- Israeli sunshade: Size of Argentina to fight global warming.
- Target: Cut Earth's temperature by 2.7°F in 2 years.
- Critics cite costs; team seeks $20M for 2027 prototype.
The audacious proposal suggests that this one-million-square-mile shade could potentially decrease the Earth's temperature by 2.7 degrees Fahrenheit within a span of two years.
The research team is actively seeking funding, aiming to secure up to $20 million to create a prototype spanning 100 square feet by the year 2027. The envisioned 'sail' would be positioned more than nine million miles away from Earth and would traverse through space by opening and closing its shading layer.
While the proposal has garnered attention for its innovative approach, critics are raising concerns about the staggering cost associated with the project. The estimated expenses for the Israeli-designed 'megastructure' are anticipated to reach trillions. Harvard physicist Avi Loeb commented on the financial aspect, stating, "Erecting any of these 'megastructures' in space would be very expensive and require a major international collaboration through reallocation of funds from military budgets to peaceful purposes."
This concept of dimming or blocking the sun to cool the Earth has been explored by various scientists over the years. In 2021, a $3 million initiative backed by Bill Gates proposed the idea of spraying millions of tons of chalk into the stratosphere. Additionally, the White House announced its openness to plans aimed at blocking sunlight from hitting the Earth's surface as a measure to combat global warming.
While these proposals are still in the experimental stages, the Israeli team is optimistic about achieving a prototype within the next three years. The project represents a bold and unconventional approach to climate control, sparking both excitement and skepticism within the scientific community and beyond.
