New modelling suggests estimates for methane’s role in global warming are on the low side. Richard A Lovett reports.
Scientists seeking to refine our understanding of global climate change have found that methane is a significantly stronger greenhouse gas than previously suspected. They have also discovered that it has particularly strong climate-warming effects on certain parts of the globe, including Australia’s deserts.
The finding evolved, in part, from data collected by astronomers studying Jupiter and Saturn’s moon Titan. And it comes, ironically, just days after US President Donald Trump’s latest move to reduce regulations on methane emissions from U.S. oil and gas fields.
Like carbon dioxide, methane has long been known to warm the atmosphere by absorbing infrared…
