What could human being do to prevent further global warming caused by exponentially growing world population? The good news is that, mother nature through the eruption volcanoes are actually trying to help our planet by releasing ‘sulfur dioxide’ into the upper atmosphere, which in return helpful to reduce the average summer temperatures by few Fahrenheit.

According to research data, the eruption of Mt. Pinatubo back in 1991 has successfully added 20 megatons of sulfur dioxide to the upper atmosphere and help to lowered temperatures in Northern Europe by four degrees Fahrenheit.


What could you do in case you are really concern about the present global warming condition? Here are some list of ideas from recent study conducted by Environmental Researchers, which could help to release several megaton of aerosols or heat depleting chemical into the upper atmosphere to cool down our planet’s atmosphere…


Old Airplanes
Modifying a fleet of Boeing 747s for high altitude flight and aerosol delivery would cost just $1.1 billion per year. We’d only need 14 of them, and we could buy used ones on the cheap. However, they max out at about 45,000 feet. Going higher (up to 65,000 feet) would require a fleet of 28 supersonic B-1 bombers at a cost of nearly $5 billion, and for extreme high altitude delivery, we’d need to spend $8.4 billion on 133 F-15s that could “zoom-climb” up to 85,000 feet.

New Airplanes
For the most effective high altitude aerosol deployment, another option would be a new, purpose-built aircraft. The estimated cost for an aircraft capable of releasing five megatons of aerosols at 100,000 feet would be just under $10 billion, but that’s a lot more cargo at a much higher altitude than current aircraft, making for a more effective system.

For heavy cargo lifting and long duration operations, airships could be a good way to go. Hybrid lift helium airships that can deliver one megaton per year of aerosols to 100,000 feet would cost about $2 billion per year.

Rocket Gliders
Rockets are an obvious way to get to high altitudes, and the researchers took a look at a concept vehicle that would use “rocket engines or motors to boost a vehicle and payload to altitude. At apogee, wings are deployed to increase the vehicle’s lift-to-drag coefficient to allow it to glide at altitude and disperse payload. Once dispersal is completed, the wings retract to allow it to descend quickly.” Cool idea, but it would be about a hundred times more expensive than a less exotic system at an estimated $390 billion per year.

Yes, guns. Why not just shoot aerosols into the atmosphere packaged inside exploding artillery shells fired out of an Iowa-class battleship’s 16” Mark 7 naval gun? Sounds like fun to me, but the overall cost would be nearly $140 billion, or $20 billion if the guns were modernized to fire shells electromagnetically (sweet!). Also, the study notes that “these new gun technologies are unlikely to be available for non-military uses for some time to come.” Bummer.

A Hose
We’ve looked at this pipe idea before: you’d take a hose, attach it to a big balloon, send the balloon up to into the air, and then pump aerosols through the hose. Unfortunately, we don’t yet have the materials that we’d need to get this to actually work at the necessary altitudes, but getting us there might cost between $4 and $10 billion.

This might be a stunning discovery, as all these years, many scientists have been blaming for airplane causing more heat release into our atmosphere, not to mention the highly expensive cost of production to get those premium fossil fuel to run those airplanes.
