The ongoing climate change is driven by the greenhouse effect of such radiative gases as CO2. It however has been a challenge to acquire an accurate long-term radiation record, like the Keeling curve of the CO2 concentration, to irrefutably nail down climate change. Lei’s research found that the over 20-years AERI data measured at the SGP site presents such a highly wanted radiative Keeling curve and discloses interesting climate change signals of both CO2 itself (climate forcing) and mid-latitude clouds (climate feedback).
