2. Wrap Greenland In A Blanket

Greenland is the largest island in the world, so wrapping it in a blanket sounds wildly impractical – but that is exactly what Dr Jason Box, a glaciologist from Ohio State University, proposes. The professor believes that if the world covers the country’s glaciers with blankets, this will be enough to reflect the sun’s rays and prevent the ice caps from melting. Interestingly, the universities of Innsbruck and Zurich are already using this technology in the Alps on the Zugspitze glacier.

Box and his team have previously tested their theory as part of a Discovery Channel documentary. They used  31 giant rolls of specially designed white polypropylene blankets to cover a total surface area of 10,000 square meters.

Foil wasn’t used because it isn’t good at insulating objects beneath it.  The blankets absorb this heat above the blanket and stops it from reaching the ice below, keeping it intact.

3. Make More Clouds

Last year NASA and Bill Gates teamed up to hatch plans for a seawater-spraying machine that could prevent climate change by creating clouds that reflect sunlight away from earth. The machines could suck up ten tons of water per second and then spray it over 3,000 feet into the air, increasing the density of clouds. Although the plan would help to mitigate climate change, it would take a large amount of energy to power each individual ship – and a study showed that it would it take 1,900 ships at a cost of over $7 billion to stop Earth’s temperature from rising.

    It is likely that a change in communication between the mediterranean and Atlantic can cause a change in Atlantic climate, but I doubt this could affect significantly and more positively the Canada climate (?freezing) than other areas (and negatively). What’s about effects on the local climate and environmental? Nobody can predict enough accurately the small and large scale effects of such a risky project, and nobody in current and future generations will like to pay for (bad)consequencies.

    Then, lowering the mediterranean level by 200m thanks to evaporation only would take several years with lower energy production at a time the demand of energy is high… Then the dam will be ageing or obsolete…

    Finally, closing mediterrannean and using it to evaporate the atlantic water fed for energy production, would make it a sink for salt. Why creating new inlands if they are dead (or costly to desalt)?

    In a similar way, a peruvian NGO is already painting the peruvian Andes glaciers with a special ecological paint based in white lime: https://www.facebook.com/glaciares.peru
