TL;DR: In this paper, the authors present estimates of the altimetry-based global mean sea level (average variance of 3.1 +/- 0.3 mm/yr and acceleration of 0.1 mm/r2 over 1993-present), as well as of the different components of the sea level budget over 2005-present, using GRACE-based ocean mass estimates.
Abstract: Global mean sea level is an integral of changes occurring in the climate system in response to
unforced climate variability as well as natural and anthropogenic forcing factors. Its temporal
evolution allows detecting changes (e.g., acceleration) in one or more components. Study of
the sea level budget provides constraints on missing or poorly known contributions, such as
the unsurveyed deep ocean or the still uncertain land water component. In the context of the
World Climate Research Programme Grand Challenge entitled “Regional Sea Level and
Coastal Impacts”, an international effort involving the sea level community worldwide has
been recently initiated with the objective of assessing the various data sets used to estimate
components of the sea level budget during the altimetry era (1993 to present). These data sets
are based on the combination of a broad range of space-based and in situ observations, model
estimates and algorithms. Evaluating their quality, quantifying uncertainties and identifying
sources of discrepancies between component estimates is extremely useful for various
applications in climate research. This effort involves several tens of scientists from about fifty
research teams/institutions worldwide (www.wcrp-climate.org/grand-challenges/gc-sea-
level). The results presented in this paper are a synthesis of the first assessment performed
during 2017-2018. We present estimates of the altimetry-based global mean sea level (average
rate of 3.1 +/- 0.3 mm/yr and acceleration of 0.1 mm/yr2 over 1993-present), as well as of the
different components of the sea level budget (http://doi.org/10.17882/54854). We further
examine closure of the sea level budget, comparing the observed global mean sea level with
the sum of components. Ocean thermal expansion, glaciers, Greenland and Antarctica
contribute by 42%, 21%, 15% and 8% to the global mean sea level over the 1993-present. We
also study the sea level budget over 2005-present, using GRACE-based ocean mass estimates
instead of sum of individual mass components. Results show closure of the sea level budget
within 0.3 mm/yr. Substantial uncertainty remains for the land water storage component, as
shown in examining individual mass contributions to sea level.

TL;DR: In this paper, the authors estimate the long-term oceanic impact of tropical cyclones by inserting realistic wind vortices along observed TCs tracks in a 1/2° resolution ocean general circulation model over the 1978-2007 period.
Abstract: Recent studies suggested that tropical cyclones (TCs) contribute significantly to the meridional oceanic heat transport by injecting heat into the subsurface through mixing. Here, we estimate the long-term oceanic impact of TCs by inserting realistic wind vortices along observed TCs tracks in a 1/2° resolution ocean general circulation model over the 1978–2007 period. Warming of TCs’ cold wakes results in a positive heat flux into the ocean (oceanic heat uptake; OHU) of ~480 TW, consistent with most recent estimates. However, ~2/5 of this OHU only compensates the heat extraction by the TCs winds during their passage. Another ~2/5 of this OHU is injected in the seasonal thermocline and hence released back to the atmosphere during the following winter. Because of zonal compensations and equatorward transport, only one-tenth of the OHU is actually exported poleward (46 TW), resulting in a marginal maximum contribution of TCs to the poleward ocean heat transport. Other usually neglected TC-related processes however impact the ocean mean state. The residual Ekman pumping associated with TCs results in a sea-level drop (rise) in the core (northern and southern flanks) of TC-basins that expand westward into the whole basin as a result of planetary wave propagation. More importantly, TC-induced mixing and air-sea fluxes cool the surface in TC-basins during summer, while the re-emergence of subsurface warm anomalies warms it during winter. This leads to a ~10 % reduction of the sea surface temperature seasonal cycle within TCs basins, which may impact the climate system.

TL;DR: Bard et al. as discussed by the authors proposed an alternative strategy for constraining the rate and magnitude of sea-level change that we might expect by the end of this century by using the geological record, which has long identified examples of nonlinear ice sheet response to climate forcing.
Abstract: Uncertainties in sea-level projections for the 21st century have focused ice sheet modelling efforts to include the processes that are thought to be contributing to the recently observed rapid changes at ice sheet margins. This effort is still in its infancy, however, leaving us unable to make reliable predictions of ice sheet responses to a warming climate if such glacier accelerations were to increase in size and frequency. The geological record, however, has long identified examples of nonlinear ice sheet response to climate forcing (Shackleton NJ, Opdyke ND. 1973. Oxygen isotope and paleomagnetic stratigraphy of equatorial Pacific core V28–239, late Pliocene to latest Pleistocene. Geological Society of America Memoirs145: 449–464; Fairbanks RG. 1989.

TL;DR: In this article, the authors present the results of the groundswell of interest which is currently being manifested among the AACJC institutional membership in the special characteristics, problems, and needs of smaller, rural community junior colleges.
Abstract: This publication is the result of the groundswell of interest which is currently being manifested among the AACJC institutional membership in the special characteristics, problems, and needs of smaller, rural community junior colleges. Such institutions comprise approximately one-half the constituency of the association, and thus their interests and their concerns become those of this organization as a whole. This monograph is published in response to a request of the Task Force on Rural Community Colleges established in 1976 by the board of directors. The views expressed are those of the Task Force members.

TL;DR: Guided by standpoint theory, researchers conducted a case study to identify factors influencing access to Oklahoma's secondary school principalship for four female first-time principals Regardless of equity legislation and increasing numbers of females with advanced degrees, the numbers of men and women who hold secondary school administration positions continue to be disproportionate to their numbers in the teaching profession as discussed by the authors.
Abstract: Guided by Standpoint Theory, researchers conducted this case study to identify factors influencing access to Oklahoma’s secondary school principalship for four female first-time principals Regardless of equity legislation and increasing numbers of females with advanced degrees, the numbers of men and women who hold secondary school administration positions continue to be disproportionate to their numbers in the teaching profession
Three standpoints emerged: In the transition from teacher to administrator, each participant was nurtured by another individual; male sponsors were their primary encouragers; and participants had strong emotional investments in the schools and communities of their employment Aspiring female principals should cultivate strong support systems, seek out mentors, and strengthen their professional networks Accepting stepping-stone administrative positions may be an essential starting point for aspiring female secondary principals; administrative skills can be gained through internships, assistant principal positions, and administrative positions in lower grade levels
