
advanced technological approaches that use large machines to remove the
carbon from the air.
They will also look at combined approaches, where land is used to grow
crops which can be burned for energy while the carbon is captured and
buried.
The use of these types of technology is controversial. Campaigners
express doubts that they can be made to work economically and there are
also concerns that technology could be seen as an excuse not to make the
major changes in energy production that are needed.
Scientists though say that the situation is now so serious that carbon
dioxide removal will be needed in addition to massive cuts in emissions
and not as a substitute for them.
What ultimately emerges in the short summary for policymakers that will
be published in two weeks, will depend on delicate negotiations with
government representatives from 195 countries.
Researchers and officials will work through the summary line by line to
agree the final text.

*International Sea Level Satellite Takes Over From Predecessor*
Sentinel-6 Michael Freilich, the newest addition to a long line of
ocean-monitoring satellites, becomes the reference satellite for sea
level measurements.
On March 22, the newest U.S.-European sea level satellite, named
Sentinel-6 Michael Freilich, became the official reference satellite for
global sea level measurements. This means that sea surface height data
collected by other satellites will be compared to the information
produced by Sentinel-6 Michael Freilich to ensure their accuracy.
Launched from Vandenberg Air Force Base in November 2020, the satellite
is continuing a nearly 30-year legacy started by the TOPEX/Poseidon
satellite, which began its mission to measure sea surface height in the
early 1990s. A series of successor satellites have carried on the effort
since then, with Sentinel-6 Michael Freilich being the most recent. Its
twin, Sentinel-6B, is slated to launch in 2025...
- -
JPL, a division of Caltech in Pasadena, contributed three science
instruments for each Sentinel-6 satellite: the Advanced Microwave
Radiometer, the Global Navigation Satellite System - Radio Occultation,
and the Laser Retroreflector Array. NASA also contributed launch
services, ground systems supporting operation of the NASA science
instruments, the science data processors for two of these instruments,
and support for the U.S. members of the international Ocean Surface
Topography Science Team.

/[ classic NASA video explains measuring sea level rise - expect a
"floodier future" ]/
*High Tide Flooding*
Nov 5, 2020
NASA Goddard
Sea level rise is often spoken of in future terms, including projections
for impacts we’re likely to see by the end of the century. But in many
communities in the U.S., sea level rise is already a factor in people’s
lives in the form of high-tide flooding. Also known as sunny day or
nuisance flooding, this flooding can occur when slightly higher sea
levels – due to melting glaciers and ice sheets, as well as the water in
the oceans expanding when it gets warmer – meet a particularly high tide
or moderate onshore breeze.
We visit Annapolis, Maryland, a state capitol, home of the U.S. Naval
Academy, and seaside tourist town that has seen a dramatic increase in
floods in recent years. Waters sometimes breach flood walls, or more
often, back up through storm sewers to flood nearby streets. City
engineers and a Naval Academy team, working with data from NOAA and
NASA, are already working on flood mitigation efforts.
Annapolis is not alone in its planning for a more flood-prone future.
Cities like Boston; New York; Philadelphia; Norfolk, Virginia;
Charleston, South Carolina; Savannah, Georgia; and Miami are also faced
with increased flooding or flood potential.

*This is what sea level rise will do to coastal cities*
Apr 23, 2019
Verge Science
Sea level rise is already redrawing coastlines around the world. What
happens when the coast retreats through a major city? We look at how the
world map will change in the year 2100, and what coastal cities can do
to defend themselves.
Correction: An early version of this video suggested that researchers
expect to see four feet of sea level rise by the end of the century.
While researchers do expect to see at least that level of sea level rise
in the future, the exact timing is difficult to project. We regret the
error.

*March 24, 2014*
The New York Times reports:
"It is a danger hidden beneath the streets of New York City, unseen
and rarely noticed: 6,302 miles of pipes transporting natural gas.
"Leaks, like the one that is believed to have led to the explosion
that killed eight people in East Harlem this month, are startlingly
common, numbering in the thousands every year, federal records show.
"Consolidated Edison, whose pipes supplied the two buildings leveled
by the explosion, had the highest rate of leaks in the country among
natural gas operators whose networks totaled at least 100 miles,
according to a New York Times analysis of records collected by the
federal Department of Transportation for 2012, the most recent year
data was available.
"The chief culprit, according to experts, is the perilous state of
New York City’s underground network, one of the oldest in the
country and a glaring example of America’s crumbling infrastructure."
