The climate keeps getting hotter, and officials around the world are failing to rise to the task of tackling emissions to ensure a future for our kids and grandkids. Amid this backdrop, an international team of experts suggests reflecting sunlight back into space could help keep the warming under control. Image via Pixabay. The team focused on exploring the potential benefits and shortcomings of using various technological means of reflecting sunlight away from our planet — which should help cool it down. This approach, known as solar radiation modification (SRM), should be much cheaper and more cost-effective than our other current alternatives. Together with reductions in greenhouse gas emissions, an SRM-type program could help mitigate or even counter the warming trend that started in the Industrial Revolution.
