What if low-emission and non-emission vehicles are too little, too late to have much effect on global warming? The “Wall
Street Journal’s” Robert Hotz looks at proposals from the scientific fringe that might be cheaper and more effective. The 1991 eruption of Mt. Pinatubo, for example, spewed enough sulfates into the air to lower global temperatures by one degree. An artificial haze of sulfates may be just as effective in the short run. Trillions of orbiting mirrors could reflect sunlight. Hotz finds that few of these ideas are gaining traction because even with a cooler planet, carbon dioxide would continue to leach into oceans, making them more acidic.
Also, rainfall patterns across the planet would be disrupted.
