“…A more novel temporal linkage is noted in Li et al. (2022) who found temporal oscillations of atmospheric pressure led to a pumping effect on atmospheric moisture in the vadose zone in soils.…”

“…Turner et al (2021) noted substantial temporal lags in wetland methane fluxes in response to wetting changes while Yun et al (2022) reported a reversing of carbon dioxide uptake to source observed from decadal flux measurements on the Tibetan Plateau arising from a trend of warming soil temperatures promoting high emissions events outside the growing season. A more novel temporal linkage is noted in Li et al (2022) who found temporal oscillations of atmospheric pressure led to a pumping effect on atmospheric moisture in the vadose zone in soils.…”

Viewed from billions of kilometers away in space, Earth appears as a single "Pale Blue Dot," in the immortalized phrase of Carl Sagan bestowed upon the image taken by the Voyager 1 space probe. Coming closer, though, a sharper image emerges (Figure 1).One finds structure to that dot, shades of green and brown continents, a dark ocean, a bright cryosphere, and a hazy, thin blue atmosphere. Zooming further in, those components break into patterns of mountains and rivers, seas and bays, forests and grasslands, layers, and cloud decks. And getting closer, one finds each component has oscillations and variations of branches and rivulets, canyons and plateaus, currents and coastlines. These objects keep revealing more structure in finer, often self-similar form, like Mandelbrot's fractals, down to eddies and organisms, and further into leaves, cells, enzymes, molecules, and atoms.And then, if you wait seconds, days, decades, or eons, landscape patterns change. Bigger things typically take longer than smaller ones. As a result, the pattern changes-sometimes occurring slowly and subtly, ebbing and flowing in an oscillatory manner, or they can occur quickly and abruptly, morphing into a new state of order.Each element and its dynamics come with variations in space and time that can be encompassed by the concept of scale. Earth systems science is preoccupied with the interactions of these elements, which cannot be understood without a stipulation of the scales of interest (Ge et al., 2019). The most straightforward of these interactions are ones where common processes at all scales can be defined by a single relationship, often a power-law, leading to the concept of scale invariance (Paleri et al., 2022). The most interesting interactions are the ones that break those rules and lead to "upscale" and "downscale" behavior, whereby processes at one scale determine the shape and function of another scale. These are most common at the intersections of biology, hydrology, geology, and meteorology, often within what is termed the "critical zone." This interlocking also harkens to the origins of

“…Under the background of AP variation, earth-air activity is widespread on land [ 22 , 23 ]. For cultural relics in caves, the effect of alternating dry and wet conditions of the atmospheric environment can lead to repeated crystallization of salt at the interface of wall paintings, thereby changing the structure of the wall paintings and causing salt-related deterioration [ 24 , 25 ], the most representative example of which is efflorescence [ 26 ].…”

“…Under the influence of AP fluctuation, the rise and fall of earth-air can cause frequent exchange between the atmosphere and earth-air, leading to frequent alternation between dry and wet air. There is ‘fingerprint’ evidence of exchange between AP and the humidity of earth-air [ 23 ]. Therefore, earth-air activity can influence the cave environment, and vice versa.…”
