The Rebrighten organisation promotes urgent action to rebrighten and cool the Earth by reflecting more sunlight, primarily using Marine Cloud Rebrightening (MCRB), alongside ongoing efforts to bring emissions to zero and remove greenhouse gases from the atmosphere.

As a not-for-profit organization, Rebrighten.org is dedicated to researching, promoting, and deploying MCRB as a rapid, effective, and safe method to reverse global warming. We aim to raise the necessary funds to demonstrate the viability of MCRB, complementing broader efforts to mitigate warming by reducing and removing greenhouse gases.
