Infrared radiation serves as a cooling channel when an emitting surface is directly exposed to the atmosphere. However, performance restricted, or it might be transitioned heating mode in enclosure. In this study, we develop design strategy modify emissivity mitigate radiative enclosure comprising of two (i.e., floor and cover) gray bodies. Indoor experiments were performed on copper with view ...

Theoretical models have been used to argue that seasonal mean monsoons will shift abruptly and discontinuously from wet to dry stable states as their radiative forcings pass a critical threshold, sometimes referred to as a "tipping point." Further support for a strongly nonlinear response of monsoons to radiative forcings is found in the seasonal onset of the South Asian summer monsoon, which i...

Changes in solar activity are regularly forwarded as an hypothesis to explain the observed global warming over the last century. The support of such claims is largely statistical, as knowledge of the physical relationships is limited. The statistical evidence is revisited. Changing solar activity is a statistically plausible hypothesis for the observed warming, if short-term natural variability...
