- Solar geoengineering technology holds possibilities and pitfalls, renowned scientist argues
Climate change can feel like an impossible crisis these days. Every week there is some new report about the irreversible damage we’re doing to our planet and the havoc it will bring to people’s lives. We all know cutting emissions is the solution, yet governments and companies seem no closer to meeting the goals that scientists say we must hit. It can feel hopeless.
There is one possible controversial solution to climate change many in the mainstream haven’t discussed. It’s so controversial, in fact, that some experts say we shouldn’t even be discussing it. But University of Chicago Professor David Keith says we need to talk about it. It’s called solar geoengineering-the process in which you reflect a small fraction of sunlight back into space using aerosols. As the founding director of the Climate Systems Engineering Initiative at UChicago, Keith is leading a team that will research solar geoengineering and other novel solutions to climate change.

How would reducing photosynthesis not cause a worldwide food shortage?
How would making the wheat belt die from heat stress not cause a worldwide food shortage. But to answer your question, so far the evidence is that we wouldn’t be doing enough srm to make crop yields any worse than they would otherwise be anyway. The evidence Actually is that crops would be protected by srm as long as we weren’t doing stupld amounts of it

Watch The Dimming film. And, What In The World Are They Spraying.
I support the Business As Usual model. Since we're on the way to collapse anyway we should do it now, rather than continue to degrade the environment for the rest of life then collapse.

God damn your georgeniring..
This is part of the answer.
This video puts the cart before the horse. You are proposing and discussing solutions before we understand the problem.
Firstly we need a study to compare the benefit of additional atmospheric CO2 in terms of worldwide agricultural production against potential adverse climate effects from increased CO2. We might seek to determine an optimum atmospheric CO2 level we want to achieve rather than the status quo. We might demand a cost benefit analysis of CO2 being reduced or increased based on empirical data rather than abstract computer modelling.
Secondly, water vapour and clouds are the largest component in determining weather. Understanding cloud formation should be the starting point of all climate science. It is unconscionable that universities have not yet determined how clouds are formed with a reference to cosmic rays and celestial events and cycles..
You think this hasn’t already been done. We already know that the excess of co2 In the atmosphere is making food less nutritious s as well as the heat is now killing crops from heat stress
@@deanfowles3707 Wrong on all counts. Firstly the studies have not been done else I would not have called for them. Second the UN and the US government have acknowledged the improved greening of the planet as CO2 levels rose
What BS about food taste less nutritious.
@@bobdeverell you arrogantly declare me wrong on all counts and clearly haven’t looked into it whatsoever
“Elevated atmospheric carbon dioxide levels negatively impact key mineral nutrients in plants, reducing the nutrition derived from consuming them, reveals a recent review article in the Trends in Plant Science Journal which summarises findings from several studies”
As for the greening of the planet yes no doubt the planet will become more green. Not the king we would want though you wouldn’t want the oceans green with slimy toxic algae blooms. Look it up it’s a distinct possibility. You also don’t want the Amazon rainforest turning into Savannah. Another thing that probably is gonna happen within a lifetime.
Basically stop being an armchair expert, stop being arrogant far beyond your capabilities, humble yourself and learn from people who do this stuff for a living.
This guy has been misleading us from the truth for years
Geoengineering refers to long-term shifts in temperatures and weather patterns.
Climate change
solution = nuclear energy
We won't stop climate even if we go net zero
Completely correct. New materials are needed to such extent as to cover the earth, I'd argue, with huge reflective capacity that can be turned on and off as needed.
If you wanted green energy tesla ram pump tesla turbine. If you are not teaching vortex mathematics you are teaching the wrong way.
