The Earth’s climate system may be more sensitive to increasing amounts of greenhouse gases than several recent studies have found, which implies that steeper and faster emissions cuts will be necessary to keep warming below dangerous levels. The new research, which appeared this week in the journal Nature Climate Change, questions a central assumption of most of the studies investigating a scientific concept generally referred to as “climate sensitivity.”
The research found that the Earth is likely to experience nearly 20% more warming over the next several decades than past estimates have projected. Those previous studies were based in large part on recent surface temperature trends.
Climate sensitivity and a related measure known as the “transient climate response" are both metrics that capture how much the planet will warm in response to increases in manmade greenhouse gas emissions and other pollutants.
