Ideas for worldwide engineering projects that aim to stop global warming have been around for years, but are they really worth trying?

What Is Geoengineering and Why Is It Considered a Climate Change Solution?
“Today, with climate change accelerating and little being done to curb the greenhouse gas emissions, some scientists have resurrected the idea of “deliberate large-scale manipulation of the planetary environment,” as the U.K.’s Royal Society puts it. After all, it’s an idea nearly as old as the understanding of the physical principles behind global warming itself.”
Could Space Mirrors Stop Global Warming?
“Lowell Wood of Lawrence Livermore National Laboratory proposed a giant space mirror in the early 2000s, though he cautioned that the mirror should be considered only as a measure of last resort. Why? Because the mirror would have to have an area of 600,000 square miles – a slightly smaller area than Greenland – and launching something that big would be prohibitively expensive.”
A Massive Renewable Energy Push Is Needed to Avoid Catastrophic Climate Change
“A new report suggests that the goal of the Paris Climate Agreement to limit global warming to 2 degrees Celsius (or less) above pre-industrial temperatures is well within reach – but only if half of the world’s energy supply is sourced from renewables by 2060.”
