In the article, researchers looked at how innovation reacts to climate change by studying patents and greenhouse gas emissions in 70 different countries. They found that the number of climate-related innovations increases as carbon dioxide emissions from gas and liquid fuels go up, but decreases when emissions from solid fuels like coal rise. Surprisingly, the government's financial support doesn't always lead to more climate-friendly technologies being developed. The study suggests that focusing public funds on areas where innovation helps fight climate change could be a smart move.
