Research news - Earth s vital signs worsen amid business-as-usual mindset on climate change

Earth’s vital signs worsen amid business-as-usual mindset on climate change Twenty months after declaring a climate emergency and establishing a set of vital signs for the Earth, a coalition of researchers says “unrelenting business as usual” has led to alarming results. The international team – led by Oregon State University (OSU) and including the Global Systems Institute (GSI) at the University of Exeter – track 31 vital signs, and their latest paper finds record-breaking results in 18 of these. Records include highest-ever concentrations of key greenhouse gases carbon dioxide, methane and nitrous oxide, and lowest-ever ice mass in Greenland and Antarctica. Ruminant livestock (such as cows and sheep) are at record levels – now numbering more than four billion, with a total mass exceeding that of all humans and wild land mammals combined.
