Going over GeoEngineering Climate solutions, MIT has found a mitigation method that works from space

Think of it as cool sunglasses for the planet …

As some of you may be aware, for a number of reasons * (primarily appropriate), I am a proponent of Big Science Climate Mitigation Solutions **. Well, because of this interest, Google Newsfeed just informed me about another such possible method – except that this works from space, instead of taking up valuable property here on earth.

Note: MIT itself puts this warning qualification on their proposed sunscreen solution:

It is important to note that MIT do not see this as an alternative solution to our current adapt and reduce efforts. Instead, it is a backup solution meant to help if things get out of control.

Note 2: This MIT solution depends on distributing their sunscreen solution, at the gravity-neutral L1 part of space, Lagrangian Point. Smart, it’s a similar gravity stable place that herds the James Webb Space Telescope around the sun – with a minimum of course corrections needed.

The James Webb Space Telescope stretches the horizon to our understanding.

MIT researchers believe they have discovered how to fully reverse climate change

of Joshua Hawkinsbgr.com – July 9, 2022


The idea is heavily about the creation and distribution of several thin film-like silicon bubbles. The “space bubbles” as they refer to them would be put together like a raft. When expanded in space, it will be round same size as Brazil. The bubbles would then give an additional buffer against the harmful solar radiation coming from the sun.


Researchers at MIT have adopted the same basic concept [a “cloud” of small spacecraft] and improved it, however, by replacing inflatable silicon bubbles for the spacecraft that Angel originally proposed. Being able to reverse climate change will be a big step in the right direction. However, shielding the earth from the sun’s radiation would only be a part of it. We still have to cut back on other things as well.


Scientists say we probably still need to put some kind of spacecraft out there to keep things on track. But it can give us a good chance to reverse climate change, or at least slow down change. […]

I must admit that I am a little aware of the scope of this solution. What if it filters out TOO MUCH solar radiation, is the first question that arises. But again in the pace that went, TOO MUCH CATCHED solar radiation is exactly the problem, we are facing as a technological civilization that hopes to survive after 2100. Heck, the way most climate warning models have underestimated feedback enhancement effects, when 2050 without serious societal collapse, can be a stretch.

It would be good to have such “last hope” reducing tools in your back pocket, in case everything else fails. Hopefully we will never have to distribute them on a massive scale, because governments are up to the carbon reduction challenge. Once they have done so, perhaps these successes will spur the urgency of figuring out how to stop the Methane freight train running down the timeline of global warming.

It is, after all, the governments of the world so skilled take proactive steps to solve major problems – and by that I mean, Not so much.

* Some reasons why I am an advocate for Big Science Climate Mitigation solutions:

  1. The appropriateness, our start-up time for course corrections, is starting to expire quickly.
  2. The scale of the problem is global.
  3. Most researchers are quite smart.
  4. Governments are slow to respond, especially on all scales beyond half measures.
  5. Big Science got us into this mess, Big Science might get out.
  6. Feedback loops accelerate the speed of ecosystem hazards due to climate change.

A few Big Science Climate Mitigation solutions ** that I think have benefits:

  1. Carbon capture: Mechanical trees.

  2. Carbon capture: seeding Plankton blooms.

  3. Carbon capture: Seaweed / Algae farm.
  4. Carbon capture: Scrubbing of smoke stack.
  5. Tidal power tapping

  6. Geothermal tapping.

  7. Fuel cell and battery breakthrough.

  8. Breakthrough for CO2 / methane enzyme.
  9. Massive wind farms.
  10. Massive solar farms.
  11. Massive afforestation.
  12. Think globally, shop and work locally.

We only have one planet. There is no Planet B to save us from our predicament.

Smart science just maybe.
