Project Earth is a 2008 reality TV series, hosted by Kevin O'Leary, Jennifer L. Languell, and Mocean Melvin, on the Discovery Channel in which several groups of scientists experiment with radical ideas to slow and/or stop global warming using geoengineering methods.

The show consists of eight experiments to weigh pros and cons of ideas on how to reduce global warming. The projects are as follows:

Seeing if glacier melting on Greenland can be prevented by covering them with insulating sheets.

Led by scientist Mark Hodges, they attempt to reforest areas of bare Earth from helicopters using canisters holding a tree seedling.

Led by atmospheric physicist John Latham and engineer Stephen Salter, the team attempted a Cloud reflectivity enhancement experiment. Their goal was to make clouds more reflective to bounce more of the Sun's heat generating rays back into space as a stop-gap against global warming. By changing the size of water droplets within a cloud, they make clouds brighter and reflect the Sun's heat into space. They choose to seed marine because of their commonality around the world and the fact that they are low-lying, making it easier for man-made droplets to reach them. The Project Earth team uses the potassium chloride and sodium chloride from (salt-based) flares to form droplet particles that are one micrometre in diameter, and that can rise to 300 ft (91 m), even in adverse (cloudless) conditions. The experiment proves that man-made droplets can indeed seed stratocumulus clouds.

The team is also charged with creating a delivery system for the cloud creation mechanisms that allows for low carbon emission, remote controlled vessels. They employ the concept of the Flettner rotor by fabricating rotors and installing them onto a reinforced/retrofitted trimaran.
