Harvard scientists want to limit how much sunlight reaches Earth's surface in order to curb global warming

Climate change is one of the greatest challenges mankind has faced up until now.

How we'll be able to curtail global warming and its devastating consequences is still very much a hot potato among politicians and scientists alike — and so far, the outcome of all these debates hasn't been particularly fruitful.

How we can curb the devastating effects of climate
change is still hotly debated among politicians and
scientists alike.

However, researchers at Harvard may have come up with a solution that sounds just a little too good to be true.

In conjunction with researchers from MIT and Princeton, the group has suggested slowing down global warming by diminishing the amount of sunlight that reaches Earth's surface.

Barack Obama on food and climate change: ‘We can still act and it won’t be too late

During the course of my presidency, I made climate change a top priority, because I believe that, for all the challenges that we face, this is the one that will define the contours of this century more dramatically perhaps than the others. No nation, whether it’s large or small, rich or poor, will be immune from the impacts of climate change. We are already experiencing it in America, where some cities are seeing floods on sunny days, where wildfire seasons are longer and more dangerous, where in our arctic state, Alaska, we’re seeing rapidly eroding shorelines, and glaciers receding at a pace unseen in modern times.

Barack Obama - The former president
addresses the greatest challenges facing
 the world, and what we can do about them

Over my eight years in office, we dramatically increased our generation of clean energy, we acted to curtail our use of dirty energy, and we invested in energy efficiency across the board. At the 2015 climate change summit in Paris, we helped lead the world to the first significant global agreement for a low-carbon future.

Sea-level rise, erosion, coastal flooding greatest human challenge

Many island homes are close to sea level.

Sea-level rise, erosion and coastal flooding are some of the greatest challenges facing humanity from climate change.

Recently at least five reef islands in the remote Solomon Islands have been lost completely to sea-level rise and coastal erosion, and a further six islands have been severely eroded.

These islands lost to the sea range in size from one to five hectares. They supported dense tropical vegetation that was at least 300 years old. Nuatambu Island, home to 25 families, has lost more than half of its habitable area, with 11 houses washed into the sea since 2011.

This is the first scientific evidence, published in Environmental Research Letters, that confirms the numerous anecdotal accounts from across the Pacific of the dramatic impacts of climate change on coastlines and people.
