Hello and welcome back to our weekly climate newsletter.
Scientists are working on an unprecedented and controversial plan aimed at limiting the effects of the climate crisis.
They would shoot tiny reflective particles into Earth's atmosphere. The the particles would then bounce the sun's warming rays back into space.
The idea is that the action would help to reduce global temperature and slow ice melt - although it does not address the root causes of climate change.
The method is known as "solar geoengineering," and some environmental groups and scientists argue that it would take decades to perform or lead to unintended consequences for Earth and its inhabitants.
But, U.S.-Israeli start-up Stardust Solutions has raised tens of millions of dollars to pursue the technique.
Stardust Solutions co-founder Yanai Yedvab told The Independent that he was inspired by how the world came together to address the hole in the ozone layer in the 1980s.
He asserted that the current state of the planet requires rapidly exploring all available techniques.
"Given the escalating crisis it would be irresponsible not to do the work now to make sure that governments and the international community have all options to save lives and prevent additional disasters," Yedvab wrote in an email.
"The last thing anyone who takes this crisis seriously should want is for governments to realize in a decade that they need to deploy SRT [sunlight reflection technology] and for the research, engineering, and de-risking not to be complete."
