Accurate diagnosis of regional atmospheric and surface energy budgets is critical for understanding the spatial distribution of heat uptake associated with the Earth's energy imbalance (EEI). This contribution discusses frameworks and methods for consistent evaluation of key quantities of those budgets using observationally constrained data sets. It thereby touches upon assumptions made in data products which have implications for these evaluations.

The global seasonal cycle of energy in Earth's climate system is quantified using observations and reanalyses. After removing long-term trends, net energy entering and exiting the climate system at the top of the atmosphere (TOA) should agree with the sum of energy entering and exiting the ocean, atmosphere, land, and ice over the course of an average year. Achieving such a balanced budget with observations has been challenging.

This study uses an oceanic energy budget to estimate the ocean heat transport convergence in the North Atlantic during 2005-2018. The horizontal convergence of the ocean heat transport is estimated using ocean heat content tendency primarily derived from satellite altimetry combined with space gravimetry. The net surface energy fluxes are inferred from mass-corrected divergence of atmospheric energy transport and tendency of the ECMWF ERA5 reanalysis combined with top-of-the-atmosphere radiative fluxes from the clouds and the Earth's radiant energy system project.

Diseases affecting adipose tissue (AT) function include obesity, lipodystrophy, and lipedema, among others. Both a lack of and excess AT are associated with increased risk for developing diseases including type 2 diabetes mellitus, hypertension, obstructive sleep apnea, and some types of cancer. However, individual risk of developing cardiometabolic and other 'obesity-related' diseases is not entirely determined by fat mass.

Following a decline in the production and use of polychlorinated naphthalenes (PCNs) and the restrictions introduced by the Stockholm Convention, dietary intake represents the most significant pathway of human exposure to these dioxin-like contaminants. PCNs occur ubiquitously in foods, originating from the legacy of historical production that is now globally redistributed, as well as from ongoing industrial and domestic combustion sources which have a stronger influence on occurrence patterns in countries where they were not produced. Recent studies have benefited from a wider set of available PCN reference standards, enabling more accurate reporting of a diverse range of congeners.

Women are known to have twice as much lifetime prevalence of post-traumatic stress disorder (PTSD) as men do. It has been reported that the risk genotype (CC) of a single nucleotide polymorphism (SNP) (rs2267735) in the pituitary adenylate cyclase-activating polypeptide (PACAP-PAC1R) system is associated with PTSD risk and altered fear conditioning and fear extinction in women. Surprisingly, no previous work has studied the effect of this SNP on fear conditioning, extinction, or generalization in non-traumatized/low trauma load women.
