It’s impossible to predict the exact speed and severity with which climate change will unfold, but one thing is clear: if we take no preventive action, eventually we’ll be tempted to take desperate action. And over the decades, as the effects of climate change grow increasingly severe, the amount of risk humankind is willing to bear will increase.

In the next decade, as Dust Bowl–like conditions afflict the American West and it becomes ever more difficult to dismiss the drought as a temporary glitch, low-risk methods for removing carbon dioxide from the atmosphere will start to look attractive...By 2009, NASA climate modelers and biologist Leonard Ornstein estimated that both the Australian outback and the Sahara would have to be transformed into forest to remove meaningful quantities of carbon dioxide. They proposed irrigating both deserts with desalinated seawater and planting them with eucalyptus forests, which could remove as much as 12 billion tons of CO₂ from the atmosphere every year—about a third of the total global emissions in 2010. Nuclear power plants could generate carbon-free electricity for the network of reverse-osmosis desalination plants. This world-historical landscaping project would carry risks. An afforested Sahara could provide a breeding ground for swarms of crop-destroying locusts and flocks of disease-carrying birds. [Wait, now forested bird breeding areas are bad because birds carry disease?!] Because Saharan dust may help suppress Atlantic cyclone formation, the scheme could strengthen hurricanes. [Wait, what?  Now deserts are good because they weaken hurricanes?] The biggest problem, however, may be the $1-trillion-plus annual cost.

Flashback: Scientists Considered Pouring Soot Over the Arctic in the 1970s to Help Melt the Ice – In Order to Prevent Another Ice Age - Washington's Blog

On April 28, 1975, Newsweek wrote an article stating:

Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects. They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve. But the scientists see few signs that government leaders anywhere are even prepared to take the simple measures of stockpiling food or of introducing the variables of climatic uncertainty into economic projections of future food supplies. The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality.
