US report urges action amid extreme weather events
A comprehensive US government report has confirmed that extreme weather linked to climate change is worsening despite drops in US greenhouse gas emissions. The report urges further action to mitigate potentially catastrophic consequences. The Fifth National Climate Assessment follows a rash of extreme weather events across the US this year, from deadly wildfires in Maui to intense flooding in the Northeast. The assessment was mandated by the Global Change Research Act of 1990, requiring the US Global Change Research Program to deliver a report every four years. The report describes the increase in extreme weather as “unprecedented over thousands of years” and warns of “large scale changes” in temperature, sea levels, ocean acidification and rainfall patterns, “with a cascade of effects in every part of the country.” (Photo: US Forest Service via Wikimedia Commons)
