Pam Pearson, ICCI's founder and director, introduced the report on the risks of irreversible climate change in the cryosphere − the scientific name for the parts of the world that are covered in ice and snow for part or all of the year — by saying: «We are worried by the disconnect between
cryosphere dynamics and the policy response.»
This consensus - driven view, which emerged from sharing data related to
cryosphere dynamics, was needed to enhance U.S. - China collaborations.
Not exact matches
Among the ice sheet
dynamics to fret about I see this change in the temperature of the ice from say -30 C to ice - at - 0C and the subsequent uptake of the heat to go from ice - at - 0C to water - at - 0C as the «dark matter» of the
cryosphere.
Technically they should coincide every 1,100,000 years (the least common multiple of 100,000 and 22,000)-- but the cycles are not exactly 100,000 and 22,000 — and the time actually varies slightly depending on extraterrestial forces (the other planets) and internal Earth
dynamics (position of tectonic plates,
cryosphere, core flows?).
Coverage includes original paleoclimatic, diagnostic, analytical and numerical modeling research on the structure and behavior of the atmosphere, oceans,
cryosphere, biomass and land surface as interacting components of the
dynamics of global climate.
Global and local sea level changes: the interaction of multipleparametres (hydrosphre,
cryosphere, lithosphere, ocean
dynamics and climate).
The polar - orbiting Nimbus 5 satellite, launched in 1972, yielded the earliest all - weather, all - season imagery of global sea ice, using microwave instruments (Parkinson et al., 1987), and enabled a major advance in the scientific understanding of the
dynamics of the
cryosphere.
Which suggests the internal
dynamics of the system (ocean, atmosphere and
cryosphere) is still beyond our understanding.
In order of seniority, the seven feedbacks that seem outstanding are: Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to
cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological
dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, etc..
As such, it could significantly affect the
dynamics of the
cryosphere.
