So we have passed the point of atmospheric CO2 for 1.5 degrees warming and are headed to more than 2 degrees warming. I thought it would be instructive to look at what some climate scientists are predicting for more than 2 degrees warming.
A place I can put my thoughts on science, teaching and the human condition, and also occasionally attempt to influence policy makers (lots of luck!).

read an interesting article today of a way to decrease the amount

so as to decrease warming of the oceans.

MIT
Scientists Propose Space Bubbles to Reverse the Worst of Climate Change
By

The
idea is to create a really huge “raft” of silicone bubbles which if positioned
between the earth and the sun would decrease the solar radiation. I copy the
article below:
A
team of researchers at the Massachusetts Institute of Technology believe that
we can mitigate the worst of climate change with… space bubbles. They’ve
outlined a strategy in which a huge raft of bubbles, carefully positioned
between Earth and the Sun, would deflect sunlight (and thus heat) to stop further
global warming.
“Geoengineering
might be our final and only option. Yet, most geoengineering proposals are
earth-bound, which poses tremendous risks to our living ecosystem,” a web page
dedicated to the solution reads. “If we deflect 1.8% of incident solar
radiation before it hits our planet, we could fully reverse today’s global
warming. The bubble array would be made of inflatable shields of thin silicon
or another suitable material, according to the team. The bubble cluster would
be placed in outer space at a Lagrange Point, where the Sun’s and Earth’s
gravitational pulls create a stable orbit. The researchers also said that if
the plan becomes a reality in the future, the completed array would be roughly
the size of Brazil.
They
admitted that one of the main concerns with their proposal would be the
logistics of fabricating a large film, transporting it into space, and then
unfolding it to form the bubble raft. They suggested fabricating the spheres in
outer space to minimize shipping costs.
“[The]
bubbles can be intentionally destroyed by breaking their surface equilibrium,
this would make the solar geoengineering solution fully reversible and
significantly reduce space debris,” the MIT researchers wrote in a statement. They
also pointed to the difficulties of maintaining the integrity of the bubble
shield. “Effective replenishment rate will be studied to ensure the shield
maintains its size, together with strategies to guarantee a smooth end-of-life
transition.”
This
isn’t the first space-based solution proposed to block the Sun in some way. In
2017, a study suggested an Earth-sized shield to stop solar flares from messing
with our communication systems.
But
why go to such extremes (which surely have unforeseen risks and consequences)?
The MIT researchers described the proposed space bubbles as something to
supplement other climate change mitigation efforts, but it is still a
speculative plan, and other solutions currently exist. If the political will,
funding, and technology is available for these high-tech solutions, the same
should be possible for much more reasonable solutions, like putting a stop new
oil and gas drilling projects.
According
to the Intergovernmental Panel on Climate Change, we only have a a jarring three-year
deadline to curb our emissions and stop climate disaster. Our current fossil
fuel infrastructure is enough to push us over that edge, and we can prevent
that by keeping the oil in the ground and working to decarbonize our systems.
People
in the U.S. are already suffering the consequences of years of emissions. Some
of the largest water reservoirs on the West Coast and in the Southwest are
drying up. Several states are experiencing a dangerous heatwave right now, and
cities all over the country are implementing water restrictions due to
widespread drought. We don’t exactly have the time to tinker around in space,
hope that it works, and then continue to pump greenhouse gases into the
atmosphere.
I
actually suggested a similar idea several years ago in my Blog (Larry Simpson’s
Thoughts and Musings), based on an article by a graduate student.
I copy my old Blog posting below.
“Dr.
Lagrange Would Be Smiling
In
the late 1700's, the mathematicians, Leonhard Euler and Joseph Lagrange,
discovered that there are five points where the gravitational attractions of
two astronomical bodies exactly cancel out. Actually, due to the elliptical
orbit of the earth, these are "areas" rather than points. A diagram
of the five Earth-Sun Lagrange sites is shown below (from Wikipedia).
These
sites are not just of academic interest, but may actually be the saviors of the
world! This is a rather presumptuous statement, even for a molecular biologist
like myself, so let me try to explain. In 1958 the Polish astronomer, Kordylewski,
observed the presence of large very faint clouds of dust at two of these
Lagrange sites. And of course there have been many science fiction books using
Lagrange sites for a variety of fantastic operations..
And
now the plot thickens. A few months ago I read an article about a proposal by
Russel Bewick, a graduate student, and his collaborators in a paper in the
Journal of Space Sciences which is a respected journal. They propose to drag a
fairly large asteroid such as Ganemede 1036 to the L1 Lagrange point, and to
attach a “mass-driver” to generate huge clouds of dust. These would encompass
around 1600 km and would be prevented from wandering off by the gravitational
pull of the asteroid. Bewick calculated that this cloud could produce a 1.6%
reduction in the sunlight reaching the earth, too little to be actually
detected by eye. But enough to decrease the temperature of the earth by around
2 degrees C and eventually ameliorate the effects of global warming.
When
I read this I said to myself that this is a great idea but not feasible. The
technology does not yet exist and the possible dangers abound such as making an
error (ie using English and not Metric units, as was actually done for a Mars
lander some time ago!) and thereby letting the asteroid hit the earth and
destroy 90% of the life as happened 60 million years ago in the Yucatan. But by
the time we have this technology the accumulative effects of global climate
change may be so horrible that this may be a chance worth taking to save our
civilization! “
In
fact NASA has actually proposed an asteroid capture project for developing a
way to nudge the asteroid and eliminate the possibility of it hitting the
earth. The same method could possibly be used to capture a large asteroid and
move it to the L1 Lagrange point. Of course decreasing the heating of the ocean
would not solve all the other problems of climate change, such as acidification
of the oceans and melting the ice in the artic and Antarctic and causing
droughts and flooding. But it may be a start.
Secret Service deletes text messages from Jan. 5 and 6
You have to admit that the first time you read that the
Secret Service guarding Trump deleted multiple text messages sent on January
5th and 6th , you said to yourself “Secret Service - What the fuck?”
OK Here is my take on this:
We know that Trump almost strangled an agent who refused to drive him back to
the capital which was in the throes of a pro-Trump riot at that time. We also
know that Trump had put his loyalist agent, Tony Ornato, as Deputy Chief of
Staff. And we know that Ornato told people that Hutchinson’s account of this
episode “was not consistent with his understanding of the incident”. I assume
this means that he thinks that Trump did not try to strangle the agent. Another
fact we know is that V.P. Pence refused to enter the limo in the basement of
the capital and be driven by the Secret Service agents to a military base,
since he wanted to remain in the capital for the certifications of the true
electors.
Now think about what would have happened if Pence had been driven to a military
base at that time. The electors would not have been certified and Trump’s
people may have hanged Pence since he had no “spine”. In any case, this was the
Eastman and Giuliani scenario in which Pence did not certify the true electors
leading to the states.
The Eastman Proposal
1. VP Pence, presiding over the joint session (or Senate Pro Tempore Grassley,
if Pence recuses himself), begins to open and count the ballots, starting with
Alabama (without conceding that the procedure, specified by the Electoral Count
Act, of going through the States alphabetically is required).
2. When he gets to Arizona, he announces that he has multiple slates of
electors, and so is going to defer decision on that until finishing the other
States. This would be the first break with the procedure set out in the Act.
3. At the end, he announces that because of the ongoing disputes in the 7
States, there are no electors that can be deemed validly appointed in those
States. That means the total number of “electors appointed” – the language of
the 12th Amendment -- is 454. This reading of the 12th Amendment has also been
advanced by Harvard Law Professor Laurence Tribe (here). A “majority of the
electors appointed” would therefore be 228. There are at this point 232 votes
for Trump, 222 votes for Biden. Pence then gavels President Trump as
re-elected.
4. Howls, of course, from the Democrats, who now claim, contrary to Tribe’s
prior position, that 270 is required. So Pence says, fine. Pursuant to the 12th
Amendment, no candidate has achieved the necessary majority. That sends the
matter to the House, where the “the votes shall be taken by states, the
representation from each state having one vote.” Republicans currently control
26 of the state delegations, the bare majority needed to win that vote.
President Trump is re-elected there as well.
5. One last piece. Assuming the Electoral Count Act process
is followed and, upon getting the objections to the Arizona slates, the two
houses break into their separate chambers, we should not allow the Electoral
Count Act constraint on debate to control. That would mean that a prior
legislature was determining the rules of the present one — a constitutional
no-no (as Tribe has forcefully argued). So someone – Ted Cruz, Rand Paul, etc.
– should demand normal rules (which includes the filibuster). That creates a
stalemate that would give the state legislatures more time to weigh in to
formally support the alternate slate of electors, if they had not already done
so.
6. The main thing
here is that Pence should do this without asking for permission – either from a
vote of the joint session or from the Court. Let the other side challenge his
actions in court, where Tribe (who in 2001 conceded the President of the Senate
might be in charge of counting the votes) and others who would press a lawsuit
would have their past position -- that these are non-justiciable political
questions – thrown back at them, to get the lawsuit dismissed. The fact is that
the Constitution assigns this power to the Vice President as the ultimate
arbiter. We should take all of our actions with that in mind.
This suggests that the Secret Service agents did not want Biden to become
President and that Trump should! Voila - a coup has succeeded and democracy is
dead.!
